Message Box in ASP

[Randy]

Hello,
I'm trying to figure out how to set up and call a javascript pop up window
within C# ASP. I know how to use RegisterStartupScript. This works fine if I
use it in the Page_Load area. What I want to do is call a pop-up window from
several areas in my class.
For example, I've got a Submit button but based on several conditions I
might want to pop up a message with the message varying. If I put the
RegisterStartupScript in this Submit_Click function, it doesn't pop up
anything.
I'm thinking I need to register a javascript popup function and then call
the function where I need to, but I don't know how to do this.
Can someone point me in the right direction?

Thanks

Here are some free MessageBox controls you can use to simplify things. The

It is similar to RegisterStartupScript...

Page.RegisterClientScriptBlock("alertblock", "<script
language='javascript'>function doalert() {alert('Hi there!'); return
true;}</script>")

And to call it from one of your buttons, add this:

Button1.Attributes.Add("onclick", "javascript:return doalert();")

Note that the return value will determine whether or not your page
posts back. So if you put return false in the function, you won't get
a postback, but return true will let the button continue on with
whatever server-side functionality it has.

What if you want to call it from within a button click function, and put
different messages in it based on certain processing?
How would you call it like this?
