How to check one radio button out of two in vb.net - vb.net

Question

Suppose I have 2 radio buttons r1 and r2, both the radio buttons ask for your gender, you can be a man or woman.
So what I want: if user checks r1 but then realizes that she is a woman, she then wants to check r2 so the control on r2 gets checked while r1 gets unchecked.
<tr>
<td>
<asp:Label runat="server" text="Chooose Your Category" ID="lblcategory"></asp:Label>
</td>
<td>
<asp:RadioButton runat="server" Text="Male" ID="rbgold" />
</td>
<td>
<asp:RadioButton runat="server" Text="Female" ID="rbsilver" />
</td>
</tr>
What should I do next so as I can choose only one?
Thanks in advance.

Answer 1

Just give the two asp:RadioButtons the same GroupName
As MSDN notes,
Use the GroupName property to specify a grouping of radio buttons to
create a mutually exclusive set of controls. You can use the GroupName
property when only one selection is possible from a list of available
options.
When this property is set, only one RadioButton in the specified group
can be selected at a time.
Example:
<tr>
<td>
<asp:Label runat="server" text="Chooose Your Category" ID="lblcategory">
</asp:Label>
</td>
<td>
<asp:RadioButton runat="server" Text="Male" ID="rbgold" GroupName="GenderGroup" />
</td>
<td>
<asp:RadioButton runat="server" Text="Female" ID="rbsilver" GroupName="GenderGroup" />
</td>
</tr>

Answer 2

You need to put them in the same group so that only one can be selected at a time, something like:
<asp:RadioButton runat="server" Text="Male" ID="rbgold" GroupName="xyzzy" />
<asp:RadioButton runat="server" Text="Female" ID="rbsilver" GroupName="xyzzy" />

Answer 3

Raghav Chopra: There is no need of RadioButtonList for this issue,you only put the radio buttons in same group then only one is selected at a time,and also your problem is solved

Answer 4

I got my answer by using an asp:RadioButtonList
<tr>
<td>
<asp:Label runat="server" text="Chooose Your Category" ID="lblcategory">
</asp:Label>
</td>
<td class="style1">
<asp:RadioButtonList ID="rbgold" runat="server"
RepeatColumns="2"
Width="200px">
<asp:ListItem Text="Silver class" value="1" ></asp:ListItem>
<asp:ListItem Text="Gold class" value="2"></asp:ListItem>
</asp:RadioButtonList>
</td>
</tr>
