I'm sorry, this did not work.

I just tried and the whole thing did post back.

now, it seems that the contentplaceholder is the problem.

I'm i supposed to use any special pattern to solve this?

Hi,

Basically, this should work. Here is a sample:

<%@ Master Language="C#" %>

<!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>
        <asp:ScriptManager ID="ScriptManager1" runat="server">
        </asp:ScriptManager>
         
        <asp:UpdatePanel ID="UpdatePanel1" runat="server">
            <ContentTemplate>
        <asp:contentplaceholder id="ContentPlaceHolder1" runat="server">
        </asp:contentplaceholder>
            </ContentTemplate>
        </asp:UpdatePanel>
    </div>
    </form>
</body>
</html>

<%@ Page Language="C#" MasterPageFile="~/MasterPage2.master" Title="Untitled Page" %>

<script runat="server">

    protected void Button1_Click(object sender, EventArgs e)
    {
        Label1.Text = DateTime.Now.ToString();
    }
</script>

<asp:Content ID="Content1" ContentPlaceHolderID="ContentPlaceHolder1" Runat="Server">
    <asp:Button ID="Button1" runat="server" Text="Button" OnClick="Button1_Click" />
    <asp:Label ID="Label1" runat="server" Text="Label"></asp:Label>
</asp:Content>

The controls inside it are all right.

MasterPage ContentPlaceholder inside Update panel

duditz — Tue, 29 May 2007 20:16:57 GMT

I've created a master page that surrounds a contentplaceholder with an update panel:

asp:updatepanel id="upMain" runat="server"

ContentTemplate

asp:ContentPlaceholder id="mainContent" runat="server"

.../asp:ContentPlaceholder

.../ContentTemplate

.../asp:Updatepanel

The website runs correctly, but every server control inside the content place holder in content pages is underlined and the 'element X is not a known element' error is listed in the Error List window. This applies to all server controls: textboxes, labels, etc.
