I have built a 4-option radio button group:
        <asp:Panel ID="Panel3" Class="Panel3" runat="server" >&nbsp
             <asp:RadioButton  name="location" Text="SA" runat="server" style="font-family: Arial; font-size: small" />&nbsp
            <asp:RadioButton name="location" Text="Med Ctr" runat="server" style="font-family: Arial; font-size: small" />&nbsp&nbsp
            <asp:RadioButton name="location" Text="MOB" runat="server" style="font-family: Arial; font-size: small" />&nbsp&nbsp
            <asp:RadioButton name="location" Text="RA" runat="server" style="font-family: Arial; font-size: small" />&nbsp
            
        </asp:Panel>

Open in new window


Question: Why selecting one option doesn't uncheck the previousely selected option?

Thank you.

Because you need to give each one the same GroupName attribute in order for them to act as a group:
<asp:Panel ID="Panel3" Class="Panel3" runat="server" >&nbsp
             <asp:RadioButton  name="location" Text="SA" runat="server" style="font-family: Arial; font-size: small"  GroupName="Location" />&nbsp
            <asp:RadioButton name="location" Text="Med Ctr" runat="server" style="font-family: Arial; font-size: small" GroupName="Location" />&nbsp&nbsp
            <asp:RadioButton name="location" Text="MOB" runat="server" style="font-family: Arial; font-size: small" GroupName="Location" />&nbsp&nbsp
            <asp:RadioButton name="location" Text="RA" runat="server" style="font-family: Arial; font-size: small"  GroupName="Location" />&nbsp
        </asp:Panel>

Thank you. Works great.

I wonder if you could help me also with

making this group disable and option Text="Med Ctr" selected.

Later on they may all be active.

Regards,

Mike

To manipulate the radiobutton in code you need to give it an ID:
<asp:RadioButton name="location" Text="Med Ctr" runat="server" style="font-family: Arial; font-size: small" GroupName="Location" ID="MedRadio" />

Open in new window

You can then select it through code:
MedRadio.Checked = true;

Open in new window

To disable all of the radio buttons you simply need to disable the panel which houses them:
Panel3.Enabled = false;

Open in new window

How about selecting one of the options, for example:

selecting option Text="Med Ctr" selected.

Thanks.
