Apologies for the inconvenience caused.
Currently, the example that you are looking for is moved from our web site to Telerik OpenAccess Samples Kit and is updated with some of our new features and with our OpenAccessLinqDataSource control.
The OpenAccessLinqDataSource control is designed to replace OpenAccessDataSource. Basically, it supports data binding scenarios in Web Applications based on OpenAccess and internally uses LINQ as query engine, which gives much wider abilities to query data (more about it you can find here
). It also implements a variety of events that allow you to configure it in runtime - check this set of articles
You can download the Samples Kit from here
and I suggest that you take a look at the examples in the ASP.NET categories.
I hope that helps. If you have any other questions, do not hesitate to get back to us.
