jqGrid：布局坏了吗？

Question

我在Dialog中使用jqgrid，但看起来布局坏了：

1. 底部网格的搜索按钮出现两次？
2. 字体太大。

当我将网格显示为普通视图时，没有问题。

index.cshtml打开弹出窗口：

<div id="btnGo">
    <img id="UserProfileLookUp" src="../../Content/images/ui-flag_blue.png" />
</div>
<script>
    $(document).ready(function () {
        $('#btnGo').click(function () {
            $("#Dialog").dialog("open");
        });
        $("#Dialog").dialog({
            modal: true,
            autoOpen: false,
            height: 413,
            width: 626
        });
    }); 
</script>
<div id="Dialog" title="Product Select" style="display: none;">
    @{Html.RenderAction("Test", "Home");}
</div>

实际的jqgrid：

<link href="@Url.Content("~/Content/site.css")" rel="stylesheet" type="text/css" />
<link href="@Url.Content("~/Content/themes/base/jquery-ui.css")" rel="stylesheet" type="text/css" />
<link href="@Url.Content("~/Content/jqGrid/jquery-ui-jqgrid.css")" rel="stylesheet" type="text/css" />
@{ ViewBag.Title = "jqGrid in ASP.NET MVC - Searching [Advanced]"; }
<table id="jqgProducts" cellpadding="0" cellspacing="0">
</table>
<div id="jqgpProducts" style="text-align: center;">
</div>
<div id="dlgSupplier">
</div>
<script id="tmplSupplier" type="text/x-jquery-tmpl">
        ${CompanyName}<br /><br />
        ${Address}<br />
        ${PostalCode}, ${City}<br />
        ${Country}<br /><br />
        ${Phone}<br />
        ${HomePage}
</script>
<script type="text/javascript">
        $(document).ready(function () {

            $('#jqgProducts').jqGrid({

控制器：

public ActionResult Index()
{
   return View();
}

public ActionResult Test()
{
  return PartialView();
