Format text from resourceDictionary in xaml

Question

I have a text in my resource dictionary:

<ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
                xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
                xmlns:system="clr-namespace:System;assembly=mscorlib">
<system:String x:Key="ResourceDictionaryName" Localization.Comments="$Content(DoNotLocalize)">Loc-en-EN</system:String>

<!--MainControl.xaml-->   
<system:String x:Key="PersonalEmail">Please enter your email./system:String></ResourceDictionary>

and I bind it to xaml this way:

   <TextBlock Text="{DynamicResource PersonalEmail}" Style="{DynamicResource TextBlockStyle}"/>

Is it possible to create style or converter, to show, for example, Please bold, and rest of the text as normal?

Answer 1

String itself does not support rich text format, you can use a Span to show the text.

<TextBlock>
    <Span>
        <Bold>Please</Bold> enter your email.
    </Span>
</TextBlock>

And you can put almost anything into a ResourceDictionary and give it a key, and reference it using that key.

<Window.Resources>
    <Span x:Key="PersonalEmail">
        <Bold>Please</Bold> enter your email.
    </Span>
</Window.Resources>
<Grid>
    <TextBlock>            
        <StaticResource ResourceKey="PersonalEmail" />
    </TextBlock>
</Grid>
