Custom Control not displaying text in Designer

[Earl Teigrob]

I can create a new custom control (and not change it) and add it to the
toolbox and drag it onto the disign screen and it works just fine,
displaying the text [WebCustomControl]. However, when I add the following
datepicker control to the toolbox, it just shows a yellow dot and thats it.
What happened to the text???
