Question

I am creating a UserControl that will read data from an XML file and populate a ListBox. I’ve open up the .ascx file and would like to use @foreach (etc..) but this isn’t valid?

Can someone explain why this isn’t possible? Or maybe confirm if UserControls are deprecated in MVC 3?

.ascx is WebForms. @ is Razor, meaning that if you want to write @foreach(...) you need a Razor template: Foo.cshtml:

@model IEnumerable<AppName.Models.Foo>
@foreach (var item in Model)
{
    ...
}

And if you want WebForms user control Foo.ascx:

<%@ Control 
    Language="C#" 
    Inherits="System.Web.Mvc.ViewUserControl<IEnumerable<AppName.Models.Foo>>" 
%>
<% foreach(var item in Model) { %>
    ...
<% } %>
