How to use string resource in TextBox

Question

How can a string resource be used for a TextBox?

I understand that I need to use something like:

<x:String x:Key="Placeholder">Placeholder Content</x:String>

but I don't know how.

<TextBox 
    x:Name="nameInput"
    PlaceholderText="Find a setting"
    Width="300" 
    HorizontalAlignment="Left"
    Margin="0,0,0,20" />

Answer 1

If I understand correctly you want to put that Placeholder in TextBox.PlaceholderText. Then define a resource

<Page.Resources>
    <x:String x:Key="Placeholder">Placeholder Content</x:String>
</Page.Resources>

and use it as StaticResource in the TextBox.PlaceholderText

<TextBox PlaceholderText="{StaticResource Placeholder}"/>

You can also define strings in a resource (RESW) file and use Unique Identifiers (Uid) to connect the resource with where it should be used:
