Putting FileVista control in a Wizard

Under VS 2008 I put a asp.net 2.0 wizard on my page, then put the FileVistaControl in the wizard.  This FVC works if just placed on the page, but when put in the wizard, either via drag-drop or by copying the asp.net into the wizard, it subsequently is deleted.  What is the incompatibility here?

Please view the resulting HTML output and see if the control code is rendered. If so, there may be some javascript error which prevents the control from displaying.
