<script src="~/Scripts/jqGrid/i18n/grid.locale-en.js" type="text/javascript"></script>
<script src="~/Scripts/jqGrid/plugins/grid.tbltogrid.js" type="text/javascript"></script>

<table id="table" class="table-bordered" cellpadding="5">
<tr><th>Name</th><th>Id</th></tr>
@foreach (var i in Model)
{
    <tr>
        <td>@i.Name</td>
