Validating web site finding and dating marijuana smokers in your area
If you have already created a Web site in Visual Studio (for example, by working with the topic ), you can use that Web site and skip to "Adding Controls" later in this walkthrough. In effect, you write client script that duplicates the logic that your server-side validation performs.Writing client-side custom validation code is not always practical (for example, if the custom code validates a user's entry by looking in a server-side database).Users can check a box to indicate that they want telephone confirmation of their reservation.(The default for this page, if implemented, would be e-mail confirmation.) By default, the Web Forms page automatically validates that malicious users are not attempting to send script to your application even if you do not use validation controls. For information about the difference between these Web project types, see text box can be converted to a date value. The first is the custom validation code that runs when the page is submitted.For more information, see In the first part of the walkthrough, you will create a Web site and a page where you can work with styles. You must always have server-side validation logic for a control as well. NET validator controls to check user input in a Web page.You will work with some controls that perform all checking automatically, requiring no code.
However, in this case you can create client-side code that performs essentially the same check that your server-side code is performing.
In the final part of the walkthrough, you will add some optional information to the reservation form.
You will also create a custom validator with code that you write, which illustrates how you can add your own logic to the validation framework in the page.
Finally, you will learn how you can validate user input conditionally, depending on choices that the user makes in a page.
In the walkthrough, you will create a page for a Web site that allows visitors to request a reservation.
Because the purpose of the walkthrough is to illustrate validation, the nature of the reservation is not important (for example, if could be for a restaurant, a community center meeting room, or something else), and the page does not actually process the reservation.
