DataControlFieldHeaderCell Class

In accessibility scenarios, represents a header cell in the rendered table of a tabular ASP.NET data-bound control, such as GridView.

Namespace:  System.Web.UI.WebControls
Assembly:  System.Web (in System.Web.dll)

[AspNetHostingPermissionAttribute(SecurityAction.InheritanceDemand, Level = AspNetHostingPermissionLevel.Minimal)]
[AspNetHostingPermissionAttribute(SecurityAction.LinkDemand, Level = AspNetHostingPermissionLevel.Minimal)]
public class DataControlFieldHeaderCell : DataControlFieldCell
<asp:DataControlFieldHeaderCell />

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:

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.

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
