Answer 1

I am also new to MVC and I received the same error and found that it is not passing proper routeValues in the Index view or whatever view is present to view the all data.

It was as below

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

I changed it to the as show below and started to work properly.

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

Basically this error can also come because of improper navigation also.
