Let’s say I have a form. It has an “Exit” button with a click event that calls this.Close(). When the button is clicked, a FormClosing event is fired.
In this event, I want to be able to differentiate between the Exit button being clicked and user clicking the X button on the top right? I examined the sender argument and its always the form regardless of what I clicked. Similarly e.CloseReason is always UserClosing.
So short of having a variable that tracks this, is there a way to differentiate between the regular button and an X button?
P.S. I am on WiseJ 2.2.x
Hi Matthew,
actually my previous reply was wrong as I mixed ClientEvent with ClickEvent and misunderstood your question.
Seeing the sender always the form is because it´s always the form firing that event (.NET convention).
But, you can use the DialogResult property of the button. Clicking on the “X” to close the window always results in DialogResult = None.
If you assign a DialogResult value to the button property, you´ll see it in the FormClosing event.
Please find a simple sample attached that shows how it works.

Hi Matthew,
this.close() on the client (browser) is always considered a user event so it’s UserClosing.
Maybe you can add some custom property/flag that you trigger when your user clicks on the Exit button?
