将文本限制为TextBox的宽度

Question

I'm using a TextBox to create an editable title on something that looks like a post-it note. I changed to a TextBox from a RichEditBox to see if that could solve my problem, which it didn't, so I'm willing to change back if that helps.

My problem is that I don't want the user to be able to enter more characters than fit in the set width of the TextBox , because I want the whole title to be visible. Setting a fixed limit to the amount of characters that can be entered doesn't really work since for example 10 large M's would fill the width of my TextBox , but other characters will only fill half of it. So I would like to compare the width of the text to the width of the TextBox , so I can restrict input beyond that point.

Edit: I'm using the Segoe UI font, and I don't really consider changing the font to one with characters of equal width as a solution.

Answer 1

将TextBox字体设置为Courier字体，然后所有字符的宽度相等，并且计算max变得很简单。
