    I want to have a validator trigger an error when SOME (any) value exists in the panel.  If everything is good, the webservice just returns "";

    How can I get that?  get_html(), get_value(), html() dont seem to work or be right, and the documentation is pretty gimped for the RadXmlHttpPanel.

    Hello Steve,

    I am not sure that I completely understand your specific scenario. Could you please tell us, when do you try to access the value of the XmlHttpPanel? OnResponseEnding? OnClientResponseError?
    In the OnResponseEnding client-side event, you have access to both, the content that will be pasted in the panel and the value passed from the client. The content can be accessed through the eventArgs, using the get_content() method, and the value through the sender using the get_value() method.
    In the OnClientResponseError client-side event you have access only to the value, again through the sender XmlHttpPanel.
    I have attached a simple project with XmlHttpPanel, that uses WebService to update its content and alerts the value and the content on response ending.

    If this does not resolve your problem, please send us a fully working sample that demonstrates the issues, and state clearly what exactly you want to achieve?

    Kind regards,

    Thank you, I'll try get_content() :)

    Its a form validation if the email address typed in has an error or already exists in the db I disable the input I think I can run with this :)
