    Hello,

    I cannot found thread for Expander, so I get it here...

    I defined this:

    <StackPanel Grid.Column="1" Orientation="Vertical">
    <telerikPrimitives:RadExpanderControl>
    <telerikPrimitives:RadExpanderControl.ExpandableContent>
    <Grid>
    <telerikPrimitives:RadBusyIndicator AnimationStyle="AnimationStyle1" ...
    <telerikDataControls:RadListView>

    </telerikDataControls:RadListView>
    </Grid>
    </telerikPrimitives:RadExpanderControl.ExpandableContent>
    </telerikPrimitives:RadExpanderControl>
    <telerikPrimitives:RadExpanderControl x:Name="expanderSelectedAdvertisements"
    IsExpanded="True" IsExpandable="False">
    <telerikPrimitives:RadExpanderControl.ExpandableContent>
    <Grid>
    <telerikDataControls:RadListView x:Name="telerikListSelectedAdvertisements">
    </telerikDataControls:RadListView>
    </Grid>
    </telerikPrimitives:RadExpanderControl.ExpandableContent>
    </telerikPrimitives:RadExpanderControl>
    </StackPanel>

     

    When I start app, I get immediately this error:

    System.Runtime.InteropServices.COMException: No installed components were detected.
    Multiple animations in the same containing Storyboard cannot target the same property on a single element.
       at Windows.UI.Xaml.VisualStateManager.GoToState(Control control, String stateName, Boolean useTransitions)
       at Telerik.UI.Xaml.Controls.RadContentControl.SetVisualState(String state, Boolean animate)
       at Telerik.UI.Xaml.Controls.RadContentControl.UpdateVisualState(Boolean animate)
       at Telerik.UI.Xaml.Con

     

    Why? When I use Expander in other view and expandable content defined as ExpandableContentTemplate, all working right.
