c# - 使用循环在 td 中添加 RadioButtonList 项

Question

在表格单元格之间添加 Asp.net 列表项。当我尝试添加单选按钮列表时，所有列表项都在循环的最后一个 td 中。但我想让它在我的 td inside 循环中成为每个列表项。我在下面附上了代码。我的输出截图如下。谁能帮我解决这个问题。

var noofroom = (from row2 in dt2.AsEnumerable()
                                where (Int64)row2["hotelcode"] == hotelcode
                                     select row2.Field<string>("guests")).Distinct();

                var noofroom2 = (from row3 in dt2.AsEnumerable()
                                where (Int64)row3["hotelcode"] == hotelcode
                                select row3.Field<string>("noofroom")).Distinct();

                int a = 1;

               foreach (var rcount in noofroom)
               {

                    foreach (var rcount2 in noofroom2)
                    {



                        DataRow[] drs = dt2.Select("hotelcode='" + hotelcode + "' AND noofroom='" + rcount2 + "' and guests='"+rcount+"'");
                        int numberOfRecords = dt2.Select("hotelcode='" + hotelcode + "' AND noofroom='" + rcount2 + "' and guests='" + rcount + "'").Length;
                        if (numberOfRecords != 0)
                        {
                            PlaceHolder1.Controls.Add(new LiteralControl("<div class='rhead'>" +

                        }
                        RadioButtonList RadioButtonList1 = new RadioButtonList();
                        RadioButtonList1.ID = hotelcode.ToString() + rcount.ToString()+rcount2.ToString();

                        foreach (DataRow dr in drs)
                        {

Answer 1

将您的数据绑定到网格。使用单选按钮作为项目模板。在 itemtemplate 中指定单选按钮的名称。

尝试这个
