In this step, you will add a WijExpander control to associate with the Panel to create the expanding text.
While still in Source view, use the following markup toadd a WijExpander control to the page and set the TargetControlID to Panel1.
<cc1:WijExpander ID="Panel1_WijExpander" runat="server"
TargetControlID="Panel1">
</cc1:WijExpander>
Now you can begin setting properties for the WijExpander to format the expanding text.
