GridView多行標題行、改造標題行、自定義標題行完美版

網上找了個找，最終還是自己做的比較靠譜，道理很簡單，直接看代碼

 

代碼：

 

    /// <summary>
    /// ===================  兩行標題行  ========================
    /// </summary>
    /// <param name="sender"></param>
    /// <param name="e"></param>
    protected void GV1_RowCreated(object sender, GridViewRowEventArgs e)
    {
        if (e.Row.RowType == DataControlRowType.Header)
        {
            e.Row.Cells.Clear();
            string[] capText = { "ID", "材料名稱", "規格型號", "計量單位", "入庫數量", "點驗", "發料", "庫存", "合同" };
            int[] capWidth = { 50, 0, 0, 0, 70, 150, 150, 150, 150 };
            int[] capRowSpan = { 2, 2, 2, 2, 2, 1, 1, 1, 1 };
            int[] capColSpan = { 1, 1, 1, 1, 1, 2, 2, 2, 2 };
            GV1.Controls[0].Controls.Add(CreateHeaderRow(capText, capWidth, capRowSpan, capColSpan));

            capText = new string[] { "數量", "金額", "數量", "金額", "數量", "金額", "單價", "金額" };
            capWidth = new int[] { 70, 80, 70, 80, 70, 80, 70, 80 };
            GV1.Controls[0].Controls.Add(CreateHeaderRow(capText, capWidth, capRowSpan, capColSpan, true));
        }
    }
    /// <summary>

    /// </summary>

            if (!noSpanRow)
