在ASP.NET MVC中构建视图时，强类型HTML helpers非常有用。像@Html.TextBoxFor(m => m.FirstName)这样内置的Helper方法已经存在很长时间了，它们提供诸如视图编译时间检查、Razor支持等优点，并支持使用数据注释来自动配置重要的选项，如验证规则。 自从我们发布DevExtreme ASP.NET MVC控件以来，它们已经包含了一套HTML helper方法来帮助您完成设置DevExtreme编辑器的工作。 例如在这里，我们创建一个DevExtreme MVC DateBox控件，该控件将从模型绑定到OrderDate字段中： @Html.DevExtreme().DateBoxFor(m => m.OrderDate) 更多的Lambda表达式 在下一个主要版本v17.2中，我们扩展了在HTML helpers中使用表达式的功能。已经添加了更多的lambda表达式到更多的小部件中，这允许使用它们来配置项目，如： DataGrid and TreeList columns DataGrid summaries PivotGrid fields Items of our Form control 因此，DataGrid控件现在可以使用以下语法来声明： 1 2 3 4 5 6 7 8 9 10 11 12 @(Html

I would like to know how to properly add a unbound column into a gridview. I've added a unbound column in the designer (set the unbound type, display format and all) but whenever I run the application, try to change the value of the unbound column and loses its focus the value is not saved (even the display format is not displaying correctly when I'm changing it). I must be doing something wrong. I need help guys! Much appreciated! Unbound column does not provide a storage to save its values. Instead, the GridView publishes the CustomUnboundColumnData event which can be used to provide data to
