You may bind the PathGeometry.Figures
property and have a converter that returns a PathFigureCollection
, but I'm afraid you have to live with the fact that the VS Designer complains about the XAML.
<Path.Data>
<GeometryGroup>
<PathGeometry>
<PathGeometry.Figures>
<MultiBinding Converter="{StaticResource PathFiguresConverter}">
<Binding Path="A"/>
<Binding Path="B"/>
<Binding Path="C"/>
</MultiBinding>
</PathGeometry.Figures>
</PathGeometry>
</GeometryGroup>
</Path.Data>
