Bertrand: I put a label inside the alert, passed the label to my utility, set label.text = 'error message string' and it worked perfectly. I feel a little dumb looking for long programatic solutions when like you pointed out the alert contents can be set up like any html page. Thank You for the help and the very usefull control.

@Sean: haven't touched that code in a while, but from the top of my head, the control uses its own contents as the text of the alert, so if you add a literal control to it with your message, it should work.

Bertrand I put this in my website and it works perfectly. I just have one problem that I am sure is my own lack of understanding. I have a central utility that carries out actions and posts various alerts if something goes wrong. The error message is passed as a string from server side code of the page to the server side code of the utility. I managed to get the utility to post the alert by using 'Imports Microsoft.Samples.Alert' but I can't find a way to get the error message string into the alert. There are many text options on the Alert Object like ServerAlert.Title or ServerAlert.OKText but there doesn't seem to be a ServerAlert.MessageText I noted in the html you have 'This is a rich alert box that was triggered by<br /><i>server-side code</i>' I am guessing that I can call a serverside proceedure between the <i>'s to supply text but I don't know the syntax or how.

@Alex: you forgot to copy the alert/displayalert.htm file to your site.

Added the Alert control to my project without issues, and it compiles fine, but when I trigger the .Show() method, the message box opens with an HTTP 404 in it, instead of the specified HTML.

I use Master Pages for my layout, if that makes any difference (downloaded it today from codeplex so I should have the latest version).

Any ideas?

How can I use the Alert.dll in VS2003, when I try to add a reference to it i get an error message saying

"A reference to XXX could not be added. This is not a valid assembly or COM component. Only assemblied with extension 'dll' and COM components can be referenced. Please make sure that the file is accesible and that it is a valid assembly or COM component"

Using .Net 1.1

The control in the Ajax Toolkit doesn't really use Ajax, so you might be able to reuse some of the code in there although it might be quite a lot of work. I guess your options would be to live with the status bar, make your own control using techniques similar to what the Toolkit is doing or use the toolkit.
