title: Datagridview SelectionMode Alternative
body: <p>I am trying to modify the way in which selections are made for my datagridview so that it selects in a similar way to text selection.</p>
  
  <p>Currently when a series of cells are selected in multiple rows only the cells selected are highlighted.

  <p>However what i'd like it to do is when the second row is selected it also selects all cells to the right of the first selected cell, and all cells left of the second selected cell, exactly the same as highlighting text in a browser.</p>

  <p>Is there some property or mode that I can set to make the datagridview selection behave like this?</p>
