I am making my first serious foray into Prism(Unity). I have a module with a toolbar control that gets loaded (properly) into the region that it is supposed to. This toolbar is a listbox with ItemsSource databound to the ToolButtons property on its ViewModel, the constructor for which instantiates and adds three ToolButtons to the ToolButtons collection.

My ToolButton class has three custom DependencyProperties: Title (string), ButtonFace (Image), ActiveDocumentCount (int). Styling is taken care of by a resource dictionary in the module with a Style and associated ControlTemplate. I have databound the properties, but none of the values or the image are displaying (other elements in the style are however) via TemplateBinding.

I am trying to debug the databinding, but to no avail. I do not get any massages pertinent in the Output window, and the 2nd and 3rd suggestions in this blog have produced no output either. I think that if I could get the verbose (i.e. PresentationTraceSources.TraceLevel=High) output, I could figure out what is happening on the databinding front.

EDIT:

Toolbutton Class

public class ToolButton : Button
{
    public ToolButton()
    {
        //DefaultStyleKeyProperty.OverrideMetadata(typeof(ToolButton), new FrameworkPropertyMetadata(typeof(ToolButton)));
    }

    public Image ButtonFace
    {
        get { return (Image)this.GetValue(ButtonFaceProperty); }
        set { this.SetValue(ButtonFaceProperty, value); }
    }
    public static readonly DependencyProperty ButtonFaceProperty =
        DependencyProperty.Register("ButtonFace", typeof(Image), typeof(ToolButton), new PropertyMetadata(null));

    public string Title
    {
        get { return (string)this.GetValue(TitleProperty); }
        set { this.SetValue(TitleProperty, value); }
    }

    public static readonly DependencyProperty TitleProperty =
        DependencyProperty.Register("Title", typeof(string), typeof(ToolButton), new PropertyMetadata(""));

    public int OpenRecordCount
    {
        get { return (int)this.GetValue(OpenRecordCountProperty); }
        set { this.SetValue(OpenRecordCountProperty, value); }
    }

    public static readonly DependencyProperty OpenRecordCountProperty =
        DependencyProperty.Register("OpenRecordCount", typeof(int), typeof(ToolButton), new PropertyMetadata(null));

}
