    Hi
    I have written a code for showing the list boxes as selected using a
    Listitem and the selected property of the items.
    Now I have 2 list boxes in my page. But it shows only the selected values
    of the last list box in both the list boxes.
    If i reverse the calls to the filllistbox methods it shows the value
    selected for the 1st list box in both the listboxes.
    I have the code for my method below. Is there a way I can solve this
    problem?

    The method calls are as follows :-

    this.FillListBox(myModel.CustomerLBUserList, myModel.SelectedPRList,
    this.lstProofreaders);

    this.FillListBox(myModel.CustomerLBUserList, myModel.SelectedRevList,
    this.lstReviewers);


    Thanks in advance
