Hi
I would like to navigate to a specific page using the SelectedPageChanging event.
What would be the call to have the next page be changed to the PaymentDetails WizardPage.

   private void wizard_SelectedPageChanging(object sender, WizardSelectedPageChangeEventArgs e)
        {
            if (e.OldSelectedPage == ItemsNeedAction)
            {
                if (actionNowNo.IsChecked == true)
                {
                    //I want to navigate to the PaymentDetails WizardPage here
                   ItemsNeedAction.NextPage = PaymentDetails;  //doesnt work
                }
            }
        }
Thanks
Joe

Hi Joe,

I think you'd want to do something like this:
e.Cancel = true;
wizard.SelectedPage = PaymentDetails;

Hi
When I paste that code in, I get "System.StackOverflowException was unhandled" &
"An unhandled exception of type 'System.StackOverflowException' occurred in WindowsBase.dll"

e.Cancel = true; 
wizard.SelectedPage = PaymentDetails; //I get a System.StackOverflowException here
I have also upgraded to the latest version 3.5.425.0

Hi Joe,

Do you have a simple project you could email over that shows this happening? Perhaps we can make a change to allow this sort of thing to work for the next maintenance release.

Hi Joe,

Strange, we never received it. I wonder if since you sent it from a gmail account it got blocked. I added your email address you registered with us as a safe sender to our mail server. Please try to send it again.

Joe,

Try putting this in there.. it should prevent the recursion your code is causing:
if (e.NewSelectedPage != PaymentDetails) {
   e.Cancel = true;
   wizard.SelectedPage = PaymentDetails;
}
It just checks to see if we are already going to the correct page. If so, there is no need to cancel and set the selected page again, which is what is causing the infinite recursion.
