Regarding your second question - the difference between Template and ClientTemplate is where the template is actually rendered. The Template is rendered on the server when server binding is used, meaning that when the page is loaded in the browser the template will already be rendered as HTML code. In contrast, the ClientTemplate is used with Ajax binding and is rendered after the page has loaded and the data is fetched from the server.
As a small sign of our appreciation for bringing the undocumented features to our attention I have updated your Telerik points.
