I would on like AJAX on one content page and want to add an UpdatePanel to the MasterPage and wrap a UserControl that is being loaded from the MasterPage in that UpdatePanel all from the ContentPage. Is it possbile to do this? I have some code but it is not working.

protected override void OnPreInit( EventArgs e )
    {
        ScriptManager sm = new ScriptManager();
        sm.ID = "ScriptManager1";
        Master.Controls.Add( sm );
        UpdatePanel panel = new UpdatePanel();
        panel.ID = "upMaster";
        panel.ContentTemplateContainer.Controls.Add( this.Controls[0] );
        AsyncPostBackTrigger trig = new AsyncPostBackTrigger();
        trig.ControlID = "btnDelete";
        trig.EventName = "Click";
        panel.Triggers.Add( trig );
        Master.Controls.Add( panel );
        base.OnPreInit( e );
    }

        panel.ID = "upMaster";
        UserControl uc = (( UserControl )Master.FindControl( "CartSummary1" ));
        panel.ContentTemplateContainer.Controls.Add( uc );
        panel.
        //AsyncPostBackTrigger trig = new AsyncPostBackTrigger();
        //trig.ControlID = "btnDelete";
        //trig.EventName = "Click";
        //panel.Triggers.Add( trig );
        HtmlForm form1 = ( HtmlForm )Master.FindControl( "Form1" );

        form1.Controls.Add( panel );
        //Master.Controls.Add( panel );
        base.OnPreInit( e );
    }

Yes,It is possible.

Do it like this:

MasterPage.master:

<%@ Master Language="C#" %>
<%@ Register Src="UserControlA.ascx" TagName="UserControlA" TagPrefix="uc1" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<script runat="server">

</script>

<html xmlns="http://www.w3.org/1999/xhtml" >
<head runat="server">
    <title>Untitled Page</title>
</head>
<body>
    <form id="form1" runat="server">
    <div>
        <uc1:UserControlA ID="uc1" runat="server" />
        <asp:contentplaceholder id="ContentPlaceHolder1" runat="server">
        </asp:contentplaceholder>
        <asp:contentplaceholder id="ContentPlaceHolder2" runat="server">
        </asp:contentplaceholder>
    </div>
    </form>
</body>
</html>

Default.aspx:

<%@ Page Language="C#" MasterPageFile="~/MasterPage.master" Title="Untitled Page" %>

<script runat="server">

    protected void Button1_Click(object sender, EventArgs e)
    {
        TextBox1.Text = DateTime.Now.ToString();
    }

    protected void Page_PreInit(object sender, EventArgs e)
    {
        HtmlForm form1 = (HtmlForm)Master.FindControl("form1");
        ScriptManager sm = new ScriptManager();
        sm.ID = "ScriptManager1";
        form1.Controls.AddAt(0, sm);

        UpdatePanel panel = new UpdatePanel();
        panel.ID = "upMaster";
        UserControl uc = ((UserControl)Master.FindControl("uc1"));
        panel.ContentTemplateContainer.Controls.Add(uc);
        form1.Controls.Add(panel);
    }

</script>

<asp:Content ID="Content1" ContentPlaceHolderID="ContentPlaceHolder1" Runat="Server">
    <asp:UpdatePanel ID="UpdatePanel1" runat="server" UpdateMode="Conditional">
        <ContentTemplate>
            <asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
            <div style="display:none;"><asp:Button ID="Button2" runat="server" Text="Button" OnClick="Button1_Click" /></div>
        </ContentTemplate>
    </asp:UpdatePanel>
</asp:Content>

<asp:Content ID="Content2" ContentPlaceHolderID="ContentPlaceHolder2" Runat="Server">
    <script type="text/javascript" language="javascript">
        function doclick(){
            $get('<%= Button2.ClientID%>').click();
        }
    </script>
    <asp:Button ID="Button1" runat="server" Text="Button" UseSubmitBehavior="false" OnClientClick="doclick();return false;" />
</asp:Content>

UserControlA.ascx:

<%@ Control Language="C#" ClassName="UserControlA" %>

<asp:TextBox ID="TextBox1" runat="server">TextBox in UserControlA</asp:TextBox>
