Activate Method

Activates the associated Mdi child Form.
Syntax
'Declaration
 
Public Overridable Sub Activate() 
public virtual void Activate()
Remarks

Activating an MdiTab will cause it to be selected and will update the MdiTabGroup.SelectedTab of the owning TabGroup.

Note: A tab's Form must be visible in order to activate the tab since the Activate method results in activating the Form

Example
The following example demonstrates how to iterate the tab groups and their tabs as well as activate a tab item.

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
        Next
    Next
End Sub
using Infragistics.Win;
using Infragistics.Win.UltraWinTabs;
using Infragistics.Win.UltraWinTabbedMdi;

private void ActivateCustomTab()
{
	// iterate through all the tab groups
	foreach(MdiTabGroup tabGroup in this.ultraTabbedMdiManager1.TabGroups)
	{
		// iterate through all the tab objects 
		// contained within the tab group
		foreach(MdiTab 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)
				continue;

			// activate the first one
			tab.Activate();
			return;
		}
	}
}
