Kendo网格未显示任何数据

目前,javascript应该收到数据,但它现在显示在网格中。

以下是我的* .cshtml文件中的代码,用于显示给定查询的结果:

                        <div class="col-md-6 fill-height">
                           <div class="row btn-row">
                                <div class="sxs">
                                    <button id="run-test-rule-btn" title="Test Rule">
                                    </button>
                                    <span class="button-caption">Test Rule</span>
                                </div>
                            </div>
                            <div class="row">
                                <textarea id="rule-sql" name="Rule Sql" style=""></textarea>
                            </div>
                            <div class="row fill-height">
                                <div id="query-results-grid">
                                </div>
                            </div>
                        </div>

以下是我的* .js文件中的一些代码:

var IDS = {
    queryResultsGrid: "#query-results-grid",
    ...
    runTestRuleBtn: "#run-test-rule-btn",
};
var Grids = {
    TestRuleResultsGrid: null,
    ...
};

var PageState = {
    ...
    AddingRule: false,
    TestRuleResult: null
};

function initQueryResultsGrid() {
    $(IDS.queryResultsGrid).kendoGrid({
        selectable: true,
        scrolable: true,
        sortable: false,
        columns: [
            { field: "UWI", title: "UWI", width: "100%", attributes: { tabindex: "1" } }
        ],

        change: function() {
            var selectedDataItem = this.dataItem(this.select());
            if (PageState.Selected.TestRuleResult !== selectedDataItem.TestRuleResult) {
                PageState.Selected.TestRuleResult = selectedDataItem.TestRuleResult;
                testRuleResultsSelectionChanged();
            }
        },
        editable: false
    });

    Grids.TestRuleResultsGrid = $(IDS.queryResultsGrid).data('kendoGrid');
}

function execTestRule() {
    $.ajax({
        type: 'POST',
        url: "ExecuteTestRule",
        contentType: 'application/json; charset=utf-8',
        data: JSON.stringify({
            ruleSql : PageState.SqlEditor.RuleSql.getValue(),
            parameters: PageState.RuleParameters
        }),
        success: function (matchedUwiList) {
            PageState.TestRuleResult = matchedUwiList;

            var dataSource = new kendo.data.DataSource({
                data: matchedUwiList
            });
            Grids.TestRuleResultsGrid.setDataSource(dataSource);
            PageState.Selected.ChildUwi = null;
            updateButtonStates();
        }
    });
}

以下是我的控制器中的代码:

    public ActionResult ExecuteTestRule(string ruleSql, List<PdsMatchRuleParam> parameters = null)
    {
        return Json(new MatchDataSource().ExecuteTestRule(ruleSql, parameters), JsonRequestBehavior.AllowGet);
    }

以下是我模型中的代码:

    public List<string> ExecuteTestRule(string ruleRawSql, List<MatchRuleParam> parameters)
    {
        var da = new DataAccess();
        var ruleSql = ruleRawSql.Replace(@"{KEY}", "#*$pkey");
        var dbParameters = new List<DataAccess.DbParameter>();

        dbParameters.Add(new DataAccess.DbParameter("pkey", DbType.AnsiString, 4000,
            parameters[4].DefaultValue));
        var dt = da.Select(ruleSql, dbParameters.ToArray());
        var uwis = (from DataRow r in dt.Rows
            select r["UWI"].ToString()).ToList();

        return uwis;
    }

以下是dataSource Grids.TestRuleResultsGrid.setDataSource(dataSource);中存在的数据,因此我知道它从数据库中获取了正确的数据:

matchedUwiList
["10115348", "10115348-001", "10117434-000"]

我错过了什么? TIA。

这需要处理很多,但我的第一直觉是更改您的ExecuteTestRule以返回包含UWI作为字段名称的json结果

public ActionResult ExecuteTestRule(string ruleSql, List<PdsMatchRuleParam> parameters = null)
    {
        return Json(new MatchDataSource().ExecuteTestRule(ruleSql, parameters)
            .Select(a => new {UWI = a}), JsonRequestBehavior.AllowGet);
    }

@ JamieD77有正确的想法 - 这就是我最终做的 - 添加一个匿名类型来为JSON对象提供一些结构,尽管@ JamieD77的答案更好,因为他保留了匿名对象在控制器中,我认为它是一个更好的地方:

    public object ExecuteTestRule(string ruleRawSql, List<PdsMatchRuleParam> parameters)
    {
        var da = new DataAccess();
        var ruleSql = ruleRawSql.Replace(@"{KEY}", "#*$pKey");
        var dbParameters = new List<DataAccess.DbParameter>();

        dbParameters.Add(new DataAccess.DbParameter("pKey", DbType.AnsiString, 4000,
            parameters[4].DefaultValue));
        var dt = da.Select(ruleSql, dbParameters.ToArray());
        var uwis = (from r in dt.AsEnumerable()
            select new
            {
                UWI = r.ToString()
            }).ToList();

        return uwis;
    }
