Binding to static class property

I want to bind a textblock text to a property of a static class. Whenever the property value of the static class changes, it should reflect to the textblock which is on the other window or custom control.

You can bind to ANY property on a static class using the x:Static markup extension but if thy do not implement any change tracking, it might cause errors on the refresh!

<TextBlock Text="{Binding Source={x:Static sys:Environment.MachineName}}" />

For those who use nested static classes to organize/seperate constants. If you need to Bind into nested static classes, It seems you need to use a plus (+) operator instead of the dot (.) operator to access the nested class:

{Binding Source={x:Static namespace:StaticClass+NestedStaticClasses.StaticVar}}

Example:

public static class StaticClass
    {
        public static class NestedStaticClasses
        {
            public static readonly int StaticVar= 0;

        }
    }

This has worked for me:

Text="{Binding Source={x:Static MyNamespace:MyStaticClass.MyProperty}, Mode=OneWay}"

Without Mode=OneWay I got an exception.

It worked for me!

When you have static class with static property like this

 namespace App.Classes
 {
     public static class AppData
     {
         private static ConfigModel _configModel;
         public static ConfigModel Configuration
         {
            get { return _configModel; }
            set { _configModel = value; }
         }
     }

     public class ConfigModel : INotifyPropertyChanged
     {
         public event PropertyChangedEventHandler PropertyChanged;

          private bool _text = true;
          public bool Text
          {
               get { return _text ; }
               set { 
                     _text = value; 
                     PropertyChanged?.Invoke(this, new PropertyChangedEventArgs("Text"));
               }
          }
      }
}

You can bind it to xaml like this.

xmlns:c="clr-namespace:App.Classes"

<TextBlock Text="{Binding Path=Text, Source={x:Static c:AppData.Configuration}}"/>
