如何将 KendoUI DropDownListFor 绑定到 ViewData 或 ViewBag? [英] How to bind KendoUI DropDownListFor to ViewData or ViewBag?

问题描述

我正在尝试将 KendoUI DropDownListFor 用于我的模型外键并将其与 ViewData/ViewBag 完整列表绑定，但似乎无法工作，我是否遗漏了什么?

I'm trying to use KendoUI DropDownListFor for my model foreignkey and bind it with ViewData/ViewBag complete list but can't seems to work, am i missing something?

@(Html.DropDownListFor(model => model.Hotel.HotelStatusId, ViewData["HotelStatuses"] as SelectList))

这似乎有效，但需要我创建一个视图模型.

This seems to work but required me to create a viewmodel.

@(Html.Kendo().DropDownListFor(model => model.Hotel.HotelStatusId)
                              .BindTo(Model.HotelStatuses)
                              .OptionLabel("select hotel status...")
                              )

我避免使用视图模型，因为我需要将数据提交回 ASP MVC.使用自定义视图模型，我无法正确绑定它.

I'm avoiding using viewmodel because i need to submit the data back to ASP MVC. With the custom viewmodel, i couldn't bind it correctly.

推荐答案

Viewbag/ViewData 在控制器中可以这样填充:

Viewbag/ViewData can be filled like this in controller:

ViewData["HotelStatuses"] = 
new SelectList(db.HotelStatuses, "HotelStatusId", "HotelStatusText");

在视图中你可以使用 ViewData/ViewBag:

And in view you can use ViewData/ViewBag:

 @(Html.Kendo().DropDownListFor(model => model.Hotel.HotelStatusId)
 .BindTo(ViewData["HotelStatuses"] as SelectList))
 .DataTextField("Text")
