One ObjectDataSource for two ASP.NET controls

Does anyone know how many trips t开发者_如何学Pythono the database will be made on Select if I use one ObjectDataSource for two ASP.NET controls?

you can cach the data http://www.asp.net/data-access/tutorials/caching-data-with-the-objectdatasource-vb

or make a call to the object

List<T> foo = yourObject.GetSource();
control1.DataSource = foo;
control2.DataSource = foo;
