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

<%
    using (MvcApplication1.Models.EgovtDataContext _model = new MvcApplication1.Models.EgovtDataContext())
    {
%>

    <% foreach(var md in MvcApplication1.Models.) { %>

           { %>

        <% } %>
    <% } %>

FeatureRepository Class

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;

namespace MvcApplication1.Models
{
    public class FeaturesRepository
    {
        EgovtDataContext db = new EgovtDataContext();

        public IEnumerable<Feature> GetAllFeatures()
        {
            List<Feature> Features = new List<Feature>();
            Feature feature = new Feature();


            var AllParentFeatures = FeaturesByParentId(0);
            foreach (Feature frParentCategory in AllParentFeatures)
            {
                feature.int_FeatureId = frParentCategory.int_FeatureId;

                feature.vcr_FeaturesName = frParentCategory.vcr_FeaturesName;
                feature.int_ParentId = frParentCategory.int_ParentId;
                Features.Add(feature);


                var AllChildFeaturesofthatParent = FeaturesByParentId(frParentCategory.int_FeatureId);
                int AllChildFeaturesofthatParentCount = AllChildFeaturesofthatParent.Count();
                foreach (Feature frChildCategory in AllChildFeaturesofthatParent)
                {
                    feature.int_FeatureId = frParentCategory.int_FeatureId;

                    feature.vcr_FeaturesName = frParentCategory.vcr_FeaturesName;
                    feature.int_ParentId = frParentCategory.int_ParentId;
                    Features.Add(feature);
                }

            }
            return Features;

        }

    }
}

1) is this rightly done public IEnumerable GetAllFeatures() in the method above?And the method correctly written?
2) I want to call the GetAllFeatures method in the control above ? how would i do that?
3) User Controller should be created in shared folder? What is shared folder for?

Answer 1

Create a controller action

public ActionResult All()
{
    return View(new FeaturesRepository().GetAllFeatures());
}

And change your usercontrol declaration

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


<% foreach(var md in Model) 
   { %>
        <% if (md.ParentId == 0)
           { %>
               //blabla
        <% } %>
<% } %>
