Well, my solution to this will be :

In FormClosing event, I'll get the 'e.CloseReason' and if it is 'CloseReason.UserClosing' which means user pressed 'X' button on top left corner of the form, I'll do my desired actions, and then, if I want, I'll let the form close, and if dont want to, I can prevent it from closing by setting 'e.Cancel' true.

Here is the code :

private void form1_FormClosing(object sender, FormClosingEventArgs e)
{
if (e.CloseReason == CloseReason.UserClosing)
{
//Do what you want
//e.Cancel = true; //-> this will prevent form closing.
}
}
