TestComplete UserForms - TcxListBox issue

Hello,

 

I have a listBox and need to select all the rows in the list after a checkbox is checked.

This is the piece of code that I'm using. I'm running into an issue  at the line marked in bold. I've attached the snapshot of error as well. any help would be appreciated!

 

 

 

function UsrForm_cxCheckBoxAllFunctions_OnChange(Sender)
{

  
  if(UserForms.UsrForm.cxCheckBoxAllFunctions.Checked){
      Log.Message("List Length is: " +UserForms.UsrForm.cxListAllFunctions.Items.Count);
      for(var i = 0; i< UserForms.UsrForm.cxListAllFunctions.Items.Count; i++){
          Log.Message("UserForms.UsrForm.cxListAllFunctions.Selected("+i+") = " + UserForms.UsrForm.cxListAllFunctions.Selected(i));
          UserForms.UsrForm.cxListAllFunctions.Selected(i) = true;
      
      }
  }else{
      for(var i = 0; i< UserForms.UsrForm.cxListAllFunctions.Items.Count; i++){
        
      UserForms.UsrForm.cxListAllFunctions.Selected(i) == false;
      
    }
  } 
  
  

}

 

 

 

 

Thank you

Abhi

    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 https://support.smartbear.com/testcomplete/docs/reference/language/javascript/set-method.html method instead:

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

    https://support.smartbear.com/testcomplete/docs/scripting/specifics/javascript.html#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);
  }
}

    What output do you get from that Log.Message right above where your error occurs?
