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 NIB: ASP.NET Accessibility.
