hi, We need to stop copy paste of few characters like '<' or '>' or any characters which can be potentially dangerous. I know we can set a property RequestValidation to false, but for some reason we would not want to do that.

Probably it is not an issue with the textbox but will occur with other editors as well. In my example (source code attached), I have a WPF TabCont...

If I set the TextBox's IsReadOnly property to True or IsEnabled to False, the wavey red lines disappear and I can't get around it by putting something transparent as this will prevent the user being able...
