JqGrid 编辑功能在我的网格中运行良好，但删除功能始终将记录 ID 传递为 0。
@model Shop.Models.ShopModels.lstMainCategory
<table id="list" class="scroll" cellpadding="0" cellspacing="0"></table>
<div id="pager" class="scroll" style="text-align:center;"></div>
<script type="text/javascript">
var myGrid = $('#list');
$(document).ready(function () {
$.jgrid.nav.addtext = "Add";

$.jgrid.del.caption = "Delete Main Category";

$.extend($.jgrid.edit, {

$(this).jqGrid("setGridParam", { datatype: "json" });
return [true, "", ""];

控制器：
public ActionResult Update(lstMainCategory viewModel, FormCollection formCollection)
{
var operation = formCollection["oper"];
lstMainCategory mcat = new lstMainCategory();
rep = new MaincategoryRepository();
if (operation.Equals("add"))
{
mcat.MainCategoryName = viewModel.MainCategoryName;
rep.Create(mcat);
rep.Save();
}
else if (operation.Equals("edit"))

mcat.MainCategoryName = viewModel.MainCategoryName;
rep.Edit(mcat);
rep.Save();
}
else if (operation.Equals("del"))
{
rep.Delete(viewModel.MaincategoryID);//here MaincategoryID is always 0 so it's not working
rep.Save();
}
return Content("true");
}
