Remarks
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, whereSubpropertyis 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.
