GridView 动态 添加新行

这是GridView动态添加行的基本代码，可以进行修改扩充，实现自己想要的动态添加行效果。

Code
 1             //创建一个GridView的一个分隔行(根据DataControlRowType来设置)
 2             GridViewRow rowSeparator = new GridViewRow(0, 0, DataControlRowType.Separator, DataControlRowState.Normal);
 3             //设置行的底色
 4             rowSeparator.BackColor = System.Drawing.Color.White;
 5             //设置单元格集
 6             //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
 7             TableCellCollection cells = e.Row.Cells;
 8             //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
 9             TableCell separatorCell = new TableCell();
10             //根据GridView的第一列的显示情况设置单元格和跨列数
11             if (gvMain.Columns[0].Visible == true)
12             {
13                 separatorCell.ColumnSpan = cells.Count;
14             }
15             else
16             {
17                 separatorCell.ColumnSpan = cells.Count - 1;
18             }
19             //单元格的对齐
20             separatorCell.HorizontalAlign = HorizontalAlign.Right;
21             //单元格的背景色
22             separatorCell.BackColor = System.Drawing.Color.FromArgb(226, 226, 226);
23             //单元格的高度
24             separatorCell.ControlStyle.Height = 5;
25             //在单元格集中增加单元格控件
26             rowSeparator.Cells.Add(separatorCell);
27             //设置GridView行的可见性
28             rowSeparator.Visible = true;
29             //在GridView中的相应行插入行
30             gvMain.Controls[0].Controls.AddAt(e.Row.RowIndex + 1, rowSeparator);

 

这是在项目中的一个实例，是动态添加按照某一个属性来统计总数SubTotal的例子，可以参照下，有不明白的地方可以给我留言或者发表评论。
