Binding to static class property

Question

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.

Solution 1

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}}" />

Solution 2

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;

        }
    }

Solution 3

This has worked for me:

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

Without Mode=OneWay I got an exception.
