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。

Code

1          #region Insert GridView Row

3          private void InsertSubTotalRow( int subTotalRow, int amountNumber, decimal totalAmount, int remindTextIndex, string remindText)

7              // Set the background color of row

16
17                  // According to the first column of GridView to set the display of the cell and cross out the number
