In this topic you add some content to a Panel control that will later become a dialog box.

1. In your Web application, add a standard Panel control to the main content of  your page.
2. Add some content for the dialog box. For example:

<asp:Panel ID="Panel1" runat="server" Width="845px">

     <h2>Dialog Box</h2>

        <br />

        <span>This is the default dialog which is useful for displaying information. The dialog window can be moved, resized and closed with the 'x' icon.</span>

</asp:Panel>

2. Next add a C1DialogExtender control to the page.
