Quick Start

The following quick start guide is intended to get you up and running with the MaskedTextBox control. In this quick start, you add a MaskedTextBox control to your application and add various masks to it. In the following example, we created a personal details form for an employee with seven MaskedTextBoxes having different input masks for each field (Name, Social Security Number, Address, Zip Code, Zip+4 Code, Phone Number, and Text Code).

The following Images show how the masked text boxes appear at runtime and after the information is filled in them.
