Rows.Count is null for WPF's (custom?) DataGrid

The WPF application I'm automating has DataGrid control. Almost all the times listView.Rows returns 0, despite of there are several rows. Number of Columns is correct. I tried to do the same using UIA, but the result was the same. So it's not a white problem. All the UI Spies show correct Rows/Columns numbers (!). Looks like for some reasons I get the state of the grid when it is just loaded, when rows count is 0. Also interesting, that 1 time both White and UIA were able to detect correct number of rows / columns after I just reopen the solution. But all next times after that this workaround has not helped..

Have anyone ever faced with such a problem in White / UIA ?


Window windowMain = UiaHelper.WaitObject(SprinterHelper.GetSprinterWindow);
ListView listTests = windowMain.Get<ListView>(ControlsHelper.Controls[C.RunMode_TestsListView]);
ListViewHeader header = listTests.Header;
ListViewColumn columnName = header.Column("Name");
int indexOfNameColumn = columnName.Index;
// Rows.Count is always == 0... But Spies show correct number.. ??
List<string> testNames = listTests.Rows.Select(r => r.Cells[indexOfNameColumn].Text).ToList();

Sorry, my fault, there where 2 controls with the same properties, one visible, and other invisible. I have written an extension method which lacks in White to solve this problem:

public static T[] GetMultiple<T>(this UIItemContainer container, SearchCriteria criteria, VisibilityScope visibility) where T : UIItem
	IUIItem[] allItems = container.GetMultiple(criteria);
	switch (visibility)
		case VisibilityScope.All:
			return allItems.Cast<T>().ToArray();
		case VisibilityScope.Visible:
		case VisibilityScope.NotVisible:
			return allItems.Where(i => i.Visible == (visibility == VisibilityScope.Visible)).Cast<T>().ToArray();
	return null;
