Asp net validating date input
In HTML 3.2, validating data is a difficult process.
Each time you get a request, you need to write code to check the input and write any errors the user has made back to the page to help the user to correctly fill in the form.
However, there are times when you might want to perform validation yourself programmatically.
You might validate programmatically under these circumstances: By default, the ASP.
The different types of validators are listed as follows: Write a web page to collect a new user id and password.
The Validation Summary automatically generates this content by gathering it up from validator controls on the page. It exposes the all-important "Is Valid" property, which you check in server code to determine if all of the user input is OK.
NET Web pages automatically validate that malicious users are not attempting to send script or HTML elements to your application.
Anthony Moore Microsoft Corporation July 2000 Updated March 2002 Summary: Provides a brief overview of the validation framework in ASP.
This usually means that if you want to use script to improve the interface of your pages, you have to write the same validation logic twice, once on the client, and again on the server, just in case the client script cannot be executed.
Our objective with validation is as follows: We visited a large number of real pages to determine the sort of scenarios these components needed to be able to handle.
The password must contain 4-12 letters and at least one of the characters "@#$%^&*/." The user must re-enter the password to make sure they entered it correctly.
