问题
I have a project with some 3rd-party controls in it. I have a TextEdit and a MemoEdit in my form and I want to limit the number of characters that the user can enter.

You can wait for the newest version but there are a few workarounds such as masking, helper properties and/or character counting on the text changed event. Here are some links to the workarounds:
