  • 分享两段行列合并算法

    使用一个将指定行列的gridview横向纵向合并行列,实现多复杂表头样式

    调用:

    GridCommon.Unitelist(this.grid1, 4);

    GridCommon.GroupCol(this.grid1, 4, dt.Columns.Count);

            /// <summary>
            /// 横向合并列
            /// </summary>
            public static void Unitelist(GridView gv, int rowIndex)
            {
                if (gv.Rows.Count < 1)
                {
                    return;
                }
                TableRow tr;
                for (int i = 0; i < rowIndex; i++)
                {
                    tr = gv.Rows[i];
                    if (gv.Rows[i].Cells.Count < 1)
                    {
                        return;
                    }
                    TableCell otcell = gv.Rows[i].Cells[0];
                    otcell.BackColor = System.Drawing.Color.FromArgb(219, 234, 253); //System.Drawing.Color.Teal;
                    otcell.HorizontalAlign = HorizontalAlign.Center;
                    for (int j = 1; j < gv.Rows[i].Cells.Count; j++)
                    {
                        TableCell tcell = gv.Rows[i].Cells[j];
                        if (tcell.Text == otcell.Text)

                            {
                                otcell.ColumnSpan = 1;
                            }
                            otcell.ColumnSpan++;
                            otcell.VerticalAlign = VerticalAlign.Middle;
