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,

How do i get selected values of TcxListBox.

I have created my own UserForms with controls.
Now i want to get all selected data in my python function.

Please refer my attachment.

  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);
