使用GridView自定义表头功能实现与数据绑定

 


gridview  加控件表头（在后台并保留原先的表头）在GridView1_RowCreated的事件中写



1.

if (e.Row.RowType == DataControlRowType.Header)//如果创建的是表头
            {
                //GridViewRow rowHeader = new GridViewRow(0, 0, DataControlRowType.Header, DataControlRowState.Normal);//表头行

                //int i = 0;
                ////数据库中的表  Y_LNSR  的列名
                //string sql = "select name from syscolumns where id=object_id('" + DropDownList2.SelectedValue + "')";
                //DataSet ds = new DataSet();
                //ds = DBArticle.RunSqlDs(sql);
                //DataRow row = ds.Tables[0].NewRow();
                //row["name"] = "--请选择--";
                //ds.Tables[0].Rows.InsertAt(row, 0);

                //TableCellCollection tcl = e.Row.Cells;//获得表头元素的实例
                //foreach (TableCell item in tcl)
                //{
                //    TableHeaderCell cell = new TableHeaderCell();
                //    DropDownList dro = new DropDownList();
                //    dro.ID = "dro" + i.ToString();
                //    dro.DataSource = ds.Tables[0].DefaultView;
                //    dro.DataTextField = ds.Tables[0].Columns[0].ColumnName;
