Problem with cellformatting and horizontal scroll

[Blas]

Hello,

I have a grid with a status column in which I want to place a red o green ball depending the bound value. I've tried to do that with the next code:

Private Sub Grid_CellFormatting(ByVal sender As Object, ByVal e As Telerik.WinControls.UI.CellFormattingEventArgs) _

        Handles gridPedidos.CellFormatting, _

                gridChrono.CellFormatting, _

                gridCentros.CellFormatting, _

                gridIncidencias.CellFormatting, _

                gridIncidenciasPFR.CellFormatting, _

                gridPedidosWeb.CellFormatting

    e.CellElement.Image = Nothing

    Dim column As GridViewCommandColumn = TryCast(e.CellElement.ColumnInfo, GridViewCommandColumn)

    If column IsNot Nothing Then

        Select Case column.UniqueName

            Case "Txt"

                CType(e.CellElement.Children(0), RadButtonElement).Image = My.Resources.document_text

                CType(e.CellElement.Children(0), RadButtonElement).ImageAlignment = ImageLayout.Center

            Case "Datos"

                CType(e.CellElement.Children(0), RadButtonElement).Image = My.Resources.table_view

                CType(e.CellElement.Children(0), RadButtonElement).ImageAlignment = ImageLayout.Center

        End Select

    End If

    If e.CellElement.ColumnInfo.Name = "Status" AndAlso TypeOf e.CellElement.RowInfo Is GridViewDataRowInfo Then

        Dim Status As Integer = CInt(e.CellElement.RowInfo.Cells("Status").Value)

        If Status = 0 Then

            e.CellElement.Image = My.Resources.button_green

        Else

            e.CellElement.Image = My.Resources.button_red

        End If

        e.CellElement.Text = ""

    End If

End Sub

Executing the program the status column is draw right as you can see in the image1 attached. But scrolling horizontally right and left, the red and green balls are showed in other columns (image2)

Thanks in advance

Hello Roberto Andrade Olivie,

Thank you for contacting us. In our latest release we added column virtualization. This enables using large number of columns without a performance lost. Only the cells that are currently visible are created. When scrolling cells are reused and this causes the issue. 

To solve the issue you should create custom cell and column. Please send us your project and we will do the necessary modifications for you.

I am looking forward to your reply.

Kind regards,
Jack

Hi Jack,

Thank you very much for your response.

Finally I've discovered that what makes cell formatting works properly is e.CellElement.Image = Nothing at the begining of the CellFormating procedure, and I didn't put it, although in my initial post code was indicated.

Private Sub RadGridView1_CellFormatting(ByVal sender As Object, ByVal e As Telerik.WinControls.UI.CellFormattingEventArgs) Handles RadGridView1.CellFormatting
      e.CellElement.Image = Nothing
      If e.CellElement.ColumnInfo.Name = "CategoryID" AndAlso TypeOf e.CellElement.RowInfo Is GridViewDataRowInfo Then
          Dim CategoryID As Integer = CInt(e.CellElement.RowInfo.Cells("CategoryID").Value)
          If (CategoryID Mod 2) = 0 Then
              e.CellElement.Image = My.Resources.button_green
          Else
              e.CellElement.Image = My.Resources.button_red
          End If
          e.CellElement.Text = ""
      End If
  End Sub

Thank you for your help.
