could be something like this:

@{
var grid = new WebGrid(canPage: true, rowsPerPage: ThisController.PageSize, canSort: true,    ajaxUpdateContainerId: "grid");
grid.Bind(Model.Employees, rowCount: Model.TotalRecords, autoSortAndPage: false);
grid.Pager(WebGridPagerModes.All);
@grid.GetHtml(htmlAttributes: new { id="grid" },
    columns: grid.Columns(
        grid.Column(format: (item) => Html.ActionLink("Edit", "Edit", new { EmployeeID = item.EmployeeID, ContactID = item.ContactID })),
        grid.Column("FullName"),
        grid.Column("Title")
    ));
}
