Solution 3

1. Add GroupName attribute and put same value for both the radio buttons.
for example: GroupName="Gender"
2. Put required field validator.

You can do the same using RadioButtonList as follows:

<asp:radiobuttonlist runat="server" id="radio" xmlns:asp="#unknown">
<%--Creaint Items to be display in Radio Button List--%>
<asp:listitem value="0">Male
<asp:listitem value="1">Female

<%--Creating RequiredFieldValidator control to validate RadioButtonList that we have created--%>

<asp:requiredfieldvalidator runat="server" id="radRfv" controltovalidate="radio" initialvalue="0" errormessage="Select one option" xmlns:asp="#unknown">

Hope this will help you

Following approach can make your life easier
1. Put GroupName="Gender" for both the radio buttons.
2. Keep Male as by default selected.
This way one radio is selected at a time always

Copy following code as it is and check:

<asp:RadioButtonList ID="RadioButtonList1" runat="server">
<asp:ListItem Text="Male" Value="0">
<asp:ListItem Text="Female" Value="1">

<asp:requiredfieldvalidator runat="server" id="radRfv" controltovalidate="RadioButtonList1" errormessage="Select one option">
<asp:Button ID="Button1" runat="server" Text="Button" />
