Question

I created a new form with buttons labeled as “OK” and “Cancel”
This form pops up by clicking a button from the first form. I’d like to run some code only if the “OK” button was clicked in the new custom form. This is not a MessageBox().

So far I have something like this:

CustomForm c = new CustomForm();
DialogResult r = c.DialogResult;

c.ShowDialog();

if (r == DialogResult.OK)
{
    //Run code
}

This however isn’t working. How do I code this properly? I also set the “OK” button as the AcceptButton in CustomForm.

Perhaps prefer compacting it like so:

CustomForm c = new CustomForm();

if (c.ShowDialog() == DialogResult.OK) {
    // run code
}

Also, remember you have to set the DialogResult of the button on the other form to be OK:

DialogResult is an enum. As such, it is copied by value.. not by reference.
