            RadGrid1.DataSource = myDataTable;

 protected void RadGrid1_UpdateCommand(object sender, GridCommandEventArgs e)
        {
            //Get the GridEditableItem of the RadGrid    
            GridEditableItem editedItem = e.Item as GridEditableItem;
            //Get the primary key value using the DataKeyValue.    
            string ID = editedItem.OwnerTableView.DataKeyValues[editedItem.ItemIndex]["ID"].ToString();
