title: Select Tab Page in TabControl without stealing focus
body: <p>Using <code>TabControl.SelectTab("...")</code> shows the tab but it also gives the tab focus.  I would like to show a particular tab, but keep focus where it is.</p>
  
  <p>I have data rows in a grid.  Based on properties of the selected row, I show a different tab page to have a different UI layout.  But when using arrow keys to scroll through rows, the focus switches to the selected tab -- which I don't want to happen.</p>
  
  <p>Thanks.</p>
