<p>My intent was to apply the JQuery UI Datepicker to my entire site by creating an EditorTemplate as per this post <a href="http://www.dalsoft.co.uk/blog/index.php/2010/04/26/mvc-2-templates/" rel="nofollow">ASP.NET MVC 2 Templates</a></p> <pre><code>@model DateTime @{ string name = ViewData.TemplateInfo.HtmlFieldPrefix; string id = name.Replace(".", "-"); <div class="editor-label"> @Html.LabelFor(model => model) </div> <div class="editor-field, datepicker"> @Html.EditorFor(model => model) @Html.ValidationMessageFor(model => model) </div> } </code></pre> <p>The associated code works perfectly as described; however, in addition to several DateTime fields, the Model also contains 1 nullable DateTime field and navigating to the page results in this error:</p> <p><em>The model item passed into the dictionary is null, but this dictionary requires a non-null model item of type 'System.DateTime'.</em></p> <p>In fact, even creating an empty partial named "DateTime" in the path Views/Shared/EditorTemplates is enough to generate the error, suggesting that even if the template were rewritten it may still not handle a null value. The code in the Index View (generated via MvcScaffolding via EF Code-First) is the same for both nullable and non-nullable DateTime fields:</p> <pre><code> <div class="editor-label"> @Html.LabelFor(model => model.ItemInstance.iArrivalDate) </div> <div class="editor-field,datepicker"> @Html.EditorFor(model => model.ItemInstance.iArrivalDate) @Html.ValidationMessageFor(model => model.ItemInstance.iArrivalDate) </div> </code></pre> <p>So is it possible to modify the template to handle the nullable DateTime?</p>

Guidance

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
