This demo demonstrates binding of RadDataForm to RadClientDataSource. It supports Insert, Update and Delete operations as well as paging.
In order to bind the DataForm to ClientDataSource, the ClientDataSourceID property of the DataForm should be set. To populate the values from the current DataItem to the fields in your template, you need to handle the OnSetValues and OnGetValues events.
