title: Selecting a row in a DataGridView and having the arrow on the row header follow
body: <p>This is in C#. If I select a row in a DataGridView with DataGridViewRow.Selected = true, the row selects just fine, but the arrow in the "column header" (the grey very leftmost column) doesn't follow. How do I set that?</p>
  
  <p>Another question: If I set a column format to "centered" in the designer, the column header is still left aligned. How do I set the column header to be centered too?</p>
  
  <p>Thanks,
  Brian</p>
