Use the DataControlField.Visible property to show or hide System.Web.UI.WebControls.DataControlField objects in a data-bound control.
If the the DataControlField.Visible property is false, the data values are not displayed and do not make a round-trip to the client. If you want to round-trip the data for a field that is not visible, add the field name to the DataKeyNames property of the data-bound control.
