Question

我有一个jqGrid, 我用 asp. Net Web Form 来使用它, 它从数据库中正确显示所需的信息, 但是它也显示搜索选项, 但是如果我试图搜索, 如果说名字等于利州, 它只是没有显示记录。记录存在。我知道我错过了某些需要搜索的东西, 这里就是代码。

<script type="text/javascript">
    $(function() {
        $("#UsersGrid").jqGrid({
            url:  ModCust.ashx ,
            datatype:  json ,
            height: 250,
            width: 800,
            colNames: [ Application No ,  First Name ,  Middle Name ,  Last Name ],
            colModel: [
                        { name:  cApplicationNo , index:  cApplicationNo , width: 100, sortable: true},
                        { name:  cFirstName , width: 100, sortable: true},
                        { name:  cMiddleName , width: 100, sortable: true },
                        { name:  cLastName , width: 100, sortable: true },

                    ],

            cmTemplate: { title: false},
            rowNum: 10,
            rowList: [10, 20, 30],
            pager:  #UsersGridPager ,
            sortname:  cApplicationNo ,
            viewrecords: true,
            sortorder:  asc ,
            caption:  Customer Details 
        });

        $("#UsersGrid").jqGrid( navGrid ,  #UsersGridPager , { edit: false, add: false, del: false });
    });

    </script>

在您的问题中,您大多使用。 rel=“不跟随 nofollow noreferrer'> 演示项目 < a href=""。所有其他后来的回答都显示如何在服务器上实施高级搜索、调用和排序(例如)。

The server code which provide some interface which can be used by jqGrid to get JSON response. It can be ASP.NET MVC controller action, WFC method, WebMethod of ASMX web service or General ASHX Handler like you use.
The server code which analyse the input parameter send by jqGrid. The default names of the parameters are page, rows, sidx, sord, _search, filters. One can rename the parameters using prmNames option of jqGrid.
Access to the database. The part of the server code depends on the technology which you use. It can be for example Entity Framework, LINQ to SQL or more old but with good performance SqlCommand with SqlDataReader.
Encoding of results as JSON. One can use for example standard JavaScriptSerializer or DataContractJsonSerializer or high-performance JSON framework Json.NET (knows as Newtonsoft.JSON). Microsoft uses and supports the open source Json.NET serializer in the new version of ASP.NET MVC 4.0 and ASP.NET Web API. One can include Json.NET in the ASP.NET project and can update it to the last recent version using NuGet.
Handling on the server the exceptions and reporting the error information to the clients (jqGrid) in the JSON format. The code is a little different depend on the technology used on the server. The client code in loadError callback of jqGrid should decode the error information and display it in some form. In case of usage ASP.NET MVC I shown in the answer how to implement HandleJsonExceptionAttribute attribute which can be used as [HandleJsonException] instead of the standard [HandleError]. In case of usage WCF one can use WebFaultException<string> (see here). In case of General ASHX Handler one can use Application_Error of Global.asax for the purpose.
Optionally one can includes in the server code setting of ETag in the HTTP header. It allows to control client side cache on the server side. If the client need JSON data previously returned from the server it will automatically send If-None-Match part in the HTTP request to the server which contain ETag from the previous server response. The server can verify whether the server data are changed since the last response. At the end the server will either returns the new JSON data or an empty response which allows the client to use the data from the old response.
One need to write JavaScript code which create jqGrid.

I made the demo project which demonstrate all the above steps. It contains small Database which I fill with information about some from the famous mathematicians. The demo display the grid enter image description here where one can use sorting, paging, toolbar filtering or advanced searching. In case of some error (for example if you stop Windows Service "SQL Server (SQLEXPRESS)") you will see the error message like the following:

在演示中执行ASHX手柄的C#代码是

它使用 Newtonoft.Json 进行JSON序列序列,并将MD5大麻用作 ETag 。
