Question

我已经使用了演示代码并尝试修改它以满足我的需求，但遗憾的是我无法获得所需的结果。

树网格正在加载和“绑定”但是在扩展和折叠期间层次结构似乎存在问题（我宁愿它在默认情况下保持扩展），看起来它正在对数据进行另一个ajax请求它不应该这样做。

第一次获取数据的调用将检索所需的所有功能。

DTO：

[Serializable]
public class Company
{
    public string CompanyId { get; set; }

    public string CompnayName { get; set; }

    public bool expanded { get; set; }

    public bool isLeaf { get; set; }

    public string level { get; set; }

    public string parent { get; set; }

    public static Company FromDataReader(OracleDataReader r)
    {
        return new Company
        {
            CompanyId = r["companyid"] is DBNull ? null : r["companyid"].ToString(),
            CompnayName = r["companyname"] is DBNull ? null : r["companyname"].ToString(),
            level = r["company_level"] is DBNull ? null : r["company_level"].ToString(),
            parent = r["parent_company_id"] is DBNull ? null : r["parent_company_id"].ToString(),
            isLeaf = Convert.ToInt64(r["child_count"]) == 0 ? true : false,
            expanded = true
        };
    }

}

控制器：

[HandleJsonException]
public JsonResult CompanyService()
{
    var profiler = MiniProfiler.Current;

    using (profiler.Step("Companies"))
    {
        var q = Repository.GetCompanies(SimpleSessionPersister.User.Id).ToList();

        var result = (from c in q
                      select new string[]
                             {
                                 Convert.ToString(c.CompanyId),
                                 c.CompnayName,
                                 c.level,
                                 c.parent,
                                 Convert.ToString(c.isLeaf),
                                 Convert.ToString(c.expanded)
                             }).ToArray();

        var jsonData = new
        {
            rows = result
        };

        return Json(jsonData, JsonRequestBehavior.AllowGet);
    }


}

网格初始化：

var companyGrid;

$(document).ready(function () {
var col_names = ['CompanyId', 'Company'];
var col_model = [
                    { name: 'CompanyId', index: 'CompanyId', width: 1, hidden: true, key: true },
                    { name: 'Company', index: 'Company', width: 300, }
                ];

companyGrid = $('#treegridCompanies');

companyGrid.jqGrid({
    url: '/xxx/yyy/zzz/',
    datatype: 'json',
    ajaxGridOptions: { contentType: "application/json" },
    jsonReader: {
        id: "CompanyId",
        cell: "",
        root: function (obj) { return obj.rows; },
        page: function () { return 1; },
        total: function () { return 1; },
        records: function (obj) { return obj.rows.length; },
        repeatitems: true
    },
    colNames: col_names,
    colModel: col_model,
    height: '100%',
    rowNum: 10000,
    sortable: false,
    treeGrid: true,
    ExpandColumn: 'Company'
});

Answer 1

您在服务器部分遇到一些问题，这些问题将被转发到JSON。

第一个简单的问题是Company类。您输入了错误并使用了CompnayName而不是CompanyName。结果是代码的第一个修订版的数据无法读取CompanyName。更改为string[]和repeatitems: true后，系统会读取公司名称。

下一个问题是您忘记包含jqGrid的treeGridModel: 'adjacency'选项，输入数据将以错误的方式解释。

JSON数据中的下一个问题是您应该另外将网格的loaded列设置为true。隐藏的loaded列是expanded之后的下一列。如果您想要始终加载所有数据，可以在beforeProcessing

中解决问题

beforeProcessing: function (data) {
    var rows = data.rows, i, l = rows.length;
    for (i = 0; i < l; i++) {
        rows[i][6] = true; // set loaded column
    }
}

以同样的方式，您可以将expanded列设置为true，例如（rows[i][5] = true），您希望减少传输数据的大小。

我在JSON数据中可以看到的最后一个问题是节点顺序。您应该了解Tree Grid的工作非常简单。它会将所有行以完全相同的顺序放置在网格中，以便发布数据。可以隐藏孩子，但所有孩子必须直接在其父节点之后。因此，您应该更改服务器响应中放置的数据的顺序。

如何将jqGrid（4.x）配置为TreeView
