Question

我正在尝试让我的网格更新为选择加入状态，但是当我点击更新时，不会发生任何操作。我使用ajax绑定模型和实体框架。当我点击取消时，它将遵循此方法。因为其他所有功能和编译，我不确定我错过了什么。

<div class="row">
<h2>PQA Opt-In</h2>

 @(Html.Kendo().Grid<TelerikMvcApp1.Models.PQAViewModel>()
    .Name("grid")

    {
        columns.Bound(opt => opt.Jobber).Width(90);
        columns.Bound(opt => opt.Dealer).Width(95);

您已将所有列都设为不可编辑 - 这意味着您不会对模型进行任何更改。如果没有进行任何更改 - 则不会执行更新请求。对模型进行更改并触发更新。
