Here are some of the problems that I have encountered:

1. RequiredFieldValidator controls in ASP.

definition and Usage: The RequiredFieldValidator control is used to make an input control a required field.

With this control, validation fails if the initial value of the input value is not changed. By default, the initial value is an empty string ("").

This is I write input box check encountered problems, simply say is to determine whether the input is not empty, very good understanding.
