I hope someone can help. My asp.net application is exhibiting strange behaviour. Whenever I press the Return/Enter key I get a series of beeps/dings. It sort of goes dindindidindindinggggg !

I have reproduced the issue with a small sample application:

<%@ Page Language="Oxygene" AutoEventWireup="true"  CodeFile="Default.aspx.pas" Inherits="_Default" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN" "http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd">

<html xmlns="http://www.w3.org/1999/xhtml" >
<head runat="server">
    <title>Untitled Page</title>
</head>
<body>
    <form id="form1" runat="server">
        <asp:TextBox ID="TextBox1" runat="server">
        </asp:TextBox>
        <asp:TextBox ID="TextBox2" runat="server">
        </asp:TextBox>
    </form>
</body>
</html>

This only happens in IE, in firefox and chrome there is no beeping.

Also as a side issue, if I remove one of the textboxes then there is no dinging but I get a post back instead.

Anyone know what is going on here?

Thanks,

AJ

    I found the answer:

    <%@ Page Language="Oxygene" AutoEventWireup="true"  CodeFile="Default.aspx.pas" Inherits="_Default" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN" "http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd">

    <html xmlns="http://www.w3.org/1999/xhtml" >
    <head runat="server">
        <title>Untitled Page</title>
    </head>
    <body onkeypress="if(event.keyCode==13)return false;">
        <form id="form1" runat="server" onsubmit="return false;">
            <asp:TextBox ID="TextBox1" runat="server">
            </asp:TextBox>
            <asp:TextBox ID="TextBox2" runat="server">
            </asp:TextBox>
        </form>
    </body>
    </html>

    This stops the beeping and stops a post-back when only a single input element.
