ASP.NET Web Application Message Box

Question

In an asp.net windows forms application, in the C# code behind you can use:

MessageBox.Show("Here is my message"); 

Is there any equivalent in a asp.net web application? Can I call something from the C# code behind that will display a message box to the user?

Example usage of this: I have a button that loads a file in the code behind. When the file is loaded or if there is an error I would like to popup a message to the user stating the result.

Any ideas on this?

You want to use an Alert. Unfortunately it's not as nice as with windows forms.

ClientScript.RegisterStartupScript(this.GetType(), "myalert", "alert('" + myStringVariable + "');", true);
