Draw a button and do something when its clicked

[area91]

hey i just created a button via code and how do i set it up to respond when clicked?

[PT Exorcist]

Button button1 = new Button();
button1.Click += new System.Windows.Forms.Button();
this.Controls.Add(button1);

later...

private void button1_Click(object sender, System.EventArgs e)
{
}

PT,
Check your event handler hookup...You need to wire it up via a delegate.

[CornedBee]

Should be

Button button1 = new Button();
button1.Click += new EventHandler(this, button1_Click);
this.Controls.Add(button1);

Actually its this

Button button1 = new Button();
button1.Click += new EventHandler(this.button1_Click);
this.Controls.Add(button1);

[CornedBee]

Isn't the this added automatically?

[DevGrp]

Yeah, you made a mistake with the comma afte this. It should be this.button1_click

[PT Exorcist]

ops forgot that when i made copy past of some parts of the code...when putting all toguether i deleted the delegate i think..lol

[CornedBee]

Indeed. I thought you must pass the owner object seperatly.

Would this work?
Button button1 = new Button();
button1.Click += new EventHandler(button1_Click);
Controls.Add(button1);

[PT Exorcist]

whats the difference?

[CornedBee]

Not explicitly referencing this. I wonder why people always write
this.Controls.Add...
etc.

[PT Exorcist]

hehe because in the IDE a combobox appears and u only have to write the first letters then

[PT Exorcist]

and sometimes u dont remember well the names of the vars/methods

[CornedBee]

In this case instead of writing 'this.' simply hit Ctrl+Space. Brings up the same box.
