GridView.HeaderStyle Property

Note: This property is new in the .NET Framework version 2.0.

Gets a reference to the TableItemStyle object that allows 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)

public TableItemStyle HeaderStyle { get; }
/** @property */
public TableItemStyle get_HeaderStyle ()

public function get HeaderStyle () : TableItemStyle

Property Value

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