The use of the following template prevents client validatation from running:

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

<% if (ViewData.TemplateInfo.TemplateDepth > 1) { %>

<%= ViewData.ModelMetadata.SimpleDisplayText %>

<% } else { %>

<table cellpadding="5" cellspacing="5" border="0">

<% foreach (var prop in ViewData.ModelMetadata.Properties.Where(pm => pm.ShowForEdit && !ViewData.TemplateInfo.Visited(pm))) { %>

<% if (prop.HideSurroundingHtml) { %>

<%= Html.Editor(prop.PropertyName) %>

<% } else {%> <% Html.RenderPartial("~/Areas/Editor/Views/Shared/EditorTemplates/EditorRow.ascx", prop); %> <% }%>

<% } %>

</table>

<% } %>

The partial view:

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

<tr>

<td>

<div class="editor-label" style="text-align: right;">

<%= Model.IsRequired ? "*" : ""%>

<%= Html.Label(Model.PropertyName)%>

</div>

</td>

<td>

<div class="editor-field">

<%= Html.Editor(Model.PropertyName)%>

<%= Html.ValidationMessage(Model.PropertyName, "*")%>

</div>

</td>

</tr>

It all works fine, if you don't use a partial view like here:

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

<% if (ViewData.TemplateInfo.TemplateDepth > 1) { %>

<%= ViewData.ModelMetadata.SimpleDisplayText %>

<% } else { %>

<table cellpadding="0" cellspacing="0" border="0">

<% foreach (var prop in ViewData.ModelMetadata.Properties.Where(pm => pm.ShowForEdit && !ViewData.TemplateInfo.Visited(pm))) { %>

<% if (prop.HideSurroundingHtml) { %>

<%= Html.Editor(prop.PropertyName) %>

<% } else { %>

<tr>

<td>

<div class="editor-label" style="text-align: right;">

<%= prop.IsRequired ? "*" : "" %>

<%= Html.Label(prop.PropertyName) %>

</div>

</td>

<td>

<div class="editor-field">

<%= Html.Editor(prop.PropertyName) %>

<%= Html.ValidationMessage(prop.PropertyName, "*") %>

</div>

</td>

</tr>

<% } %>

</table>

<% } %>

This is not critical, but would make live much easier for me.
Besides from that, great components!

Kind Regards,
Michael

Hello Michael Sander,

I believe that the aforementioned behavior is expected. MVC client validation relies on some additional javascript values, which are not rendered in this case. Here you can check some threads devoted on the same matter:
