    I have one combobox and two radlistboxes. The first listbox's datasource is changed when the comboboxes' selecteditemindex changes.

    When I do the following:

    Change combobox, pick two items from the first listbox and add them to the second listbox.
    Change combobox again and pick another item and add it to the second listbox.

    The items inside the second listbox are empty now.

    Is there a workaround for this or am I doing something wrong (like resetting datasource or postback or so?).

    I created a sample page with the explained functionality, and everything seems to work fine. You can preview the attached page and compare it with your project.
