Drag and Drop Extended ListGrid Class Does Not Display On Palette

I've followed the palette code sample, and tried to apply it to an extended ListGrid without success. However, when dragging and dropping my extended ListGrid object, an exception is raised.

The only workaround I know is to include my extended ListGrid object in a Windows object. If so, I'm able to drag and drop the window from a palette into an edit pane.
