 Visited Property
This page is specific to
Microsoft Visual Studio 2008/.NET Framework 3.5

Other versions are also available for the following:
.NET Framework Class Library
LinkLabel..::.Link..::.Visited Property

Gets or sets a value indicating whether the user has visited the link.

Namespace:  System.Windows.Forms
Assembly:  System.Windows.Forms (in System.Windows.Forms.dll)
Visual Basic (Declaration)
Public Property Visited As Boolean
Visual Basic (Usage)
Dim instance As LinkLabel..::.Link
Dim value As Boolean

value = instance.Visited

instance.Visited = value
C#
public bool Visited { get; set; }
Visual C++
public:
property bool Visited {
    bool get ();
    void set (bool value);
}
JScript
public function get Visited () : boolean
public function set Visited (value : boolean)

Property Value

Type: System..::.Boolean
true if the link has been visited; otherwise, false.

A LinkLabel control does not automatically denote that a link is a visited link. To display the link as a visited link, you can set the value of this property to true in an event handler for the LinkClicked event of a LinkLabel. A visited link is displayed using the color specified in the VisitedLinkColor property of the LinkLabel control. Once the form containing the LinkLabel control is closed, the all display state associated with the link is deleted. In order to retain the display state of the link, you need to store the display state of the link in a registry setting associated with your application.

fwz05eta.alert_note(en-us,VS.90).gifNote:

If you have only one link specified in a LinkLabel control, you can use the LinkVisited property of the LinkLabel to specify the link as visited. You can also use the LinkVisited property if you have multiple links defined, but the setting only applies to the first link defined in the control.

The following example demonstrates using the LinkLabel class, with multiple LinkArea sections defined, to display a label on a form. The example demonstrates setting the AutoSize, LinkBehavior, DisabledLinkColor, LinkColor, and VisitedLinkColor properties to customize the look of the LinkLabel. The first LinkArea is specified using the LinkLabel..::.LinkArea property. Additional links are added to the LinkLabel using the LinkLabel..::.LinkCollection..::.Add method. The example handles the LinkClicked event by starting the Web browser for hyperlinks, and displaying a MessageBox for other links.
