    I have a case where setting the IsHidden property to "false" expands the hidden pane, but does not draw the content.
    When I then toggle the IsHidden property to true and fals again, the content is displayed correctly!

    What can be the cause of this?

    Hi Lennart,

    How come when setting the IsHidden property to "false" the hidden pane is expanded, isn't it supposed to hide? Could you please prepare a simple example, in which the issue can be observed, open a support ticket and attach it there. In that way we will be able to resolve the issue in a timely manner.

    Looking forward to your reply.

    IsHidden = false  *** means the element is visible (not hidden)

    I'm having trouble with the IsHidden binding. If I have 2 or more RadPanes within a RadPaneGroup and have their IsHidden properties bound to a static class boolean property, only 1 of the panes hide when I toggle the property from false to true.

    All IsHidden bindings are working, there appears to be a bug when toggling the binding to more than one RadPane within a RadPaneGroup. 

    I'm using library 2013.1.220.40

    Hi Robert,

    Since you are binding to a static class, my concern is that the twoWay binding is not working correctly. Could you try to make the class a singleton class and expose a property that returns the singleton instance. That should make the TwoWay binding work.
    Also, would you be kind enough to send us a simple application which illustrates the issue, so that we can research it further and fix it in a timely manner.
