Client side messagebox

[Probi]

Hello

I have a messagebox showing on the click of a button
it is a yes/no message box and so far it works in the localhost with MessageBox.Show

but when I publish the aspx page and run it on the server i get this error

"Showing a modal dialog box or form when the application is not running in UserInteractive mode is not a valid operation. Specify the ServiceNotification or DefaultDesktopOnly style to display a notification from a service application. "

can anyone give me pinters what to do?

thanks for any help

MessageBox.Show will not work for an ASP.NET page because it is a server side message box.

You need to use client side script to fire a message box. Try using the following function instead when you want to display an alert style messagebox:

Private Sub Message(ByVal sMessage As String)
    Dim myscript As String = "alert('" & sMessage & "');"
    Page.ClientScript.RegisterStartupScript(Me.GetType(), "myscript", myscript, True)
End Sub

If you want to display a confirmation style messagebox then add the following to your asp.net server control:

OnClientClick="return confirm('Are you sure you want to proceed?');"

Hope this helps,
