Grey out parents when filtering

Hi Dirk,

First, let me check... Have you seen our TreeListBox QuickStart named "Filtering with Captures"?  While it doesn't gray out non-matched ancestor items, it does show how matched items can have very visible highlights, drawing attention to them.  At the top of the sample, you can see a DataTemplate where the highlight foreground, background, and font weight can be set.  Will that work for your needs?

In sample browser application it says "the sample ..../MainControl" was unable to load. So I never realized what this sample was but after opening the sample files in windows explorer, yes this is exactly what I wanted..

Hi Dirk,

Thanks for reporting that, it looks like the classic non-SDK Sample Browser project we ship in the installer didn't have the TreeListBoxFilteringWithCaptures folder manually included.  We'll fix that for the next build.  If you open the project and Show All Files, you can manually include the folder, and then run the app project to see the sample in action.
