I have a Pie Chart that has a ChartSelectionBehavior.  This allows me to create another Bar series based on the information from the selected Pie Chart slice.  In the area of my Bar Chart, I have radio buttons and a grid view.  Clicking on the radio buttons or selecting a row in the grid view causes the ChartSelectionBehavior event of the pie chart to fire.  What is the setting that I need to configure to prevent the behavior?

Hi,

I am trying to create a loop - a link where source node and target node are the same node. I am able to create a loop from code, but it does not behave well. For example when I try to drag connection end from one connector to some other connector on the same node, the end of the link doesn't attach to the connector, it is left unattached when dropped.

When I try to create new loop by dragging from one connector to another connector on the same node, the node and it's connectors don't seem to be active and I cannot create a link this way.

Is there some support for loops in RadDiagram or do you have some suggestions how to achieve this behavior?

Hello,

When grouping by a DateTime property without selecting a step, the value is formatted as 'mm/dd/yyyy HH:mm:ss'. Is it possible to change the format to not show the Time part of the DateTime object?

I'm laying out a 3d surface from a heightmap.   I've got all the data in there, and the surface is showing beautifully.  Unfortunately, the Y-axis is now how I want it.   Your 3d Chart does not lay out coordinates as a 2d image might.   When I look at the surface from directly above it, I want it to basically look just like the 2d image that this heightmap was built from. 

 

That is, with  X-min on left, X-max on right, Z min far away and Z max closest to the eye,  then I want Y to increase from top to bottom.  Just as it would in any 2d image.  But your 3D chart reverses this.

I need to invert it but I cannot figure out how.  I tried merely inverting the Y data but that had no effect.  I could not find any sort of "IsInverse" property for the 3d chart axes. 

What is the best way to achieve what I want?

Is there any easy way -- like, perhaps, some equivalent ofthe old 2d chart's IsInverse property in the 3d world?

If not, is there some other way to achieve this?  I did find a similar question for the newer 2d chart:  ( https://www.telerik.com/forums/how-to-reverse-the-y-axis-values ).  I've downloaded it and am looking at it but it relies on events that I cannot find in the 3d world:  Like a "RangeChanged" event.  I'm not sure if I can adapt this to suit my needs.

I haven't seen any exampels of how to do this, though this one shows how to do it in the code behind (http://www.telerik.com/community/forums/wpf/gridview/sort-arrow.aspx).

In the documentation (http://www.telerik.com/help/silverlight/gridview-sorting-programmatic.html), it shows this:
<telerik:RadGridView x:Name="radGridView"
                        
AutoGenerateColumns="False">
   
<telerik:RadGridView.SortDescriptors>
       
<telerik:SortDescriptor Member="Title"
                                   
SortDirection="Ascending" />
   
</telerik:RadGridView.SortDescriptors>
   
...
</telerik:RadGridView>


However, Member is not a property on SortDescriptor.

I tried this instead:


        <telerik:ColumnSortDescriptor   SortDirection="Ascending"
                                                Column="{Binding ElementName=nextContactColumn}">
                </telerik:ColumnSortDescriptor>

And got the error: Object reference not set to an instance of an object.

How do I in XAML tell the RadGridView to sort by a column

I want to check the nth item of the ComboBox with CheckBox dynamically. How can this be achieved?

I tried the following and an exception is thrown

radCombo.Items(n).IsSelected = True

 

The XAML is as followed:

 <DataTemplate x:Key="CheckBoxItemTemplate">
            <CheckBox Content="{Binding RelativeSource={RelativeSource AncestorType=telerik:RadComboBoxItem}, Path=Content}" 
                      IsChecked="{Binding RelativeSource={RelativeSource AncestorType=telerik:RadComboBoxItem}, Path=IsSelected}" 
                      telerik:TouchManager.ShouldSuspendMousePromotion="True" Click="CheckBox_Click"/>
        </DataTemplate>

 

<telerik:RadComboBox Name="radCombo" Height="30" Canvas.Left="650" Canvas.Top="55" Width=" 200" Background="White" AllowMultipleSelection="True" EmptyText="Select "
                                         MultipleSelectionSeparator=","  IsReadOnly="True" ItemTemplate="{StaticResource CheckBoxItemTemplate}" >
                    </telerik:RadComboBox>
