RadioButtonList的使用

前臺綁定：
  <asp:RadioButtonList ID="hlBatchYuJi" runat="server" RepeatColumns="1" CellPadding="1" CellSpacing="1">
  </asp:RadioButtonList>

　　

js判斷選中

 var vRbtid = document.getElementById("hlBatchYuJi");
            var vRbtidList = vRbtid.getElementsByTagName("INPUT"); //獲得全部radio
            for (var i = 0; i < vRbtidList.length; i++) {
                if (vRbtidList[i].checked) {
                    BatchText = vRbtid.cells[i].innerText;   //獲取綁定的text值
                    Batchvalue = vRbtidList[i].value;        //獲取綁定的value值
                } 
            }
            if (BatchText == "") {
                alert("請選擇育雛批次！");
                return;
            }

　　

cs文件後臺綁定

 LstBatch = BatchDB.Data.Where(o => o.EnID == UserInfo.EnId && LstChuJIIDs.Contains(o.FarmID) && !LstYiSheBatchID.Contains(o.ID)).ToList();
            hlBatchYuJi.DataSource = LstBatch;
            hlBatchYuJi.DataTextField = "BatchNo";
            hlBatchYuJi.DataValueField = "ID";
            hlBatchYuJi.DataBind();

 

賦值初值，選中的　

var Info = YISheDB.Data.ToInfo(reqID);//根據ID獲取數據
                hlBatchYuJi.Items.Insert(0, new ListItem(Info.BatchNo, Info.BatchID.ToString()));    //插入新的值
                hlBatchYuJi.SelectedIndex = 0;

                foreach (ListItem item in hlFarmJi.Items)                                            //循環判斷選中
                {
                    if (item.Value.ConvertType(0) == Info.FarmID)
                    {
                        item.Selected = true; 
                        break;
                    }
                }
