라디오 버튼 목록 및 라디오 버튼 asp.net

Question

내 코드는 다음과 같습니다. 여기에 하나만 rdbtn5 또는 하나의 라디오 목록 item.But 중 하나를 선택해야하는 문제가 있습니다. 그러나 둘 다 선택할 수 있습니다. 제발 제안 해주세요.

<table width="100%" border="0" cellspacing="0" cellpadding="0"> 
     <tr> 
      <td width="70%" style="padding-left:10px; text-decoration-color:white"> 
       <div class="content" style="display: inline-block !important;"> 
        <asp:RadioButton ForeColor="White" ID="rdContribute" AutoPostBack="true" OnCheckedChanged="rdContribute_CheckedChanged" Text="abc"<br/> GroupName="RadioGroup1" runat="server" /><!--onchange="Monthly()" --> 

        <div style="display:block;margin-left:10px;" id="dvrdList"> 
        <asp:RadioButtonList ID="rdlist" ForeColor="White" GroupName="Selected1" runat="server">        
          <asp:ListItem Text="Rs.100/month(Rs.1200/Year)" Value="100" name="abc" Selected="True"></asp:ListItem>        
          <asp:ListItem Text="R.250/month(Rs.3000/Year)" Value="250" name="abc"></asp:ListItem> 
          <asp:ListItem Text="Rs.500/month(Rs.6000/Year)" Value="500" name="abc"></asp:ListItem>  
         <asp:ListItem Text="Rs.1000/month(Rs.12000/Year)" Value="1000" name="abc"></asp:ListItem> 
          <asp:ListItem Text="Rs.5000/month(Rs.60000/Year)" Value="5000" name="abc"></asp:ListItem> 

         </asp:RadioButtonList> 

         <asp:RadioButton runat="server" ID="rdbtn5" name="abc" AutoPostBack="true" OnCheckedChanged="rdContribute_CheckedChanged" GroupName="Selected1"/><asp:TextBox ID="tbGreater" runat="server" onkeypress="return isNumberKey(event)" CausesValidation="true" Enabled="false"></asp:TextBox> 
         <asp:RangeValidator ID="RangeValidator1" Type="Integer" MinimumValue="1000" MaximumValue="1000000" ControlToValidate="tbGreater" runat="server" ErrorMessage="Enter digits greater than 1000"></asp:RangeValidator> 

        </div> 
        <asp:RadioButton ForeColor="White" ID="rdNo" AutoPostBack="true" Text="I do not wish to make a contribution" OnCheckedChanged="rdNo_CheckedChanged" GroupName="RadioGroup1" runat="server" />   

       </div> 
      </td> 

     </tr> 
     <tr> 
      <td> 
       <asp:RadioButton ForeColor="White" ID="rdReminder" AutoPostBack="true" name="rdReminder" Visible="false" OnCheckedChanged="rdReminder_CheckedChanged" Text="def" GroupName="RadioGroup1" runat="server" /> 
      </td> 
    </table> 

Answer 1

RadioButtonList OnSelectedIndexChanged에 추가하십시오.

protected void rdlist_CheckedChanged(object sender, EventArgs e) 
    { 
     //uncheck all checkboxes 
     rdbtn1.Checked = false; 
     rdbtn2.Checked = false; 
     rdbtn3.Checked = false; 
     rdbtn4.Checked = false; 
     rdbtn5.Checked = false; 
    } 

이 한 번만 작동

protected void globalRadio_SelectedIndexChanged(object sender, EventArgs e) 
    { 
     //uncheck all checkboxes 
     rdbtn1.Checked = false; 
     rdbtn2.Checked = false; 
     rdbtn3.Checked = false; 
     rdbtn4.Checked = false; 
     rdbtn5.Checked = false; 

     //uncheck all checkboxes in the list 
     foreach (ListItem listItem in rdlist.Items) 
     { 
      listItem.Selected = false; 
     } 

     //re-check the clicked radiobutton 
     RadioButton rb = sender as RadioButton; 
     rb.Checked = true; 
    }
