RadComboBox ItemsRequested in EditItemTemplate

[James Kennon]

Hi,

I am using a RadComboBox in an EditItemTemplate of a GridTemplateColumn (in a Detail Table). How do I wire it to use the ItemsRequested event? I have tried wiring it in the RadGrid ItemDataBound event but the ItemsRequested event is never fired. I have set the  EnableLoadOnDemand property to true. I am using RadGrid 5.1.1.0 .

Regards,

James

RadComboBox combo2 = (RadComboBox)e.Item.FindControl("RadComboBox2");

            combo2.ItemsRequested += this.list_ItemsRequested;

RadComboBox combo2 = (RadComboBox)e.Item.FindControl("RadComboBox2");

            combo2.ItemsRequested += this.list_ItemsRequested;

Hello James,

Try to attach ItemRequested event to RadComboBox in ItemCreated event of RadGrid .

ASPX:

<DetailTables>
  <telerik:GridTableView Name="GridTableView1" runat="server">
     <Columns>
       <telerik:GridTemplateColumn>
         <EditItemTemplate>
           <telerik:RadComboBox ID="RadComboBox1"  runat="server"></telerik:RadComboBox>
          </EditItemTemplate>
        </telerik:GridTemplateColumn>
     </Columns>
     . . . . . . . .
 </DetailTables>

C#:

protected void RadGrid1_ItemCreated(object sender, GridItemEventArgs e)
   {
      if (e.Item is GridEditFormItem && e.Item.IsInEditMode && e.Item.OwnerTableView.Name == "GridTableView1")
          // check with Name of DetailTable
       {
           GridEditFormItem editItem = (GridEditFormItem)e.Item;
           RadComboBox combo = (RadComboBox)editItem.FindControl("RadComboBox1");
           combo.EnableLoadOnDemand = true;
           combo.AutoPostBack = true;
           combo.ItemsRequested += new RadComboBoxItemsRequestedEventHandler(combo_ItemsRequested);
       }
   }
 protected void combo_ItemsRequested(object o, RadComboBoxItemsRequestedEventArgs e)
    {

    }

Thanks,
Princy.

Hi,

Sorry,I probably should have mentioned that I am doing "InPlace" editing for the grid.  There is never any item returned to RadGrid1_ItemCreated that IsInEditMode is true for or with the correct OwnerTableView name and of course no EditFormItem.

Regards,

Ian

Hello James,

If you are using 'InPlace' EditMode for DetailTable , make the following changes in the above code.

C#:

protected void RadGrid1_ItemCreated(object sender, GridItemEventArgs e)
   {
       if (e.Item is GridEditableItem && e.Item.IsInEditMode && e.Item.OwnerTableView.Name == "GridTableView1")
       {
           GridEditableItem editItem = (GridEditableItem)e.Item;
           RadComboBox combo = (RadComboBox)editItem.FindControl("RadComboBox1");
           combo.EnableLoadOnDemand = true;
           combo.AutoPostBack = true;
           combo.ItemsRequested += new RadComboBoxItemsRequestedEventHandler(combo_ItemsRequested);

       }
   }

Thanks,
Princy.
