Private Sub rgReceiptDTL_ItemCommand(sender As Object, e As GridCommandEventArgs) Handles rgReceiptDTL.ItemCommand

    If e.CommandName = RadGrid.DeleteCommandName Then

    End If
End Sub
Private Sub rgReceiptDTL_ItemDataBound(sender As Object, e As GridItemEventArgs) Handles rgReceiptDTL.ItemDataBound
    rgReceiptDTL.EditIndexes.Add(e.Item.ItemIndex)
    e.Item.Edit = True
End Sub

    If (rgReceiptDTL.EditItems.Count > 0) Then
        For Each item As GridDataItem In rgReceiptDTL.MasterTableView.Items
            item.Visible = False
        Next
    End If
End Sub
