c# - Setting Label Text in XAML to string constant

Question

I have a single string constant that I have to re-use in several different XAML layouts, so instead of duplicating it, I'd like to just bind it to a constant.

I have a class which defines the string in C#:

public static class StringConstants
{
     public static string MyString { get { return "SomeConstant"; } }
}

I'd like to be able to set the value through XAML via something like the following:

<Label Content="{Binding local:StringConstants.MyString}"/>

Is this achievable? I've searched for examples, but I've only found samples that involve some tinkering in the code-behind and I'm wondering if there's a simpler, XAML-only solution if I know that I just need to set the value once based on a string value that will never change.

Answer 1

You are binding to a static member so you should use x:Static Markup Extension:

<Label Content="{Binding Source={x:Static local:StringConstants.MyString}}"/>

According to @H.B.'s comment it's not necessary to use Binding so it's simpler to use:

<Label Content="{x:Static local:StringConstants.MyString}"/>
