Default AJAX with googleMaps


I am creating a store locator that displays a large map on page load and searches for stores when a user enters postcode/city.
Next to the map there is a listview of the store details with the datapager.
When I click the pager buttons, the map gets reloaded, and I don't want that. I tried using script manager in various places in the script but it seems to prevent the small map (and sometimes storelist) from displaying. Can anyone help me with this please?

Here is the code (simplified, as there is quite a lot)

HTML Code:
<div class="container storelocator">
            <div class="row">
                <div class="col-md-12">
                    <h2>Store locator</h2>
                 <div class="col-md-6 storemap">
                        <div class="form-group">
                            <div class="input-group">
                                <asp:TextBox ID="TxBxTownPostcode"
runat="server" CssClass="form-control" placeholder="Enter your town or postcode"></asp:TextBox>
                                <span class="input-group-btn">
                                    <asp:Button ID="storeLocatorBtn" runat="server" CssClass="btn btn-default storeLocatorBtn" Text="Go!" OnClick="storeLocatorBtn_Click1" />

                        <asp:PlaceHolder ID="smallStoreMapPlcHldr" runat="server" Visible="false">   
                           <div id="map-canvas"></div>      

                    <asp:PlaceHolder ID="bigStoreMapPlcHldr" runat="server" Visible="true">
                            <div class="container">
                                <div class="row">
                                    <div class="col-md-12">
                                         <div id="map-canvas-big"></div>

                <asp:PlaceHolder ID="storelistPlcHldr" runat="server" Visible="false">
                  <div class="col-md-6 storelist">
                    <asp:ListView ID="storeList" runat="server" DataKeyNames="id" OnPagePropertiesChanging="storeList_PagePropertiesChanging" OnItemDataBound="storeList_ItemDataBound">
                            <table id="storeListTbl" cellpadding="2">
                                <tr id="itemPlaceholder" runat="server">
                            <asp:DataPager runat="server" ID="DataPager1" PageSize="3" PagedControlID="storeList">
                                   <asp:NextPreviousPagerField ButtonType="Link" ShowFirstPageButton="false" ShowPreviousPageButton="true"
                                        ShowNextPageButton="false" />
                                    <asp:NumericPagerField ButtonType="Link" />
                                    <asp:NextPreviousPagerField ButtonType="Link" ShowNextPageButton="true" ShowLastPageButton="false" ShowPreviousPageButton="false" />

Hard to say without knowing a lot more about your setup. Since this isn't related to my book directly, I would recommend posting this in the general ASP.NET category here: http://p2p.wrox.com/asp-net-4-5-709/ and provide more information. That might attract others too that can hopefully help you out.
