Remarks
When the Menu control is bound to a data source, use the Target property to specify the window or frame in which to display the Web content linked to a menu item when that menu item is clicked.
Note
Setting this property overrides the Menu.Target property of the Menu control for the menu items to which the MenuItemBinding object is applied. You can selectively override this property by setting the MenuItem.Target property of each menu item directly.
Target values must begin with a letter in the range of A through Z (case-insensitive), except for certain special values that begin with an underscore, as shown in the following table.
| Target value | Description |
|---|---|
_blank |
Renders the content in a new window without frames. |
_parent |
Renders the content in the immediate frameset parent. |
_search |
Renders the content in the search pane. |
_self |
Renders the content in the frame with focus. |
_top |
Renders the content in the full window without frames. |
Note
Check your browser documentation to determine if the _search value is supported. For example, Microsoft Internet Explorer 5.0 and later support the _search target value.
Note
The Target property renders as a target attribute. The target attribute on anchor elements is not allowed in the XHTML 1.1 document type definition. Do not set the Target property if the rendered output for the MenuItemBinding object must be XHTML 1.1 compliant. For more information, refer to the topic XHTML Standards in Visual Studio and ASP.NET.
When creating accessible Web pages, it is strongly recommended you avoid using the Target property to target another window. For more information, see ASP.NET Accessibility.
