Add space in DynamicResource? - wpf

Question

I need to add a space before the text, my structure is like this:
<Setter Property="Text" Value="{DynamicResource oneMatch}"/>
so the content displayed should be: " oneMatchContent"
In the past I did a similar thing using StringFormat:
<TextBlock Text="{Binding oneMatch, StringFormat=This is {0}}"/>
But I doesn't see any StringFormat on the Value for setter, any idea?

Answer 1

I can't be sure, since you're so secretive about the context for all this, but my best guess is that that Setter is in a Style that you're applying to a TextBlock.
If that's the case, you could use a Label instead (or any other descendant of ContentControl), and set its ContentStringFormat property as well.
<Style
x:Key="oneMatchLabelStyle"
TargetType="Label"
BasedOn="{StaticResource {x:Type Label}}"
>
<Setter Property="Content" Value="{DynamicResource oneMatch}" />
<Setter Property="ContentStringFormat" Value="This is {0}" />
<!-- Set padding to 0 so it'll look like TextBlock did in your layout -->
<Setter Property="Padding" Value="0" />
</Style>
...
<Label Style="{DynamicResource oneMatchLabelStyle}" />
If you want to add a leading space in the string resource itself, just specify a non-breaking space (Unicode U+00A0) in the XAML. The HTML character entity isn't supported in XAML, so use a hex character entity instead:
<sys:String x:Key="oneMatch"> Blah blah blah</sys:String>
And then use that resource without any special formatting.

You can get fancy with this approach :
<Window.Resources>
<sys:String x:Key="SecretKey">SecretText</sys:String>
<Style x:Key="ContentKey" TargetType="Label">
<Setter Property="Content">
<Setter.Value>
<TextBlock>
<TextBlock.Inlines>
<Run Text=" "/>
<Run Text="{DynamicResource SecretKey}"/>
</TextBlock.Inlines>
</TextBlock>
</Setter.Value>
</Setter>
</Style>
</Window.Resources>
...
<Label Style="{StaticResource ContentKey}"/>
You can use any text in Run now.
