File Dialog - Button enabled if Item selected

[Captain_Jack_T]

Hey guys

In my code i use a folderpicker and a user can press on the OK-Button, even if he did not select any item.
Does anyone know how i can handle this issue, like disable the button if not one item has been selected?

Thanks in advance!!

You would need to check the value for null and reopen the folderpicker. However, I don't believe this differentiates between a null OK or a cancel. I typically assign the "Application.DefaultFilePath" when the user doesn't select one.
