Description

How to display relations over event containers.

Solution

To have the relations appear over the GanttView tasks, you need to set the ZIndexManager.ZIndex attached property of the RelationContainer to a value larger than 40.

XAML

	<!-- If you're using the NoXaml binaries, you need to also add the following attribute to the style:
	BasedOn="{StaticResource RelationContainerStyle}" -->
	<Style TargetType="telerik:RelationContainer">
		<Setter Property="telerik:ZIndexManager.ZIndex" Value="50"/>
					<!-- ... -->
	</Style>
