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 = { , , , , , , , ,  };
             int[] capRowSpan = { , , , , , , , ,  };
             int[] capColSpan = { , , , , , , , ,  };
             GV1.Controls[].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[] { , , , , , , ,  };
             GV1.Controls[].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(, , DataControlRowType.Header, DataControlRowState.Normal);
         TableHeaderCell thc;
         for (int i = ; i < tcText.Length; i++)
         {
             thc = new TableHeaderCell();
             thc.Text = tcText[i];
             if (tcWidth[i] > ) { thc.Width = tcWidth[i]; }//若为0，则不设置width
             if (!noSpanRow)
             {
                 if (tcRowSpan[i] != ) { thc.RowSpan = tcRowSpan[i]; }
                 if (tcColSpan[i] != ) { thc.ColumnSpan = tcColSpan[i]; }
             }
             rowHeader.Cells.Add(thc);
         }
         return rowHeader;
     }
