Wpf control size to content?
How do I make a WPF control to change its size according the content in it? Reed Copsey For most controls, you set its height and width to Auto in the XAML, and it will size to fit its content. In code, you set the width/height to double.NaN . For details, see FrameworkElement.Width , particularly the "remarks" section. TabbyCool I had a problem like this whereby I had specified the width of my Window, but had the height set to Auto . The child DockPanel had it's VerticalAlignment set to Top and the Window had it's VerticalContentAlignment set to Top, yet the Window would still be much taller
