WDE interaction Extension

Hello,

Having a few problems with customizing WDE 8.5 to show a browser within the interaction extension window. I have managed to do this separately (see other post) but want to see it within a WDE interaction window.
The provided sample (InteractionExtensionSample) is close to what I want to achieve so have used this as a template.
The aim to replace the existing ‘MySampleView’ content (yellow box, black circle, reset button) with a browser containing a url from an attached date field.

Generally speaking I think the following files are needed, or require amendments.
MySampleView.xaml
MySampleView.xaml.cs
IMySampleView.cs
InteractionExtensionSampleModule.cs

What is confusing slightly is what code is required for each file.

For MySampleView.xaml I have added a browser control to the existing content (removed the reset button/black circle and added the bold text below):

<Grid>

For the MySampleView.xaml.cs, i have added code from a Genesys documentation on using URI from attached data, additional code in bold:
namespace Genesyslab.Desktop.Modules.InteractionExtensionSample.MySample
{
///

/// Interaction logic for MySampleView.xaml
///

public partial class MySampleView : UserControl, IMySampleView
{
readonly IObjectContainer container;

    public MySampleView(IMySampleViewModel mySampleViewModel, IObjectContainer container)
    {
        this.Model = mySampleViewModel;
        this.container = container;

        InitializeComponent();

        Width = Double.NaN;
        Height = Double.NaN;
        MinSize = new MSize() { Width = 400.0, Height = 400.0 };
    }

    MSize _MinSize;
    public MSize MinSize
    {
        get { return _MinSize; }  // (MSize)base.GetValue(MinSizeProperty); }
        set
        {
            _MinSize = value; // base.SetValue(MinSizeProperty, value);
            OnPropertyChanged("MinSize");
        }
    }


    #region INotifyPropertyChanged Members

    public event PropertyChangedEventHandler PropertyChanged;

    protected void OnPropertyChanged(string name)
    {
        if (PropertyChanged != null)
        {
            PropertyChanged(this, new PropertyChangedEventArgs(name));
        }
    }

    #endregion
    #region IMySampleView Members

    /// <summary>
    /// Gets or sets the model.
    /// </summary>
    /// <value>The model.</value>
    public IMySampleViewModel Model
    {
        get { return this.DataContext as IMySampleViewModel; }
        set { this.DataContext = value; }
    }

    #endregion

    #region IView Members

    /// <summary>
    /// Gets or sets the context.
    /// </summary>
    /// <value>The context.</value>
    public object Context { get; set; }

    /// <summary>
    /// Creates this instance.
    /// </summary>
    public void Create()

{
{
IDictionary<string, object> contextDictionary = (Context as IDictionary<string, object>);
object caseObject;
if (contextDictionary.TryGetValue(“Case”, out caseObject))
{
ICase theCase = caseObject as ICase;
// Get the URL from the interaction attached data
string urlField = theCase.MainInteraction.GetAttachedData(“URL_Field”) as string;
// Get URI to navigate to
Uri uri = new Uri(urlField, UriKind.RelativeOrAbsolute);
// Create the web browser control and add it to the view (here an UserControl)
System.Windows.Controls.WebBrowser myWebBrowser = new System.Windows.Controls.WebBrowser();
this.Content = myWebBrowser;
myWebBrowser.Navigate(uri);
}
}
}

    /// <summary>
    /// Destroys this instance.
    /// </summary>
    public void Destroy()
    {
    }

    #endregion

    private void Button_Click(object sender, System.Windows.RoutedEventArgs e)
    {
        Model.ResetCounter();
    }

    private void MySampleView_Loaded(object sender, RoutedEventArgs e)
    {
    }

}

}

I have not changed the IMySampleView.cs or InteractionExtensionSampleModule.cs files as I don’t think this is needed because the interaction extension is already placed within the location needed.
Am I on the right lines? I know there is much more code within the ‘xaml’ and ‘xaml cs’ files but if I start to remove any snippets that I think are not needed - there are errors during build/debug.
There may also be a better or simpler way to do this.

thanks.
