Handle the ContextDisposing event, and set the P:System.Web.UI.WebControls.EntityDataSourceContextDisposingEventArgs.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;
}
