DataControlFieldHeaderCell Class
Assembly: System.Web (in system.web.dll)
The DataControlFieldHeaderCell class is used by data tables (such as the GridView control) to represent accessible headers. Tabular controls such as DetailsView and FormView are considered layout tables, and therefore do not require accessible headers and do not use the DataControlFieldHeaderCell class.
The DataControlFieldHeaderCell class is used in two cases:
-
The UseAccessibleHeader property is true.
-
The field is a BoundField object whose DataField property is set as the RowHeaderColumn property.
If neither is the case, a regular DataControlFieldHeaderCell object is used, which renders a <td> instead of a <th> element.
Because the DataControlFieldHeaderCell class supports the AbbreviatedText property, it is used by the GridView control whenever the UseAccessibleHeader property is true.
