    `Placeholder` is likely what you are looking for - https://www.w3schools.com/tags/att_input_placeholder.asp Or possibly a `Mask` - https://msdn.microsoft.com/en-us/library/system.windows.forms.maskedtextbox%28v=vs.110%29.aspx?f=255&MSPPError=-2147217396 – mjwills Nov 26 '17 at 10:59

In a web application (ASP.NET and HTML) this is called a Placeholder. In a Winform application (or WPF) it's called a Watermark. It's used to set a textbox with a default text (or pattern) which will be erased once the user starts inputting text into it or once it contains a value.
