If you want to create a responsive menu (NavBar), use the ResponsiveNavigation control instead.
Sample 1: Basic Usage
The NavigationItem control has the NavigateUrl property which specifies target URL, or the Click property which invokes a command on the viewmodel.
The Text property defines the contents of the item. Alternatively, you can also place the contents inside the control.
The IsSelected and IsDisabled properties define whether the control gets the active or disabled CSS classes.
<bs:NavigationBar>
<bs:NavigationItem NavigateUrl="https://www.google.com/"
Text="Google"
IsSelected="true" />
<bs:NavigationItem NavigateUrl="http://www.w3schools.com/html/"
Text="W3 Schools"
IsDisabled="true" />
</bs:NavigationBar>Sample 2: NavigationBar Appearance
The Type and IsJustified properties can modify the visual appearance of the navigation bar.
<bs:NavigationBar Type="Pills">
<bs:NavigationItem NavigateUrl="https://www.google.com/" Text="Google" IsSelected="true"/>
<bs:NavigationItem NavigateUrl="http://www.w3schools.com/html/" Text="W3Schools"/>
</bs:NavigationBar>
<br />
<bs:NavigationBar Type="PillsStacked">
<bs:NavigationItem NavigateUrl="https://www.google.com/" Text="Google" IsSelected="true"/>
<bs:NavigationItem NavigateUrl="http://www.w3schools.com/html/" Text="W3Schools"/>
</bs:NavigationBar>
<br />
<bs:NavigationBar Type="Tabs">
<bs:NavigationItem NavigateUrl="https://www.google.com/" Text="Google" IsSelected="true"/>
<bs:NavigationItem NavigateUrl="http://www.w3schools.com/html/" Text="W3Schools"/>
</bs:NavigationBar>
<br />
<bs:NavigationBar IsJustified="true">
<bs:NavigationItem NavigateUrl="https://www.google.com/" Text="Google" IsSelected="true"/>
<bs:NavigationItem NavigateUrl="http://www.w3schools.com/html/" Text="W3Schools"/>
</bs:NavigationBar>Sample 3: Data Binding Navigation Items
The NavigationBar control can also generate the items from a collection in the viewmodel.
The DataSource property define the collection of objects which will be used to create the list items.
Using the following properties, you can specify, which properties of objects in the collection will be used to configure the navigation items.
