Hello Pichet,

Try the following code snippet to access DropDownCOlumn.
C#:

protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)
{
//accessing dropdowncolumn in normal mode
 if (e.Item is GridDataItem)
  {
   GridDataItem itm = (GridDataItem)e.Item;
   string comboValue = itm["DestinationCountryCode"].Text;
  }
}
//accessing dropdowncolumn in edit mode
 if (e.Item is GridEditableItem && e.Item.IsInEditMode)
 {
   GridEditableItem itm = (GridEditableItem)e.Item;
   RadComboBox cmb = (RadComboBox)itm["DestinationCountryCode"].Controls[0];
 }
}

Thanks,
Princy.
