Question

我正在使用ASP.NET MVC，我有一个View，在HttpPost操作中检索哪些表单数据。调用HttpPost操作时，它工作正常。我使用表单数据来查询数据库，并将数据库中的结果绑定到TELERIK Grid控件。它显示数据正常，但分页不起作用。

问题在于，当我尝试切换到另一个页面时，它会调用HTTPGET操作方法而不是HttpPost操作方法，因此不会从数据库中检索数据。

感谢任何帮助。

以下是视图和控制器的代码：

//-------------View------------------------------------

@(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);
                dataBinding.Ajax().Select("DealerProfile", "DealerManagement", new { testVal = "test" } ).Enabled(true);
            })

            .Pageable(paging =>
                paging.PageSize(20)
                      .Style(GridPagerStyles.NextPreviousAndNumeric)
                      .Position(GridPagerPosition.Bottom)
            )
            .Filterable(filtering => filtering.Enabled(true))
            .Groupable(grouping => grouping.Enabled(true))
            .Footer(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。您可以查看ajax binding help article以及显示所需步骤的ajax binding online demo。很可能你应该为ajax绑定定义一个单独的动作方法。

最后，似乎网格的JavaScript没有启动 - 它正在发出HTTP GET请求表明这一点。检查在网格之后是否声明了ScriptRegistrar组件。
