I want to change the FontStyle in a DataGridView control. But for
some reason, Font.Strikeout is read only. The only thing I can think
of is to create a new Font with the Strikeout FontStyle. Is that
right?

I believe thats correct. I actually got mad in class one time and
started to create a font object that had those properties not set to
readonly so I could change the boolean back and forth thus making my
coding experience easier.

Yes. Fonts are immutable, like Strings. If you want a Font that's just
like an existing one but with something changed, you have to create a new
Font instance based on the existing one, but with the thing(s) you want
changed.

For example, assuming an existing font referenced by a variable
"fontExisting", you can set the strikeout style like this:

Font fontNew = new Font(fontExisting, FontStyle.Strikeout);

Fonts must be constructed from scratch whenever a style change is required.
This is because the font engine recalculates a lot of complex data every
time a font is declared.

To update a font in any control, assign a newly constructed font or one that
you've created earlier and stored for the purpose.
