    Hi Benjamin,

    Can you try replacing Telerik.Web.UI.DialogHandler.aspx with Telerik.Web.UI.DialogHandler.axd in your web.config file and see how it goes?

    If this does not help, I would advise that you take a look at the following KB article that contains information about the usual scenarios in which the problem is encountered and how to deal with it:
    Error: Web.config registration missing! The Telerik dialogs require a HttpHandler registration in the web.config file.
