Answer 1

You have a few options.

On the model add this attribute to each property that you need to allow HTML - best choice

[AllowHtml]

On the controller action add this attribute to allow all HTML

[ValidateInput(false)]

Hi,

 

Add ValidateRequest = "false" in your code.

 

Web Config :

<configuration>
  <system.web>
   <httpRuntime requestValidationMode="2.0" />
  </system.web>
  <pages validateRequest="false">
  </pages>
</configuration>

Reference Code : 

[HttpPost]
[ValidateInput(false)]
public ActionResult MyMethod(string s)
{
    ....
}
