The RequiredFieldValidator

The RequiredFieldValidator, ensures the user provides a valid value for your control.

To get started, create a new web site called RequiredFieldValidator. You’ll create the bug reporting web page shown in Design view in Figure 8-1.

Figure 8-1. Validator bug report in the designer

When the user clicks the Submit Bug button, the page is validated to ensure each field has been modified. If not, the offending field is marked with an error message in red, as shown in Figure 8-2.

I wanted to learn C and C++, but it didn't click for me until I picked up an O'Reilly book. When I went on the O’Reilly platform, I was astonished to find all the books there, plus live events and sandboxes so you could play around with the technology.

Addison B.

I’ve been on the O’Reilly platform for more than eight years. I use a couple of learning platforms, but I'm on O'Reilly more than anybody else. When you're there, you start learning. I'm never disappointed.

Amir M.
