UserForms- TcxListBox Question

Hi ,

This might be a simple task but i am having hard time selecting all items of TcxListBox at run time if a user checks on the checkbox (that says, check all items). I am having hardtime to make use of Selected or itemindex properties of TcxListBox and there is not much information available for the same.

All i am trying to accomplish is this :

If at run time, user checks on the checkbox then all items of a TcxListBox should get selected so that i can take the values of all of them and put them in an array.

Please see the attached image.

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;
      }
    }
}

  By the way, one loop is enough if you use the Checked value instead of hard-coding true/false:
  
  ... var state = UserForms.List_XLS.chkAll.Checked; for (var c = 0; c < UserForms.List_XLS.lstXLS.Items.Count; c++) { UserForms.List_XLS.lstXLS.Selected(c) = state; }

  Hi Ryan,
  
  UserForms.List_XLS.lstXLS.Selected(c) = true;
  
  was the key i was looking for. Because Selected returns true and false, i don't know for some reason, i couldn't think of assigning true and false to it.
  
  It worked, many Thanks for your timely help.
  Regards,
  Vik

    Hi,
    
    Not the Python, but for JScript something like this should work:
    
    for (var i = 0; i < UserForms.<Form>.<List>.Items.Count; i++) if (UserForms.<Form>.<List>.Selected(i)) strValue = strValue + <separator> + UserForms.<Form>.<List>.Items.Items(i);
