I can use SelectedItem to have the specific node/row selected but the keyboard focus always defaults to first cell in TreeGridView.
Is there a way to focus on specific cell on TreeGridView init?
I need this for a custom GetLayer dialog. I plan to add more functionality to it. This is the screencap of what happens when I run the script:
I would like to have the keyboard focus on the SelectedItem row. Any ideas?
