    • with a head tag with runat="server"
    • inside a form tag with runat="server"
    • before the ContentPanels that contain controls that require it - typical controls with UpdatePanels:

    <%=PageTitle%> 

    </form>
 </body>

    It simply wants the ASP control on your ASPX page. I usually place mine right under the tag, or inside first Content area in the master's body (if your using a master page)

    <body>
    <form id="form1" runat="server">
        <asp:ScriptManager ID="scriptManager" runat="server"></asp:ScriptManager>
        <div>
            [Content]
        </div>
    </form>
</body>

    If you are using microsoft ajax on your page you need the script manager control added to your master page or the page that needs it. It Manages ASP.NET Ajax script libraries and script files, partial-page rendering, and client proxy class generation for Web and application services

    <asp:ScriptManager ID="ScriptManger1" runat="Server">
</asp:ScriptManager>

    The full usage

    <asp:ScriptManager
    AllowCustomErrorsRedirect="True|False"
    AsyncPostBackErrorMessage="string"
    AsyncPostBackTimeout="integer"
    AuthenticationService-Path="uri"
    EnablePageMethods="True|False"
    EnablePartialRendering="True|False"
    EnableScriptGlobalization="True|False"
    EnableScriptLocalization="True|False"
    EnableTheming="True|False"
    EnableViewState="True|False"
    ID="string"
    LoadScriptsBeforeUI="True|False"
    OnAsyncPostBackError="AsyncPostBackError event handler"
    OnDataBinding="DataBinding event handler"
    OnDisposed="Disposed event handler"
    OnInit="Init event handler"
    OnLoad="Load event handler"
    OnPreRender="PreRender event handler"
    OnResolveScriptReference="ResolveScriptReference event handler"
    OnUnload="Unload event handler"
    ProfileService-LoadProperties="string"
    ProfileService-Path="uri"
    RoleService-LoadRoles="True|False"
    RoleService-Path="uri"
    runat="server"
    ScriptMode="Auto|Inherit|Debug|Release"
    ScriptPath="string"
    SkinID="string"
    SupportsPartialRendering="True|False"
    Visible="True|False">
        <AuthenticationService
            Path="uri" />
        <ProfileService
            LoadProperties="string"
            Path="uri" />
        <RoleService
            LoadRoles="True|False"
            Path="uri" />
        <Scripts>
            <asp:ScriptReference
                Assembly="string"
                IgnoreScriptPath="True|False"
                Name="string"
                NotifyScriptLoaded="True|False"
                Path="string"
                ResourceUICultures="string"
                ScriptMode="Auto|Debug|Inherit|Release" />
        </Scripts>
        <Services>
            <asp:ServiceReference
                InlineScript="True|False"
                Path="string" />
        </Services>
</asp:ScriptManager>

    On the ASP.NET page, inside the form tags.

    The ScriptManager is a web control that you register in the page using

    <asp:ScriptManager ID="ScriptManger1" runat="Server" />

    inside the Form tag

    The ScriptManager is a control that needs to be added to the page you have created.

    Take a look at this Sample AJAX Application.

    <body>
    <form runat="server">
        <asp:ScriptManager ID="ScriptManager1" runat="server"></asp:ScriptManager>
        ...
    </form>
</body>
