Webforms equivalent of a Message Box

[Tom Wild]

Hi

Is there an equivalent of the message box that can be used for webforms?
When I try to use a normal message box I get the following error:

"It is invalid to show a modal dialog or form when the application is not
running in UserInteractive mode. Specify the ServiceNotification or
DefaultDesktopOnly style to display a notification from a service
application."

Thanks

Execute a line of code like this when you want a message box to be
displayed.
(This writes out the necessary client side javascript to your HTML page to
make the alert pop up as soon as the page is sent to their browser.)

RegisterStartupScript("startupScript", "<script
language=JavaScript>alert('This is my message.');</script>");

This might come in handy for some folks. It's a MsgBox function I created
for ASP.Net apps to use:

/// <summary>
/// Adds a JavaScript "alert()" with strMessage to Page Startup
/// </summary>
/// <param name="strMessage">Message to display</param>
public static void MsgBox(string strMessage)
{
string s;
System.Web.UI.Page p;
try
{
if (HttpContext.Current == null) return;
s = "<script type=\"text/javascript\">" +
Environment.NewLine + "<!--" + Environment.NewLine +
"alert('" + strMessage.Replace("\"", "\\\"") + "');" +
Environment.NewLine + "// --></script>";
p = (System.Web.UI.Page) HttpContext.Current.Handler;
if (!(p.IsStartupScriptRegistered("MsgBox")))
p.RegisterStartupScript("MsgBox", s.ToString());
}
catch (Exception ex)
{
HandleError(ex); //Create your own Error Hander
}
}
