Conditionally hiding columns

[Sam Stange]

I'm trying to hide a column conditionally, but having some trouble. I can get the column to "hide", but the header and footer row still shows up and the data is moved over one column. I've tried it various ways, but that header row/footer still shows up. Is this a bug?

Here's the code I'm using to conditionally hide the delete action.

@(Html.Telerik().Grid(Model)
    .Name("Grid")

    .Sortable()
    .Pageable(pager => pager.PageSize(15))
        .Columns(columns =>
        {
            columns.Template(@<text><a href="PreviewEmail/@item.EmailID" class="Preview">View Email</a></text>).Width(50).Title("View Email");
            columns.Template(o => Html.ActionLink("Delete", "DeleteEmail", new { id = o.EmailID })).Width(50).Title("Delete");
            columns.Bound(o => o.ParentOrgName).Width(300).Title("Parent Org");
            columns.Bound(o => o.ToAddress).Width(250).Title("To://");
            columns.Bound(o => o.JobRequestID).Hidden(true);
            columns.Bound(o => o.WorkItemID).Hidden(true);
            columns.Bound(o => o.EmailID).Hidden(true);
            })
        .CellAction(cell =>
        {
            if (cell.Column.Title == "Delete")
            {
                if (cell.DataItem.JobStatus.JobRequestStatusName == "Emails Sent") //check whether to hide the cell
                {
                    cell.Column.Hidden = true;
                    cell.Column.HeaderHtmlAttributes["style"] = "visibility:hidden";
                    cell.HtmlAttributes["style"] = "visibility:hidden";
                    cell.Column.HtmlAttributes["style"] = "visibility:hidden";
               }
            }
        }
        )
    )
