我已经要求
question知道为什么在我的应用程序中,当我使用模型绑定来验证模型(TryUpdateModel())时,文本框被突出显示(即红色边框和粉红色阴影背景应用于文本框)但是当我使用时手动验证(ModelState.AddModelError).现在已经2天了,没有任何答案.我自己尝试过所有事情而没有成功.所以,我决定以不同的方式提出这个问题.
我理解IT的方式,这就是ModelBinding如何处理请求.
> ModelBinding从httpcontext获取传入值
>它实例化该模型的对象
>尝试将这些值解析为对象
>如果某个属性出现问题,它会使用ModelState.AddModelError标记出现错误的属性.
>重新显示视图
这是我的问题当重新显示表单时：
正在为其值无效突出显示的文本框做了什么？
我知道Site.css中的类很少,例如.input-validation-error和.field-validation-error应用于文本框.也许ModelBinding在内部使用一个命令,如AddCss(“#MyTextBox”,“.input-validation-error”).
如果我知道它是如何工作的,我可以(也许)手动解决我的问题.

根据@Ian Galloway的要求,这是代码

我选择了一个视图(因为他们都遇到了同样的问题).该视图称为StateObjectifs.aspx
<asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server">
<!-- Script Begin -->
<script src="../../Scripts/tiny_mce/tiny_mce.js" type="text/javascript"></script>
<script type = "text/javascript">
tinyMCE.init({
mode: "textareas",theme: "advanced",theme_advanced_toolbar_location: "top",theme_advanced_toolbar_align: "left",theme_advanced_statusbar_location: "bottom",theme_advanced_resizing: true
});
</script>
<!-- End Script -->
<fieldset id = "StateObjectifs">
<legend>Etape 5:</legend>
<div id = "left-pane" style = "width:700px">
<%using (Html.BeginForm("StateObjectifs","Registration"))
{ %>
<%: Html.ValidationSummary() %>
<% = Html.Serialize("formviewmodel",Model) %>
<table>
<tr>
<th><% = Html.LabelFor(x=>x.registrationData.Objective) %></th>
<td><% = Html.TextBoxFor(x=>x.registrationData.Objective) %>
<%: Html.ValidationMessageFor(x =>x.registrationData.Objective,"*")%></td>
</tr>
<tr>
<th colspan = "2"><% = Html.LabelFor(x =>x.registrationData.RequestDetails) %></th>
</tr>
<tr>
<td colspan = "2">
<% = Html.TextAreaFor(x =>x.registrationData.RequestDetails,10,75,null) %>
</td>
</tr>
</table>
</div>
<div id = "right-pane">
<ul>
<li>Les cases pour lesquelles le titre se termine par (*) sont obligatoires</li>
<li>Pour mieux vous servir,veuillez décrire clairement de manière concise
votre requête. Par exemple: <i>Les données de l'USAID sur le secteur santé pour l'année 2009</i></li>
</ul>
</div>
<div class = "clear"></div>
<fieldset>
<% Html.RenderPartial("NavigationView",Model.navigationData); %>
</fieldset>
</fieldset>
<%} %>
谢谢你的帮助.
