Hello Maher Khalil,

Attach ItemUpdated and ItemDeleted events to radgrid and check for 'e.Exception' which indicates whether exception occured during process.

CS:

    protected void RadGrid1_ItemUpdated(object source, GridUpdatedEventArgs e)
    {
        if (e.Exception != null)
        {
            e.ExceptionHandled = true;
            Response.Write(e.Exception.Message); // Show error message
        }
    }
    protected void RadGrid1_ItemDeleted(object source, GridDeletedEventArgs e)
    {
        if (e.Exception != null)
        {
            e.ExceptionHandled = true;
            Response.Write(e.Exception.Message); // Show message
        }
    }

Happy coding,
Shinu.

Hello Webster,

I guess you are performing data editing operations at database level with Update/Insert/Delete commands from the code-behind. In that case you can use the try-catch method directly inside the Update/Insert/Delete command for catching exception.

Also ItemUpdated/ItemInserted/ItemDeleted events fires only when an automatic update/insert/delete operation is executed.  Hope this information helps you.

Thanks,
Princy.

no im performing automaticdeletes

i have this codes:

    Private Sub DisplayMessage(ByVal text As String, ByVal grd As RadGrid)
        grd.Controls.Add(New LiteralControl(String.Format("<span style='color:red'>{0}</span>", "<br />" & text)))
    End Sub

    Private gridMessage As String = Nothing
    Protected Sub grdG_DataBound(ByVal sender As Object, ByVal e As EventArgs) Handles grdESCPagine.DataBound
        If Not String.IsNullOrEmpty(gridMessage) Then
            DisplayMessage(gridMessage, grdESCPagine)
        End If
    End Sub
    Private Sub SentMessage(ByVal text As String)
        gridMessage = text
    End Sub
    Protected Sub grdVal_ItemUpdated(ByVal source As Object, ByVal e As GridDeletedEventArgs) Handles grdESCPagine.ItemDeleted
        e.ExceptionHandled = True
        If e.Exception IsNot Nothing Then
            SentMessage("Error on Delete : " + e.Exception.Message)
        End If
        If TestoMessaggio.Length > 0 Then
            SentMessage("Error on Delete: " + TestoMessaggio)
        End If
    End Sub
