Use the DetailsView.RowStyle property to control the appearance of the data rows in a System.Web.UI.WebControls.DetailsView control. When the DetailsView.AlternatingRowStyle property is also set, the data rows are displayed alternating between the DetailsView.RowStyle settings and the DetailsView.AlternatingRowStyle settings. This property is read-only; however, you can set the properties of the System.Web.UI.WebControls.TableItemStyle object it returns. The properties can be set declaratively in the form Property-Subproperty, where Subproperty is a property of the System.Web.UI.WebControls.TableItemStyle object (for example, RowStyle-ForeColor). The properties can also be set programmatically in the form Property.Subproperty (for example, RowStyle.ForeColor). Common settings usually include a custom background color, foreground color, and font properties.
