gridview 中对表头进行修改（多层）

后台事件函数

 

protected void gvRadar_RowCreated(object sender, GridViewRowEventArgs e)
        {
            if (e.Row.RowType == DataControlRowType.Header)
            {
                TableCellCollection tcl = e.Row.Cells;
                //清除自动生成的表头
                tcl.Clear();


                //添加新的表头
                tcl.Add(new TableHeaderCell());
                tcl[0].RowSpan = 2;                                //合并行
                tcl[0].Text = "台站号";
                Label l1 = new Label();
                l1.Text = "台站号";
                //因为自定义表头,所以原来系统中实现的排序功能就失效了
                //下面语句可以自己在表头中添加控件,自己实现排序功能
                tcl[0].Controls.Add(l1);


                tcl.Add(new TableHeaderCell());
                tcl[1].RowSpan = 2;                             //合并列
                tcl[1].Text = "台站名";

                tcl.Add(new TableHeaderCell());
                tcl[2].RowSpan = 2;                                //合并行
                tcl[2].Text = "应发报台次";

                tcl.Add(new TableHeaderCell());
                tcl[3].ColumnSpan = 2;                             //合并列
                tcl[3].Text = "及时报";

                tcl.Add(new TableHeaderCell());
                tcl[4].ColumnSpan = 2;
                tcl[4].Text = "逾限报";



                tcl.Add(new TableHeaderCell());
                tcl[5].ColumnSpan = 2;

                //这段是重点 其实在生成的html中tcl[5]转化为<th>标题5</th>
                //所以依照该原则注入html标签来实现,原理有些类似于SQL注入攻击
                //tcl[5].Text = "标题5</th></tr><tr><th>标题2-1</th><th> 标题2-2</th><th>标题4-1</th><th>标题4-2< /th><th>标题4-3<th>标题6</th><th>标题7< /th><th>标题8<th>标题9</th>";

                tcl[5].Text = "缺报</th></tr><tr><th>站次</th><th>百分率</th><th>站次</th><th>百分率</th><th>站次</th><th>百分率";


            }
