    I did not see a method for it, and this is kind of sloppy looking by the way the control draws, but it is one way of handling it.

    Where List_XLS would be your userform, and lstXLS would be your TcxListBox, and chkAll would be your checkbox with the OnClick handler of function "checkedall":

     

    function checkedall(sender) {
        /*
          make sure multiselect is enabled
        */
        UserForms.List_XLS.lstXLS.MultiSelect = true;
        
        /*
          if checked then set selected of each item in the listbox
        */
        if (UserForms.List_XLS.chkAll.Checked){
          for (var c = 0; c < UserForms.List_XLS.lstXLS.Items.Count;c++) {
            UserForms.List_XLS.lstXLS.Selected(c) = true;
          }
        }
        
        /*
          if checked then remove selected of each item in the listbox
        */
        if (!UserForms.List_XLS.chkAll.Checked) {
          for (var c = 0; c < UserForms.List_XLS.lstXLS.Items.Count;c++) {
            UserForms.List_XLS.lstXLS.Selected(c) = false;
          }
        }
    }
