Just like the navigation pane in Microsoft® Outlook®, end users can collapse xamOutlookBar™ at run time to maximize their screen real estate. In addition to your end users collapsing xamOutlookBar, you can also collapse xamOutlookBar programmatically by setting its IsMinimized property to True.
The following example code demonstrates how to collapse xamOutlookBar.
In XAML:
<igOutlookBar:XamOutlookBar Name="xamOutlookBar1"
HorizontalAlignment="Left"
IsMinimized="True" />
In Visual Basic:
Me.xamOutlookBar1.IsMinimized = True
In C#:
this.xamOutlookBar1.IsMinimized = true;
