Xmlinputfactory is validating
After you determine that something was entered, you can then also check to see whether what was entered is a number or a character and if it is in the correct format.
When you used server-side validation with ASP 3.0, if something the user entered was wrong, you could repost the form and ask the user to correct the information in that particular field of the form.
Sometimes, you carried the correct input from the other fields back to the form page, and populated the fields for the users so they didn't have to re-enter the same information again.
These forms are made up of different types of HTML elements that are constructed using straight HTML, HTML server controls, or Web server controls.
A variety of HTML elements, such as text boxes, check boxes, radio buttons, drop-down lists and more, can be used in forms. NET applications are collecting information from a user, you want to ensure that the data that you collect is valid.
This paper introduces these new controls and discusses tips and tricks on working with them in practical scenarios.
If the data is incorrect or not valid, you can send back a response stating this.
You ensure this by eliminating any chance that the information collected does not abide by the rules you outline. NET don't know the difference between client-side and server-side validation.Validation server controls are a series of controls that help you validate the data that the user enters into the other controls that are provided with ASP. They determine whether the form can be processed based upon the rules that you define in the validation server controls.One of the most common elements of Web pages is a form in which the user can input data that is posted back to the server.From there, you can compare user input in different fields or against values that might be held in other repositories, such as a database.You can check for many types of information, as you learn in the rest of this article.Validation is testing to determine whether the user entered into the field.
