I have posted - How to use OpenFileDialog to select a folder?, I couldn\'t find the correct answer. So, I have changed my question.
I want to customize OpenFileDialo
You might not get a built in .Net control like that. Definitely the OpenFileDialog can not function as both File as well as Folder browser. You have two choices go for a third party tool like the one you found second make your own control. Surprisingly you might not find creating a very simple version of your own control very difficult.
