</DrawingBrush.Drawing>
</DrawingBrush>
And I can use it like this:
<Rectangle Fill="{DynamicResource Calender}" />
Now, my question is: how can I
create an attached-property to change all brushes on my resource? e.g. I be able to
create this:
<Rectangle Fill="{DynamicResource Calendar}" attached:IconHelper.Foreground="Blue" />
on my Rectangle and in my resource, I can get:
<DrawingBrush x:Key="Calendar" Stretch="Uniform">
<DrawingBrush.Drawing>
<DrawingGroup>
<DrawingGroup.Children>
<GeometryDrawing Geometry="blah blah">
<GeometryDrawing.Pen>
<Pen Brush={attached:ReadItFromAboveRectangle}/>
</GeometryDrawing.Pen>
</GeometryDrawing>
<GeometryDrawing Geometry="blah blah">
<GeometryDrawing.Pen>
<Pen Brush={attached:ReadItFromAboveRectangle}/>
</GeometryDrawing.Pen>
<!-- etc... -->
Is there any way to read an attached-property on Rectangle in Calendar resource? Or is there any other way to do this? Thanks in advance.
