FormView.EmptyDataRowStyle Property

Gets a reference to the TableItemStyle object that allows you to set the appearance of the empty data row displayed when the data source bound to a FormView control does not contain any records.

Namespace:  System.Web.UI.WebControls
Assembly:  System.Web (in System.Web.dll)

[PersistenceModeAttribute(PersistenceMode.InnerProperty)]
public TableItemStyle EmptyDataRowStyle { get; }

Property Value

Type: System.Web.UI.WebControls.TableItemStyle
A reference to the TableItemStyle that allows you to set the appearance of the empty data row.

Use the EmptyDataRowStyle property to control the appearance of the empty data row in a FormView control. The empty data 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 FormView 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 FormView 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 use the EmptyDataRowStyle property to specify a custom style for the empty data row displayed when a FormView control is bound to a data source that does not contain any records.
