For this we can use Attributes
like
btn.Attributes.Add(“onclick”,“return alert()”);
btn–is the ID of the button on which u want this alert box
and u will be writing this Response.Redirect in button event only
and “btn.Attributes.Add(“onclick”,“return alert()”);”–this line in page init or page load

try this, load in Windows.Forms, use MessageBox.Show, that’s how i setup my Debug environment.

also you could add a custom control which contains


<script>alert('foo');</script>

or add it to a existing control like


this.label_a.attributes.add("onclick", "alert('foo');")

lots of other posibilities, enjoy

btw, dont use Response.write !!
