I'm having an issue with multiline text blocks where it is not center aligning properly
The text is coming like
abcde\nabc
This comes out
abcde abc
What I want is
abcde abc
This seems a simple thing and I would have thought that the textblock would center align like that automatically but it does not seem to.
Try the TextAlignment property instead of HorizontalAlignment. First one is the alignment of text in the TextBlock, second the alignment of the TextBlock in the parent container.
TextBlock.TextAlignment should do what you're asking for.
