NavBarViewBase.Click Event

Fires immediately after an end-user performs a click within the view.

Namespace: DevExpress.Xpf.NavBar

Assembly: DevExpress.Xpf.NavBar.v21.2.dll

NuGet Package: DevExpress.Wpf.NavBar

Declaration

C#

public event RoutedEventHandler Click

VB.NET

Public Event Click As RoutedEventHandler

Event Data

The Click event's data class is RoutedEventArgs. The following properties provide information specific to this event:

Property	Description
Handled	Gets or sets a value that indicates the present state of the event handling for a routed event as it travels the route.
OriginalSource	Gets the original reporting source as determined by pure hit testing, before any possible Source adjustment by a parent class.
RoutedEvent	Gets or sets the RoutedEvent associated with this RoutedEventArgs instance.
Source	Gets or sets a reference to the object that raised the event.

The event data class exposes the following methods:

Method	Description
InvokeEventHandler(Delegate, Object)	When overridden in a derived class, provides a way to invoke event handlers in a type-specific way, which can increase efficiency over the base implementation.
OnSetSource(Object)	When overridden in a derived class, provides a notification callback entry point whenever the value of the Source property of an instance changes.

Remarks

Write a Click event handler to perform specific actions each time a user clicks within a view. Note that this event fires immediately after the left mouse button is released. If the button is released when the mouse pointer is not over an item, the event doesn’t fire.

You can use the NavBarViewBase.GetNavBarGroup and NavBarViewBase.GetNavBarItem methods within a handler of the Click event to identify the clicked group or item.

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));
        }
