<asp:content id="subscriptioncontent" contentplaceholderid="maincontent" viewstatemode="enabled" runat="server">     <asp:panel id="subscriptionpanel" cssclass="shopping-cart" viewstatemode="enabled" runat="server">         <asp:listview id="newsubscription" runat="server">             <layouttemplate>                 <table class="table">                     <thead>                         <th>select subscription</th>                         <th>subscription level                         </th>                         <th>description                         </th>                         <th>price                         </th>                     </thead>                     <tbody>                         <tr id="itemplaceholder" runat="server" />                     </tbody>                 </table>             </layouttemplate>             <itemtemplate>                 <tr>                     <td class="description"><asp:radiobutton id="subscriptionlevel" groupname="subscriptionradio" text='<%# eval("subscriptionlevel") %>' runat="server" /></td>                     <td class="description"><asp:label id="details" text='<%# eval("details") %>' runat="server"></asp:label></td>                     <td class="price"><asp:label runat="server" text='<%# eval("price", "{0:c2}") %>'></asp:label></td>                     <asp:textbox id="id" runat="server" visible="false" text='<%# eval("id") %>' />                 </tr>             </itemtemplate>         </asp:listview>          <asp:button id="subscribe" cssclass="btn btn-primary" runat="server" text="<%$ snippet: ecommerce/shoppingcart/checkoutbuttonlabel, checkout %>" onclick="buysubscription" />         <script type="text/javascript">             $(document).ready(function () {                 $("input:radio").attr('name', 'subscriptionradio');//override naming asp                                });         </script>     </asp:panel> </asp:content> 

i thinking if update hidden field corresponding guid value each radio button , submit when user triggers buysubscription. not sure how though. want user able select 1 of subscription options , pass guid function.

thank in advance input.

the first problem you're going run asp.net gives each <input type="radio" /> different name, because it's in different namingcontainer.

you've added script try work around changing name attribute on client. unfortunately, won't work. when post form server, asp.net still looking value using generated name, won't exist.

the quick , dirty solution update script copy value hidden textbox value attribute of radiobutton. have use request.form["subscriptionradio"] retrieve value of selected option:

<itemtemplate>     <tr>         <td class="description">             <asp:radiobutton id="subscriptionlevel" runat="server"                 groupname="subscriptionradio"                  text='<%# eval("subscriptionlevel") %>'              />             <%-- nb: can't set visible="false", otherwise it's not rendered: --%>             <asp:textbox id="id" runat="server"                  style="display:none;"                 text='<%# eval("id") %>'              />         </td>         ...     </tr> </itemtemplate> ... <script> $(document).ready(function() {     $("input:radio").each(function(){         var me = $(this);         var id = me.closest("tr").find("input[name$=id]").val();         me.attr("value", id);         me.attr('name', 'subscriptionradio');     }); }); </script> 

alternatively, use custom radiobutton control works within data-bound control. posted simple example in 2012: https://stackoverflow.com/a/13271444/124386

using system; using system.collections.specialized; using system.componentmodel; using system.reflection; using system.web.ui; using system.web.ui.webcontrols;  namespace sitecontrols {     [toolboxdata("<{0}:listradiobutton runat=\"server\" />")]     public class listradiobutton : radiobutton     {        private static readonly fieldinfo uniquegroupnamefield = finduniquegroupnamefield();        private string _uniquegroupname;         private static fieldinfo finduniquegroupnamefield()        {           return typeof(radiobutton).getfield("_uniquegroupname",               bindingflags.nonpublic | bindingflags.instance);        }         public string value        {            { return attributes["value"]; }            set { attributes["value"] = value; }        }         protected virtual string createuniquegroupname()        {           string result = groupname;           if (string.isnullorempty(result))           {              result = id;           }           if (string.isnullorempty(result))           {              result = uniqueid;           }           else           {              control container = namingcontainer;              if (container != null)              {                 if (container idataitemcontainer)                 {                    container = container.namingcontainer ?? container;                 }                  result = container.uniqueid + base.idseparator + result;              }              else              {                 string uniqueid = uniqueid;                 if (!string.isnullorempty(uniqueid))                 {                    int index = uniqueid.lastindexof(base.idseparator);                    if (index != -1)                    {                       result = uniqueid.substring(0, 1 + index) + result;                    }                 }              }           }            return result;        }         private void ensureuniquegroupname()        {           if (_uniquegroupname == null)           {              string value = createuniquegroupname();              if (uniquegroupnamefield != null) uniquegroupnamefield.setvalue(this, value);              _uniquegroupname = value;               value = base.attributes["value"];              if (string.isnullorempty(value))              {                 base.attributes["value"] = uniqueid;              }           }        }         protected override bool loadpostdata(string postdatakey, namevaluecollection postcollection)        {           ensureuniquegroupname();           return base.loadpostdata(postdatakey, postcollection);        }         protected override void render(htmltextwriter writer)        {           ensureuniquegroupname();           base.render(writer);        }     } } 

you can either register control in page markup:

<%@ register tagprefix="site" namespace="sitecontrols" %> 

or in web.config file:

<?xml version="1.0"?> <configuration>     <system.web>         <pages>             <controls>                 <add                      tagprefix="site"                      namespace="sitecontrols"                 />             </controls>         </pages>     </system.web> </configuration> 

with in place, can lose script , hidden textbox:

<itemtemplate>     <tr>         <td class="description"><site:listradiobutton id="subscriptionlevel" runat="server"             groupname="subscriptionradio"              text='<%# eval("subscriptionlevel") %>'             value='<%# eval("id") %>'         /></td>         ... 

to find selected item, need loop through listview's items, find radiobutton control, , @ checked property:

listradiobutton selecteditem = newsubscription.items     .select(item => (listradiobutton)item.findcontrol("subscriptionlevel"))     .firstordefault(radio => radio != null && radio.checked);  string selectedvalue = (selecteditem == null) ? null : selecteditem.value;
