Question

I would like to prepend a text in a data-bound text block:

<TextBlock Text="{Binding Title}" />

The text that is shown is:

"My title"

What I want to be shown is:

This is "My title"

Answer 1

You can use the StringFormat property of the binding:

 <TextBlock Text="{Binding Title, StringFormat=This is {0}}"></TextBlock>
