My webpart contains a dropdown list and linkbuttons. Dropdown list becomes
empty when i use the update panel. Any solutions to this ?

Maybe this will help.  You can instantly make a webpartzone and all of the
webparts in it asyncronous without writing any code or making changes to
individual webparts.  Check out the April 2nd blog entry.

As for the dropdown make sure to set autopostback=true unless of course you
have some button or similar on the webpart to process the changes.

Good Luck

I was placing the updatepanel inside the webpartzone due to which the
webpart was crashing. The autopostback property were true in both the cases.

<asp:WebPartZone ID="WebPartZone1" runat="server" Height="68px"
Mozilla:WebPartVerbRenderMode="TitleBar">
                            <ZoneTemplate>
                                 <atlas:UpdatePanel ID="myUpdate1"
runat="server" Mode="Always">
                                     <ContentTemplate>
                                        <WPControls:ShoppingCartControlWP
ID="_ShoppingCartControlWP" runat="server" />
                                     </ContentTemplate>
                                </atlas:UpdatePanel>
                             </ZoneTemplate>
                         </asp:WebPartZone>


That's why the dropdownlist and other contents were coming empty. But now
when I wrapped the webpartzone with the updatepanel the contents are getting
loaded.

<atlas:UpdatePanel ID="myUpdate1" runat="server" Mode="Always">
                  <ContentTemplate>
                        <asp:WebPartZone ID="WebPartZone1" runat="server"
Height="68px" Mozilla:WebPartVerbRenderMode="TitleBar">
                            <ZoneTemplate>
                                 <WPControls:ShoppingCartControlWP
ID="_ShoppingCartControlWP" runat="server" />
                             </ZoneTemplate>
                         </asp:WebPartZone>
                 </ContentTemplate>
         </atlas:UpdatePanel>

but there is error that popsup now...

Assertion Failed: Duplicate use of id "WebPart__ShoppingCartControlWP" for
object of type "Sys.UI.Controls.WebParts.WebPart".
