Form inheritance

[purusingh1]

Suppose, I have a Form "Form1" and a button "btn1" on it in an application

on click event of btn1 I Wrote

MessageBox.Show(self.Name);



Now I inherite "Form2" from "Form1".

and on click event of btn1 I Wrote

MessageBox.Show("Hello");


Now when I press button of Form2 it fires both events.
How to restrict firing event of form1?

The click event is based on delegates - a list of method pointers. So, what's happening here, is you're attaching multiple event handlers to a single event - two messages displayed.

Top of my head [i.e. untested code]:

Form1:

private void btnClick(object sender, EventArgs e) {
	this.OnButtonClicked(sender, e);
}

protected virtual void OnButtonClicked(object sender, EventArgs e) {
	MessageBox.Show("Form 1");
}

Form2:

protected override void OnButtonClicked(object sender, EventArgs e) {
	MessageBox.Show("Form 1");
}
