A UI (control) screen element in Winforms and WPF does not allow access by other threads or multiple threads.

The UI element can only be accessed by the thread that was created on it.

What you can do is to use delegates ...

Invoke(new Action(() =>
{
     if (dataGridView1.CurrentCell.RowIndex < dataGridView1.RowCount )
     {
          dataGridView1.Rows[dataGridView1.CurrentCell.RowIndex].Selected = false;
          dataGridView1.Rows[dataGridView1.CurrentCell.RowIndex + 1].Selected = true;
     }
}));
