LinkLabel.LinkBehavior プロパティ
アセンブリ: System.Windows.Forms (system.windows.forms.dll 内)

Dim instance As LinkLabel Dim value As LinkBehavior value = instance.LinkBehavior instance.LinkBehavior = value
/** @property */ public LinkBehavior get_LinkBehavior () /** @property */ public void set_LinkBehavior (LinkBehavior value)
public function get LinkBehavior () : LinkBehavior public function set LinkBehavior (value : LinkBehavior)
LinkBehavior 値の 1 つ。既定値は LinkBehavior.SystemDefault です。


このプロパティを使用すると、コントロールに表示されるときのリンクの動作を指定できます。たとえば、マウスのポインタがリンク上にあるときにだけリンク テキストを下線付きで表示する場合は、このプロパティを LinkBehavior.HoverUnderline に設定します。リンクに関連付けることができる動作の種類については、LinkBehavior のトピックを参照してください。

複数の LinkArea セクションが定義されている LinkLabel クラスを使用して、フォームにラベルを表示する例を次に示します。AutoSize、LinkBehavior、DisabledLinkColor、LinkColor、および VisitedLinkColor などの各プロパティを設定して LinkLabel の外観をカスタマイズする例を次に示します。最初の LinkArea は、LinkLabel.LinkArea プロパティを使用して指定されます。追加のリンクは、LinkLabel.LinkCollection.Add メソッドを使用して LinkLabel に追加されます。この例では、LinkClicked イベントを使用して、Web ブラウザを起動してハイパーリンクにアクセスし、その他のリンクを示す MessageBox を表示しています。
