Note: This property is new in the .NET Framework version 2.0.
Gets or sets the user-defined content for the empty data row rendered when a
FormView control is bound to a data source that does not contain any records.
Namespace: System.Web.UI.WebControls
Assembly: System.Web (in system.web.dll)
Syntax
Visual Basic (Declaration)
<TemplateContainerAttribute(GetType(FormView))> _
Public Overridable Property EmptyDataTemplate As ITemplate
Dim instance As FormView
Dim value As ITemplate
value = instance.EmptyDataTemplate
instance.EmptyDataTemplate = value
[TemplateContainerAttribute(typeof(FormView))]
public virtual ITemplate EmptyDataTemplate { get; set; }
[TemplateContainerAttribute(typeof(FormView))]
public:
virtual property ITemplate^ EmptyDataTemplate {
ITemplate^ get ();
void set (ITemplate^ value);
}
/** @property */
public ITemplate get_EmptyDataTemplate ()
/** @property */
public void set_EmptyDataTemplate (ITemplate value)
public function get EmptyDataTemplate () : ITemplate
public function set EmptyDataTemplate (value : ITemplate)
Property Value
A
System.Web.UI.ITemplate that contains the custom content for the empty data row. The default value is a null reference (
Nothing in Visual Basic), which indicates that this property is not set.
Remarks
The empty data row is displayed in a FormView control when the data source that is bound to the control does not contain any records. You can define your own custom user interface (UI) for the empty data row by using the EmptyDataTemplate property. To specify a custom template for the empty data row, first place <EmptyDataTemplate> tags between the opening and closing tags of the FormView control. You can then list the contents of the template between the opening and closing <EmptyDataTemplate> tags. To control the style of the empty data row, use the EmptyDataRowStyle property. Alternatively, you can use the built-in UI for the empty data row by setting the EmptyDataText property instead of this property.

| If both the EmptyDataText and EmptyDataTemplate properties are set, the EmptyDataTemplate property takes precedence. |
Example
The following example demonstrates how to define a custom template for the empty data row displayed when a FormView control is bound to a data source that does not contain any records.
