I have a user control with linkbuttons (used for paging) and a repeater inside an update panel. The paging works correctly, but is causing a full page postback every time I click through to the next page.

The update panel looks like this:

<asp:UpdatePanel ID="up1" runat="server" UpdateMode="Always">
        <ContentTemplate>
            <asp:Repeater ID="rptOrganizations" runat="server">
                <HeaderTemplate>
                    <table>
                        <thead>
                            <tr>
                                <th>Organization</th>
                                <th>State</th>
                                <th>Accredited Since</th>
                            </tr>
                        </thead>
                    </table>
                </HeaderTemplate>
                <ItemTemplate>
                    <tr>
                        <td>
                            <asp:Literal ID="ltlInstitution" runat="server" />
                        </td>
                        <td>
                            <asp:Literal ID="ltlState" runat="server" />
                        </td>
                        <td>
                            <asp:Literal ID="ltlAccreditedDate" runat="server" />
                        </td>
                    </tr>
                </ItemTemplate>
                <FooterTemplate>
                    </table>
                </FooterTemplate>
            </asp:Repeater>

            <uc2:RepeaterPaging ID="rpPager" runat="server" PageSize="10" OnNextButtonClickEvent="btnNext_Click" OnPreviousButtonClickEvent="btnPrev_Click" />
        </ContentTemplate>  
    </asp:UpdatePanel>

And the contents of the user control look like this:


                    
                    

                        
                        asp.net
                        
                        updatepanel
                        
                        postback
                        
                        partial-postback
                        
                    

                    

                        
                        
                        
                        
                        
                        Edit
                        
                        
                        

                            
                        

                        
                        Report
