public virtual void Activate()

解説

MdiTab をアクティブ化すると、その MDI タブが選択され、所有元の TabGroup の MdiTabGroup.SelectedTab が更新されます。

注: Activate メソッドを呼び出すと Form がアクティブになるため、タブをアクティブ化するためにはタブの Form が表示可能である必要があります。

使用例

Visual Basic

Imports Infragistics.Win
Imports Infragistics.Win.UltraWinTabs
Imports Infragistics.Win.UltraWinTabbedMdi

Private Sub ActivateCustomTab()
    ' iterate through all the tab groups
    Dim tabGroup As MdiTabGroup
    For Each tabGroup In Me.ultraTabbedMdiManager1.TabGroups
        ' iterate through all the tab objects 
        ' contained within the tab group
        Dim tab As MdiTab
        For Each tab In tabGroup.Tabs
            ' if the tab is not a custom tab, i.e.
            ' it does not represent a form that implements
            ' the ICustomMdiTab interface. this interface
            ' is implemented by an ultradockmanager
            ' mdi child form but could be used by other
            ' forms
            If tab.IsCustomTab Then
                ' activate the first one
                tab.Activate()
                Return
            End If
