  Binding radio button selection to entity

  Apr 29, 2012 04:49 AM|LINK

  I have 2 radio buttons in my view:

  <input type="radio" name="gender" id="female" />Female
              <input type="radio" name="gender" id="male" />Male

  How do I get the option the user selected in my controller? I did something like

  public ActionResult GenderView(string male, string female)
          {
          }

  but those variables were always null. How do I read the selection from the controller?

  I dont get it. I guess I dont need it to bind, but maybe just get the selected value of the input from the controller, is that possible?

  when a radio button is posted, like all form elements, it sends its name & value. normal html form convention is that you woudl give the radio button the same names (to make then mutually exclusive) and give then unique values, so the server can determine which one was checked. if you folowed this convention, then in mvc for the parameter (or model property) gender, the value would be the value of the checked radio button. just add value attributes to your radio buttons.

  note: in you case as you don't supply a value, there is none posted back.
