The header row is displayed at the top of the FormView control when the HeaderText or HeaderTemplate property is set. Use the HeaderStyle property to control the appearance of the header row in a FormView 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 FormView 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 FormView 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.
