I have a form with a submitbutton which will get results from a database and updates a listview based on these results. If there is no result, a feedback message is shown. This all works fine.
Now I want to replace the submitlink with an IndicatingAjaxButton, so the user can see something happening when getting the result takes a long time.
The basic idea is this:
IndicatingAjaxButton submitLink = new IndicatingAjaxButton("submit", form) {
private static final long serialVersionUID = -4306011625084297054L;
#Override
public void onSubmit(AjaxRequestTarget target, Form<?> form) {
Integer hourFrom = 0;
Integer hourTo = 0;
Integer minuteFrom = 0;
Integer minuteTo = 0;
hourFrom = Integer.parseInt(hour_from.getModelObject());
hourTo = Integer.parseInt(hour_to.getModelObject());
minuteFrom = Integer.parseInt(minute_from.getModelObject());
minuteTo = Integer.parseInt(minute_to.getModelObject());
Calendar from = Calendar.getInstance();
Calendar to = Calendar.getInstance();
Date dateFrom = date_from.getModelObject();
Date dateTo = date_to.getModelObject();
from.setTime(dateFrom);
to.setTime(dateTo);
from.set(Calendar.HOUR, hourFrom);
from.set(Calendar.MINUTE, minuteFrom);
to.set(Calendar.HOUR, hourTo);
to.set(Calendar.MINUTE, minuteTo);
if (topicQueueSelect.getModelObject() == null) {
error("Please select a message name.");
getSession().setAttribute("error", "");
}
if (to.before(from)) {
error("Date to must be after date from.");
getSession().setAttribute("error", "");
}
cal.setTimeInMillis(System.currentTimeMillis());
if (from.after(cal)) {
error("Date from must be in the past.");
getSession().setAttribute("error", "");
}
if (getSession().getAttribute("error") != null) {
getSession().removeAttribute("error");
return;
}
page.setModelObject(1);
List<Search> searchFields = (List<Search>) searchFieldsField
.getModelObject();
messageKeyDataList = messageController.search(
topicQueueSelect.getModelObject(), searchFields,
from.getTime(), to.getTime(),
maxResults.getModelObject(), page.getModelObject(),
sortorder);
if (messageKeyDataList.size() == 0) {
info("Search criteria didn't produce any results.");
result.setList(messageKeyDataList);
resultContainer.setVisible(false);
return;
}
resultContainer.setVisible(true);
resultSize = messageController.getResultSize();
int pages = (int) Math.ceil((float) resultSize
/ maxResults.getModelObject());
ArrayList<Integer> pageNumbers = new ArrayList<Integer>();
for (int n = 1; n <= pages; n++) {
pageNumbers.add(n);
}
page.setChoices(pageNumbers);
pageunder.setChoices(pageNumbers);
showing.setDefaultModelObject("Showing 1 to "
+ messageKeyDataList.size() + " out of " + resultSize
+ " messages");
lastSearch.put("topicQueue", topicQueueSelect.getModelObject());
lastSearch.put("searchFields", searchFields);
lastSearch.put("from", from.getTime());
lastSearch.put("to", to.getTime());
lastSearch.put("maxResults", maxResults.getModelObject());
result.setList(messageKeyDataList);
target.add(feedback);
}
};
The SubmitLink does show me either the ResultView with the new list, or the info message, the IndicatingAjaxButton doesn't. I know the form submit is called, because the system.out is being printed.
Any suggestions on this?
SubmitLink is non-Ajax component. Using it will repaint the whole page!
IndicatingAjaxButton is an Ajax component. You need to use the passed AjaxRequestTarget to add components which should be repainted with the Ajax response. For example the FeedbackPanel should be added to the AjaxRequestTarget.
I found that I had to do setOutputMarkupPlaceholderTag(true) on both the resultContainer and the feedback. After that adding them to the requesttarget works as expected.

I am trying to create a dynamic tablelayout which creates adds a skill and gives that skill 1 level and a increase decrease button. I am struggling with having the buttons access the level label. I thought about finding the location of the button that was clicked, but could figure out how to do that.
In advance, Thank you.
example:
1
this is what i have so far:
private void skilladded(object sender, EventArgs e)
{
int i = 1;
int[] position= { 0,0};
bool test = false;
//string select;
int k=0;
for (i=1;i<=skillstableLayoutPanel.RowCount;i++)
{
Control c= skillstableLayoutPanel.GetControlFromPosition(0,i);
if (c!=null&&addskillswin.selected==c.Text)
{
test = true;
k = i;
break;
}
else if(c==null)
{
k = i;
break;
}
}
if (test==false)
{
Label newskill = new Label();
Label newskilllvl = new Label();
TableLayoutPanel buttontable = new TableLayoutPanel();
Button up = new Button();
Button down = new Button();
buttontable.ColumnCount = 2;
buttontable.RowCount = 1;
buttontable.RowStyles.Add(new RowStyle(SizeType.Percent,100f));
buttontable.ColumnStyles.Add(new ColumnStyle(SizeType.Percent,50f));
buttontable.ColumnStyles.Add(new ColumnStyle(SizeType.Percent, 50f));
buttontable.Margin = new Padding(0,0,0,0);
buttontable.Dock = DockStyle.Fill;
buttontable.Controls.Add(up, 0, 0);
buttontable.Controls.Add(down, 1, 0);
up.BackgroundImage = Properties.Resources.up;[enter image description here][2]
down.BackgroundImage = Properties.Resources.down;
up.BackgroundImageLayout=ImageLayout.Stretch;
down.BackgroundImageLayout = ImageLayout.Stretch;
newskill.Text = addskillswin.selected;
newskilllvl.Text = "1";
up.Margin = new Padding(0, 0, 0, 0);
down.Margin = new Padding(0, 0, 0, 0);
skillstableLayoutPanel.Controls.Add(newskill,0,k);
skillstableLayoutPanel.Controls.Add(newskilllvl, 1, k);
skillstableLayoutPanel.Controls.Add(buttontable, 2, k);
skillavaillabel.Text = (Convert.ToInt32(skillavaillabel.Text) - 1).ToString();
skillpointlvl = Convert.ToInt32(newskilllvl.Text);
up.MouseClick += new MouseEventHandler(skillup);
down.MouseClick += new MouseEventHandler(skilldown);
}
if (test==true)
{
skillstableLayoutPanel.GetControlFromPosition(1, k).Text = (Convert.ToInt32(skillstableLayoutPanel.GetControlFromPosition(1, k).Text) + 1).ToString();
skillavaillabel.Text = (Convert.ToInt32(skillavaillabel.Text) -1).ToString();
}
}
private void skillup(object sender, EventArgs e)
{
skillpointlvl++;
}
private void skilldown(object sender, EventArgs e)
{
skillpointlvl--;
}
Instead of this:
up.MouseClick += new MouseEventHandler(skillup);
down.MouseClick += new MouseEventHandler(skilldown);
Try something like this:
up.MouseClick += ((o, me) =>
{
int currentLevel = Int32.Parse(newskilllvl.Text);
currentLevel++;
newskilllvl.Text = currentLevel.ToString();
});
down.MouseClick += ((o, me) =>
{
int currentLevel = Int32.Parse(newskilllvl.Text);
currentLevel--;
newskilllvl.Text = currentLevel.ToString();
});
Your skillup or skilldown event handler could potentially process each sender and see from which button the click originated, but you'd have to uniquely name each button and do a lot of string comparisons to see which button corresponds to which skill level label. The code above adds an anonymous handler to each button, which allows us to essentially tie the button being clicked to its corresponding skill label.
Personally though, I would not store all these values in labels like you have done. I would either store them in properties on the form, or better yet in a class of their own. I would also put all this logic somewhere else beside the form, like in a Presenter or Controller (or class library), and follow a design pattern such as MVC or MVP. This will make maintaining and changing the application easier in the long run.
Also, consider using camel case and Pascal case for your variable names. All lowercase variables are harder for experienced programmers to read.
I am trying to do a validation on a textbox that can allow the input of one or more phone number in a single textbox. What I am trying to do is to send an message to the phone numbers included in the textbox.
I have no problem when I enter just one set of number into the textbox and the message can be sent.
However, whenever I type two sets of digit into the same textbox, my validation error will appear.
I am using user controls and putting the user control in a listview.
Here are my codes:
private ObservableCollection<IFormControl> formFields;
internal ObservableCollection<IFormControl> FormFields
{
get
{
if (formFields == null)
{
formFields = new ObservableCollection<IFormControl>(new List<IFormControl>()
{
new TextFieldInputControlViewModel(){ColumnWidth = new GridLength(350) ,HeaderName = "Recipient's mobile number *" , IsMandatory = true, MatchingPattern = #"^[\+]?[1-9]{1,3}\s?[0-9]{6,11}$", Tag="phone", ContentHeight = 45, ErrorMessage = "Please enter recipient mobile number. "},
});
}
return formFields;
}
}
And here is the codes for the button click event:
private void OkButton_Click(object sender, RoutedEventArgs e)
{
MessageDialog clickMessage;
UICommand YesBtn;
int result = 0;
//Fetch Phone number
var phoneno = FormFields.FirstOrDefault(x => x.Tag?.ToLower() == "phone").ContentToStore;
string s = phoneno;
string[] numbers = s.Split(';');
foreach (string number in numbers)
{
int parsedValue;
if (int.TryParse(number, out parsedValue) && number.Length.Equals(8))
{
result++;
}
else
{ }
}
if (result.Equals(numbers.Count()))
{
try
{
for (int i = 0; i < numbers.Count(); i++)
{
Class.SMS sms = new Class.SMS();
sms.sendSMS(numbers[i], #"Hi, this is a message from Nanyang Polytechnic School of IT. The meeting venue is located at Block L." + Environment.NewLine + "Click below to view the map " + Environment.NewLine + location);
clickMessage = new MessageDialog("The SMS has been sent to the recipient.");
timer = new DispatcherTimer();
timer.Interval = TimeSpan.FromSeconds(1);
timer.Tick += timer_Tick;
timer.Start();
YesBtn = new UICommand("Ok", delegate (IUICommand command)
{
timer.Stop();
idleTimer.Stop();
var rootFrame = (Window.Current.Content as Frame);
rootFrame.Navigate(typeof(HomePage));
rootFrame.BackStack.Clear();
});
clickMessage.Commands.Add(YesBtn);
clickMessage.ShowAsync();
}
}
catch (Exception ex)
{ }
}
}
I am trying to separate the two numbers with ";" sign.... and I am wondering if that is the problem. Or maybe it is the matchingpattern that I have placed in.
The answer is quite simple, create a bool property in your TextFieldInputControlViewModel something like
public bool AcceptMultiple {get;set;}
and to keep things dynamic, create a char property as a separator like below:
public char Separator {get;set;}
Now, modify your new TextFieldInputControlViewModel() code statement by adding values to your new fields like below:
new TextFieldInputControlViewModel(){Separator = ';', AcceptMultiple = true, ColumnWidth = new GridLength(350) ,HeaderName = "Recipient's mobile number *" , IsMandatory = true, MatchingPattern = #"^[\+]?[1-9]{1,3}\s?[0-9]{6,11}$", Tag="phone", ContentHeight = 45, ErrorMessage = "Please enter recipient mobile number. "},
Once it's done, now in your checkValidation() function (or where you check the validation or pattern match) can be replaced with something like below:
if(AcceptMultiple)
{
if(Separator == null)
throw new ArgumentNullException("You have to provide a separator to accept multiple entries.");
string[] textItems = textField.Split(Separator);
if(textItems?.Length < 1)
{
ErrorMessage = "Please enter recipient mobile number." //assuming that this is your field for what message has to be shown.
IsError = true; //assuming this is your bool field that shows all the errors
return;
}
//do a quick check if the pattern matching is mandatory. if it's not, just return.
if(!IsMandatory)
return;
//your Matching Regex Pattern
Regex rgx = new Regex(MatchingPattern);
//loop through every item in the array to find the first entry that's invalid
foreach(var item in textItems)
{
//only check for an invalid input as the valid one's won't trigger any thing.
if(!rgx.IsMatch(item))
{
ErrorMessage = $"{item} is an invalid input";
IsError = true;
break; //this statement will prevent the loop from continuing.
}
}
}
And that'll do it.
I've taken a few variable names as an assumption as the information was missing in the question. I've mentioned it in the comments about them. Make sure you replace them.
I am seeing errors while exporting email in office 365 account using ews managed api, "The server cannot service this request right now. Try again later." Why is that error occurring and what can be done about it?
I am using the following code for that work:-
_GetEmail = (EmailMessage)item;
bool isread = _GetEmail.IsRead;
sub = _GetEmail.Subject;
fold = folder.DisplayName;
historicalDate = _GetEmail.DateTimeSent.Subtract(folder.Service.TimeZone.GetUtcOffset(_GetEmail.DateTimeSent));
props = new PropertySet(EmailMessageSchema.MimeContent);
var email = EmailMessage.Bind(_source, item.Id, props);
bytes = new byte[email.MimeContent.Content.Length];
fs = new MemoryStream(bytes, 0, email.MimeContent.Content.Length, true);
fs.Write(email.MimeContent.Content, 0, email.MimeContent.Content.Length);
Demail = new EmailMessage(_destination);
Demail.MimeContent = new MimeContent("UTF-8", bytes);
// 'SetExtendedProperty' used to maintain historical date of items
Demail.SetExtendedProperty(new ExtendedPropertyDefinition(57, MapiPropertyType.SystemTime), historicalDate);
// PR_MESSAGE_DELIVERY_TIME
Demail.SetExtendedProperty(new ExtendedPropertyDefinition(3590, MapiPropertyType.SystemTime), historicalDate);
if (isread == false)
{
Demail.IsRead = isread;
}
if (_source.RequestedServerVersion == flagVersion && _destination.RequestedServerVersion == flagVersion)
{
Demail.Flag = _GetEmail.Flag;
}
_lstdestmail.Add(Demail);
_objtask = new TaskStatu();
_objtask.TaskId = _taskid;
_objtask.SubTaskId = subtaskid;
_objtask.FolderId = Convert.ToInt64(folderId);
_objtask.SourceItemId = Convert.ToString(_GetEmail.InternetMessageId.ToString());
_objtask.DestinationEmail = Convert.ToString(_fromEmail);
_objtask.CreatedOn = DateTime.UtcNow;
_objtask.IsSubFolder = false;
_objtask.FolderName = fold;
_objdbcontext.TaskStatus.Add(_objtask);
try
{
if (counter == countGroup)
{
Demails = new EmailMessage(_destination);
Demails.Service.CreateItems(_lstdestmail, _destinationFolder.Id, MessageDisposition.SaveOnly, SendInvitationsMode.SendToNone);
_objdbcontext.SaveChanges();
counter = 0;
_lstdestmail.Clear();
}
}
catch (Exception ex)
{
ClouldErrorLog.CreateError(_taskid, subtaskid, ex.Message + GetLineNumber(ex, _taskid, subtaskid), CreateInnerException(sub, fold, historicalDate));
counter = 0;
_lstdestmail.Clear();
continue;
}
This error occurs only if try to export in office 365 accounts and works fine in case of outlook 2010, 2013, 2016 etc..
Usually this is the case when exceed the EWS throttling in Exchange. It is explain in here.
Make sure you already knew throttling policies and your code comply with them.
You can find throttling policies using Get-ThrottlingPolicy if you have the server.
One way to solve the throttling issue you are experiencing is to implement paging instead of requesting all items in one go. You can refer to this link.
For instance:
using Microsoft.Exchange.WebServices.Data;
static void PageSearchItems(ExchangeService service, WellKnownFolderName folder)
{
int pageSize = 5;
int offset = 0;
// Request one more item than your actual pageSize.
// This will be used to detect a change to the result
// set while paging.
ItemView view = new ItemView(pageSize + 1, offset);
view.PropertySet = new PropertySet(ItemSchema.Subject);
view.OrderBy.Add(ItemSchema.DateTimeReceived, SortDirection.Descending);
view.Traversal = ItemTraversal.Shallow;
bool moreItems = true;
ItemId anchorId = null;
while (moreItems)
{
try
{
FindItemsResults<Item> results = service.FindItems(folder, view);
moreItems = results.MoreAvailable;
if (moreItems && anchorId != null)
{
// Check the first result to make sure it matches
// the last result (anchor) from the previous page.
// If it doesn't, that means that something was added
// or deleted since you started the search.
if (results.Items.First<Item>().Id != anchorId)
{
Console.WriteLine("The collection has changed while paging. Some results may be missed.");
}
}
if (moreItems)
view.Offset += pageSize;
anchorId = results.Items.Last<Item>().Id;
// Because you’re including an additional item on the end of your results
// as an anchor, you don't want to display it.
// Set the number to loop as the smaller value between
// the number of items in the collection and the page size.
int displayCount = results.Items.Count > pageSize ? pageSize : results.Items.Count;
for (int i = 0; i < displayCount; i++)
{
Item item = results.Items[i];
Console.WriteLine("Subject: {0}", item.Subject);
Console.WriteLine("Id: {0}\n", item.Id.ToString());
}
}
catch (Exception ex)
{
Console.WriteLine("Exception while paging results: {0}", ex.Message);
}
}
}
I'm using the GridView control in WP7 to show records from isolated storage. I'm displaying these
records at page load event of the page. The GridViewPage has 4 columns originally
but when I come back to GridViewPage visiting other page the gridview
showing duplicate columns( 8 columns this time).
Next time again I come back to GridViewPage it is showing 12 columns,
but I don't see any changes in the corresponding XAML page.
But one thing before assigning value to ItemSource of the gridView I'm storing records from the isostore into one IList varialbe making some changes and assigning that IList variable to ItemSource of GridView.
private void GridViewPage_load(object sender, RoutedEventArgs r)
{
System.Windows.Threading.DispatcherTimer dt = new System.Windows.Threading.DispatcherTimer();
dt.Interval = new TimeSpan(0, 0, 0, 1,0); // 1 seconds
dt.Tick += new EventHandler(dt_Tick);
dt.Start();
}
void dt_Tick(object sender, EventArgs e)
{
IList rawList = DBHelperMeeting.GetData();
int count = rawList.Count;
for (int i = 0; i < count; i++)
{
/* in following lines i've written logic to get date and start_time from
table records stored in IList variable-rawList and forming a DateTime
variable
*/
string endDate =Convert.ToDateTime(rawList.ElementAt(i).Date.ToString()).ToShortDateString();
endDate += " "+rawList.ElementAt(i).End_Time;
string startDate = Convert.ToDateTime(rawList.ElementAt(i).Date.ToString()).ToShortDateString();
startDate+=" "+rawList.ElementAt(i).Start_Time;
if ((bool)rawList.ElementAt(i).Flag == true)
{
TimeSpan st = Convert.ToDateTime(startDate) - DateTime.Now;
//MessageBox.Show(st.ToString());
TimeSpan et = Convert.ToDateTime(endDate) - DateTime.Now;
//MessageBox.Show(et.ToString());
if (st.Seconds < 0)
{
if (et.Seconds < 0)
{
rawList.ElementAt(i).Flag = false;
rawList.ElementAt(i).Rem_Time = "Meeting Finished";
}
else
{
rawList.ElementAt(i).Rem_Time = "Meeting Started";
}
}
else if (st.Minutes > 0 && ((st.Hours * 60) + (st.Minutes)) < 16)
{
rawList.ElementAt(i).Rem_Time = st.Minutes.ToString() + " Min.";
}
}
}
GridView1.ItemsSource = rawList;
}
Actually i want to update the Rem_Time field of each record( i.e. meeting) according to time ( Rem_Time shows the remaining time for meeting)
Loaded event is raised all the time when all page components are loaded, even when you come back from another page. You need to load elements in constructor, for example.
I have created a JTable, the table contains 4 rows, and for a specific row, I have overridden the sorting and its working fine only on that column.
Status Scheduled Date Scheduled time Status
false 30/01/2012 02:00:00 Scheduled
false 29/01/2012 14:58:00 Scheduled
false 29/01/2012 15:50:00 Scheduled
For Scheduled Date, which I try to sort, it would sort, but the respecitve rows are not being updated.
Here is my code for sorting
public static void sortColumn(DefaultTableModel model, int colIndex,
boolean sortingOrder) {
Vector<?> data = model.getDataVector();
Object[] colData = new Object[model.getRowCount()];
SortedSet<Object> dataCollected = null;
List<Date> dateCollected;
boolean dateFlag = false;
dateCollected = new ArrayList<Date>();
// Copy the column data in an array
for (int i = 0; i < colData.length; i++) {
Object tempData = ((Vector<?>) data.get(i)).get(colIndex);
if ((colIndex == 1 || colIndex == 4)
&& tempData.toString().contains("/")) {
String[] _scheduledDate1 = ((String) tempData).split("/");
Calendar _cal1 = Calendar.getInstance();
_cal1.set(Integer.parseInt(_scheduledDate1[2]),
Integer.parseInt(_scheduledDate1[1]) - 1,
Integer.parseInt(_scheduledDate1[0]));
dateCollected.add(_cal1.getTime());
dateFlag = true;
} else {
colData[i] = ((Vector<?>) data.get(i)).get(colIndex);
}
}
// DateCompare compare = new DateCompare();
if (!dateFlag) {
dataCollected = new TreeSet<Object>();
dataCollected.add(colData);
dateFlag = false;
}
// Copy the sorted values back into the table model
if ((colIndex == 1 || colIndex == 4) && dateFlag) {
SimpleDateFormat sdf = new SimpleDateFormat("dd/MM/yyyy");
sortOrder = !sortOrder;
if (sortOrder) {
Collections.sort(dateCollected);
} else {
Collections.sort(dateCollected, Collections.reverseOrder());
}
colData = dateCollected.toArray();
for (int i = 0; i < colData.length; i++) {
((Vector<Object>) data.get(i)).set(colIndex,
sdf.format(((Date) colData[i]).getTime()));
}
} else {
for (int i = 0; i < colData.length; i++) {
((Vector<Object>) data.get(i)).set(colIndex, colData[i]);
}
}
model.fireTableStructureChanged();
}
How to I get the entire row update accordingly?
I found the problem, my object against I was comparing was wrong, I've change the code for the same it all works fine.
I implemented QuickSort algorithm to sort the vector on the specific column I need.
