Asp.net mvc send parameter to action with submit button in the partialView

问题

My partialView is Opened in the modal dialog form, User select special row, I want to Submit the parent form with special value as a parameter.

My parent form is:

<form id="mainForm" action="<%= Request.RawUrl %>" method="post" enctype="multipart/form-data">

and my submit button in the modal dialog (and in the GridView) that post data to action is:

<button name="selectVehicle" id="<%= item.id %>" value="selection" type="button" onclick="$('#mainForm').submit()">
                    OK
                </button>

this is work correctly and all my data Post to the Action, but how can i send special Value to the action using this submit button?
