Answer 1

Have you enabled AutoPostBack property on your control?

By default this is set to False when you add a checkbox control to your page. Try setting it to true.

Answer 2

Set the Autopostback property to true.

chkCheckBox1.CheckedChanged += new EventHandler(chkCheckBox1_CheckedChanged);

You have to wire up this event on every call to the page so if you have put this inside of the if(!Page.IsPostBack) then put it outside.

Take a look at this article Adding a dynamic control to a placeholder control and wire up the event. It shows an extra step for making things totally dynamic but the principles stay the same for what you're after.

Answer 3

To trigger the following event

protected void chkCheckBox1_CheckedChanged(object sender, EventArgs e) { ..........
}

Set the checkbox autopostback property to TRUE
