Combo box list empty (Zero) Count

[Vikas1712]

Hi All, I am unable to retrieve value list from combox. Same below code work perfectly fine in Notepad --> Format--> Font --> Script comboBox list. When I compare Properties of both combox are same.

 var combo = StructuralModelWindow.FindElementByAccessibilityId("StructuralModel");
 var open = combo.FindElementByName("Open");
 combo.SendKeys(Keys.Down);
 open.Click();
  var  listItems = combo.FindElementsByTagName("ListItem");
  Debug.WriteLine($"After: Number of list items found: {listItems.Count}"); // return 0  value

@Vikas1712 My application creates a popup window that owns the ListItems. Perhaps yours is doing the same? Another approach is to wait until .FindElements() returns at least 1 element before proceeding because .FindElements() does not guarantee any elements will be there when it looks at machine speed.
