Set superscript and subscript in formatted text in wpf

Question

How can i set some text as subscript/superscript in FormattedText in wpf

Answer 1

You can use something like <TextBlock>5x<Run BaselineAlignment="Superscript">4</Run> + 4</TextBlock>.

However, as far as I know, you will have to reduce the font-size yourself.

Answer 2

You use Typography.Variants:

<TextBlock>
    <Run>Normal Text</Run>
    <Run Typography.Variants="Superscript">Superscript Text</Run>
    <Run Typography.Variants="Subscript">Subscript Text</Run>
</TextBlock>

Answer 3

I don't know if you need this to work with FormattedText specifically, or you mean derivations of Inline, but the following will work on Inlines, even if Typography.Variants="Superscript" fails to work.

TextRange selection = new TextRange(document.ContentStart, document.ContentEnd);
selection.ApplyPropertyValue(Inline.BaselineAlignmentProperty, BaselineAlignment.Superscript);

Hope it helps!
