GridView多行标题行、改造标题行、自定义标题行完美版

网上找了个找，最终还是自己做的比较靠谱，道理很简单，直接看代码

代码：

 

    /// <summary>
    /// ===================  两行标题行  ========================
    /// </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", "材料名称", "规格型号", "计量单位", "入库数量", "点验", "发料", "库存", "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[] { "数量", "金额", "数量", "金额", "数量", "金额", "单价", "金额" };
            capWidth = new int[] { 70, 80, 70, 80, 70, 80, 70, 80 };
            GV1.Controls[0].Controls.Add(CreateHeaderRow(capText, capWidth, capRowSpan, capColSpan, true));
        }
    }
    /// <summary>
    /// =====================  自定义标题行的方法  =========================
    /// </summary>
    /// <param name="tcText">单元格Text</param>
    /// <param name="tcWidth">单元格宽度，为0则不设置宽度</param>
    /// <param name="tcRowSpan">RowSpan</param>
    /// <param name="tcColSpan">ColumnSpan</param>
    /// <param name="noSpanRow">若为True，则忽略行、列的合并Span</param>
    /// <returns>一行标题行</returns>
    private GridViewRow CreateHeaderRow(string[] tcText, int[] tcWidth, int[] tcRowSpan, int[] tcColSpan, bool noSpanRow = false)
    {
        GridViewRow rowHeader = new GridViewRow(0, 0, DataControlRowType.Header, DataControlRowState.Normal);
        TableHeaderCell thc;
        for (int i = 0; i < tcText.Length; i++)
        {
            thc = new TableHeaderCell();
            thc.Text = tcText[i];
            if (tcWidth[i] > 0) { thc.Width = tcWidth[i]; }//若为0，则不设置width
            if (!noSpanRow)
            {
                if (tcRowSpan[i] != 1) { thc.RowSpan = tcRowSpan[i]; }
                if (tcColSpan[i] != 1) { thc.ColumnSpan = tcColSpan[i]; }
            }
            rowHeader.Cells.Add(thc);
        }
        return rowHeader;
    }
