data source in detail table. i written code in itemdatabound event for mastertable view as follows

if ((e.Item is GridDataItem) && (e.Item.OwnerTableView.Name == "Detail"))
       {
            GridDataItem item = (GridDataItem)e.Item;
item.findcontrol("<control id of any detail table example radcombox id in detail table>")//returns null
      }
but this code wont work for me. i am not able to find  control over there.

Hello Ramakrishna,

Try the following code snippet in ItemDataBound to access the ComboBox in TemplateColumn.

C#:

protected void RadGrid2_ItemDataBound(object sender, GridItemEventArgs e)

{

        if (e.Item is GridDataItem && e.Item.OwnerTableView.Name == "Detail")

        {

            GridDataItem item = (GridDataItem)e.Item;           

            RadComboBox combo = (RadComboBox)item.FindControl("rdCmbBxAuxillarymeterdatatype");          

        }

}

Thanks,
Shinu.
