Styles...

I have a WebContainerControl in my project.
In that container is a canvas object and I want to draw an arrowed line of a specific color.
How can I use a webstyle to figure out what color to draw the line in?

If you’re using a canvas you get to pick what color you draw it as with the paint event. You could subclass the Canvas and add a color property so you could resuse the ArrowCanvas with different colors. This would also allow you to not need to use the Outter Container Control as well.
