Hi,
How can I update the html inside of a panel?

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

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

{
Panel1.innerHTML = "<html>Hello World!!!<html>"; //This will not
work.
}
</script>

A Panel is rendered on the client by a DIV. You can see that by viewing
the HTML source sent to the client, always a good idea when something is
not working properly.

Since the Panel is a DIV, you may not use the "html" tags again, as they
are already present in the document.

You could use a Literal instead of a panel and set the Text property of the
literal;

MyLiteral.Text = "<p>Hello world</p>";
 
Hi flyguy,

I can see your intension is to mark the "Hello World!!!" as html, therefore
you enclosed it in tag "<html></html>".

First, innerHTML is not a server-side property, it's a client-side property
(http://msdn2.microsoft.com/en-us/library/ms533897.aspx). You can use any
html source to set to this property, for example: <h1>Hello World!!!</h1>.
However, "<html></html>" is also a valid html tag which normally used in
the most outside of the html source.

To set the html inside the Panel at server-side, you can create a literal
control with the html source and add the control to the Panel:

LiteralControl lc = new LiteralControl("<h1>Hello World!!!</h1>");
panel1.Controls.Add(lc);


To set the html inside the Panel at client-side, you can use:

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs"
Inherits="_Default" %>

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

<html xmlns="http://www.w3.org/1999/xhtml" >
<head runat="server">
<title>Untitled Page</title>
<script type="text/javascript" language="javascript">
function test()
{
var panel2 = document.getElementById('panel2');
panel2.innerHTML = "<h1>Hello JavaScript!!!</h1>";
}
</script>
</head>
<body>
<form id="form1" runat="server">
<div>
<asp:Panel ID="panel1" runat="server"></asp:Panel>
<asp:Panel ID="panel2" runat="server"></asp:Panel>
<input type="button" onclick="test()" value="test" />
</div>
</form>
</body>
</html>


Hope this helps.
