Popup Suggestion

[C@rLoS]

Dear All,

I wanna ask how I can make up some pop-up message in ASP.NET WebForm. I cant
find anything like MessageBox in ASP.NET, and I have tried to use Javascript
(alert) to make it. It works fine ONLY IF the page will NOT be redirected to
another page afterwards. When Response.Redirect(, FALSE) is launched (even I
place a "false" there to indicate I want to finish all the script before
redirecting), before the Javascript alert may have popped up, the page is
redirected and I cannot see any alert. Is there any solution for my case?
Thanks.

Carlos

Hi Carlos,

You should understand that a web application is a client-
server mode, that is, your C# (or VB) code runs on server-
side, but javascript code runs on client-side. So when you
use alert(), it is in client-side. Unless after running
alert it posts back to server, it's impossible to run
Response.Redirect on server-side. Even if posts back to
server, you should also figure out it's after alert or on
other cases.

Here are some free MessageBox controls you can use to simplify things. The
source code is included in case you need to make any modifications:

Might be a good time to explore other programming methods than Trial and
Error.

First, this isn't a Windows Form. There is no MessageBox. You are correct,
however, that the JavaScript alert() function would pop up a Message Box of
sorts (the browser equivalent). But you apparently don't have ny
understanding of Response.Redirect. Response.Redirect appends a header to
the Response, indicating that the browser should request a different URL.
You may have noticed that when you use Response.Redirect, you never see the
first page at all. That is because, rather than displaying it, the browser
redirects. Since JavaScript is IN the page, it is never executed.

Knowing this, of course, the answer is obvious.
