The mdf mentioned in the read me and that the application uses does not appear to be a part of the source download. If it is could I be pointed to it, please? I cannot find it.

In an effort to better promote Client-Side development that leverages your API, I recommend you update your demos that capture and log events (such as http://demos.telerik.com/aspnet-ajax/input/examples/programming/clientside/apievents/defaultcs.aspx) to behave and act more like the Web Developer Console logging of objects (treenode). 

You could put a control together on the page, but I was thinking at the very least you could just add the console.log lines on these demos.. 

Also, I did a page recommendation on one of your documentation pages that covered clients side events on RadTextBox (I believe).. An event capturing demo that doesn't link to Telerik's EventArgs is kind of pointless to me.. but it would seem there isn't much documentaion in this area. So console logging the event args is just about the best way to review them.

ComboBox in native render mode does not add ID / NAME attributes to the select element.

Stylebuilder seems to be down. I get a server error when trying to create a new skin or edit an existing one?
