get value of specific value on item click

[Felice]

I am using the demo radrotator xml live for this project to show rss news.
One of the items in the rss feed is <link> which I am not showing but I would like to use it with the _temClick to open the full article in a radWindow.
This is my actual code:

01.<telerik:RadRotator ID="RadRotator1" RotatorType="AutomaticAdvance" ScrollDirection="Up"
02.                  ScrollDuration="4000" runat="server" Width="714"
03.                  ItemWidth="695" Height="260px" ItemHeight="70" FrameDuration="1" InitialItemIndex="-1"
04.                  CssClass="rotator" OnItemClick="RadRotator1_ItemClick">
05.                  <ItemTemplate>
06.                      <div class="itemTemplate" style="background-image: url('IMAGES3/<%# this.GetDayOfWeek(XPath("pubDate").ToString()) %>.png');">
07.                          <div class="dateTime">
08.                              <div class="time">
09.                                  <%# (this.GetTimeOnly(XPath("pubDate").ToString())) %>
10.                              </div>
11.                              <div class="date">
12.                                  <%# (this.GetDateOnly(XPath("pubDate").ToString()))%>
13.                              </div>
14.                          </div>
15.                          <div class="title">
16.                              <span>
17.                                  <%# System.Web.HttpUtility.HtmlEncode(XPath("title").ToString())%>
18.                              </span>
19.                          </div>
20.                          <div class="buttonDiv">
21.                              <asp:Button ID="Button1" class="button" runat="server" Text="View" OnClientClick="OnClick"  />
22.                              <asp:HiddenField id="rssLink" runat="server" value='<%= System.Web.HttpUtility.HtmlEncode(XPath("link").ToString()%>' />
23.
24.                          </div>
25.                          <div class="description">
26.                              <span>
27.                                  <%# System.Web.HttpUtility.HtmlEncode(XPath("description").ToString())%>
28.                              </span>
29.                          </div>
30.                      </div>
31.                  </ItemTemplate>
32.              </telerik:RadRotator>

I tried with an hiddenfiled to get the value of <link> at row 22 but I cannot get that value in code behind. Then I understood I should use the _itemClick to get the value '<%= System.Web.HttpUtility.HtmlEncode(XPath("link").ToString()%>' but I am really battling to get it.
Please help. How ten I get the value of the rss item <link> of the clicked radRotator item in Radrotatr_itemClicked?
