Gridview创建行列合并列、行类

Gridview创建行列

1种.

//行
GridViewRow rowHeader = new GridViewRow(0, 0, DataControlRowType.Header, DataControlRowState.Normal);

//TH
TableCell th = new TableHeaderCell();

//TD
TableCell td = new TableCell();

//添加单元格
rowHeader.Cells.Add(headerCell);
rowHeader.Visible = true;

//添加行
GridView1.Controls[0].Controls.AddAt(0, rowHeader);

2.种

            //创建一个GridView的一个分隔行(根据DataControlRowType来设置)
            GridViewRow rowSeparator = new GridViewRow(0, 0, DataControlRowType.Separator, DataControlRowState.Normal);
            //设置行的底色
            rowSeparator.BackColor = System.Drawing.Color.White;
            //设置单元格集
            //可以根据实际情况设置，我在这儿是根据RowDataBound事件（e参数）来设置的
            TableCellCollection cells = e.Row.Cells;
            //设置单元格，根据实际情况增加，我这儿是增加一个跨所有列的行
            TableCell separatorCell = new TableCell();
            //根据GridView的第一列的显示情况设置单元格和跨列数
            if (gvMain.Columns[0].Visible == true)
            {
               separatorCell.ColumnSpan = cells.Count;
            }
            else
            {
                separatorCell.ColumnSpan = cells.Count - 1;
            }
             //单元格的对齐
            separatorCell.HorizontalAlign = HorizontalAlign.Right;
            //单元格的背景色
            separatorCell.BackColor = System.Drawing.Color.FromArgb(226, 226, 226);
            //单元格的高度
            separatorCell.ControlStyle.Height = 5;
             //在单元格集中增加单元格控件
            rowSeparator.Cells.Add(separatorCell);
            //设置GridView行的可见性
            rowSeparator.Visible = true;
            //在GridView中的相应行插入行
            gvMain.Controls[0].Controls.AddAt(e.Row.RowIndex + 1, rowSeparator);
