GridView.RowHeaderColumn Property

Gets or sets the name of the column to use as the column header for the GridView control. This property is provided to make the control more accessible to users of assistive technology devices.

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

[TypeConverterAttribute("System.Web.UI.Design.DataColumnSelectionConverter, System.Design, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a")]
public virtual string RowHeaderColumn { get; set; }
<asp:GridView RowHeaderColumn="String" />

Property Value

Type: System.String
The name of the column to use as the column header. The default is an empty string (""), which indicates that this property is not set.

In HTML, the header of a table can be associated with either a row or a column. The direction is specified by setting the scope attribute of the <th> elements. The GridView control has a built-in header row that can be displayed by setting the ShowHeader property to true. You can also optionally specify a header column (usually the first or last column in the GridView control) by setting this property. When this property is set, all cells in the column that corresponds to the specified field name are rendered as <th scope="row"> elements.

NoteNote

Although the specified column is treated like a header, the HeaderStyle, ShowHeader, and UseAccessibleHeader properties do not apply to the header column.

The default rendering of the <th> element is preserved, rendering text as bold and centered horizontally. Developers can override the behavior of the <th> element using a cascading style sheet.

NoteNote

This property works only with bound fields. It does not work with template fields.

The following example demonstrates how to use the RowHeaderColumn property to display a header column in a GridView control.
