RadWindow Top Animation

[mg]

Hello,

I am trying to animate the position of a RadWindow using a DataTrigger.

The following demonstrates what I am trying to achieve:

<telerik:RadWindow x:Class="TelerikRadWindow.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:telerik="http://schemas.telerik.com/2008/xaml/presentation"
        Height="350"
        Width="525"
        WindowStartupLocation="CenterScreen">
    <telerik:RadWindow.Style>
        <Style TargetType="telerik:RadWindow">
            <Style.Triggers>
                <DataTrigger Binding="{Binding ShouldMoveWindow}" Value="True">
                    <DataTrigger.EnterActions>
                        <BeginStoryboard>
                            <Storyboard>
                                <DoubleAnimation Storyboard.TargetProperty="(Window.Top)" To="+200" BeginTime="0:0:0" Duration="0:0:5" />
                            </Storyboard>
                        </BeginStoryboard>
                    </DataTrigger.EnterActions>
                </DataTrigger>
            </Style.Triggers>
        </Style>
    </telerik:RadWindow.Style>
</telerik:RadWindow>

namespace TelerikRadWindow
{
    public partial class MainWindow
    {
        public MainWindow()
        {
            InitializeComponent();
            ShouldMoveWindow = true;
            DataContext = this;
        }

        public bool ShouldMoveWindow { get; set; }
    }
}

When loaded, an exception is thrown:

This exact same sample works when using a Window rather than a RadWindow.

Does anybody have any idea why this is or what I can do to resolve it?

Many thanks.

Setting the target property to (telerik:RadWindow.Top) allows you to animate the window position.

[MobiusStrip]

For anyone else who comes here and wants to animate the position of the radWindow....

Note that you must also supply a Storyboard.TargetName.


So, in the <telerik.RadWindow section, supply a name
<telerik.RadWindow 
   x:Name="This"
   x:Class="...

and in the Storyboard point to "This" as the TargetName

<DoubleAnimation x:Name="MoveWIndowTop" Storyboard.TargetProperty="(telerik.RadWindow.Top)"
                              Storyboard.TargetName="This" To="100"...

(Giving the DoubleAnimation a x:Name value allows you to move the window around programatically in the code behind.)

    Me.MoveWindowTop.To = "500"
    Me.MoveWIndow.Begin()      

(That worked for me, somebody else may know how to avoid code behind to achieve the same, but without the TargetName I was crashing when I tried to fire the storyboard script.)
