Set the EnableDescriptionField property to "true" to enable the
        integrated Description field when using a custom provider.
    
    
        Please, note that for the purpose of this example the changes are persisted in the
        session and reset on each visit to the page. Normally, the additional code is not
        required. The provider can be configured through web.config and then it is only
        needed to set the ProviderName property. See the 
            documentation topic on the subject.
    
 
    In this example RadScheduler is bound to a custom provider - the
    XmlSchedulerProvider.
    
    The provider uses an XML document for data storage.
    
    Please, refer to the documentation for the complete source code of the provider
    and information about implementing your own providers.
