c# - How to remove/delete ContentControl in Canvas WPF -

i'm starting wpf , have problem. please me. thanks, sorry bad english!

i have added contentcontrol canvas, , want remove/delete it.

draw contentcontrol code:

contentcontrol cc = new contentcontrol(); cc.content = shape; cc.height = h; cc.width = w; style s = mycanvas.findresource("designeritemstyle") style; cc.style = s; canvas.setleft(cc, x); canvas.settop(cc, y); mycanvas.children.add(cc);  

i use hittest remove can remove shape

 private void mycanvas_mouserightbuttondown(object sender, mousebuttoneventargs e)     {         point pt = e.getposition((canvas)sender);         hittestresult result = visualtreehelper.hittest(mycanvas, pt);                     if (result != null)         {             mycanvas.children.remove(result.visualhit shape); //it works shape               // have changed  mycanvas.children.remove(result.visualhit contentcontrol);               //but didn't work contentcontrol                    }     }   

it because contentcontrol parent of shape, , canvas's children contains contentcontrol hosts shape. fix issue :)

private void mycanvas_mouserightbuttondown(object sender, mousebuttoneventargs e) {     dependencyobject ob = findancestor<contentcontrol>((dependencyobject)e.source);     if (ob.gettype() == typeof(contentcontrol))             mycanvas.children.remove(ob contentcontrol);             }  public t findancestor<t>(dependencyobject dependencyobject)         t : dependencyobject     {         var parent = visualtreehelper.getparent(dependencyobject);          if (parent == null) return null;          var parentt = parent t;         return parentt ?? findancestor<t>(parent);     }
