Jqgrid transmits JSON parameters to the Controller

After serializeeditdata, the parameter cannot be obtained in the Controller. It is always null.

Later, the extended modelbinder method was used.

It was strange that the binding failed. later it was found that controllercontext. httpcontext. Request. Form [bindingcontext. modelname] was empty. You cannot use controllercontext. httpcontext. Request. Form [0] to catch up with the progress.
