I have the following rotator
<telerik:RadRotator ID="RadRotator1b" runat="server"  Height="190px" width="880px" BackColor="#a6ce39"    
                                                              RotatorType="ButtonsOver" ItemHeight="100px" ItemWidth="165px"  Skin=""   cssclass="RadRotator_rotatorSkin"  ScrollDuration="350"  FrameDuration="800" > 
                                                        <ItemTemplate> 
                                                          <div class="itemTemplate">  
                                                             
                                                             <table style='margin:1px 1px 1px 1px;background-color:transparent;padding:0;border:none;cursor:pointer;width:100%;-moz-border-radius:1px;-webkit-border-radius:1px;' > 
                                                                            <tr><td  style="width:10%">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;</td><td  style="width:80%"><href='<%# XPath("link") %>' target="_blank" style="width:100%">  
                                                                                 <img src='<%# XPath("src") %>'  border='0' hspace='0' width='90' height='130' align='center'/>  </a></td>  
                                                                              <td  style="width:10%">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;</td></tr>  
                                                                          <tr><td style="width:100%" colspan='3' align="center">    
                                                                              <href='<%# XPath("link") %>' style='font-weight: bold; font-size: 8pt; color: #484849;'><%# XPath("title") %> </a></font</td></tr>  
                                                                           <tr><td style="width:100%; color:White; " colspan='3' align="center">    
                                                                          <%#XPath("t")%>&nbsp;</asp:Label><a href='http://www.neelwafurat.com/locate.aspx?mode=1&search=author1&entry=<%# XPath("author") %>' style='font-size: 8pt; color: white;'><%#XPath("author")%> </a></font>   
                                                                             </td></tr>  
                                                                        </table> 
                                                       
                                                                   
                                                                
                                                        </div> 
                                                        </ItemTemplate> 
                                                    </telerik:RadRotator> 
                                                    <asp:XmlDataSource ID="XmlDataSourceb1" runat="server" XPath="books/book"  DataFile="~/generated_files/bitems.xml" ></asp:XmlDataSource> 

I am not setting the datasourceid to be XmlDatasourceb1 because i want to set it from javascript function.I need the items to load on tabclick event.This rotator is inside a pageview of a tab.How can i do that?Is it possible to set datasourceid from javascript?

Hi Maha,

DataSourceID property of ASP.NET controls is a server-side property and it cannot be set by JavaScript on the client. For the time being RadRotator control does not provide client-side API that can be used in order to add items client-side, but we will do our best to implement such feature for the future releases of the control. We have made the first step by adding lazy loading for the Rotator's items. This new feature will be officially available in the upcoming Q2 2010 release of the control, but you can test it in the recent Q2 2010 BETA release.

Kind regards,
Fiko

i was able to do that by using RadXmlHttpPanel and putting the rotator inside it.By doing that i was able to load items into rotator without reloading the page.
