Handle the ContextDisposing event, and set the Cancel property of the EntityDataSourceContextDisposingEventArgs to true. This prevents the disposal of the ObjectContext. For more information, see Object Context Life-Cycle Management (EntityDataSource).

This example maintains the ObjectContext for future reference by handling the ContextCreated event.

        protected void EntityDataSource2_ContextDisposing(object sender, 
            EntityDataSourceContextDisposingEventArgs e)
        {
            e.Cancel = true;
        }
