I've followed the instructions of Mac's answer <a href="https://stackoverflow.com/questions/2512809/has-anyone-implement-radiobuttonlistfort-for-asp-net-mvc">here</a> and I've built my own custom extension:

<pre><code>public static class HtmlHelperExtensions
{
 public static string HtmlIdNameFor&lt;TModel, TValue&gt;(
 this HtmlHelper&lt;TModel&gt; htmlHelper,
 System.Linq.Expressions.Expression&lt;Func&lt;TModel, TValue&gt;&gt; expression)
 {
 return (GetHtmlIdNameFor(expression));
 }

 private static string GetHtmlIdNameFor&lt;TModel, TValue&gt;(Expression&lt;Func&lt;TModel, TValue&gt;&gt; expression)
 {
 if (expression.Body.NodeType == ExpressionType.Call)
 {
 var methodCallExpression = (MethodCallExpression)expression.Body;
 string name = GetHtmlIdNameFor(methodCallExpression);
 return name.Substring(expression.Parameters[0].Name.Length + 1).Replace('.', '_');

 }
 return expression.Body.ToString().Substring(expression.Parameters[0].Name.Length + 1).Replace('.', '_');
 }

 private static string GetHtmlIdNameFor(MethodCallExpression expression)
 {
 var methodCallExpression = expression.Object as MethodCallExpression;
 if (methodCallExpression != null)
 {
 return GetHtmlIdNameFor(methodCallExpression);
 }
 return expression.Object.ToString();
 }
}
</code></pre>

I've imported my application's namespace

<pre><code>&lt;%@ Import Namespace="MvcApplication2" %&gt;
</code></pre>

and finally I can use my code like this:

<pre><code>&lt;%=Html.HtmlIdNameFor(m=&gt;m.Customer.Name)%&gt;
</code></pre>

See this question: <a href="https://stackoverflow.com/questions/5418898/get-the-generated-clientid-for-a-form-field">get the generated clientid for a form field</a>, this is my answer:

I use this helper:

<pre><code>public static partial class HtmlExtensions
{
 public static MvcHtmlString ClientIdFor&lt;TModel, TProperty&gt;(
 this HtmlHelper&lt;TModel&gt; htmlHelper, 
 Expression&lt;Func&lt;TModel, TProperty&gt;&gt; expression)
 {
 return MvcHtmlString.Create(
 htmlHelper.ViewContext.ViewData.TemplateInfo.GetFullHtmlFieldId(
 ExpressionHelper.GetExpressionText(expression)));
 }
}
</code></pre>

Use it just as you would any other helper: <code>@Html.ClientIdFor(model=&gt;model.client.email)</code>

blocks|key|1022349|text|ASP.NET+MVC4内置了Html.IdFor()，可以返回以下内容：|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|1022350|@Html.IdFor(m+=>+m.User.Surname)|code-block|syntax|javascript|1022351|entityMap|0|LINK|mutability|MUTABLE|url|http://msdn.microsoft.com/en-us/library/hh833709%2528v=vs.108%2529.aspx^0|F|C|0|0|0^^$0|@$1|2|3|4|5|6|7|Q|8|@]|9|@$A|R|B|S|1|T]]|C|$]]|$1|D|3|E|5|F|7|U|8|@]|9|@]|C|$G|H]]|$1|I|3|-4|5|6|7|V|8|@]|9|@]|C|$]]]|J|$K|$5|L|M|N|C|$O|P]]]]

ASP.NET MVC 4 has <a href="http://msdn.microsoft.com/en-us/library/hh833709%28v=vs.108%29.aspx">Html.IdFor()</a> built in that can return this:

<pre><code>@Html.IdFor(m =&gt; m.User.Surname)
</code></pre>

I use the HTML Helpers to render my fields:

<pre><code>&lt;%=Html.EditorFor(m =&gt; m.User.Surname)%&gt;
</code></pre>

and the output would be something like this:

<pre><code>&lt;input class="text-box single-line" id="User_Surname" 
 name="User.Surname" type="text" value="" /&gt;
</code></pre>

The helper uses the className + '.' è fieldName to build the id. 
I need to pass the id to a jQuery function. Is there a way to have it without hardcoding it?
Maybe an helper which can use the ASP.NET MVC2 conventions?

How to get the HTML id generated by asp.net MVC EditorFor

jQuery

我使用HTML Helpers来呈现我的字段：<%=Html.EditorFor(m => m.User.Surname)%>输出结果如下所示：<input class="text-box single-line" id="User_Surname" name="User.Surname" type...
