Solution 2

Code:[Convert to VB if required]

ScriptManager.RegisterStartupScript(this.Page, this.GetType(), "Alert", "<script type='text/javascript'>testmsg('This is the alert you want');</script>", false);

JavaScript:

C#

<script type="text/javascript">
    function testmsg(msg) {

       alert(msg);
    }
</script>
