推荐答案

试试这个

Try this

if (e.Row.RowType == DataControlRowType.Header)
        {
            GridView HeaderGrid = (GridView)sender;
            GridViewRow HeaderGridRow =
            new GridViewRow(0, 0, DataControlRowType.Header,
            DataControlRowState.Insert);

            TableCell HeaderCell = new TableCell();
            HeaderCell.Text = "";
            HeaderCell.ColumnSpan = 5;
            HeaderCell.HorizontalAlign = HorizontalAlign.Center;
            HeaderGridRow.Cells.Add(HeaderCell);

            HeaderCell = new TableCell();
            HeaderCell.Text = "Mortality";
            HeaderCell.ColumnSpan = 4;
            HeaderCell.HorizontalAlign = HorizontalAlign.Center;
            HeaderGridRow.Cells.Add(HeaderCell);

            HeaderCell = new TableCell();
            HeaderCell.Text = "";
            HeaderCell.ColumnSpan = 1;
            HeaderCell.HorizontalAlign = HorizontalAlign.Center;
            HeaderGridRow.Cells.Add(HeaderCell);

            HeaderCell = new TableCell();
            HeaderCell.Text = "CUM Feed Intake";
            HeaderCell.ColumnSpan = 2;
            HeaderCell.HorizontalAlign = HorizontalAlign.Center;
            HeaderGridRow.Cells.Add(HeaderCell);

            HeaderCell = new TableCell();
            HeaderCell.Text = "Body Weight";
            HeaderCell.ColumnSpan = 3;
            HeaderCell.HorizontalAlign = HorizontalAlign.Center;
            HeaderGridRow.Cells.Add(HeaderCell);

            HeaderCell = new TableCell();
            HeaderCell.Text = "F.C.R";
            HeaderCell.ColumnSpan = 2;
            HeaderCell.HorizontalAlign = HorizontalAlign.Center;
            HeaderGridRow.Cells.Add(HeaderCell);

            HeaderCell = new TableCell();
            HeaderCell.Text = "Feed Details";
            HeaderCell.ColumnSpan = 4;
            HeaderCell.HorizontalAlign = HorizontalAlign.Center;
            HeaderGridRow.Cells.Add(HeaderCell);

            HeaderCell = new TableCell();
            HeaderCell.Text = "Feed Requirement";
            HeaderCell.ColumnSpan = 3;
            HeaderCell.HorizontalAlign = HorizontalAlign.Center;
            HeaderGridRow.Cells.Add(HeaderCell);

            HeaderCell = new TableCell();
            HeaderCell.Text = "";
            HeaderCell.ColumnSpan = 2;
            HeaderCell.HorizontalAlign = HorizontalAlign.Center;
            HeaderGridRow.Cells.Add(HeaderCell);

            GVIntReport.Controls[0].Controls.AddAt(0, HeaderGridRow);

        }

您可以对DataGrid使用类似的代码:

You can use similar code for DataGrid:

protected void Grid1_ItemCreated(object sender, DataGridItemEventArgs e)
{
    if (e.Item.ItemType == ListItemType.Header)
    {
        DataGrid grid = sender as DataGrid;
        DataGridItem dgi = new DataGridItem(0, e.Item.DataSetIndex, ListItemType.Header);
        dgi.Cells.Add(new TableCell { ColumnSpan = 2, Text = "Name" });
        dgi.Cells.Add(new TableCell { ColumnSpan = 2, Text = "Date" });
        Table t = grid.Controls[0] as Table;
        t.Rows.AddAt(0, dgi);
    }
}
