WPF Binding to a property of a static class

Binding to a property of a static class is quite straight forward.

The binding string looks like this:

{x:Static s:MyStaticClass.StaticValue2}

For an example do this:

  1. Create a new folder in your project called Statics.
  2. Add the following class to the Statics folder.
    using System;
    
    namespace BindingToStaticClassExample.Statics
    {
        public static class MyStaticClass
        {
            static MyStaticClass()
            {
                Title = "Binding to properties of Static Classes";
                StaticValue1 = "Test 1";
                StaticValue2 = "Test 2";
                StaticValue3 = "Test 3";
            }
    
            public static String Title { get; set; }
            public static String StaticValue1 { get; set; }
            public static String StaticValue2 { get; set; }
            public static String StaticValue3 { get; set; }
        }
    }
    
  3. Add a reference to the BindingToStaticClassExample.Statics namespace. (See line 4.)
  4. Bind the title to the Title string value of MyStaticClass.
  5. Change the <Grid> to a <StackPanel> (not required just for ease of this example).
  6. Add TextBox elements and bind them to the two string values in MyStaticClass object.
    <Window x:Class="BindingToStaticClassExample.MainWindow"
            xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
            xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
            xmlns:s="clr-namespace:BindingToStaticClassExample.Statics"
            Title="{x:Static s:MyStaticClass.Title}" Height="350" Width="525">
        <StackPanel>
            <TextBox Text="{x:Static s:MyStaticClass.StaticValue1}" />
            <TextBox Text="{x:Static s:MyStaticClass.StaticValue2}" />
            <!-- Not supported and won't work
            <TextBox>
                <TextBox.Text>
                    <Binding Source="{x:Static s:MyStaticClass.StaticValue3}" />
                </TextBox.Text>
            </TextBox>
            -->
        </StackPanel>
    </Window>
    

You now know how to bind to properties of a static class.
