column dragging error

I found a bug in SfTreeGrid when dragging columns. Here's the steps.

  1. Create new SfTreeGrid
  2. Have columns defined in XAML (dont use generated columns)
  3. Enable dragging of columns.
  4. Then bring up the application with no data. So, ItemsSource is still null.
  5. Try dragging one of the columns. I get a null reference error.

To work around this problem I just initialize my ItemsSource to an empty list.
