Close Form when not focused

alfie max15

I have a main form with a button, when pressed opens a second form. I want to make this form close when it is out of focused. I tried with a timer checking

private void IsFocused_Tick (object sender, EventArgs e)
{
if(!this.Focused)
{
this.DialogResult = DialogResult.Cancel;
}
}

But Nothing happens Can anyone tell me what i am doing wrong here?

there is no need to use a timer. there are events raised when a form loses focus - you probably want to handle the Deactivate event and close the form in that handler.

Wow... That worked like a charm... Thanks alot... M sorry but, i hadn't mentioned before, but there are two buttons on this second form, Which when clicked One opens the openfiledialog and the other folderbrowser. The problem is when i click any of the buttons it will bring up the Dialogs and so the form gets deactivated, as a result the dialog boxes also gets closed. :( Any way to work around this???

Create a flag that you set right before the dialog is shown and cleared when the dialog is dismissed. Check tge value of the flag in your event handler.

I think the codes should like this:

private void Form1_Deactivate(object sender, EventArgs e)
{
this.Hide();
}
