I created a form and I want it to be modal, so users can't interact to what is behind this form. 

I've already tried to set "FormBorderStyle" to FixedDialog, but I still can interact with contents below this window.

Am I missing something?

Thanks!!

Hi André,

Thank you for writing.

The only thing that you have to do in order to show a form as a modal form is to call its ShowDialog method instead of the Show method:
Form1 f = new Form1();
f.ShowDialog();

I hope that you find this information helpful.

All the best,

That's the way I always understood it but that's not what's happening. Code execution does not wait for user response and returns a result of cancel even when there was no cancel button to click

Hello,Timothy,     

When you show a form with using ShowDialog the code execution is interrupted at this point until you close the modal dialog. Note that pressing the close button in the title bar, "X", will return DialogResult.Cancel. However, you have other button that simply closes the form you can specify what DialogResult will be returned. I have attached a sample project for your reference.

I hope this information helps. If you have any additional questions, please let me know. 

Regards,
Dess
