    Does the XmlHttpPanel Callback function work with Entity Framework?

    I get the following error.
    XmlHttpPanel Callback loading error:
    Exception=The specified named connection is either not found in the configuration, not intended to be used with the Entity Client provider, or not valid....

    With a normal sqlconnection it works great but not with entity framework.

    Thanks,

    Hello MGrassman,

    RadXmlHttpPanel has two modes of operation - one is based on Web Services, and the other is based on ASP.NET 2.0 Callbacks.
    I am not sure whether there will be a problem with using ASP.NET Callbacks in the Entity Framework (I do not think there should be). On the other hand, it should be possible to hook the panel to a webservice without a problem.

    We just released the Q2 2009 officially, and it contains 2 new demos as well as some improved explanations about the RadXmlHttpPanel control. My suggestion is to revisit the demos available here:
    http://demos.telerik.com/aspnet-ajax/xmlhttppanel/examples/default/defaultcs.aspx

    In case there are problems remaining (even when trying with the web service approach) please open a support ticket and send us some more information (e.g. your project or a scaled-down version thereof) for us to examine further.
