Question

我刚刚开始学习Kendo UI MVC并且遇到了以下问题。这是我的代码：

@(Html.Kendo().Grid<JeffreysOnline.Entities.Customer>()
    .Name("grid")
    .Columns(columns =>
    {
        columns.Bound(p => p.FirstName);
        columns.Bound(p => p.LastName);
        columns.Bound(p => p.Address);
        columns.Command(command => { command.Edit(); command.Destroy(); }).Width(250);
    })
    .ToolBar(toolbar => toolbar.Create())
    .Editable(editable => editable.Mode(GridEditMode.InLine))
    .Pageable()
    .Sortable()
    .Scrollable()
    .HtmlAttributes(new { style = "height:550px;" })
    .DataSource(dataSource => dataSource
        .Ajax()
        .PageSize(20)
        .Events(events => events.Error("error_handler"))
        .Model(model => model.Id(p => p.ProductID))
        .Create(update => update.Action("EditingInline_Create", "Grid"))
        .Read(read => read.Action("EditingInline_Read", "Grid"))
        .Update(update => update.Action("EditingInline_Update", "Grid"))
        .Destroy(update => update.Action("EditingInline_Destroy", "Grid"))
    )
)

我收到以下错误，第23行突出显示。

Compiler Error Message: CS1660: Cannot convert lambda expression to type 'string' because it is not a delegate type

Line 21:     .Scrollable()
Line 22:     .HtmlAttributes(new { style = "height:550px;" })
Line 23:     .DataSource(dataSource => dataSource
Line 24:         .Ajax()
Line 25:         .PageSize(20)

它似乎不喜欢数据源＆＃39;但我不知道它会期待什么。

如果ProductId不是您模型的属性，则可能导致错误。

您似乎直接从telerik的内联编辑教程页面中获取了示例：http://demos.telerik.com/aspnet-mvc/grid/editing-inline，因此请尝试在数据源中调整指向模型的列。像这样：

 .DataSource(dataSource => dataSource
        .Ajax()
        .PageSize(20)
        .Events(events => events.Error("error_handler"))
        .Model(model => model.Id(p => p.RandyMindersActualIdColumnProperty)) // Here is the change
        .Create(update => update.Action("EditingInline_Create", "Grid"))
        .Read(read => read.Action("EditingInline_Read", "Grid"))
        .Update(update => update.Action("EditingInline_Update", "Grid"))
        .Destroy(update => update.Action("EditingInline_Destroy", "Grid"))
    )
