How to put an additional summary row on the top of the grid rows with ASPxGridView (Devexpress)?

The default behavour

When I configure total summaries, with the <TotalSummary> node of my ASPxGridView, those totals are display at the bottom of the grid.

My goal

My question is how to make them appear both on the top and the bottom of the开发者_StackOverflow grid ? The position of the top total row would be between the header (column captions / filter) and the first data row.

I'm using the 2011v1 release of ASPxGridView and editors product.

If I understand your question clearly,

For the bottom, you can do it normally with totalsummary,

For the top, you can do it like this;

protected void ASPxLabel1_Load(object sender, EventArgs e)
        {
            ASPxGridView grid = ASPxGridView1;
            GridViewDataColumn col = grid.Columns["UnitsInStock"] as GridViewDataColumn;
            ASPxSummaryItem summary = grid.TotalSummary["UnitsInStock",
DevExpress.Data.SummaryItemType.Sum];
            string text = summary.GetTotalFooterDisplayText(col, grid.GetTotalSummaryValue(summary));
            ASPxLabel label = (ASPxLabel)sender;
            label.Text = string.Format("{0}\r\n({1})", col.FieldName, text);

        }

It gives you a result like this;
