I am implementing the MVVM pattern and wish to design my interface using the Wizard Control from the WPF ToolKit (Xceed.Wpf.Toolkit).

What I would like to do is bind the Items Source for the Wizard to a List<ViewModelBase> and use a DataTemplate to display it as a page. So far, no Joy. :-(

I have trimmed my code as much as possible but here is the meat of it.

My view XAML:

<xctk:Wizard FinishButtonClosesWindow="True" ItemsSource="{Binding Pages}" />

My Data template:

<DataTemplate DataType="{x:Type vm:ViewModelBase}">

    <xctk:WizardPage Title="{Binding DisplayName}" Description="{Binding DisplayDescription}"/>

</DataTemplate>

In the cs files:
the the VM, the property returning the list is defined:

public List<ViewModelBase> Pages

In the app.xaml.cs:

var viewModel = new ViewModels.winMainViewModel();

winMain window = new winMain();



window.DataContext = viewModel;

window.Show();

The error that is thrown is:

System.NotSupportedException was unhandled HResult=-2146233067

Message=Wizard should only contain WizardPages.

Source=Xceed.Wpf.Toolkit

Any help would be greatly appreciated.

TIA,
Ray

This is apparently not supported as you can see in the source code: https://github.com/xceedsoftware/wpftoolkit/blob/master/ExtendedWPFToolkitSolution/Src/Xceed.Wpf.Toolkit/Wizard/Implementation/Wizard.cs

I am afraid you can only bind to an IEnumerable<Xceed.Wpf.Toolkit.WizardPage>.

Thank you for that response.
Last night I tried playing around with an IConverter class with no luck (yet)

Due to pending deadlines, I decided to write a simple conversion property.

    public List<WizardPage> wizPages

    {

        get

        {

            List<WizardPage> rtn = new List<WizardPage>();

            foreach (ViewModelBase vmb in Pages)

            {

                rtn.Add(new WizardPage()

                {   Title = vmb.DisplayName

                ,   Description = vmb.DisplayDescription

                ,   DataContext = vmb

                });  //  rtn.Add

            }   //  foreach (ViewModelBase vmb in Pages)



            return rtn;

        }

    }
