After I add _TablePartialButton to Index.cshtml I get error, but when I restore to default HTML.ActionResult() method it works fine Any suggestion, comment?

Answer 1

Check the spelling of your controller name and view name. 404 is the resource not found error.

Answer 2

in your index.cshtml file you need to add the primary key to the ACTIONLINK

This is generated

 <td>
    @Html.ActionLink("Edit", "Edit", new { /* id=item.PrimaryKey */ }) |
    @Html.ActionLink("Details", "Details", new { /* id=item.PrimaryKey */ }) |
    @Html.ActionLink("Delete", "Delete", new { /* id=item.PrimaryKey */ })
    </td>

key is commented out
