Is it possible to change values on the screen and send them to the server?

Work in an Asp.Net application where some values such as order prices and products are collected from the form. The final total of the request is made on the sum of the values coming from the form, the text / value property.

My question is that if some system user can for example change these values in the HTML that he has access by the browser and send divergent values for processing.

If your question is more conceptual, the answer will be yes , you can change the price values of the orders and / or products and / or the total in the HTML. For this reason, it is always recommended to do the validations both on the client side and on the server side.

In this link you will find the dangers of validation on the client side only.
