Question

在我看来,我试图利用从名单上删除的作者(用户)名单。我能够把这一下降集中起来,并看到我的看法的内容。我在提交我的表格时,在我的控制员中和在检查我的模型时,我不敢行动,与我的下降有关的实地价值就是无效的。

Here is my action controller (before showing my view):

    public ActionResult Create()
    {
        IEnumerable<User> authors = m_AccountBusiness.GetAllUsers();

        PageCreateViewModel viewModel = new PageCreateViewModel
        {
            PageToCreate = new PageFullViewModel(),
            Authors = authors.Select(x => new SelectListItem { Text = x.UserName, Value = x.UserID.ToString() })
        };

        return View(viewModel);
    }

下面是(部分)我的看法:

@model MyBlog.ViewModels.PageCreateViewModel

<h3>Create</h3>

@using (Html.BeginForm())
{

@Html.ValidationSummary(true)
@Html.HiddenFor(model => model.PageToCreate.PageID)

<div class="editor-label">
    @Html.LabelFor(model => model.PageToCreate.Title)
</div>
<div class="editor-field">
    @Html.TextBoxFor(model => model.PageToCreate.Title, new { @class = "titleValue" })
    @Html.ValidationMessageFor(model => model.PageToCreate.Title)
</div>

<div class="editor-label">  
    @Html.LabelFor(model => model.PageToCreate.Author)
</div>
<div class="editor-field">      
    @Html.DropDownListFor(model => model.PageToCreate.Author, Model.Authors, "Please select...")    
</div>

我的《意见》是:

public class PageCreateViewModel
{
    public PageFullViewModel PageToCreate { get; set; }
    public IEnumerable<SelectListItem> Authors { get; set; }
}

任何想法?

感谢。

谢谢。最后,我发现我的错误:没有。作者是受约束的权利财产,必须成为作者!

<div class="editor-field">           
@Html.DropDownListFor(model => model.PageToCreate.AuthorID, Model.Authors, "Please select...")         
</div>

感谢。

You have to add an extra string property to your PageCreateViewModel. In this property we will store the selected value. Lets say it s name is "Author". Edit: I noticed you have a property for it in your model but give it a try like this.

填补下游名单需要考虑您的看法。

 @Html.DropDownList("Author", Model.Authors)
