ASP.NET VALIDATION (Client verse Server)

I am having some trouble understanding what the ASP.NET validation controls actually do.

Do they validate on the client, the server, or both?

I understand the customvalidator has an event called onServerValidate which can be used to trigger server validation.  

But what about the requiredfieldvalidator, rangevalidator, etc, etc.  There is a setting that says EnableClientScript.  I have set this to false and have mixed results.  In some cases the validation doesn't work anymore and in other cases it works fine.  

I don't know if I should be creating client and server side validation routines.  If so, how do I do both at the same time?

ASP.Net Validation controls generate client side JavaScript, when the 'EnableClientScript' is set to true the script is in an .js file located at

http://localhost/...SiteName.../aspnet_client/system_web/1_1_4322/WebUIValidation.js

Most all users have Javascript enabled to you should be safe using the 'EnableClientScript'. This way, when the user presses the 'submit' button, validation takes place immedaitly on the clients machine, otherwise a round trip to the server is made, possibly just to send the page back with some red ink telling the user that a field value is incorrect.

The best practice I've found is to use the ValidationControls with the client script. And also write some server based code to double check the values, if they don't look write you can take the appropraite action.

You do not need to 'create client and server' validation routines.  Just create the 'validation' routine, as is, and ASP.NET will take care of what is needed.  (actually, the validation is 'normally' done on BOTH sides - using the same code, as provided by you).
