GridView.HeaderStyle Property

Gets a reference to the TableItemStyle object that enables you to set the appearance of the header row in a GridView control.

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

[PersistenceModeAttribute(PersistenceMode.InnerProperty)]
public TableItemStyle HeaderStyle { get; }

Property Value

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

Use the HeaderStyle property to control the appearance of the header row in a GridView control. This property is read-only; however, you can set the properties of the TableItemStyle object it returns. The properties can be set declaratively using one of the following methods:

  • Place an attribute in the opening tag of the GridView control in the form Property-Subproperty, where Subproperty is a property of the TableItemStyle object (for example, HeaderStyle-ForeColor).

  • Nest a <HeaderStyle> element between the opening and closing tags of the GridView control.

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 example demonstrates how to use the HeaderStyle property to define a custom style for the header row in a GridView control.
