The problem is that you forgot the forward slash in the close script tag.
That causes the code to throw an error and not execute. You need to make
the last tag </script>.

news:YV***************@newssvr13.news.prodigy.com. .. Is it possible to pop-up a window from the code-behind
aspx.cs file on an OnClick event?
If so, how?
I've tried something like the following, but it doesnt seem to work.
private void MyButton_Click(object sender,
System.Web.UI.ImageClickEventArgs e)
{
Response.Write("<script>window.open('mypopUp_dialo g.aspx');<script>");
}
I don't want to use in-line javascript code or use a <script> tag within
my aspx file
itself.
