I use EditForm template in the RadGrid.
In the 

protected void RadGrid1_ItemCommand(object source, GridCommandEventArgs e)  
{   
 
}  
 
I can use the following codes to refer a control in Insert Form: 
 
GridEditableItem insertItem = e.Item.OwnerTableView.GetInsertItem();   
 
ListBox ListBoxA = (ListBox)insertItem.FindControl("ListBox1");  
 
 

How can I do the same thing for the Edit Form?

"GridEditableItem insertItem = e.Item.OwnerTableView.GetInsertItem(); " doesn't work for the  Edit Form.  I got the error message "Insert item is available only when grid is in insert mode."

Please help.

Hi,

Try accessing the controls in the editform in the edit mode as shown below.

CS:
 protected void RadGrid1_ItemCommand(object source, GridCommandEventArgs e) 
    { 
        if (e.CommandName == "Update") 
        { 
            GridEditableItem edititem = (GridEditableItem)e.Item; 
            ListBox txtbx = (ListBox)edititem.FindControl("ListBox1"); 
        } 
    } 


Thanks

Thanks Shinu for your quick response!

The solution you gave doesn't work. The txtbx returns value "null".

Anything else I can try?
