This example illustrates how automatic insert, update and delete data operations can be achieved with RadListView and all ASP 3.5 DataSource control types like EntityDataSource.


What you need to do is to set the following properties:
  • DataSourceID property of the RadListView to the ID of the Data Source control
  • EnableDelete, EnableInsert, EnableUpdate properties of the Data Source control to true
  • DataKeyNames property of RadListView by listing the data source table Primary keys
  • Use the two-way ASP.NET binding expressions Bind() for the editable fields in the listview's body

You may also see how to utilize Telerik OpenAccess ORM as a data access layer for our AJAX controls by visiting the OpenAccess ORM live demos here.
