Assembly: System.Web (in System.Web.dll)
Use the property to control the appearance of the field header column in a DetailsView control. This is the column that contains the field names of the data values. 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, FieldHeaderStyle-ForeColor). The properties can also be set programmatically in the form Property.Subproperty (for example, FieldHeaderStyle.ForeColor). Common settings usually include a custom background color, foreground color, and font properties.
