Drag one Text Box control and give it an ID of First Name Text Box, two Button controls (Submit Button and Cancel Button), and one Required Field Validator (First Name Required Field Validator). You can validate the following server controls: Text Box, List Box, Drop Down List, Radio Button List, and the following HTML controls: Html Input Text, Html Input File, Html Select, and Html Text Area.
Before accepting data from over the network you need to ensure all of the required fields have been filled out and conform to your formats and business rules. NET provides a number of validation controls to ease the burden of performing validation on both sides of the network. To walk along with the example, create a new web application in Visual Studio . Once the application is setup, right click on the empty web form, select Properties from the context menu, and change the Page Layout property to Flow Layout. All of the validation controls must have the Control To Validate property set before rendering the page or the control throws an exception.
Place four controls from the Web forms section of the Toolbox onto the form. The one exclusion to this rule is the Custom Validator component.
