Extending the OpenFileDialog control with a picture preview... is it possible?

Hello,

I would like to extend the OpenFileDialog control in order to add an image preview box on the right side. I can't extend the OpenFileDialog as it is sealed. I think I could create my own by inheriting from FileDialog, but I have no clue where to start.

Has someone done this before? Is there a ready-made control available for purchase that does this already?

Examples of code are very much appreciated.


Thanks in advance,
Kosta

Windows allows it, but I don't know how to do it in .Net, sorry. But surely there is a way.
