            <table class="pretty" id="dt">
                <thead>
                    <tr>
                        <th >
                            @Html.DisplayNameFor(model => model.Email)
                        </th>
                        <th>
                            @Html.DisplayNameFor(model => model.CurrentStorage)
                        </th>
                        <th>
                            @Html.DisplayNameFor(model => model.MaxStorage)
                        </th>
                        <th>
                            @Html.DisplayNameFor(model => model.LastLoginMonth)
                        </th>

                    </tr>
                </thead>
                <tbody>
                     @foreach (var item in Model.allUserManagers)
                    {
                        <tr>
                            <td>
                                @Html.DisplayFor(modelItem => item.Email)
                            </td>
                            <td>
                                @Html.DisplayFor(modelItem => item.CurrentStorage)
                            </td>
                            <td>
                                @Html.DisplayFor(modelItem => item.MaxStorage)
                            </td>
                            <td>
                                @Html.DisplayFor(modelItem => item.LastLoginMonth)
                            </td>

                        </tr>
                    }
                </tbody>
            </table>

i am totally confused how to solve this... where Email define in UserManager Class how i can access if i am doing something wrong

Your `FeedbackMixModel` does not have an `Email` property. Nor does it have `CurrentStorage`, `MaxStorage` or `LastLoginMonth`. Where are these properties located? — Arthur Rey, Jun 29 '16 at 17:31

Your actual FeedbackMixModel Model itself doesn't have a definition for the properties that you intend to use for your header :

<thead>
  <tr>
    <th>
      @Html.DisplayNameFor(model => model.Email)
    </th>
    <th>
      @Html.DisplayNameFor(model => model.CurrentStorage)
    </th>
    <th>
      @Html.DisplayNameFor(model => model.MaxStorage)
    </th>
    <th>
      @Html.DisplayNameFor(model => model.LastLoginMonth)
    </th>
  </tr>
</thead>

Your existing Model only contains two properties : allUserManagers and allFeedbacks, so it doesn't know what Email or some of the other properties you are referencing are. Based on your current code, these appear to be actual properties of your UserManager objects and not your actual FeedbackMixModel class.

You could consider hard-coding your header to express these properties :

<thead>
    <tr>
        <th>
          Email
        </th>
        <th>
          Current Storage
        </th>
        <th>
          Max Storage
        </th>
        <th>
          Last Login Month
        </th>
      </tr>
 </thead>

or you could attempt to target the first element in your collection similar to this approach:

<thead>
    <tr>
        <th>
          @Html.DisplayNameFor(x => Model.allUserManagers[0].Email)
        </th>
        <th>
          @Html.DisplayNameFor(x => Model.allUserManagers[0].CurrentStorage)
        </th>
        <th>
          @Html.DisplayNameFor(x => Model.allUserManagers[0].MaxStorage)
        </th>
        <th>
          @Html.DisplayNameFor(x => Model.allUserManagers[0].LastLoginMonth)
        </th>
      </tr>
 </thead>

this is the view model contain two others model UserManager and Feedback Email and other properties are defind in UserManager Class is there anyy method to access them??? — sajiii, Jun 29 '16 at 17:35
You could use an approach similar to the one provided that still uses the `DisplayNameFor()` helper to attempt to resolve the appropriate property names. — Rion Williams, Jun 29 '16 at 17:37
