    I'm using a 3 column grid layout in my application. The left and right columns both include an expander with a RadOutlookBar in it.
    The center column loads different user controls depending on the context.

    Now I have a very weird problem with the expander on the right side:
    Whenever any(including DatePicker menues) tooltip in my application (no matter which usercontrol or gridcolumn) opens and IsExpanded is true, the whole expander "jumps" to the very left border of its parent grid.

    I also followed your guidelines regarding the expander and content alignment for smooth animations.

    Here is the markup of the expander:
    <telerik:RadExpander ExpandDirection="Left" IsExpanded="True" Grid.Column="1" Margin="0,0,0,5" x:Name="expanderCharts" animation:AnimationManager.IsAnimationEnabled="True" HorizontalAlignment="Right" VerticalAlignment="Stretch">
    Grid HorizontalAlignment="Left" VerticalAlignment="Stretch" Margin="3">

    Do you have any idea what could cause this behaviour?
    Thanks in advance.

    Hi Simon,

    Thank you for reporting the issue.

    We can not reproduce the issue with our latest releases. Attached you can find a test solution with an example built against the 3.09, 3.16 and 4.22 assemblies. Please try it and let us know if the issue appears at your side.

    Looking forward for your reply.

    PS: Long time ago there was a similar problem with the layout and tool-tips. However after the fix nobody complains. If you have an application with such symptoms please send it to us to investigate and fix it.

    Kind regards,
    the Telerik team

    Hi Ivan,

    Indeed I can't confirm the issue with your test solution. I guess the issue was caused by some other component interoperability.

    Meanwhile we migrated our solution to Silverlight 4 and the newest 422 telerik controls. After the upgrade the error seems to be gone in our solution as well. I did nothing but to upgrade from SL3 to SL4 and from telerik v309 to v422.

    Thank you for your help!
