Data Validations

Question

Hi Where should the Data Validations be performed at the client side or at the server side and why ?

MuthuMari M · Answer

HI Data validations should be done primarily at the client side and the server-side validation should be avoided because it makes server task overloaded. If the client-side validation is not available you can use server-side validation. When a user sends a request to the server the validation controls are invoked to check the user input one by one. thanks. If this post is useful then mark it as  Accepted Answer

Hi Arun All user input data validation should occur on the server at a minimum. Additionally client-side validation can be performed where deemed appropriate and feasable to provide a richer more responsive experience for the user.
