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

'Declaration
<PersistenceModeAttribute(PersistenceMode.InnerProperty)> _
Public ReadOnly Property HeaderStyle As TableItemStyle

Property Value

Type: System.Web.UI.WebControls.TableItemStyle
A reference to the TableItemStyle that represents the style of the header row in a DetailsView control.

The header row is displayed at the top of the DetailsView control when the HeaderText or HeaderTemplate property is set. Use the HeaderStyle property to control the appearance of the header row in a DetailsView control. This property is read-only; however, you can set the properties of the TableItemStyle object it returns. The properties can be set declaratively in the form Property-Subproperty, where Subproperty is a property of the TableItemStyle object (for example, HeaderStyle-ForeColor). The properties can also be set programmatically in the form Property.Subproperty (for example, HeaderStyle.ForeColor). Common settings usually include a custom background color, foreground color, and font properties.

The following code example demonstrates how to use the HeaderStyle property to specify the font and style settings for the header row.
