asp.net后台怎么读取到RadioButtonList单选框的值

Question

                         像文本框string ID = this.txtID.Text.Trim();这样
                                                    <asp:RadioButtonList ID="RadioButtonList1"  runat="server" RepeatDirection="Horizontal" Width="400px" >
                                   <asp:ListItem Value="1">第一</asp:ListItem>

                                   <asp:ListItem Value="2">第二</asp:ListItem>
                              </asp:RadioButtonList>

Answer 1

刚发的有问题，看这个

RepeatDirection="Horizontal"
RepeatLayout="Flow">


/asp:RadioButtonList

后端获取直接
radioID.SelectedValue
