Should I remove the "Run" from my TextBlocks?

Question

I've got some TextBlocks that look like so:

        <TextBlock>
                <Run Text="Prev"/>
        </TextBlock>

However, when I created them they didn't have the "Run" jazz. Was this something added by a tool, and if so, why? Should I remove it/what is Run's raison detre?

Answer 1

The Textbox described in your question could also be achieved by using

<TextBlock Text="Prev"/>

Run is just another way of setting the text of a textbox. Is use may become more apparent when you want to format certain parts of text in a textbox e.g.

<TextBlock>
    <Run Text="Number: " FontStyle="Bold" />
    <Run Text="1" />
</TextBlock>

Which might display something like

Number: 1
