Validating forms in asp
This tutorial will explain how to correctly use the Validation server controls built into the .
NET Framework to validate user input on your pages.
It's also very precise, as you can point out the exact field where there's a problem.We're going to be checking the form using a function, which will be activated by the form's and the data will be submitted. It's impossible for me to give you a definitive validation script, as every form is different, with a different structure and different values to check for.A Java Script check is useful because it stops the form from being submitted if there is a problem, saving lots of time for your readers.The CGI script is still more reliable, as it always works regardless of whether Java Script is enabled on the client-side or not; but having this extra safety barrier is a nice thing to have in place.
These can be used for submitting different sets of validated fields separate from other sets of validated fields whilst only validating the set of fields being submitted.I live in Perth, Scotland and am senior programmer with Web Xe Ltd.
