I am developing an app for sending some feedback. Basically I'm trying to make a TextBox for comments, but I'm used to the WinForms MultiLine=true . I've set MinLines to 3, which is getting there, but preferably I'd like it if the user is able to type wherever in this block - like press enter and do dot points sort of thing. For example: - Item 1 blah - Item 2 blahlb lahbvl d But at the moment the text all stays on one line. - Item 1 blah - Item 2 blahb blahb blah These comments will then help fill the body of an email which is sent.

This question already has an answer here: When to wrap quotes around a shell variable? 5 answers I want to create some scripts for filling some templates and inserting them into my project folder.
