asp.net后台怎么读取到RadioButtonList单选框的值

                         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>

刚发的有问题，看这个

RepeatDirection="Horizontal"
RepeatLayout="Flow">


/asp:RadioButtonList

后端获取直接
radioID.SelectedValue

/asp:RadioButtonList
后端获取直接
rdbPT_SJFAIsPass.SelectedValue

(⊙o⊙)…无语怎么会有部分看不到了呢，看最后两行吧，相信以你的IQ能看懂的，哈哈

string value=RadioButtonList1.SelectedValue ;
可以取得你选择的选项
