using \textunderscore just crashes the Formulacontrol on WPF

[TheOOnewbie]

while trying to show a formula in my wpf program, the control kept crashing whenever I try to use the command that is used to write underscores =>(\textunderscore ) is there a way to add a certain library so the control could support such commands ?

if not what would you do in this case ?

_ command is also not working

When talking about something "crashing" (an exception thrown perhaps?), it's always useful to provide a stack trace.

_ command is also not working

Is it even a command? Could you please give an example?

Hi,

regarding the crashing error, no there was no exception thrown, the whole control turns into a single red dot,

this happens when I try to use on of the either (_) or(\textunderscore) in the formula property of the control

I hope this helps you to recreate the error.

I was able to reproduce the issue. We have no commands \textunderscore or \_, and there's a reason for that: turns out that the Computer Modern font we use doesn't have a _ character.

So, it is very tricky to add. Please use \text{_} for now.

Answering to your other question,

is there a way to add a certain library so the control could support such commands ?

We are considering making WPF-Math user-extendable, but that still requires a lot of ongoing work. See #154 for details.
