Namespace: DevExpress.Xpf.NavBar

Assembly: DevExpress.Xpf.NavBar.v24.1.dll

NuGet Package: DevExpress.Wpf.NavBar

Declaration

C#

public NavBarItem GetNavBarItem(
    RoutedEventArgs e
)

VB.NET

Public Function GetNavBarItem(
    e As RoutedEventArgs
) As NavBarItem

Parameters

Name	Type	Description
e	RoutedEventArgs	A RoutedEventArgs descendant specifying the routed event.

Returns

Type	Description
NavBarItem	A NavBarItem object representing the item related to the specified event. If no item relates to the event, null (Nothing in Visual Basic) is returned.

Remarks

When an end-user performs any actions within a view (such as clicks or hovers the view, etc), responding to these actions may be required, to determine the underlying group or item that corresponds to the event generated by the action. Use the GetNavBarItem method to obtain an item relating to the event that is described by the passed event argument.

C#

//...
using DevExpress.Xpf.NavBar;
//...
        public Window1(){
            InitializeComponent();

            navBar.View.Click += new RoutedEventHandler(View_Click);
        }

        void View_Click(object sender, RoutedEventArgs e){
            NavBarGroup group = navBar.View.GetNavBarGroup(e);
            NavBarItem item = navBar.View.GetNavBarItem(e);
            if (group != null || item != null)
                MessageBox.Show("Click - " + (item != null ? "Item: " + item.Content : "Group: " + group.Header));
        }
