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)!
waiting the reply.................
thanx in advance
Hope this clarifies.
