On VB.NET when you type in the element you can type 1/3/88 and it will automatically parse it to 1/3/1988. But on the C# it does not do that you have to type the whole date....

radmulticolumncombobox Line positioning on combo opening

Hello to all,
When I open the radmulticolumncombobox I would like to place it on the line that contains the text in the textbox.
Instead, it is placed on the first line.
Does anyone know where I am wrong?

Thanks a lot

Fabrizio

Click fires DoubleClick

Hi all,

there is a strange behaviour when clicking a GridView:

I have a GridView with some rows in. By DoubleClicking a row the DoubleClick Event is fired and a new form will be loaded.

Now I'm doing a click (single click!) and the RadGridView fires a DoubleClick Event again!

If the new form will open in front of the GridView the next click will NOT fire a DoubleClick Event.

If the form will open beside the Grid a DoubleClick will be fired...

Seems to me that there is a dependency whether the Grid has the Focus or not.

How to prevent the Click to fire a DoubleClick?

Change Series Color at Runtime

Hi we are evaluating telerik controls for use in our application.

Problem: The series won't change colors when the color is set at runtime.

Background:
I'm using ChartFX Winforms 2009 Q2

I am creating a solution where a chart is embedded in a Grid cell.
I use the grid.cellformatting event to set the grid image if the rowinfo tag has not been set, much like is suggested in the telerik sample for: Multiple child views with RadGridView for WinForms

To simplify the test, I just default the series bar value to: "series.Appearance.FillStyle.MainColor = Drawing.Color.Green " (see bulleted line in code block below)

Eventually I need to add a piece of code that will set the series color based on the value. For now I have just defaulted the value to show as green.

I have referenced other posts in the forum and added the lines to updategraphics, refresh, and still could not get the series to turn green.

Code:

    
                Private _chart As New RadChart

    
             Private Sub PrepareChart() 
        
                    Dim radChart As New GridToleranceChart 
        
                    Me._chart = radChart.chart 
        
                    Me._chart.SkinsOverrideStyles = False 
        
                End Sub

GridToleranceChart is a usercontrol that has a radchart on it. I use an instance of this usercontrol, and reference its public chart property, so I could set some visual elements at designtime. PrepareChart is called when the form loads.

    
            Private Sub grid_CellFormatting(ByVal sender As Object, _ 
        
                    ByVal e As CellFormattingEventArgs) _ 
        
                    Handles grid.CellFormatting 
        
                    Dim column As GridViewDataColumn = TryCast(e.CellElement.ColumnInfo, GridViewImageColumn) 
        
                    If column IsNot Nothing AndAlso StrComp(column.FieldName, _ 
        
                        Constants.DefaultToleranceColumnNames.TolPercentChart, CompareMethod.Text) = 0 Then 
        
                        If e.CellElement.RowInfo.Tag Is Nothing Then 
        
                            Me._chart.Series.Clear() 
        
                            column.Width = 300 
        
                            column.AllowResize = False 
        
                            e.CellElement.RowElement.RowInfo.Height = 60 
        
                            Dim series As New Telerik.Charting.ChartSeries() 
        
                         series.Appearance.FillStyle.MainColor = Drawing.Color.Green 

                            series.Type = Telerik.Charting.ChartSeriesType.Bar 
        
                            series.Name = "percentOfTolSeries" 
        
                            series.Appearance.LabelAppearance.Visible = False 
        
                            ' Get the value to add to the series from another cell in the same row of the cell that is being edited 
        
                            ' Add the value to the series 
        
                            Dim rowInfo As GridViewRowInfo = TryCast(e.CellElement.RowInfo, GridViewDataRowInfo) 
        
                            Dim value As Decimal = CDec(rowInfo.Cells(Constants.DefaultToleranceColumnNames.PercentOfTol).Value) 
        
                            series.Items.Add(New Telerik.Charting.ChartSeriesItem(value)) 
        
                            Me._chart.Series.Add(series) 
        
                            Me._chart.Refresh() 
        
                            Me._chart.Update() 
        
                            Me._chart.UpdateGraphics() 
        
                            e.CellElement.RowInfo.Tag = Me._chart.GetBitmap() 
        
                        End If 
        
                        e.CellElement.Image = TryCast(e.CellElement.RowInfo.Tag, System.Drawing.Image) 
        
                        e.CellElement.ImageLayout = ImageLayout.Center 
        
                        e.CellElement.DrawBorder = False 
        
                        e.CellElement.Text = "" 
        
                        e.CellElement.Padding = New Padding(0, 0, 0, 0) 
        
                    End If 
        
                End Sub

Your help is greatly appreciated.

Problem with RadDataFilter

Hello,

I have bound a GridView to a bindingsource. The bindingsource are based on the entity frame work and will be set with the following code:

bsDetekEingabePos.DataSource = (From DetektorPos As tblDetekEingabePos In

dbContext.tblDetekEingabePos                                                           Order By DetektorPos.Id Where DetektorPos.SN =

"4711" And

DetektorPos.VarianteNr = 1

Select DetektorPos).ToList

Now I have placed a DataFilter element on my form wich has the same datasource like the grid. I also have implemented the code:

Private Sub RadDataFilter1_Edited_1(sender As Object, e As TreeNodeEditedEventArgs) Handles RadDataFilter1.Edited RadDataFilter1.ApplyFilter()

End Sub

But when I select a filter in the DataFilter nothing happens. The grid shows the same data then before.
Do you have any idea what the problem can be?

Thank's in advance
Karim
