SelectedRows

[Mauricio]

Hi, everyone,

I have been using telerik controls for windows for few months now, and this may be a stupid question. I've noticed that when a radgrid has been filtered or sorted, the SelectedRows property shows only one row selected even though more than one has been selected. I had a piece of code that uses that property so that on the edition of one row the value is copied to the other rows.

Here's a sample of my code:

Private Sub rgvContractDetails_CellEndEdit(sender As Object, e As Telerik.WinControls.UI.GridViewCellEventArgs) Handles rgvContractDetails.CellEndEdit
   Try

      If rgvContractDetails.SelectedRows.Count > 1 Then

         Select Case e.Column.Name
            Case "Quantity"
               For Each Row As GridViewRowInfo In rgvContractDetails.SelectedRows
                  Dim oSelectedItem As SalesContractDetail = Row.DataBoundItem
                  Row.Cells("Quantity").Value = e.Value
                  oSelectedItem.QuantityStr = e.Value
                  oSelectedItem.CalculateBalance()
                  Row.Cells("QtyBalance").Value = oSelectedItem.BalanceStr
               Next
            Case "QtyCancel"
               For Each Row As GridViewRowInfo In rgvContractDetails.SelectedRows
                  Dim oSelectedItem As SalesContractDetail = Row.DataBoundItem
                  Row.Cells("QtyCancel").Value = e.Value
                  oSelectedItem.CancelStr = e.Value
                  oSelectedItem.CalculateBalance()
                  Row.Cells("QtyBalance").Value = oSelectedItem.BalanceStr
                  Row.Cells("CancelDate").Value = Today.ToShortDateString
               Next
      End If

   Catch ex As Exception
      MessageBox.Show(ex.Message, "Error", MessageBoxButtons.OK, MessageBoxIcon.Error)
   End Try
End Sub

Is this the default behavior? If so, is there a workaround so that I can persist the selected rows programmatically and keep my code as it is?  I am using version 2011.02.712.

Thanks for your help,

Mauricio.

Hello Mauricio,

Thank you for your question.

I tested the scenario you describe and I confirm that RadGridView loses the multiple selected rows when it has a sorted column and a cell value is edited. I added this issue to our PITS and updated your Telerik points for reporting it. We will address the issue in a future release.

I was not able to reproduce the issue regarding the filtered RadGridView.

Thank you for your response. You are definitely right about the filtering issue, It was my mistake. I have no problem when filtering and I'm looking forward for your next release.

Thanks again!

Hello Mauricio,

I could suggest a workaround for the MultiSelect sorting issue - the selected rows are lost when RadGridView raises the CellEndEdit, event but not when the control raises the CellBeginEdit event. You can get the selected rows in a CellBeginEdit event handler and use them in the CellEndEdit event handler.

I hope it helps.
