what is this "nl "
it doesn't exist in class or namespace

Do a script callback and point to a javascript function that does:

<script type=text/javascript language=javascript>
function MessageBx()
{

Alert("Message to display);
}
</script>

You cannot use a messag box normally because asp is server side....it
will try to display the box on the server. Javascript is the easiest
way to accomplish this. It is client side and will display the box
with the "Alert()" method.

Response.Write("<script language=jscript>alert('" + "hello" +
"')</script>");

solved

Ah sorry. I created a static variable with a short name to substitute for
having to write Environment.NewLine with each new line:

private static string nl = Environment.NewLine;

You could use this free control to do it, or examine its free source code to
see how to do it yourself:

Hi Ankit,

Glad that you're got it working.

BTW, for registering client-side script, we're recommended to use the
Page.ClientScript.XXXX methods instead of Response.Write to do the work.
The page's encapsulated methods can help ensure the startup script or
script block be registered and output at the appropriate place.
