Join a Line and Ellipse -
i did find how bind line ellipse through xaml, i'm not familiar binding, , though i've researched it, still don't understand how binding work user input.
is there way, programmatically have ellipse joined end of line when line rotates on diameter, ellipse rotates it? wrote done in code, not xaml.

never mind, figured out. posted segment of code provided answer.
rads = math.pi * ang / 180; x1 = math.sin(rads) * 80; y1 = math.cos(rads) * 80; x2 = math.sin(rads) * 30; y2 = math.cos(rads) * 30; ellipse ella = new ellipse(); ella.width = 10; ella.height = 10; ella.stroke = brushes.black; ella.fill = brushes.lime; translatetransform ella1 = new translatetransform(70 + x1, 145 - y1); ella.rendertransform = ella1; freecanvas.children.add(ella); ellipse ellb = new ellipse(); ellb.width = 10; ellb.height = 10; ellb.stroke = brushes.black; ellb.fill = brushes.yellow; translatetransform ellb1 = new translatetransform(70 + x2, 145 - y2); ellb.rendertransform = ellb1; freecanvas.children.add(ellb);
