C# + WPF + WrapPanel

If someone is familiar with WPF in C#, I'd love a bit of guidance here...

My goal: Create a gallery of thumbnails within a WrapPanel, given filePaths already defined in a ListBox's Collection.

I'm not really sure how the properties of the WrapPanel control work though, since it doesn't seem to have anything like a Source property. Does anyone know how I might be able to do this?

TL;DR /prog/ is full of self-entitled faggots



THREAD HIJACK:
how do I make sure a form control stays on top of another one? I have one that extends but it goes behind another instead of on top of it.
