Capture Form Close Click Event (Red X)

Question

Hi Everyone,

Could you please help with a little problem. I have code a very simple Windows Form that closes the form. I want to capture an event where the user has instigated the close by clicking the Close Button (red x), rather than a close instigated by code.

The Closing event fires when both ways of closing the form is used, but I want to differentiate between the two ways and capture the click event of the Close Button.

Any ideas where I could find information on this?

Thanks,
Shai

Answer 1

Hi,

In the FormClosing event th FormClosingEventArg has a property tha's called CloseReason. This is very usefull becouse if you want the Form to stop closing if the closing reason was CloseReason.UserClosing you can do (FromClosingEventArg.Cancel = true ) then do something in your code and finally close the form programatically(or use another logic ). The FormClosedEventArg has the same CloseReason property but then you can't stop the Form from closing.

Hope this help.

Exactly what I am looking for, thanks Camilo :)

Answer 3

The problem with this is that both programmatic close and the Red X has the same CloeseReason. : Userclosing

So if I want to delay the close triggered by the user, do some cleanup and then do a form1.Close() I'll be stuck in an endless loop
