Isolate this demo as a stand-alone application
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
