Problems with GridViewCheckBoxColumn

[n/a]

Hi,

I've some problems with the GridView, If I add a GridViewCheckBoxColumn:

grdTestTools.Columns.Add("Id", "ToolId")
grdTestTools.Columns.Add("PositionNumber", "Pos.-Nr.")
grdTestTools.Columns.Add(New GridViewCheckBoxColumn("Versuch", "Test"))
grdTestTools.Columns.Add("ToolNumber", "Werkzeugnummer")
grdTestTools.Columns.Add("Manufacturer", "Hersteller")
grdTestTools.Columns.Add("Coating", "Beschichtung")
grdTestTools.Columns.Add("NumberOfAdaptors", "Schneiden")
grdTestTools.Columns.Add("ActualCumulativeAverageNumberOfPieces", "Standmenge Ist")
grdTestTools.Columns.Add("DebitCumulativeAverageNumberOfPieces", "Standmenge Soll")
grdTestTools.Columns.Add("ActualCumulativeToolingCosts", "Werkzeugekosten Ist")
grdTestTools.Columns.Add("DebitCumulativeToolingCosts", "Werkzeugekosten Soll")
grdTestTools.Columns.Add("CumulativeNumberOfTools", "Benutzte Werkzeuge")
grdTestTools.Columns.Add("CumulativeBrokenDieCounter", "davon gebrochen")

I set some colors in CellFormatting. Works fine, until I add the GridViewCheckBoxColumn. And now... well, see screenshots. The wrong colors changing after I clear and reinsert the GridView.

Private Sub grdTestTools_CellFormatting(ByVal sender As Object, ByVal e As Telerik.WinControls.UI.CellFormattingEventArgs) Handles grdTestTools.CellFormatting

        MyColumn = e.CellElement.ColumnInfo

 

        If MyColumn.Name = "ActualCumulativeAverageNumberOfPieces" Or MyColumn.Name = "ActualCumulativeToolingCosts" Then

            'Ist-Färbung

            e.CellElement.ForeColor = CoreFunctions.MyDefaultToolActualValuesFontColor

            e.CellElement.DrawFill = True

            e.CellElement.NumberOfColors = 1

            e.CellElement.BackColor = Color.FromArgb(123, 123, 123)

 

        ElseIf MyColumn.Name = "DebitCumulativeAverageNumberOfPieces" Or MyColumn.Name = "DebitCumulativeToolingCosts" Then

            'Soll-Färbung

            e.CellElement.ForeColor = CoreFunctions.MyDefaultToolDebitValuesFontColor

            e.CellElement.DrawFill = True

            e.CellElement.NumberOfColors = 1

            e.CellElement.BackColor = Color.FromArgb(123, 123, 123)

        End If

 

End Sub

We are using RadControls 2010.2.10.0914.

And ideas? Thanks!

I hide the first Column

MyGridView.Columns(0).IsVisible = False

 
If I skip this, the colors are perfect.

Hello Andreas,

Thank you for writing.

RadGridView uses virtualization for its cells and when you are setting a value to a cell element, you need to make sure that has the coresponsing Reset too. Examples and explanation are available in this article: http://www.telerik.com/help/winforms/gridview-cells-formatting-cells.html.
