Trying to access an <asp:dropdownlist> from <telerik:GridTemplateColumn> in the ItemCommand event of a RadGrid. 

 

 

BarID is the unique column name on the template column
ddlBarID is the id of the dropdownload

GridEditFormItem editedItem = (GridEditFormItem)((GridDataItem)e.Item).EditFormItem;
DropDownList ddlBar = 
(DropDownList)editedItem["BarID"].FindControl("ddlBarID");
Label1.Text = "BarID null: " + (ddlBar == null).ToString();
ddlBar.Items.Add("TEST");

 

 

I get Object reference not set to an instance of an object.


any help is appreciated.  been banging my head on this one for two days now.

Hello,

Here is the sample that I tried which worked as expected.
C#:
protected void RadGrid1_ItemCommand(object sender, Telerik.Web.UI.GridCommandEventArgs e)
{
 if (e.CommandName == "commandname")
 {
   GridEditableItem editedItem = (GridEditableItem)e.Item;
   DropDownList ddl = (DropDownList)((Telerik.Web.UI.GridDataItem)(editedItem)).EditFormItem.FindControl("DropDownList1");
 }
}

Thanks,
Shinu.
