从中继器访问所有RadioButton

Question

I have a Repeater of RadioButton . Is there an easy way to access all these RadioButton from the C# side? For example, maybe access by the GroupName ? I couldn't find anything simple online.

ASPX:

<asp:Repeater ID="rptOtherNetworks" runat="server" >
    <HeaderTemplate>
        <li data-theme="c" data-role="list-divider" class="ui-li ui-li-divider ui-bar-b">
            <asp:Localize ID="locRecentlySelected" runat="server"
                EnableViewState="False" meta:resourcekey="locRecentlySelectedResource1"
                Text="Select Network from Other Cameras">
            </asp:Localize>
        </li>
    </HeaderTemplate>
    <ItemTemplate>
        <li data-theme="c">
            <!-- I want to access these -->
            <asp:RadioButton Text='<%# Eval("NetworkDescription") %>' data-mac='<%# Eval("MAC") %>'
                Checked="False" GroupName="RadioGroupNetworkCameras" runat="server" />
        </li>
    </ItemTemplate>
</asp:Repeater>

Well, you can retrieve all of the RadioButtons by finding them by their ID in each of the RepeaterItems.

<asp:RadioButton ID="rb"
    Text='<%# Eval("NetworkDescription") %>'
    data-mac='<%# Eval("MAC") %>'
    Checked="False"
    GroupName="RadioGroupNetworkCameras"
    runat="server" />

foreach (RepeaterItem ri in rptOtherNetworks.Items)
{
    if (ri.ItemType == ListItemType.Item || ri.ItemType == ListItemType.AlternatingItem)
    {
        RadioButton r = (RadioButton)ri.FindControl("rb");
    }
}

But a problem you are going to run into is that within the Repeater, the radio buttons will not be mutually exclusive . There are various ways of "fixing" this through JavaScript and other methods, but just be aware this.
