GridView.EmptyDataRowStyle Property
Gets a reference to the TableItemStyle object that enables you to set the appearance of the empty data row rendered when a GridView control is bound to a data source that does not contain any records.
Assembly: System.Web (in System.Web.dll)
[PersistenceModeAttribute(PersistenceMode.InnerProperty)] public TableItemStyle EmptyDataRowStyle { get; }
Property Value
Type: System.Web.UI.WebControls.TableItemStyleA reference to the TableItemStyle that enables you to set the appearance of the null row.
Use the EmptyDataRowStyle property to control the appearance of the null row in a GridView control. The null row is displayed when the data source that is bound to the control does not contain any records. 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, EmptyDataRowStyle-ForeColor).
Nest an <EmptyDataRowStyle> 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, EmptyDataRowStyle.ForeColor). Common settings usually include a custom background color, foreground color, and font properties.
The following example demonstrates how to set the EmptyDataRowStyle property declaratively to specify a light blue background and a red font for the null row.
