I'm trying to write an auto-scaffolder for Index views. I'd like to be able to pass in a collection of models or view-models (e.g., IQueryable<MyViewModel>
) and get back an HTML table that uses the DisplayName
attribute for the headings (th
elements) and Html.Display(propertyName)
for the cells (td
elements). Each row should correspond to one item in the collection.
Here's what I have so far:
<%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl" %>
<%
var items = (IQueryable<TestProj.ViewModels.TestViewModel>)Model;
// Should be generic!
var properties = items.First().GetMetadata().Properties
.Where(pm => pm.ShowForDisplay && !ViewData.TemplateInfo.Visited(pm));
%>
<table>
<tr>
<%
foreach(var property in properties)
{
%>
<th>
<%= property.DisplayName %>
</th>
<%
}
%>
</tr>
<%
foreach(var item in items)
{
%>
<tr>
<%
foreach(var property in properties)
{
%>
<td>
<%= Html.Display(property.DisplayName) %>
// This doesn't work!
</td>
<%
}
%>
</tr>
<%
}
%>
</table>
Two problems with this:
I'd like it to be generic. So, I'd like to replace
var items = (IQueryable<TestProj.ViewModels.TestViewModel>)Model;
withvar items = (IQueryable<T>)Model;
or something to that effect.The
<td>
elements are not working because theHtml
in<%= Html.Display(property.DisplayName) %>
contains the model for the view, which is a collection of items, not the item itself. Somehow, I need to obtain anHtmlHelper
object whoseModel
property is the currentitem
, but I'm not sure how to do that.
How do I solve these two problems?
