Question

asp.net 一个radiobutton组,怎么得到选择的那个值？

Answer 1

 //.aspx页面
 <asp:RadioButton ID="RadioButton1" runat="server" GroupName="testGroup" Checked="true" Text="RadioButton1"/>
  <asp:RadioButton ID="RadioButton2" runat="server" GroupName="testGroup" Text="RadioButton2"/>
  
  //.cs页面:使用Checked属性做判断
          if (RadioButton1.Checked)
            {
                //选择RadioButton1
            }
            else
            {
                //选择RadioButton1
            }

Answer 2

//.aspx页面
<asp:RadioButton ID="txtu_status1" runat="server" GroupName="testGroup" />正常
<asp:RadioButton ID="txtu_status" runat="server" GroupName="testGroup" />停用
if(u.u_status==1){
txtu_status.Checked = true;
} else {
txtu_status1.Checked = true;
}
//提交按钮直接可以判断
string u_status = txtu_status1.Checked ? "0" : "1";

Answer 3

控件Id.SelectedItem.Text()
