添加第二個標題行到GridView下面已經存在的標題行

Question

我想動態地在GridView的OnRowCreated事件中插入第二個標題行。但是，我似乎無法將行插入到gridview的行索引中的第一個位置之外的任何地方。下面的代碼在最後一行失敗，其中標題實際上被添加到網格中。索引超出界限例外。我如何在下面添加這個標題行已經存在的標題行？非常感謝幫助，謝謝！

protected void gvwProd_RowCreated(object sender, GridViewRowEventArgs e) 
{ 
    if (e.Row.RowType == DataControlRowType.Header) 
    { 
     GridView gvw = (GridView)sender; 

     GridViewRow HeaderRow = new GridViewRow(1, 1, DataControlRowType.Header, DataControlRowState.Insert); 

     TableCell HeaderCell = new TableCell(); 
     HeaderCell.Text = "Prod Comments - TS/LID"; 
     HeaderCell.Style["font-weight"] = "bold"; 
     HeaderCell.ColumnSpan = 4; 
     HeaderCell.Wrap = false; 
     HeaderRow.Cells.Add(HeaderCell); 

     HeaderCell = new TableCell(); 
     HeaderCell.Text = "Materials Comments - TS/LD"; 
     HeaderCell.Style["font-weight"] = "bold"; 
     HeaderCell.ColumnSpan = 8; 
     HeaderCell.Wrap = false; 
     HeaderRow.Cells.Add(HeaderCell); 

     HeaderCell = new TableCell(); 
     HeaderCell.Text = "Plant Comments - TS/LID"; 
     HeaderCell.Style["font-weight"] = "bold"; 
     HeaderCell.ColumnSpan = 11; 
     HeaderCell.Wrap = false; 
     HeaderRow.Cells.Add(HeaderCell); 

     gvw.Controls[0].Controls.AddAt(1, HeaderRow); 
    } 
}

也有類似的問題。你可以嘗試鑄造的GridView的表並訪問.Rows方法：

((Table)gvw.Controls[0]).Rows.AddAt(1, HeaderRow);
