VS 2012中的WPF设计器问题

Question

I'm new to WPF and I'm having problems in building a simple UI. When I place a button at a random position in the window it doesn't appear EXACTLY where it would appear in the designer. Why's that, there wasn't such problem with the Windows Forms designer, let's say.

Here's a screenshot of what I mean: http://s14.postimg.org/kjs0vvpqn/wpf.png

Isn't there a way to make the button appear exactly how it would appear in the designer?

If you want to place a button to have a WYSIWYG position, wrap it into a Canvas , rather than a grid or StackPanel. For grid or stackpanel, the position is controlled by HorizontalLayout, Margin, Padding etc., whereas for Canvas, you can set the top and left property directly.
