NTreeList ChooseColumns popup and topmost form

Print Topic | Close Window

By Jeremy Courbat - 10 Years Ago

I probably found a bug.
In a TopMost From, I have a NTreeList. When I call the ChooseColumns method, the popup window appears but it goes behind the TopMost Form and because the popup is modal, nothing can be done, except kill the process.

So, Are there a way to open the ChooseColumns popup in a TopMost Form?

Thanks you in advance.
