Did you try to set it to null?
handles.listbox1.String = [];

Using a waitbar is not required for clearing a listbox. That's a totally separate issue. Perhaps you cleared it and immediately went into a computationally intensive loop and so the screen did not refresh. To have it refresh immediately, use drawnow.
handles.listbox1.String = [];
drawnow;

ListBoxHandle.Items = {}; %clear the list of items in listbox
edg = errordlg('Message');
waitfor(edg) %program will continue when the dialog box is closed.
drawnow
