Question

I have a view model with a foreign key to another model, base on that, I want to create a dropDownList that will show me the selected value name and will give me all the other option so I can change it to what ever I want. this is my create form:

@using (Html.BeginForm()) {
@Html.ValidationSummary(true, "Failed creating the feed")
<fieldset>
    <legend>FeedViewModel</legend>

    <div class="editor-label">
        @Html.HiddenFor(model => model.FeedId)
    </div>

    <div class="editor-label">
        @Html.LabelFor(model => model.LinkUrl)
    </div>
    <div class="editor-field">
        @Html.EditorFor(model => model.LinkUrl)
        @Html.ValidationMessageFor(model => model.LinkUrl)
    </div>

    <div class="editor-label">
        @Html.LabelFor(model => model.FolderId)
    </div>
    <div class="editor-field">

    </div>

    <p>
        <input type="submit" value="Create" />
    </p>
</fieldset>

I want to create the dropDownList at the Last div, I already have the values form my model. How can I do that?

您应该使用 Html. DropDownList 扩展方法 :

@Html.DropDownListFor(m => m.ImageId, new SelectListItem[] {
            new SelectListItem {
                Selected = true,
                Text = "Text 1",
                Value = "Fileld Value 1"
            },
            new SelectListItem {
                Selected = false,
                Text = "Text 2",
                Value = "Fileld Value 2"
            }
        });

当然第二个参数 IE 数不胜数可以从数据库而不是从硬编码中输入。
