Visual Studio .NET - ASP.NET Ajax Update Panel in ContentPlaceHolder

Asked By c g

12-Feb-07 11:20 AM

Hi,
I have a ScriptManager and UpdatePanel as below

<asp:Content ID="Content1" ContentPlaceHolderID="MainContent" Runat="Server">

<asp:ScriptManager ID="ScriptManager1" runat="server">

</asp:ScriptManager>

<asp:UpdatePanel ID="UpdatePanel1" runat="server">

<uc1:SecurityFloatingCharge runat="server" ID="uctrSecurityFloatingCharge" />

</ContentTemplate>

</asp:UpdatePanel>

</asp:Content>

When I run my page I get an error stating "Sys.WebForms.PageRequestManagerParserErrorException : The message received from the server could not be parsed. Common causes for this error are when the response is modified by calls to Response.Write(), response filters, httpModules, or server trace is enabled. Details: Error parsing near 'et>"

When I don't use a Master Page and have my aspx like below without a ContentPlaceholder it works fine. Anyone know why?

<title>Partial-Page Update Error Handling Example</title>

</head>

<body>

<div>

<asp:ScriptManager ID="ScriptManager1" runat="server">

</asp:ScriptManager>

<asp:UpdatePanel ID="UpdatePanel1" runat="server">

<uc1:SecurityFloatingCharge runat="server" ID="uctrSecurityFloatingCharge" />

</ContentTemplate>

</asp:UpdatePanel>

</div>

</form>

</body>

</html>

steps for Using the ASP.NET UpdatePanel Control with Master Pages

Using the ASP.NET UpdatePanel Control with Master Pages

Any ASP.NET page that includes an http://ajax.asp.net/docs/mref/T_System_Web_UI_UpdatePanel.aspx control also requires a http://ajax.asp.net/docs/mref/T_System_Web_UI_ScriptManager.aspx control. To use http://ajax.asp.net/docs/mref/T_System_Web_UI_UpdatePanel.aspx controls with master pages, you can put a http://ajax.asp.net/docs/mref/T_System_Web_UI_ScriptManager.aspx control on the master page. In this scenario, the master page provides a http://ajax.asp.net/docs/mref/T_System_Web_UI_ScriptManager.aspx control for every content page. If you do not want partial-page updates enabled for individual content pages, you can disable partial-page updates for those pages.

Alternatively, you can put the http://ajax.asp.net/docs/mref/T_System_Web_UI_ScriptManager.aspx control on each content page. You might do this if only some of the content pages will contain http://ajax.asp.net/docs/mref/T_System_Web_UI_UpdatePanel.aspx controls.

You can see the code in action in this tutorial by clicking the Run It buttons. To implement the procedures in your own development environment you need:

Visual Web Developer Express Edition or Microsoft Visual Studio 2005.
The latest release of Microsoft ASP.NET AJAX installed and configured. For more information, see http://ajax.asp.net/docs/InstallingASPNETAJAX.aspx.
An ASP.NET AJAX Web site

Thanks. That works.
