I can't seem to find 3d chart demos either in the xaml sdk repository (https://github.com/telerik/xaml-sdk) or in the wpf demo application, is this feature no longer supported? I was trying to make a doughnut3d to work, but I get a StackTrace-less stackoverflow exception in runtime

.

Xaml:

 <telerik:RadChart x:Name="radChart" UseDefaultLayout="False" Height="300" ItemsSource="{Binding}"> <Grid Margin="10"> <Grid.RowDefinitions> <RowDefinition Height="Auto" /> <RowDefinition Height="*" /> </Grid.RowDefinitions> <Grid.ColumnDefinitions> <ColumnDefinition Width="*" />   </Grid.ColumnDefinitions> <telerik:ChartTitle Margin="0,0,0,10" HorizontalAlignment="Center" Content="Year 2008" Grid.Row="0" Grid.Column="0" /> <telerik:ChartArea x:Name="webBrowsersShare2008Chart" Grid.Row="1" Grid.Column="0" /> 

<!--<telerik:ChartTitle HorizontalAlignment="Center"<br>                                 Content="Year 2009"<br>                                 Margin="0,0,0,10"<br>                                   Grid.Row="0"<br>                                    Grid.Column="1" /><br>                <telerik:ChartArea x:Name="webBrowsersShare2009Chart"<br>                                  Grid.Row="1"<br>                                   Grid.Column="1" />-->

 </Grid> <telerik:RadChart.SeriesMappings> <telerik:SeriesMapping CollectionIndex="0"

<br>                                       ChartAreaName="webBrowsersShare2008Chart"><

<!--<telerik:SeriesMapping CollectionIndex="1"<br>                                      ChartAreaName="webBrowsersShare2009Chart"><br>                    <telerik:SeriesMapping.SeriesDefinition><br>                        <telerik:DoughnutSeriesDefinition /><br>                    </telerik:SeriesMapping.SeriesDefinition><br>                    <telerik:SeriesMapping.ItemMappings><br>                        <telerik:ItemMapping FieldName="Value"<br>                                            DataPointMember="YValue" /><br>                        <telerik:ItemMapping FieldName="Description"<br>                                           DataPointMember="Label" /><br>                    </telerik:SeriesMapping.ItemMappings><br>                </telerik:SeriesMapping>-->

Diagram Control Issue during Dragging

I have a diagram control, and I was drawing an arrow across it. I did this as ATP using Microsoft Coded UI. It recorded the sequence of steps correctly as well as the dragging, however, in the code behine it put this statement as a comment.

System parameter 'Show window contents while dragging' is not set.This could lead to incorrect recording of drag actions

when running the ATP, when it comes to the stage of drawing the arrow, it just does not, stays there as though nothing is happening. Any advice whats happening? The particular windows system parameter is set to show contents when dragging. using windows server 2008 R2.

Customizing RadAutoCompleteBox

Hi,

I am trying to customize the RadAutoCompleteBox visual to fit our application. I went thru the process of doing "Edit a Copy" of the Style. Without making any modification to the copied style, I've encountered an Error which causes the popup no longer shows up correctly.

System.Windows.Data Error: 4 : Cannot find source for binding with reference 'ElementName=WatermarkTextBox'. BindingExpression:Path=ActualWidth; DataItem=null; target element is 'AutoCompleteBoxesWrapPanel' (Name=''); target property is 'Width' (type 'Double')
