gridview如何手动增加一行？

Question

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
GridViewRow rowSeparator = new GridViewRow(0, 0, DataControlRowType.DataRow, DataControlRowState.Normal);
                                      TableCell separatorCell = new TableCell();
                    separatorCell.ColumnSpan = 1;
                    rowSeparator.Cells.Add(separatorCell);
                    
                    rowSeparator.Visible = true;
                    //在GridView中的相应行插入行
                    GridView1.Controls[0].Controls.AddAt(this.GridView1.Rows.Count, rowSeparator);
}我这么写，但是运行后并没有添加一行，应该怎么写呢？

Answer 1

给GridView加行   选择更改数据源是最合适的。

应该这么写protected void GrvCode_RowCreated(object sender, GridViewRowEventArgs e)
     {
         int num = 0;
         num = GrvCode.Rows.Count;
         if (e.Row.RowType == DataControlRowType.Footer)
         {
             int left = GrvCode.PageSize - num;
             int numCol = GrvCode.Rows[0].Cells.Count;             for(int i=0;i<left;i++)
             {
                 GridViewRow row = new GridViewRow(-1,-1,DataControlRowType.EmptyDataRow,DataControlRowState.Normal);
                 for (int j = 0; j < numCol; j++)
                 {
                     TableCell cell = new TableCell();
                     cell.Text = "&nbsp";
                     row.Cells.Add(cell);
                 }
                 GrvCode.Controls[0].Controls.AddAt(num+1+i,row);
             }
         }
     }
