Docking Expand/Collapse Animation Problem

[Kiril]

Hi Telerik Team,

I have made the following extension of the RadDocking control: I have added Expand/Collapse functionality that allows users to Show/Hide the content of each Pane (when it is collapsed - only the header is visible). This is available only when the Pane is in floating mode. I have achieved this by adding an DoubleAnimationto the ToolWindow, animating the FrameworkElement.Height property. Everything works great but there is annoing 'vibration' of the Pane while collapsing (while the height is decreasing). Can you help me to figure out why this is happening and how to avoid this issue?

If nesessary I can send you a project to see the issue by yourself.

Thanks,
Kiril

Hi again,

you can download the project with .sln file from this link - it is a .zip file:
http://dox.bg/files/dw?a=9d924d86cb

To repeat the problem - start the solution -> Make 'Pane 1' floating -> Click the '-' (Minimise) button.
Can you see the 'vibration' when collapsing? Thank you and I will be very happy if you help me with this annoing issue.

Hello Kiril,

Simply add

window.VerticalAlignment = VerticalAlignment.Top;
window.VerticalContentAlignment = VerticalAlignment.Top;

under window definition inside PerformClickAction and everything should work as expected.

I hope it helps.
