title: How to only allow WPF Window's height resizable?
body: <p>To be specific, I have a <code>Window</code> whose <code>Content</code> is set as a <code>UserControl</code>. And I would like to allow users to drag to increase the height of the <code>Window</code>, but the <code>Width</code> should be fixed and non-resizable. I guess I have such properties to modify but I can't make them behave as I desired:</p>
  
  <ul>
  <li><p><code>Window.SizeToContent</code>, available values: Manual, Width, Height,</p></li>
  <li><p>WidthAndHeight <code>Window.ResizeMode</code>, available values: CanMinimize,<br>
  CanResize, CanResizeWithGrip , NoResize</p></li>
  <li>and of course the Min/Max of Height, Width of the <code>UserControl</code></li>
  </ul>
  
  <p>But what kind of combination can achieve what I want?</p>
