TreeView in GridView

Question

Hi, I know there must be a way to do this, and perhaps someone has already done it. I googled like crazy but found nothing at all. Anyway, what I want to do is have a TreeView in the first column of a GridView using WPF, which can expand and collapse and that will show/hide the row it belongs to, pretty much something like this (the demo is for ASP.NET, I want to be able to do the same in WPF):

In our company we bought Infragistics controls, but it doesn't have a built in solution, we're trying to avoid spending a lot of time coding this solution.

Thank you!

Answer 1

Infragistics support similar scenario, see their overview - for WinTree control.

They can also do this for grids (see under Hierarchical display).

Answer 2

Perhaps you're not using the right search terms... IMO, what you're actually looking for is not a GridView with a TreeView inside it, but rather a TreeView with columns.

Here are a some samples of TreeViews with columns (often called TreeList or TreeListView) :
