title: Row Count for WPF DataGrid?
body: <p>How to count or return the last index of a <code>DataGrid</code> row? Apparently there's isn't a <code>DataGrid.Count()</code> property. I searched everywhere and I can't find an answer.</p>
  <p>I could create a variable and use <code>i++</code> as a counter for <code>Row</code> count, but doesn't a <code>DataGrid</code> has a built-in solution?</p>
