Still havent found out what was wrong with this, but here is one of the FrameworkElements Im trying to bind the ItemsControl to
public class SourceDiagramBase : FrameworkElement, INotifyPropertyChanged
{
private VisualCollection \_children;
public SourceDiagramBase()
{
\_children = new VisualCollection(this);
\_children.Add(CreateDrawingVisual());
}
protected override int VisualChildrenCount { get { return \_children.Count; } }
protected override Visual GetVisualChild(int index)
{
return \_children\[index\];
}
public double Scale
{
get { return (double)GetValue(ScaleProperty); }
set { SetValue(ScaleProperty, value); }
}
// Using a DependencyProperty as the backing store for Scale. This enables animation, styling, binding, etc...
public static readonly DependencyProperty ScaleProperty =
DependencyProperty.Register("Scale", typeof(double), typeof(SourceDiagramBase), new PropertyMetadata(20d));
protected override Size MeasureOverride(Size availableSize)
{
return new Size(this.Scale \* 12d, this.Scale \* 12d);
}
private DrawingVisual CreateDrawingVisual()
{
DrawingVisual drawingVisual = new DrawingVisual();
DrawingContext drawingContext = drawingVisual.RenderOpen();
drawingContext.PushTransform(new ScaleTransform(this.Scale, this.Scale));
double thick = 0.04;
drawingContext.DrawEllipse(Brushes.Transparent, new Pen(Brushes.Black, thick), new Point(6, 6), 3,3);
drawingContext.DrawLine(new Pen(Brushes.Black, thick), new Point(6, 3), new Point(6, 2));
drawingContext.DrawLine(new Pen(Brushes.Black, thick), new Point(6, 9), new Point(6, 10));
drawingContext.DrawLine(new Pen(Brushes.Black, thick), new Point(6, 2), new Point(12, 2));
drawingContext.DrawLine(new Pen(Brushes.Black, thick), new Point(6, 10), new Point(12, 10));
drawingContext.Close();
return drawingVisual;
}
public event PropertyChangedEventHandler PropertyChanged;
// This method is called by the Set accessor of each property.
// The CallerMemberName attribute that is applied to the optional propertyName
