Hello,

lastly, we have updated our old version of Telerik to the newest one. Now we have a problem with the RadRibbonGroups. 

When we minimize the mainwindow, the RibbonGroups collapse.

 like these.

But in the old version of Telerik when the mainwindow was to small, two scrollbuttons appeared

on the left and right side of the RibbonView.

Is there any opportunity to use these two buttons in the newest version without collapsing groups?

thank you

I bag your pardon. I'm in need of 2.5D Chart for BarSeries. I've tryed reproduce it as it done in your 2.5D_Chart example but as a result I get 'System.Windows.Markup.XamlParseException' in WpfXamlLoader.Load method because your 2.5D_Chart example is some dodgy. The exception snapshot you can see in 'Snapshot.PNG' file attached.

So, what do I need. I need Bar chart with 2._5D BarSeries with fixed color (green color, for example, or magneta...it doesn't matter).

Below is XAML of single Bar Chart. In my application I have 8 instances of such Bar Charts. All of them changing in real-time.

I have an MVVM view where I am overriding a GridViewDataColumn.CellStylewith a DataTrigger style that changes the colour of the Background based on the cell value (0 is red, >0 is green). This works great, except any cells that have been coloured this way no longer show their horizontal gridlines. The gridlines are still visible on other cells in the same row, and all vertical gridlines are still visible, but no horizontal gridlines on the custom styled cells.

Any idea what would cause the horizontal gridlines not to display just because the Background colour is overridden??

See attached image for an example of the grid with this styling in place.

Hi,

Can we access the RadOutlookBar using keyboard shortcuts like RadRibbonView KeyTipService.AccessText. Also can we use arrow keys to navigate and select the items  in the RadOutlookBar.

Thanks

i am facing binding issues on RadCartesianChart LabelDefinitions .Please see the source and suggest me some ideas to rectify this problem

I like to get the Tool panes in my MVVM docking scenario hidden if the user clicks th close button of the RadPane.

The default processing seems to close and remove the pane. I cannot get the pane shown again by setting the IsHidden property to false (discussed in some other threads).

Setting the CanUserClose property of the pane to false hides the close button completely.

Is there a way to either

- modify the behavior of the close button (hide the pane instead of closing it)   or

- put an additional button to the panes header, that lets me exceute my desired operations.

Thanks and Regards

Good afternoon. How can I save the geometry of the selected objects to RadDiagram in xaml file? Now I take the RadDiagramShape geometry, convert it to a string and written in the xaml file. But when I try the reverse conversion, an error is thrown

1) the RadDiagramShape declare

<telerik:RadDiagramShape x:Name="ConditionShape"
 IsEditable="False"
AllowCopy="False" AllowCut="False" AllowDelete="False" AllowDrop="False" AllowPaste="True" Background="Azure" 
Geometry="{telerik:CommonShape ShapeType=RectangleShape }" StrokeThickness="1" Height="100" Width="100" RenderTransformOrigin="0.5,0.5" Position="180,50"/>

2) the entry in the xaml file

Init.overview.LibraryItems.FunctionItem[end].Data = Convert.ToString(ShapeFactory.GetShapeGeometry(FlowChartShapeType.DecisionShape));
 FunctionLibrary Done = new FunctionLibrary();
            Done = Init.overview;
            XmlSerializer xml = new XmlSerializer(typeof(FunctionLibrary));
            file.Close();
            using (var fStream = new FileStream(path: "./****.xml", mode: FileMode.Create, access: FileAccess.Write, share: FileShare.ReadWrite))
            {
                xml.Serialize(fStream, Done);
                fStream.Close();
            }
3) the result in a file
      <Data>M56;0,5L111,5;37,5 56;74,5 0,5;37,5z</Data>

4)  and the inverse transform

var converter = new System.Windows.Media.GeometryConverter();
var data = (Geometry) converter.ConvertFromString(ListCode[i].Data);
ConditionShape.Geometry = data;

this line is not recognized as geometry. how to convert in the required format?
