Configuring page provider capabilities

Page providers requires some configuration. In addition to the obvious ones like name, type and entryPoint you should also define what capabilities your page provider supports, such as Create, Edit, Delete and Search. If you, for example, specify that your provider does not support delete, all delete related ui in edit mode will be disabled for your providers pages. More details on capabilities can be found in the Configuration section of the Page Provider Tech Note.

In almost all examples I have seen for page provider configuration, capabilities are specified in web.config. In my opinion, capabilities should not be defined in configuration. This could lead to, by accident, specifying more capabilities than what is actually implemented in code. I think the best place for this kind of configuration is code. Fortunately, the Capabilities property in PageProviderBase is virtual, which means you can override it and configure it there.

public override PageProviderCapabilities Capabilities
{
    get
    {
        return PageProviderCapabilities.Create | 
            PageProviderCapabilities.Edit | 
            PageProviderCapabilities.Search;
    }
}
