    text
    copied!<p>Suppose I have ViewModel like</p> <pre><code>public class AnotherViewModel { public string Name { get; set; } } public class MyViewModel { public string Name { get; set; } public AnotherViewModel Child { get; set; } public AnotherViewModel Child2 { get; set; } } </code></pre> <p>In the view I can render a partial with </p> <pre><code>&lt;% Html.RenderPartial("AnotherViewModelControl", Model.Child) %&gt; </code></pre> <p>In the partial I'll do</p> <pre><code>&lt;%= Html.TextBox("Name", Model.Name) %&gt; or &lt;%= Html.TextBoxFor(x =&gt; x.Name) %&gt; </code></pre> <p>However, the problem is that both will render name="Name" while I need to have name="Child.Name" in order for model binder to work properly. Or, name="Child2.Name" when I render the second property using the same partial view.</p> <p>How do I make my partial view automatically recognize the required prefix? I can pass it as a parameter but this is too inconvenient. This is even worse when I want for example to render it recursively. Is there a way to render partial views with a prefix, or, even better, with automatic reconition of the calling lambda expression so that </p> <pre><code>&lt;% Html.RenderPartial("AnotherViewModelControl", Model.Child) %&gt; </code></pre> <p>will automatically add correct "Child." prefix to the generated name/id strings?</p> <p>I can accept any solution, including 3-rd party view engines and libraries - I actually use Spark View Engine (I "solve" the problem using its macros) and MvcContrib, but did not find a solution there. XForms, InputBuilder, MVC v2 - any tool/insight that provide this functionality will be great.</p> <p>Currently I think about coding this myself but it seems like a waste of time, I can't believe this trivial stuff is not implemented already.</p> <p>A lot of manual solutions may exists, and all of them are welcome. For example, I can force my partials to be based off IPartialViewModel&lt;T&gt; { public string Prefix; T Model; }. But I'd rather prefer some existing/approved solution.</p> <p>UPDATE: there's a similar question with no answer <a href="https://stackoverflow.com/questions/955371/partial-view-with-parametrized-prefix-for-controls-names">here</a>.</p>
