Hi Liu Pei-Sen,

You can access any column using its ColumnUniqueName property. Try the following code snippet to access the ImageButton in the ItemTemplate of a GridTemplateColumn.

CS:

    
                protected void RadGrid1_ItemDataBound(object sender, Telerik.Web.UI.GridItemEventArgs e)  
        
                {  
        
                    if (e.Item is GridDataItem)  
        
                    {  
        
                        GridDataItem item = (GridDataItem)e.Item;  
        
                        ImageButton imgbtn = (ImageButton)item["TemplateColumn"].FindControl("ImageButton_Edit");  
        
                    }  
        
               }

Hope this helps..
Princy.
