TestComplete UserForms - TcxListBox issue

Hi Abhi,

JavaScript (not to be confused with JScript) does not support direct assignment to parameterized properties.

UserForms.UsrForm.cxListAllFunctions.Selected(i) = true;

You need to use the $set method instead:

UserForms.UsrForm.cxListAllFunctions.$set("Selected", i, true);

JavaScript Specifics - Indexed Properties

By the way, you can make this code a bit simpler by using variables:

function UsrForm_cxCheckBoxAllFunctions_OnChange(Sender)
{
  var form = UserForms.UsrForm;
  var listBox = form.cxListAllFunctions;
  var state = form.cxCheckBoxAllFunctions.Checked;

  Log.Message("List Length is: " + listBox.Items.Count);
  for (var i = 0; i < listBox.Items.Count; i++)
  {
    listBox.$set("Selected", i, state);
  }
}
