[Solved] Radcombo in one column in radgrid

[Shweta]

Hi, 

I have a radgrid which i populate runtime using a dataset.
After that i need to add a radcombobox to every cell in one column of the radgrid.

For eg in the code below, for all cells in the "SECOND" column, i need a dropdown.
Can I get some help? Sample code will be very helpful

Dim tbl As DataTable = New DataTable
       tbl.Columns.Add("FIRST")
       tbl.Columns.Add("SECOND")
       Dim i As Integer
       For i = 0 To 4
           Dim row As DataRow = tbl.NewRow
           row.Item(0) = "ONE"
           row.Item(1) = "TWO"
           tbl.Rows.Add(row)
       Next
       RadGrid1.DataSource = tbl
       RadGrid1.Rebind()

Hello Shwetha,

Try the following code in ItemCreated event to add RadComboBox dynamically. Hope this helps you.

C#:

protected void RadGrid1_ItemCreated(object sender, GridItemEventArgs e)
{
 if (e.Item is GridDataItem)
 {
       GridDataItem item = (GridDataItem)e.Item;
   TableCell cell=item["ColumnUniqueName"];
       RadComboBox combo = new RadComboBox();
    combo.ID="combo";
    combo.DataSource=//set your datasource here
   cell.Controls.Add(combo);
    }
 }

Thanks,
Princy.

Thanks for the quick response Princy.
I tried your code, but it stops at



TableCell cell=item["ColumnUniqueName"];

It says
"Failed accessing GridColumn by index. Please verify that you have specified the structure of RadGrid correctly."
Sorry, I guess I am missing something very basic, since i am new to Asp.net as well as RadControls.

Thanks again,
Shweta

Thanks a ton.
Worked fine, only instead of itemcreated, i did it on itemdatabound. :)
One more question.
I want to add items (NOT using a datasource, but through code) to the combos added to this column.
Could you please help me?

Regards,
Shweta

Hi,

Got this too.
Another question about Radgrid, in the same context.
Before adding radcombos to all cells in one column, i want to get the value already existing in that cell.
How can i get it? in the itemdatatbound event itself? or in which event can i capture it?

Thanks,
Shweta

Hi,
How would you get the parent cell of RadComboBox in a OnClientDropDownClosedHandler?

This is is an ItemTemplate in a RadGrid
<telerik:RadComboBox ID="TerritoryManagerRadComboBox" runat="server" onclientdropdownclosed="OnClientDropDownClosedHandler">

 

function

 

 

OnClientDropDownClosedHandler(sender, eventArgs) {
  // here I want to get the cell object

 

 }

I need the cell object so that I change the style of the whole cell the RadComboBox is in. Or is there another way to do this?

Hi,

You can attach the OnClientDropDownClosed event from ItemCreated event ans can pass the Parent cell's ClientID as follows.

C#:

protected void RadGrid1_ItemCreated(object sender, GridItemEventArgs e)
{
    if(e.Item is GridDataItem)
    {
        GridDataItem ditem = (GridDataItem)e.Item;
        RadComboBox com = (RadComboBox)ditem.FindControl("TerritoryManagerRadComboBox");
        com.OnClientDropDownClosed = "function (button,args){OnClientDropDownClosedHandler('" + com.Parent.ClientID + "');}";
    }
}

Javascript:

<script type="text/javascript">
    function OnClientDropDownClosedHandler(id) {
        var parentcell = document.getElementById(id); //you can access the parent cell here
    }
</script>

Thanks,
Princy.
