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

Tabs not working correctly

I have a winform with 2 radpageviews and controls on each. I have set the ones I don't care about to 0 and those I care about to tabindexes of 5 each (i.e. 5, 10 etc.)

They seem to go all over and not in the order I have it. See attachment. Left side is a pageview and the one in the middle is as well. Each of the tabs on the left use the same user control (date, processes, first shift etc).

CopyingCellClipboardContent

Hello,

I am trying to copy only the selected cell content but having FullRow selection mode. So I wanted to use the CopyingCellClipboardContent event but it does not fire with the Control+C Key combination. Is this the expected behavior?

So I have to use the KeyDown event from Gridview as this:

Private Sub grdMaquina_KeyDown(sender As Object, e As KeyEventArgs) Handles grdMaquina.KeyDown

If e.KeyCode = Keys.C And e.Control Then
If Not IsNothing(grdMaquina.CurrentCell) AndAlso Not IsNothing(grdMaquina.CurrentCell.Value) Then Clipboard.SetText(grdMaquina.CurrentCell.Value)
e.Handled = True
End If

End Sub

Is this correct?

Thank you.
