How to add text with sub/supstring?

[Ivan]

Please help with adding some text into run with substring numbers (chemical formula)
How to do this?

Hello Ivan,

From what I understand you would like to insert subscript (or superscript) numbers in text content. That can be achieved through the BaselineAlignment property of a Run.

However, the normal and subscript parts of the text must be separate runs, so that they each have different formatting.

Example:

paragraph.Inlines.AddRun("normal text");
var subscriptText = paragraph.Inlines.AddRun("1");
subscriptText.BaselineAlignment = BaselineAlignment.Subscript;

Hope this helps.

Regards,
Yoan
