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.
   ?

   1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20

   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.

   1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17

   <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.
