I have a simple project that uses a popup button to select a folder.

When opened via the pop up the control displays, but doesn't scroll to the selected item.

Any help making this happen would be appreciated.

See project here.

Thanks for the sample.  I believe the problem is that you might be setting SelectedDirectory too early, before shell data has loaded.  Then it fails to find anything and the control ends up selecting the first item as it loads, which replaces your SelectedDirectory value.  

If you remove all the popup event handlers and do this instead, it seems to work:

this.Dispatcher.BeginInvoke(DispatcherPriority.Loaded, (Action)(() => {
	SelectedDirectory = @"C:\Games";
}));
