Could you please elaborate about this? We are always trying to improve our API.Was a difficult birth as usual and more than I like but in the end it works.
There is no such example, but using MouseDragElementBehavior you can move any UI element inside the bounds of a container using the mouse.While we're at it, do you have an example (in C++ would be nice) of a dragable window that could be positioned anywhere on the screen on top of a layout. Is that even possible with Noesis?

topWindow->GetChildren()->Add(messageWindow);

topWindow->GetChildren()->Remove(messageWindow);In the Localization demo I put as an example before we defined a SolidColorBrush in xaml so the Converter could return a Color directly, which will be better to avoid creating new brush objects every time the binding changes:For example setting the color to a button according to some value in code. I take it you reimplemented WPF functionality here and this is how it works and you can't do much about it. But for a newcomer it's pretty hard to understand why I simply can't set a color to an UI element.
