I'm using Visual Studio 2010 and i'm developing a windows form. Right now I'm using a data grid view and i want to write some functions that would allow you to automaticlly edit the datagrid by just changing the text in the Datagrid view. Right now, I am able to get the actual value but I need the value of the column in order to use it as a parameter when i use ADO.net here's what my code looks like now
private void dgv_DataLookup_CellValueChanged(object sender, DataGridViewCellEventArgs e)
{
DialogResult dr;
dr = MessageBox.Show("Are you sure you want to edit this field?", "Edit Cell", MessageBoxButtons.YesNo);
if (dr == DialogResult.Yes)
{
DataGridViewCell editItemCell = dgv_DataLookup[dgv_DataLookup.CurrentCell.RowIndex, dgv_DataLookup.CurrentCell.ColumnIndex];
string editItem = editItemCell.Value.ToString();
}
}
this here gets me the value of the current cell that is currently selected. I tried doing something like this
DataGridViewColumns columnCells = dgv_DataLookup.CurrentCell.ColumnIndex.Value.ToString()... something that would represent this but actual code. thanks!
According to what I understand you want to edit the value within a field, you can choose the value in this way.
private void button2_Click(object sender, EventArgs e)
{
if (MessageBox.Show("Are you sure you want to edit this field?",Application.ProductName.ToString(),MessageBoxButtons.YesNo)== DialogResult.Yes)
{
string editItem = this.dataGridView1.Rows[this.dataGridView1.CurrentRow.Index].Cells["NameField"].Value.ToString();
}
}
Bye

I want to display data. I used AfterFieldChange method to display the data but it turns out the radio button doesn't change. I already insert the data customer table, the BAQ (Business Activity Query) also work just that the screen form doesn't work.
private void UD24_AfterFieldChange(object sender, DataColumnChangeEventArgs args)
{
// ** Argument Properties and Uses **
// args.Row["FieldName"]
// args.Column, args.ProposedValue, args.Row
// Add Event Handler Code
//EpiDataView edvUD24 = ((EpiDataView)(this.oTrans.EpiDataViews["UD24"]));
//System.Data.DataRow edvUD24Row = edvUD24.CurrentDataRow;
EpiDataView view = oTrans.EpiDataViews["UD24"] as EpiDataView;
switch (args.Column.ColumnName)
{
case "Character03":
DataTable tblcust=customer(args.Row["Character03"].ToString());
if(tblcust!=null && tblcust.Rows.Count>0)
{
string client = tblcust.Rows[0]["Customer_client1_c"].ToString();
view.dataView[view.Row]["ShortChar04"] = client;
//MessageBox.Show(Client);
}
break;
}
}
After changing the data in the EpiDataView you need to call Notify to make it call the UI elements that need to be updated:
view.dataView[view.Row]["ShortChar04"] = client;
view.Notify(new Ice.Lib.Framework.EpiNotifyArgs(this, view.Row, NotifyType.Initialize));
Kieym, perhaps try adding EpiNotifyArgs into your declaration, like so:
private void UD24_AfterFieldChange(object sender, DataColumnChangeEventArgs args, EpiNotifyArgs args)
Maybe this is to simple. If I have a textbox where I want to input a numeric value like "1300" and make it to display like datetime like this "13:00".
So what you should see is only 13:00 but it's also the days date.
anyone understand my question?
May be you need to use Day or Time Picker. This is most common way for Windows Phone to display date and time.
Check also Making a DateTimePicker
and Windows Phone 7 - DatePicker and TimePicker
But if you want to use only TextBox, you need to handled TextBox.LostFocus=OnLostFocus
private void OnLostFocus(object sender, RoutedEventArgs e)
{
//here change text of TextBox however you want.
}
UPD
If you want to place current time to TextBox as default value you can to use
tb.Text = DateTime.Now.ToShortTimeString();
when you arrive to current page or when TextBox.GotFocus=OnGotFocus
private void OnGotFocus(object sender, RoutedEventArgs e)
{
tb.Text = DateTime.Now.ToShortTimeString();
}
UPD2
When in TextBox you have value (for example 1300) you need to parse it and get newHours hours and newMinutes minutes. Then
var today = DateTime.Now;
var newDate = new DateTime(today.Year, today.Month, today.Day, newHours, newMinutes, 0);
I have one variable and this variable contain multiple data.
I want to find perticuler one data so how i can find it?
my code is like
private void g1_Hold(object sender, Microsoft.Phone.Controls.GestureEventArgs e)
{
var item=(sender as StackPanel).DataContext;
}
Here item contain multiple data like id, name ,imagepath,songpath etc.
Now i want just imagepath so how i can get it.
Help me .
Thanks in advance.
Try this one.
Hope its working if you store data in class.
private void g1_Hold(object sender, Microsoft.Phone.Controls.GestureEventArgs e)
{
StackPanel stk = (StackPanel)sender;
ClassName sg = (ClssName)stk.DataContext;
string path=sg.imagepath;
}
Its Quite easy store data into array or list than find position of data
For example
EDIT:
ListBox lst = (ListBox)sender;
classname obj = (classname)lst.SelectedItem;
now you can use obj.anything you want
I want to programmatically access the Fields collection in the ObjectDataSource object of my Telerik report.
I did notice in the design portion of the Telerik report you can access the fields collection
in the Value by using the Edit Expression window.
Example:
= Fields.MyFieldName
How would I accomplish this task using C# code in the report code behind file?
I had the same problem. This is how I solved it, although I believe there should be an easier way.
First I created a method for the details section itemdatabinding:
private void detail_ItemDataBinding(object sender, EventArgs e)
{
Telerik.Reporting.Processing.DetailSection section = (sender as Telerik.Reporting.Processing.DetailSection);
object id = section.DataObject["Data Field You want to access"];
Variable Name = id.ToString();
}
You can now use that variable anywhere in your codebehind.
Note: The Data Field must appear in your detail section. In my case I did not need it to show, so I just made 'Visible=false'.
This worked for me.
Bind Data to your own data to your variables
string ItemCode = "a";
string ItemDesc = "aa"
Then bind it to the data source
var Output = new
{
ItemCode = a.ItemCode,
ItemDesc = a.ItemDesc,
};
this.DataSource = Output;
All these are in code behind. Then move to design portion and modify your text-box as shown below.
= Fields.ItemCode
= Fields.ItemDesc
well the problem is that i am trying to get DDL to:
1. Recive catagories from a DB tabel - working
2. OnChange select from a different table the products by the item in the DDL - working
had a problem with No1 but fixed that problem. i found out that to get No1 working i have to use postback. did that and every thing in that part is working well and actualy every thing is working...but my hug problem (and i cant find any good answer for it) is that every time i change the item i a getting all the times all over again(i have initialy 8 item - secont time 16 - 24 etc....)
tried to use: ddlCatagories.Items.Clear();
when i use that i am not getting any duplicates but then, i am not getting any thing, it takes the first catagory from the list every time, no matter what i chose in the list..
trying to figure it out for the past week...please help :-)
public partial class selectNamesFromCatagories : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
ddlCatagories.Items.Clear();
SqlDataReader dr = DbHelper.ExecuteReader(
sqlConn1.home,
"spSelectNamesFromCatagories");
while (dr.Read())
{
ListItem li = new ListItem(dr["CategoryName"].ToString());
ddlCatagories.Items.Add(li);
}
dr.Close();
}
protected void ddlCatagories_SelectedIndexChanged(object sender, EventArgs e)
{
SqlDataReader dr = DbHelper.ExecuteReader(
sqlConn1.home,
"spProductsByCatagoryID",
new SqlParameter("#catName", ddlCatagories.Text)
);
while (dr.Read())
{
TableRow tr = new TableRow();
for (int i = 0; i < dr.FieldCount; i++)
{
TableCell td = new TableCell();
td.Text = dr[i].ToString();
tr.Controls.Add(td);
}
tblProductsByCatagories.Controls.Add(tr);
}
}
}
Only populate the DropDownList on first load by checking whether the page has not posted back ie.
if (!Page.IsPostBack)
{
// Populate list
}
I agree with Dan and would add the following as well if you have any ajax enabled controls as they may generate callbacks.
if (!Page.IsPostBack && !Page.IsCallBack)
{
// Populate list
}
