validation in asp.net

http://www.w3schools.com/aspnet/aspnet_refvalidationcontrols.asp[^]

check this link for the best validation in ASP.NET

What do you mean by best procedure? check this article to understand client side and server side validation

Micro$oft provide an example here[^]. I usually find following the advice of the vendor of a product is a good idea.

Further advice can be found in these links[^]

Vague question.There is no such Best Procedure.

Validation can be done in two ways (client side or server side)
choosing client side or server side validation totally depends on the scenario

the above's are some example.Try to avoid vs studio built in 6 validation control,u have to create validation in java script,jquery,use web service for validation.

Depends on the validation you're trying to solve, whether you want to do it client-side of server-side, what kind of controls you're using, ...

There is no "best" for all situations.

Go for client side validation. You can use JavaScript or ASP.NET Validation Controls.

You can validate at Server side as well. So, depends upon you.

the best solution depends mainly on what is your requirement. Either you want client side validation or server side.

RequiredFieldValidators, Regular Expressions, JavaScript, jQuery and alot of other solutions can be tried.

But let's have a look on what I have been using and pretty satisfied with.

JQUERY Validation Engine

its a JQUERY plugin which is easy to embed and pretty awesome.


Hope it will help. :)
