App freeze when behaviors are on a popup


When adding a behavior in a control in a popup, the app freeze because it can find the popup in the visual tree. I am gessing they are not in it. The code seems to loop in this method :

The output window keep showing endlessly : Popup Not in visual tree
private async void ConfigureDataContext()
  while (associatedObject != null)
    if (AssociatedObjectIsInVisualTree)
      Debug.WriteLine(associatedObject.Name + " found in visual tree");
          new Binding
            Path = new PropertyPath("DataContext"),
            Source = associatedObject

    Debug.WriteLine(associatedObject.Name + " Not in visual tree");
    await WaitForLayoutUpdateAsync();

Hi, I am aware of this problem but the problem with an AssociatedObject not being in the Visual Tree immediately bit me too but is fixed in changeset 18697 on Aug 17. Are you still having this problem? Have you tried the newest NuGet Package?

I installed the Library just a few days ago using NuGet and I have the problem. I will try by getting directly the Library for codeplex. But maybe you should check that the NuGet package is up to date then.

Same here, any news on that?

Guys, I have been looking into this today but it appears not to be that easy. I have a solution that does stop the app freezing, but then the data binding still does not work. If anyone has any suggestions, I'd be happy to implement them.

Resolved with changeset 24933: Popup apparently not found by VisualTreeHelper.GetParent. Checked if top parent's parent is a Popup
