ASP.NET MVC 2 - ViewModel前缀

Question

我希望在我的视图中使用RenderPartial两次,并关联不同的模型.问题是两个模型中都存在一些属性(昵称,密码).它们没有前缀,所以即使id或名称在输出中也是相同的.现在,如果我有昵称或密码的模型错误,则两个字段都会突出显示.

主要观点:

<div>
    <% Html.RenderPartial("Register", Model.RegisterModel); %>
</div>
<div>
    <% Html.RenderPartial("Login", Model.LoginModel); %>
</div>

登录PartialView:

<% using (Html.BeginForm("Login", "Member")) { %>
<fieldset>
    <legend>Login</legend>
    <p>
        <%= Html.LabelFor(x => x.Nickname) %>
        <%= Html.TextBoxFor(x => x.Nickname) %>
    </p>
    <p>
        <%= Html.LabelFor(x => x.Password) %>
        <%= Html.PasswordFor(x => x.Password) %>
    </p>    
    <input type="submit" value="Login" />
</fieldset>
<% } %>

注册PartialView:

<% using (Html.BeginForm("Register", "Member")) { %>
<fieldset>
    <legend>Register</legend>
    <p>
        <%= Html.LabelFor(x => x.Nickname) %>
        <%= Html.TextBoxFor(x => x.Nickname) %>
    </p>
    <p>
        <%= Html.LabelFor(x => x.Email) %>
        <%= Html.TextBoxFor(x => x.Email) %>
    </p>
    <p>
        <%= Html.LabelFor(x => x.Password) %>
        <%= Html.PasswordFor(x => x.Password) %>
    </p>
    <p>
        <%= Html.LabelFor(x => x.PasswordRepeat) %>
        <%= Html.PasswordFor(x => x.PasswordRepeat) %>
    </p>
    <input type="submit" value="Register" />
</fieldset>
<% } %>

我怎么能改变这个？

Answer 1

如果由于某种原因无法执行EditorTemplate,可以在View中执行此操作:

var dataDict = new ViewDataDictionary();
dataDict.TemplateInfo.HtmlFieldPrefix = "myPrefixHere";
Html.RenderPartial("myPartialViewName", myPartialViewModel, dataDict);

请注意,PartialView中的所有输入都将作为前缀.

感谢R0MANARMY指出这一点.

Answer 2

而不是使用Html.RenderPartial你可以使用将处理前缀的编辑器模板.

所以在你的主视图中:

<div>
    <%-- See below what does the second argument mean --%>
    <%= Html.EditorFor(x => x.RegisterModel, "RegisterModel") %>
</div>
<div>
    <%= Html.EditorFor(x => x.LoginModel, "LoginModel") %>
</div>

然后创建一个文件夹Views/Shared/EditorTemplates/RegisterModel.ascx(该文件的名称在EditorForhelper方法中使用).另请注意,此部分应强烈键入RegisterModel属性的类型:

<%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl<Ns.Models.RegisterModel>" %>

<% using (Html.BeginForm("Register", "Member")) { %>
<fieldset>
    <legend>Register</legend>
    <p>
        <%= Html.LabelFor(x => x.Nickname) %>
        <%= Html.TextBoxFor(x => x.Nickname) %>
    </p>
    <p>
        <%= Html.LabelFor(x => x.Email) %>
        <%= Html.TextBoxFor(x => x.Email) %>
    </p>
    <p>
        <%= Html.LabelFor(x => x.Password) %>
        <%= Html.PasswordFor(x => x.Password) %>
    </p>
    <p>
        <%= Html.LabelFor(x => x.PasswordRepeat) %>
        <%= Html.PasswordFor(x => x.PasswordRepeat) %>
    </p>
    <input type="submit" value="Register" />
</fieldset>
<% } %>

您可以为登录模型定义不同的部分 Views/Shared/EditorTemplates/LoginModel.ascx
