Asp.net form validation feature is to prevent malicious content such as html, js in http requests.

When the business needs to allow such content to be entered, you can do the following settings:

1. Turn off the validation of the form ([ValidateInput(false)])



2. Set a form attribute separately without validation ([AllowHtml])



3. When using Rquest.Form (Unvalidated)



Also, note that there is a configuration premise in web.config

AllowHtmlAttribute Class


Allows a request to include HTML markup during model binding by skipping request validation for the property. (It is strongly recommended that your application explicitly check all models where you disable request validation in order to prevent script exploits.)
