The ErrorProvider is a provider controla special type of user-interface ingredient introduced in Chapter 4. How can I name the errorprovider which has been added to several. I wish to use the same routine across several input forms. Intellisense tells me that errorprovider1 is not a member of. I know that not all forms have them unless I add one.

In C# (Visual Studio 2017) when developing a forms application there is a 'ErrorProvider' component that is easy to use and displays an icon on the right (exclamation mark by default) with a hint that can contain the error text. what i was suggesting was, under each control that needs to be validated, add a label just beneath them with empty text.

The Tooltip class represents a significant departure from how tooltips were implemented in earlier versions of Visual Studio.
