Question

我正在尝试在我的应用程序中实现jQGrid一些基本功能，包括过滤和子网格。我看了很多文章，但其中许多似乎已经过时了。我想我正在努力实现它的基础知识。如果您可以提供基本的控制器视图结构或从头开始参考任何类型的教程asp. net mvc 3.

，我将非常感激。

以下是View中的代码（首先是标记，然后是JS）：

@model SampleApp.SampleModel

@{
    ViewBag.Title = "Stackoverflow Title";
    Layout = "~/Views/Shared/_defaultLayout.cshtml";

}

<link href="@Url.Content("~/Content/themes/cupertino/jquery-ui-1.8.13.custom.css")" rel="stylesheet" type="text/css" />
<link href="@Url.Content("~/Content/grid/ui.jqgrid.css")" rel="stylesheet" type="text/css" />
<script src="@Url.Content("~/Scripts/ui/jquery-ui-1.8.12.custom.js")" type="text/javascript"></script>
<script src="@Url.Content("~/Scripts/grid/grid.locale-en.js")" type="text/javascript"></script>
<script src="@Url.Content("~/Scripts/grid/jquery.jqGrid.min.js")" type="text/javascript"></script>
<script src="@Url.Content("~/Scripts/myJSHelper.js")" type="text/javascript"></script>

<script type="text/javascript" id="loadGridResultsScript1">
    // This code LOADs the grid by calling the MVC Action to get Data
    $(document).ready(function () { helper.loadSearchResults('@Model.JobCode'); });
</script>

<!-- these are the jQuery Grid controls -->
<table id="list" class="scroll" cellpadding="0" cellspacing="0"></table>
<div id="pager" class="scroll" style="text-align:center;"></div>

以下是myHelper JS文件中的JS函数：

loadSearchResults: function (id) {

        $("#list").jqGrid({
            url: vpath + '/Sample/GetTargets/' + id,
            datatype: 'json', mtype: 'POST', colNames: cols,
            colModel: colModel, pager: $('#pager'),
            rowNum: 15, rowList: [5, 10, 15, 25, 50, 100], sortname: cols[1],
            sortorder: "asc", viewrecords: true,
            imgpath: '', caption: ' '
        });
        $("#list").setGridWidth(1000, true);
        $("#list").setGridHeight(350, true);


    }

这里是jQuery调用的Action：

        public ActionResult GetTargets(string id, string sidx, string sord, int page, int rows)
    {

        var repo = IOCContainer.Resolve<DataRepository>();
        ////////////////////////////////////////////////////////////////////
        var job = svc.GetJobByCode(id);
        // job is my 'Model', it is a System.Data.DataSet

        int pageIndex = Convert.ToInt32(page) - 1;
        int pageSize = rows;

        int totalRecords = (job.Targets == null) ? 0 : job.Tables[0].Rows.Count; 
        int totalPages = (int)Math.Ceiling((float)totalRecords / (float)pageSize);
        List<DataRow> pageSet = Enumerable.Empty<DataRow>().ToList();

        if (totalRecords > 0)
        {
            // Get rows for current page!!!
            if (sord == "asc")
            {
                if (sidx == "   ") sidx = job.Tables[0].Columns[0].ColumnName;

                pageSet = job.Tables[0].Rows.Cast<DataRow>()
                        .OrderBy(q => q[sidx])
                        .Skip(pageIndex * pageSize)
                        .Take(pageSize)
                        .ToList();
            }
            else
                pageSet = job.Targets.Tables[0].Rows.Cast<DataRow>()
                        .OrderBy(q => q[sidx])
                        .Reverse()
                        .Skip(pageIndex * pageSize)
                        .Take(pageSize)
                        .ToList();
        }

        var cols = GetColumnNames(job.Tables[0]);
        // Func to get Cells, called later on in code...
        Func<DataRow, string[], string[]> getCells = (pkg, columns) =>
        {
            var cellList = new List<string>();
            cellList.Add(pkg[0].ToString());
            foreach (var col in columns)
            {
                if (col.StartsWith("_")) continue;
                object cellContent = pkg[col];
                string cellText = string.Empty;
                if (cellContent is DateTime)
                {
                    cellText = ((DateTime)cellContent).ToString("MM/dd/yyyy");
                }
                else if (cellContent is decimal || cellContent is double)
                {
                    cellText = string.Format("{0:c}", cellContent);
                }
                else
                {
                    cellText = String.Format("{0}", cellContent);
                }
                cellList.Add(cellText);
            }

            return cellList.ToArray();
        };
        var jsonData = new
        {
            total = totalPages,
            page,
            records = totalRecords,
            rows = (
                from item in pageSet
                select new
                {
                    i = item[0].ToString(),
                    cell = getCells(item, cols)
                }).ToArray()
        };
        return Json(jsonData);
    }

我希望你觉得这很有帮助。如果有任何问题，请告诉我
