The main child layout properties



  • Be careful when writing code that uses ActualHeight and ActualWidth (or RenderSize)! Layout occurs asynchronously, so you can’t rely on the values of these properties at all times. It’s safe to access them only within an event handler for the LayoutUpdated event defined on UIElement.
  • Margin and Padding have 1, 2 or 4 values(Left,Top,Right,Bottom).

Visibility
  • Visible : The element is rendered and participates in layout.
  • Collapsed : The element is invisible and does not participate in layout.
  • Hidden : The element is invisible yet still participates in layout.

Alternative to IValueConvert, QuickConverter

https://quickconverter.codeplex.com/ Quick Setup Steps Add the assembly reference to your project. This can also easily be done using  the NuGet package . Add the namespaces to Quick Converter that it will need to know about (before any xaml that uses it is loaded). e.g. In your WPF application's App.xaml.cs file: public   partial   class   App  :  Application { public  App() :  base () { // Setup Quick Converter. // Add the System namespace so we can use primitive types (i.e. int, etc.). QuickConverter. EquationTokenizer .AddNamespace( typeof ( object )); // Add the System.Windows namespace so we can use Visibility.Collapsed, etc. QuickConverter. EquationTokenizer .AddNamespace( typeof (System.Windows. Visibility )); } } Add the Quick Converter namespace to your xaml files so you can ref...
