Telerik Grid 数据绑定调用 HttpPost 方法

Question

我正在开发 ASP.NET MVC，并且有一个在 HttpPost 操作中检索表单数据的视图。当调用 HttpPost 操作时它工作正常。我使用表单数据查询数据库，并将数据库的结果绑定到 TELERIK 网格控件。它可以正常显示数据，但分页不起作用。

问题是，当我尝试切换到另一个页面时，它调用 HTTPGET 操作方法而不是 HttpPost 操作方法，因此不会从数据库检索数据。

任何帮助表示赞赏。

这是视图和控制器的代码：

@(Html.Telerik().Grid(Model)
            .Name("Grid")
            .Columns(columns =>
            {
                columns.Bound(o => o.DealerName);
                columns.Bound(o => o.DealerNumber);
                columns.Bound(o => o.ServiceDealerNumber);
                columns.Bound(o => o.CMDealerNumber);
                columns.Bound(o => o.PurchaseDealerNumber);
                columns.Bound(o => o.Address);
                columns.Bound(o => o.City);
                columns.Bound(o => o.State);
                columns.Bound(o => o.Zip);
            })
            .DataBinding(dataBinding =>
            {
                dataBinding.Server().Select("DealerProfile", "DealerManagement", new { testVal = "test" }).Enabled(true);

                      .Style(GridPagerStyles.NextPreviousAndNumeric)
                      .Position(GridPagerPosition.Bottom)
            )
            .Filterable(filtering => filtering.Enabled(true))
            .Groupable(grouping => grouping.Enabled(true))

首先，您的控制器方法需要 GridAction 属性。其次，它必须使用 GridModel 类型作为模型。这是 ajax 绑定所必需的。您可以检查 ajax绑定帮助文章 以及 ajax 绑定在线演示，其中显示了需要什么步骤 是。最有可能的是，您应该为 ajax 绑定定义一个单独的操作方法。

最后，网格的 JavaScript 似乎没有启动——它发出 HTTP GET 请求的事实表明了这一点。检查网格之后是否声明了 ScriptRegistrar 组件。
