Customizing OpenFileDialog

by

Yes, that’s possible, I did the same kind of customization with SaveFileDialog successfully and it’s pretty interesting.

Follow the following links:

Also my own questions too will help you:

Change default arrangement of Save and Cancel buttons in SaveFileDialog

How to stop overwriteprompt when creating SaveFileDialog using GetSaveFileName

You have to use the WinAPI for this and you need to write the ShowDialog method in your own calling the GetOpenFileName windows function inside it, instead of calling .net’s OpenFileDialog. The GetOpenFileName will create the windows OpenFileDialog. (Refer to http://msdn.microsoft.com/en-us/library/ms646927%28v=vs.85%29.aspx). This together with writing the HookProc procedure and catching events such as WM_INITDIALOG, CDN_INITDONE inside it will help you do what you want.

To add radio buttons etc., you have to call the windows functions such as CreateWindowEx and SendMessage….

The 2nd link has the exact direction to the customization…

Ask for any clarifications…
