SelectionChanging/ SelectionChanged events are not fired once an e.Cancel is set to true in SelectionChanging handler

[Ahmed]

I have used the wizard events to control my wizard navigation but once I cancel the navigation for one step using e.Cancel, The SelectionChanging/ SelectionChanged events doesn't  get fired. 

I was using the UI for WPF Q1 2015 and now updated to UI for WPF Q2 2015 but still the same problem exists.

 

check this code sample

 

using System.Windows;
using Telerik.Windows.Data;
using Telerik.Windows.Controls;

namespace WizardNavigation
{
    /// <summary>
    /// Interaction logic for MainWindow.xaml
    /// </summary>
    public partial class MainWindow : Window
    {
        private ObservableItemCollection<WizardPage> collection;
        private int cancelCounter = 1;
        public MainWindow()
        {
            InitializeComponent();

            collection = new ObservableItemCollection<WizardPage>();

            var firstPage = new WizardPage {Content = "My First Page Content"};

            var secondPage = new WizardPage {Content = "My Second Page Content"};

            var thirdPage = new WizardPage {Content = "My Third Page Content"};

            var fourthPage = new WizardPage {Content = "My Fourth Page Content"};

            myWizard.WizardPages.Add(firstPage);
            myWizard.WizardPages.Add(secondPage);
            myWizard.WizardPages.Add(thirdPage);
            myWizard.WizardPages.Add(fourthPage);

            myWizard.Next += myWizard_Next;
            myWizard.SelectionChanging += myWizard_SelectionChanging;
        }

        void myWizard_SelectionChanging(object sender, SelectedPageChangingEventArgs e)
        {
            if (cancelCounter != 2) return;
            e.Cancel = true;
            MessageBox.Show("Cancelled, Click again to navigate");
        }

        void myWizard_Next(object sender, NavigationButtonsEventArgs e)
        {
            // You will need to click the next twice for to move to step 3.
            // SelectionChanging will not be called on the second click
            //SelectionChanging will be called when moving to forth step.
            cancelCounter++;

            var wizard = sender as RadWizard;
            
            if (wizard.SelectedPage.Content == "My First Page Content")
            {
                e.SelectedPageIndex = 2;
            }
        }
    }
}
