For production applications, developers often end up spending a lot more time and code on this task than we would like. NET page framework, it was important to try and make the task of validating input a lot easer than it has been in the past.
For example, if you want to check whether or not user input in a text box is (a) nonblank, (b) a valid date between a particular range and (c) less than the date in another text input control, you would want to use three validators.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.We wanted to dramatically reduce the amount of validation code needed for future applications.Anthony Moore Microsoft Corporation July 2000 Updated March 2002 Summary: Provides a brief overview of the validation framework in ASP.NET and walks through an example of adding validation to a page.The user id must contain 6-10 alpha characters and must not already be in use.
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.Starting page: The first thing we need to enforce is that the fields get filled in at all.In front of each field, we add a Required Field Validator.However, it can be almost impossible to guarantee that every user of your site has the required scripting environment.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.The final step is to add a validation summary to the top of the page like so: Here is how it looks on the page: Next we need to enforce the character requirements for the User ID and Password fields.
