如何在DataGridView中添加新的空行？

我有一個DataGridView，我想添加一個新的行與空單元格，但我不知道在DataGridView中的列（變量）的數量。有沒有簡單的方法來做到這一點？如何在DataGridView中添加新的空行？

您可以使用以下代碼輕鬆完成此操作。下面的標記用於帶有gridview的頁面，下面的C＃代碼用於按鈕單擊事件，該事件添加了一個沒有任何特定的列名稱或數據類型知識的空行。

這是嘗試和測試。

爲按鈕C＃代碼點擊添加一個新的空行

protected void btn1_Click(object sender, EventArgs e) 
{ 
    GridViewRow row1 = GridView1.Rows[0]; 
    GridViewRow row = new GridViewRow(0, 0, DataControlRowType.DataRow, DataControlRowState.Insert); 
    for (int i = 0; i < row1.Cells.Count; i++) 
    { 
     TableCell cell = new TableCell(); 
     cell.Text = "&nbsp;"; 
     row.Cells.Add(cell); 
     Table parentTable = row1.Parent as Table; 
     parentTable.Rows.Add(row); 
    } 
}

ASPX標記與GridView控件
