我正在开发一个 MVC3/razor 应用程序，我正在尝试使用 subGridRowExpanded 将 jqGrid 嵌套在另一个内部（因此我可以使用格式化程序等），如何将父网格的 id 值传递给子网格网格？

下面的代码运行主网格，并使用“搜索/客户”URL 中的数据填充它，但我不知道如何选择我在“搜索/银行链接”URL 控制器中选择的记录

谁能告诉我该怎么做？

在此先感谢安德鲁。

我的索引.cshtml

@{
    ViewBag.Title = "Index";
}

<h2>@ViewBag.Message</h2>
<div id="content">
    <div id="content-left">
        @Html.Partial("SearchPanel")
    </div>
    <div id="content-main">
        <table id="jpgCustomers" cellpadding="0" cellspacing="0"></table>
        <div id="jpgpCustomers" style="text-align:center;"></div>
    </div>
</div>
@section JavaScript
{
<script type="text/javascript">
    $(document).ready(function ()

            },
        });
    });

我的控制器操作：

顾客

[AcceptVerbs(HttpVerbs.Post)]
public ActionResult Customers(JqGridRequest request)
{
    ISession session = NHibernateHelper.GetCurrentSession();
    IEnumerable<Customer> customers = session.QueryOver<Customer>().List().Skip<Customer>(0).Take<Customer>(request.RecordsCount);

    int totalRecords = customers.Count();

    //Prepare JqGridData instance
    JqGridResponse response = new JqGridResponse()
    {
        //Total pages count
        TotalPagesCount = (int)Math.Ceiling((float)totalRecords / (float)request.RecordsCount),
        //Page number
        PageIndex = request.PageIndex,
        //Total records count
        TotalRecordsCount = totalRecords
    };
    //Table with rows data
    foreach (Customer customer in customers)
    {
        response.Records.Add(new JqGridRecord(Convert.ToString(customer.Id), new List<object>()
        {
            customer.FtpDetails.LogonName,
            customer.FtpDetails.FullName,
            customer.FtpDetails.Enabled,
            customer.IsTran
        }));
    }

    //Return data as json
    return new JqGridJsonResult() { Data = response };
}

银行链接

[AcceptVerbs(HttpVerbs.Post)]
public ActionResult BankLinks(JqGridRequest request)
{
    ISession session = NHibernateHelper.GetCurrentSession();

    //IN THIS LINE I HAVE HARDCODED value 14 - I need this value to be passed from the 
    //Parent Grid!
    Customer customer = session.Get<Customer>(14);

    int totalRecords = customer.Banks.Count();

    //Prepare JqGridData instance
    JqGridResponse response = new JqGridResponse()
    {
        //Total pages count
        TotalPagesCount = (int)Math.Ceiling((float)totalRecords / (float)request.RecordsCount),
        //Page number
        PageIndex = request.PageIndex,
        //Total records count
        TotalRecordsCount = totalRecords
    };

    foreach (Bank bank in customer.Banks.ToList<Bank>())
    {
        CustomerBank bankLink = session.QueryOver<CustomerBank>().Where(x => x.BankId == bank.Id).Where(y => y.CustomerId == customer.Id).List<CustomerBank>().FirstOrDefault();

        response.Records.Add(new JqGridRecord(null, new List<object>()
        {
            bank.BankCode,
            bank.Folder,
            bankLink.Enabled 
        }));
    }
     return new JqGridJsonResult() { Data = response };
 }

首先你应该subGridRowExpanded像这样修改你的回调：

subGridRowExpanded: function(subgrid_id, row_id) {
    var subgrid_table_id, pager_id;
    subgrid_table_id = subgrid_id + '_t';
    pager_id = "p_"+subgrid_table_id;
    $('#' + subgrid_id).html('<table id="' + subgrid_table_id + '" class="scroll"></table><div id="' + pager_id + '" class="scroll"></div>');
    $('#' + subgrid_table_id).jqGrid({
        url: encodeURI('@Url.Action("BankLinks")' + '?id=' + row_id),
        datatype: 'json',
        mtype: 'POST',
        colNames: ['Bank', 'Folder', 'Enabled'],
        colModel: [
            {name: 'Bank', index: 'Bank', width:80, key:true },
            {name: 'Folder', index:'Folder', width:130 },
            {name: 'Enabled', index: 'Enabled', width:70, align: 'left' }
        ],
        rowNum: 20,
        pager: pager_id,
        sortname: 'Bank',
        sortorder: 'asc',
        viewrecords: true,
        height: '100%'
    });
    $('#' + subgrid_table_id).jqGrid('navGrid', '#' + pager_id, {edit: false, add: false, del: false })
}

请注意使用encodeURI以确保生成的 URL 有效。

现在您可以像这样修改您的操作方法：

[AcceptVerbs(HttpVerbs.Post)]
public ActionResult BankLinks(int id, JqGridRequest request)
{
    //You can sue id parameter to get the data for selected client.
    ...
}

这应该可以解决问题。
