How to change the text in a panel

A tricky question is this one:

How can I change the text in an asp:Panel?

Let's assume, a panel like this is given in your ASPX-page:

<asp:Panel ID="thePanel" runat="server">Hi, this is some text</asp:Panel>

Usually, you would start searching for a .Text- or .InnerText-Property. But - and this is the sad news - no such property exists. You don't have the chance to change the panel's text.

Really?

No, of course you can change the text. See the inner text as a LiteralControl and it will work. In your CodeBehind, you'll have to write code like this:

[VB.NET]
Dim objPanelText As LiteralControl = _
   CType(thePanel.Controls.Item(0), LiteralControl)
objPanelText.Text = "Welcome to my VB.NET-page!"

[C#]
LiteralControl objPanelText = thePanel.Controls[0] as LiteralControl;
objPanelText.Text = "Welcome to my C#-page!";

That's it. Really simple, isn't it?

No, this.panel1.text or this.panel1.inertext, that will have been realy simple.

Panel contentOutput = new Panel();

LiteralControl objPanelText = contentOutput.Controls[0] as LiteralControl;

LiteralControl objPanelText = contentOutput as LiteralControl;

None of it works
