Gets or sets the target window or frame in which to display the Web page content that is linked to when a hyperlink in a BulletedList control is clicked.

Namespace:  System.Web.UI.WebControls
Assembly:  System.Web (in System.Web.dll)

[TypeConverterAttribute(typeof(TargetConverter))]
public virtual string Target { get; set; }
<asp:BulletedList Target="String" />

Property Value

Type: System.String
The target window or frame in which to load the Web page linked to when a hyperlink in a BulletedList is clicked. The default is an empty string ("").

Values must begin with a letter in the range of A through Z (case-insensitive), except for the special values that are listed in the following table, which begin with an underscore.

Value

Description

_blank

Renders the content in a new window without frames.

_parent

Renders the content in the immediate frame-set 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.

NoteNote

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.

Use the Target property to specify the frame or window that displays the Web page that is linked to when a hyperlink in a BulletedList control is clicked. To display the content of the list items as hyperlinks in a BulletedList control, set the BulletedListDisplayMode property to the value HyperLink. Then, set the Value property of each list item to the URL of the Web page to navigate to.

If the Target property is not set, the browser or window with focus refreshes when the hyperlink is clicked.

NoteNote

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 BulletedList 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 Accessibility in Visual Studio and ASP.NET.

The value of this property is stored in view state.

The following code example demonstrates how to create a BulletedList control and set the Target property. When the user selects the HyperLink display mode from the list box, the Target property is set to _blank to display the linked page in a new browser window.
