JSON没有返回任何结果

标签： asp.net json asp.net-mvc razor kendo-grid

我正在建立一个基于MVC的网站，带有一个SQL数据库＆amp; ASP.Net 4

不确定我缺少什么，但我正在尝试使用Kendo UI框架显示可更新的表。

请参阅下面的

控制器： 

/// <summary>
/// Reads the available products to provide data for the Kendo Grid
/// </summary>
/// <returns>All available products as JSON</returns>
[HttpPost]
public ActionResult Read(int take, int skip, IEnumerable<Sort> sort, Kendo.DynamicLinq.Filter filter)
{
    using (var db = new SC_NewEntities12())
    {
        var result = db.SC_Opportunities
            .OrderBy(p => p.CUST_IntranetDate_093808085) // EF requires ordered IQueryable in order to do paging
            // Use a view model to avoid serializing internal Entity Framework properties as JSON
            .Select(p => new UpdateViewModel
            {
                MANAGEUSERID = p.MANAGEUSERID,
                CUST_Customer_070539405 = p.CUST_Customer_070539405,
                CUST_Make_093929971 = p.CUST_Make_093929971,
                CUST_Model_093950750 = p.CUST_Model_093950750,
                CUST_CurrentSupplier_100623404 = p.CUST_CurrentSupplier_100623404,
                CUST_CurrentDealer_100741601 = p.CUST_CurrentDealer_100741601,
                CUST_UpdateFromSupplier_010859867 = p.CUST_UpdateFromSupplier_010859867,
                CUST_UpdateFromSupplierDate_010930291 = p.CUST_UpdateFromSupplierDate_010930291,
                CUST_CarEstimatedDeliveryDate_121235253 = p.CUST_CarEstimatedDeliveryDate_121235253,
                CUST_IntranetDate_093808085 = p.CUST_IntranetDate_093808085,
                Link2Contact = p.Link2Contact,
                Link2Opportunity = p.Link2Opportunity,
                STAGEID = p.STAGEID,
                E_Mail = p.E_Mail,
                STATUS = p.STATUS
            })
            .ToDataSourceResult(take, skip, sort, filter);

        return Json(result);
    }
}

查看 

@model IEnumerable<IntranetEF6.Models.SC_Opportunities>

@{
    ViewBag.Title = "Update JSON Test";
}

<h2>Update JSON Test</h2>

<div id="clientsDb">
    @(Html.Kendo().Grid<IntranetEF6.Models.SC_Opportunities>()

编辑：尝试修改您的操作方法以获得以下签名。您还需要使用Kendo.Mvc.UI命名空间。

    [HttpPost]
    public ActionResult Read([DataSourceRequest]DataSourceRequest dataSourceRequest)
{
 using (var db = new SC_NewEntities12())
    {
        var result = db.SC_Opportunities
            .OrderBy(p => p.CUST_IntranetDate_093808085) // EF requires ordered IQueryable in order to do paging
            // Use a view model to avoid serializing internal Entity Framework properties as JSON
            .Select(p => new UpdateViewModel
            {
                MANAGEUSERID = p.MANAGEUSERID,
                CUST_Customer_070539405 = p.CUST_Customer_070539405,
                CUST_Make_093929971 = p.CUST_Make_093929971,
                CUST_Model_093950750 = p.CUST_Model_093950750,
                CUST_CurrentSupplier_100623404 = p.CUST_CurrentSupplier_100623404,
                CUST_CurrentDealer_100741601 = p.CUST_CurrentDealer_100741601,
                CUST_UpdateFromSupplier_010859867 = p.CUST_UpdateFromSupplier_010859867,
                CUST_UpdateFromSupplierDate_010930291 = p.CUST_UpdateFromSupplierDate_010930291,
                CUST_CarEstimatedDeliveryDate_121235253 = p.CUST_CarEstimatedDeliveryDate_121235253,
                CUST_IntranetDate_093808085 = p.CUST_IntranetDate_093808085,
                Link2Contact = p.Link2Contact,
                Link2Opportunity = p.Link2Opportunity,
                STAGEID = p.STAGEID,
                E_Mail = p.E_Mail,
                STATUS = p.STATUS
            })
            .ToDataSourceResult(dataSourceRequest);

        return Json(result);
    }
}

您的操作方法仅接受HTTP POST。您的数据源配置需要如下：

   @(Html.Kendo().Grid<IntranetEF6.Models.SC_Opportunities>()
        .Name("Grid")
        .Columns(columns =>
        {
            columns.Bound(p => p.CUST_IntranetDate_093808085).Title("Intranet Date").Format("{0:dd/MM/yyyy}");
            columns.Bound(p => p.MANAGEUSERID).Title("Sales Person").ClientTemplate("#if(data.MANAGEUSERID.toString() == 'c37ac75b-286d-430a-af50-8d3dffa8b1ee') " + "{#<div>Daren</div>#} " + "if(data.MANAGEUSERID.toString() == '1acb3e5a-81ed-4cb4-a68f-094939f0efa4') " + "{#<div>David</div>#} " + "if(data.MANAGEUSERID.toString() == '739f07c5-defe-4395-a93e-51adc7f410ff') " + "{#<div>Dee</div>#} " + "if(data.MANAGEUSERID.toString() == 'ca3dfb36-0efe-43df-9801-7602a0b112ae') " + "{#<div>James</div>#} " + "if(data.MANAGEUSERID.toString() == 'a88a8884-3133-4ca5-bf82-cd4b87eb12cb') " + "{#<div>Jamie</div>#} " + "if(data.MANAGEUSERID.toString() == 'e317009f-cde0-49c2-80dc-da3ce9c40b3b') " + "{#<div>Mark</div>#} " + "if(data.MANAGEUSERID.toString() == '58d0e41d-904b-4c93-8ac7-424b5370fe2e') " + "{#<div>Paul</div>#} " + "if(data.MANAGEUSERID.toString() == '28457a43-ebc2-490f-b423-db1fdaa3d3b5') " + "{#<div>Richard</div>#} " + "if(data.MANAGEUSERID.toString() == 'c5474c7e-a829-4a0e-af07-8e0614bb3cc4') " + "{#<div>Rowan</div>#} " + "if(data.MANAGEUSERID.toString() == 'fac58484-8b20-4b97-8eb8-5d060db84d93') " + "{#<div>Russell</div>#} " + "if(data.MANAGEUSERID.toString() == 'b3fc40ae-b547-4f59-b651-ba30dbe60d1a') " + "{#<div>Sam Bryan</div>#} " + "if(data.MANAGEUSERID.toString() == '8fb9c8b4-bfe2-42ce-aa5b-d2cbbf96f186') " + "{#<div>Santi</div>#} " + "if(data.MANAGEUSERID.toString() == 'dc8cd950-d4cc-4c5f-9ab0-867dbf13d61b') " + "{#<div>Shane</div>#} " + "if(data.MANAGEUSERID.toString() == '42182f43-f8a3-41d8-bcac-70fcc9942027') " + "{#<div>Steve</div>#} " + "if(data.MANAGEUSERID.toString() == 'e93c7603-b49e-4f53-acdb-9847ba407efa') " + "{#<div>Yasir</div>#} " + "if(data.MANAGEUSERID.toString() == 'd8c83978-4aeb-49a8-8b6c-f3e5dbba4288') " + "{#<div>Jenny</div>#} " + "if(data.MANAGEUSERID.toString() == 'c48c2aec-cdf2-427b-a18b-ce6e7499fa86') " + "{#<div>Harry</div>#} " + "if(data.MANAGEUSERID.toString() == '6efc7514-d8ef-446e-85b8-0246b168d5cc') " + "{#<div>Sam Malik</div>#} #");

答案 1 :(得分：0)

我移动了kendo.aspnetmvc.min.js位于Kendo捆绑包的底部，根据其网站上的故障排除。

然后我改变了读取操作以匹配控制器的名称，而不是它;

.Read（read =＆gt; read.Action（＆＃34; Read＆＃34;，＆＃34; UpdateJSONTest＆＃34;）。输入（HttpVerbs.Post））

我感到困惑，因为剑道的样本说＆＃34; Grid＆＃34;我以为我本来是要使用网格的名称，而不是控制器。
