I have a ListGrid with 3 columns, one is hidden but it doesn't change anything to the problem.
I want to group on the value of the 3rd and hidden field, a date. When this Date is not present (null) I want to put the record in the "Actual Projects" group else they go in the "Closed projects" group.
It works BUT I want to have the group Actual Project first and I try a lot of thing with the sort direction of the field and the grid and also with baseTitle I return. It never change I always have the group with the non null value first.
Am I missing something? Is there somebody who experienced with group order?
final int groupClosed = 2;
final int groupActual = 1;
colonneDate.setGroupValueFunction(new GroupValueFunction() {
public Object getGroupValue(Object value, ListGridRecord record, ListGridField field, String fieldName, ListGrid grid) {
Date laDate = (Date)value;
if(laDate == null) {
return groupActual;
} else {
return groupClosed;
}
}
});
colonneDate.setGroupTitleRenderer(new GroupTitleRenderer() {
#Override
public String getGroupTitle(Object groupValue, GroupNode groupNode,
ListGridField field, String fieldName, ListGrid grid) {
final int groupType = (Integer) groupValue;
String baseTitle ="";
switch (groupType){
case groupActual:
baseTitle ="Actual Projects";
break;
case groupClosed:
baseTitle ="Closed Projects";
break;
}
return baseTitle;
}
});
listeGridProjets.setGroupByField("date");
I think you can sort your ListGrid on your colonneDate like this :
SortSpecifier sortSpecifier = new SortSpecifier("colonneDateFieldName", SortDirection.ASCENDING);
SortSpecifier[] sortSpecifiers = { sortSpecifier };
setSort(sortSpecifiers);

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'm a newbie in asp.net so I'm hoping you could give me some help on my dropdownlist bound to a table.
Here's the scenario:
I have a table Account with fields UserId, UserName and Type. The Type field contains 3 items: 'S', 'A', and 'U'. Each user has his own Type. I have a dropdownlist named 'ddlType' which is already
bound on the Account table. However, I want the options of the dropdownlist to be displayed as 'Stakeholder', 'Approver', and 'User' instead of displaying letters/initials only. Since I do not prefer making any changes in the database, how can I change those options through code behind?
Here's my code:
public void BindControls(int selectedUserId)
{
DataTable dtAccount = null;
try
{
dtAccount = LogBAL.GetAccountDetails(selectedUserId);
if (dtAccount.Rows.Count > 0)
{
lblUserId.Text = dtAccount.Rows[0]["UserId"].ToString();
txtUserName.Text = dtAccount.Rows[0]["UserName"].ToString();
ddlType.SelectedValue = dtAccount.Rows[0]["Type"].ToString();
}
}
catch (Exception ex)
{
throw ex;
}
finally
{
dtAccount.Dispose();
}
}
Any help from you guys will be appreciated. Thanks in advanced! :D
You can bind Dropdownlist in codebehind.
Get your data "Type" into array. Make array two dimentional and assign values to it.
After having data your array will looks like this,
string[,] Types = { { "Stakeholder", "S" }, { "Approver", "A" }, { "User", "U" } };
Now assign values to Dropdown,
int rows = Types.GetUpperBound(0);
int columns = Types.GetUpperBound(1);
ddlType.Items.Clear();
for (int currentRow = 0; currentRow <= rows; currentRow++)
{
ListItem li = new ListItem();
for (int currentColumn = 0; currentColumn <= columns; currentColumn++)
{
if (currentColumn == 0)
{
li.Text = Types[currentRow, currentColumn];
}
else
{
li.Value = Types[currentRow, currentColumn];
}
}
ddlType.Items.Add(li);
}
I haven't tested it but hopefully it will work.
I have several jqgrids running and all are functioning fine. However, when I do a search, I am only displaying ten search results per page. Whenever there are more than ten results, clicking on page two has no effect on the grid. Here is one of my controller actions, pay particular attention to the if satatement where search is true....
EDIT
I think I may have found a clue as to what may be causing my issue. You see I have several subgrids under the main grid. In terms of my java code I have object-A which has a list of object-B
, thus A has a subgrid of B. The way i am building up the json string to feed to the grid is by iterating over the list of B contained in A. I did not write a query of some kind to say order by, and limit the results etc.
So i guess the real question should be how to build a finder on a collection so that the contents can be arranged and ordered as i wish?
Here is the action I am calling for one of my entities described as B above. Pay particular attention to where i said person.getContacts()
#RequestMapping(value = "contactjsondata/{pId}", method = RequestMethod.GET)
public #ResponseBody String contactjsondata(#PathVariable("pId") Long personId, Model uiModel, HttpServletRequest httpServletRequest) {
Person person = Person.findPerson(personId);
String column = "id";
if(httpServletRequest.getParameter("sidx") != null){
column = httpServletRequest.getParameter("sidx");
}
String orderType = "DESC";
if(httpServletRequest.getParameter("sord") != null){
orderType = httpServletRequest.getParameter("sord").toUpperCase();
}
int page = 1;
if(Integer.parseInt(httpServletRequest.getParameter("page")) >= 1){
page = Integer.parseInt(httpServletRequest.getParameter("page"));
}
int limitAmount = 10;
int limitStart = limitAmount*page - limitAmount;
List<Contact> contacts = new ArrayList<Contact>(person.getContacts());
double tally = Math.ceil(contacts.size()/10.0d);
int totalPages = (int)tally;
int records = contacts.size();
StringBuilder sb = new StringBuilder();
sb.append("{\"page\":\"").append(page).append("\", \"records\":\"").append(records).append("\", \"total\":\"").append(totalPages).append("\", \"rows\":[");
boolean first = true;
for (Contact c: contacts) {
sb.append(first ? "" : ",");
if (first) {
first = false;
}
sb.append(String.format("{\"id\":\"%s\", \"cell\":[\"%s\", \"%s\", \"%s\"]}",c.getId(), c.getId(), c.getContactType().getName() ,c.getContactValue()));
}
sb.append("]}");
return sb.toString();
}
To fix the issue with pagination you need to replace the following block of code
for (Contact c: contacts) {
sb.append(first ? "" : ",");
if (first) {
first = false;
}
sb.append(String.format("{\"id\":\"%s\", \"cell\":[\"%s\", \"%s\", \"%s\"]}",c.getId(), c.getId(), c.getContactType().getName() ,c.getContactValue()));
}
with:
for (int i=limitStart; i<Math.min(records, limitStart+limitAmount); i++){
Contact c = contacts[i];
sb.append(first ? "" : ",");
if (first) {
first = false;
}
sb.append(String.format("{\"id\":\"%s\", \"cell\":[\"%s\", \"%s\", \"%s\"]}",c.getId(), c.getId(), c.getContactType().getName() ,c.getContactValue()));
}
Another option is using loadonce:true to let the jqGrid handle pagination and sorting. In this case you don't need to make changes described above
i have a single textbox named Keywords.
User can enter multiple strings for search.
How this is possible in mvc3?
I am using nhibernate as ORM.
Can i create criteria for this?
Edited Scenario
I have partial view to search job based on following values:
Keywords(multiple strings), Industry(cascading dropdown with functional area )//working well ,FunctionalArea//working well
Loaction(multiple locations), Experience//working well
In Controller i am retrieving these values from form collection.
What datatype should i use for keywords and location (string or string[] )?
public ActionResult SearchResult(FormCollection formCollection)
{
IList<Jobs> JobsSearchResultList = new List<Jobs>();
//string[] keywords = null;
string location = null;
int? industry = 0;
int? functionaArea = 0;
int? experience = 0;
string keywords = null;
if (formCollection["txtKeyword"] != "")
{
keywords = formCollection["txtKeyword"];
}
//if (formCollection["txtKeyword"] != "")
//{
// keywordAry = formCollection["txtKeyword"].Split(' ');
// foreach (string keyword in keywordAry)
// {
// string value = keyword;
// }
//}
......retrieving other values from formcollection
....
//Now passing these values to Service method where i have criteria for job search
JobsSearchResultList = oEasyJobsService.GetJobsOnSearchExists(keywords,industry,functionaArea,location,experience);
return View(JobsSearchResultList);
}
In Services i have done like:
public IList<EASYJobs> GetJobsOnSearchExists(string keywords, int? industryId, int? functionalAreaId, string location, int? experience)
{
IList<JobLocation> locationlist = new List<JobLocation>();
IList<Jobs> JobsList = null;
var disjunction = Expression.Disjunction();
ICriteria query = session.CreateCriteria(typeof(Jobs), "EJobs");
if (keywords != null)
{
foreach (string keyword in keywords)
{
string pattern = String.Format("%{0}%", keyword);
disjunction
.Add(Restrictions.InsensitiveLike("Jobs.keywords", pattern,MatchMode.Anywhere))
.Add(Restrictions.InsensitiveLike("YJobs.PostTitle",pattern,MatchMode.Anywhere));
}
query.Add(disjunction)
.Add(Expression.Eq("EASYJobs.Industry.IndustryId", industryId))
.Add(Expression.Eq("Jobs.FunctionalArea.FunctionalAreaId", functionalAreaId))
.Add(Expression.Eq("Jobs.RequiredExperience", experience)));
}
else
{..
}
JobsList = criteria.List<Jobs>();
}
Problems i am facing are:
In controller if i use string[],then Split(',') does not split the string with specified separator.It passes string as it is to Service.
2.In services i am trying to replace string with %{0}% ,strings with spaces are replaced/concat() here with given delimeter.
But the problem here is It always return the whole job list means not giving the required output.
Pleas help ...
As long as you have a delimiter you can break the input into pieces on you should be able to create an or expression with the parts. You can use a disjunction to combine an arbitrary number of criteria using OR's.
var criteria = session.CreateCriteria<TestObject>();
Junction disjunction = Restrictions.Disjunction();
var input = "key words";
foreach (var keyword in input.Split(" "))
{
ICriterion criterion = Restrictions.Eq("PropertyName", keyword);
disjunction.Add(criterion);
}
criteria.Add(disjunction);
Multiple keywords with special characters or extra spaces are replaced with single space with Regex expressions.
And then keywords are separated with Split("").
Its working as required....
if (!string.IsNullOrEmpty(keywords))
{
keywords = keywords.Trim();
keywords = System.Text.RegularExpressions.Regex.Replace(keywords, #"[^0-9a-zA-Z\._\s]", " ");
keywords = System.Text.RegularExpressions.Regex.Replace(keywords, #"[\s]+", " ");
if (keywords.IndexOf(" ") > 0)
{
string[] arr = keywords.Split(" ".ToCharArray());
for (int i = 0; i < arr.Length; i++)
{
if (!string.IsNullOrEmpty(arr[i]))
{
criteria.Add(Restrictions.Disjunction()
.Add(Expression.Like("EASYJobs.keywords", arr[i], MatchMode.Anywhere)));
}
}
}
else
{
criteria.Add(Restrictions.Disjunction()
.Add(Expression.Like("EASYJobs.keywords", keywords, MatchMode.Anywhere)));
}
}
While looking though some code of the project I'm working on, I've come across a pretty hefty method which does
the following:
public string DataField(int id, string fieldName)
{
var data = _dataRepository.Find(id);
if (data != null)
{
if (data.A == null)
{
data.A = fieldName;
_dataRepository.InsertOrUpdate(data);
return "A";
}
if (data.B == null)
{
data.B = fieldName;
_dataRepository.InsertOrUpdate(data);
return "B";
}
// keep going data.C through data.Z doing the exact same code
}
}
Obviously having 26 if statements just to determine if a property is null and then to update that property and do a database call is
probably very naive in implementation. What would be a better way of doing this unit of work?
Thankfully C# is able to inspect and assign class members dynamically, so one option would be to create a map list and iterate over that.
public string DataField(int id, string fieldName)
{
var data = _dataRepository.Find(id);
List<string> props = new List<string>();
props.Add("A");
props.Add("B");
props.Add("C");
if (data != null)
{
Type t = typeof(data).GetType();
foreach (String entry in props) {
PropertyInfo pi = t.GetProperty(entry);
if (pi.GetValue(data) == null) {
pi.SetValue(data, fieldName);
_dataRepository.InsertOrUpdate(data);
return entry;
}
}
}
}
You could just loop through all the character from 'A' to 'Z'. It gets difficult because you want to access an attribute of your 'data' object with the corresponding name, but that should (as far as I know) be possible through the C# reflection functionality.
While you get rid of the consecutive if-statements this still won't make your code nice :P
there is a fancy linq solution for your problem using reflection:
but as it was said before: your datastructure is not very well thought through
public String DataField(int id, string fieldName)
{
var data = new { Z = "test", B="asd"};
Type p = data.GetType();
var value = (from System.Reflection.PropertyInfo fi
in p.GetProperties().OrderBy((fi) => fi.Name)
where fi.Name.Length == 1 && fi.GetValue(data, null) != null
select fi.Name).FirstOrDefault();
return value;
}
ta taaaaaaaaa
like that you get the property but the update is not yet done.
var data = _dataRepository.Find(id);
If possible, you should use another DataType without those 26 properties. That new DataType should have 1 property and the Find method should return an instance of that new DataType; then, you could get rid of the 26 if in a more natural way.
To return "A", "B" ... "Z", you could use this:
return (char)65; //In this example this si an "A"
And work with some transformation from data.Value to a number between 65 and 90 (A to Z).
Since you always set the lowest alphabet field first and return, you can use an additional field in your class that tracks the first available field. For example, this can be an integer lowest_alphabet_unset and you'd update it whenever you set data.{X}:
Init:
lowest_alphabet_unset = 0;
In DataField:
lowest_alphabet_unset ++;
switch (lowest_alphabet_unset) {
case 1:
/* A is free */
/* do something */
return 'A';
[...]
case 7:
/* A through F taken */
data.G = fieldName;
_dataRepository.InsertOrUpdate(data);
return 'G';
[...]
}
N.B. -- do not use, if data is object rather that structure.
what comes to my mind is that, if A-Z are all same type, then you could theoretically access memory directly to check for non null values.
start = &data;
for (i = 0; i < 26; i++){
if ((typeof_elem) *(start + sizeof(elem)*i) != null){
*(start + sizeof(elem)*i) = fieldName;
return (char) (65 + i);
}
}
not tested but to give an idea ;)
