推荐答案

看看这个

mvc dropdownlist binding [ ^ ]

1。我们在BindingDropDown方法中创建了一个 SelectListItems 列表，并将其传递给View。把它扔到了View。

1. We have created a list of SelectListItems inside the "BindingDropDown" method and passed it to the View. ssed it to the View.

List<SelectListItem> items = new List<SelectListItem>();
items.Add(new SelectListItem
{
    Text = "item1",
    Value = "1"               
});
items.Add(new SelectListItem
{
    Text = "item2",
    Value = "2"                
});

ViewData["ListItems"] = items;//This will be used to bind to Dropdownlist

绑定下拉视图



a。我们可以使用html.Dropdownlist绑定下拉列表（它是一个HTML帮助类）。

Binding Drop down at View

a. We can bind the dropdown list using html.Dropdownlist (it is a HTML helper class).

ListItems: <%= Html.DropDownList("ListItems")%>

这里我们传递从控制器传递到视图的ListItems。



b。 html.DropdownList类的另一个重载方法，用于绑定下拉列表。

Here we are passing "ListItems" that has been passed from the controller to the view.

b. Another overloaded method of the html.DropdownList class for binding a dropdown list.

<%= Html.DropDownList("SelectedItem", (IEnumerable<SelectListItem>)ViewData["ListItems"])%>

运行后，您将获得包含2个项目的下拉列表

After run, u will get dropdown list with 2 items
