    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);
