    I take the error:

    It was not possible to cast object of type"Telerik.OpenAccess.OpenAccessDataSource" to type "System.Web.UI.DataSourceControl".

    What I must fix?

    Hello rent,

    This seems to be a problem in the RadGrid implementation which is already fixed in the latest version. The Code library example is updated and now it should work as expected. We are sorry for the inconvenience.

    Best wishes,
