MaskedTextBox, there is no support "placeholder" text in the control prior to user input. It would be nice if, instead of showing the mask, it could show placeholder text like native HTML input box does until you begin typing then it would show the mask prompts. Full support for styling the placeholder text using the ::placeholder pseudo class would also be required.
