When to use client side varidation and server side varidation in .net?
In .net or classic web application we can varidate user data either on client isde or server side. How to select which side varidate to be used? Thanks!
Generally, I use both client and server validation. I make sure the input is in the correct format and reasonably valid on the client, then I verify the data on the server. The extent of validation also depends on the type of data that I need to validate.Here are a few references:Validating ASP.NET Server ControlsIntroduction to Validating User Input in Web FormsClient-Side Validation for ASP.NET Server ControlsSecurity Checklist...When To Use Client Side vs Server Side vs AJAX
Before AJAX, it was fairly clear to me where to draw the line between functionality best performed server-side vs client-side. For example, database access and data processing is done on the server, and basic field validation and other UI stuff is done on the client.

Please can someone tell me when do i need to use a client-side or a server-side?
For instance, I have a dropdownlist and when the user choses one of the listitems then click on the button to submit changes,i need first to validate the new value chosen by the user by comparing it with the old value and then redirect the user to the next page if there are no errors or view an error on the other hand! so in this case what's more preferable to use a JScript (client side) or on the click event of the button pressed (server side)!
