Property Value
Type: System.Web.UI.ITemplateA System.Web.UI.ITemplate that contains the custom content for the empty data row. The default value is null, which indicates that this property is not set.
The empty data row is displayed in a GridView 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 GridView 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.
For information about how to programmatically access controls that you declare in an empty data template, see How to: Access Server Controls by ID.
Note

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