title: SL How to enable edit mode for whole row in GridView?
body: <p>I need to allow users on mouse click in DataGrid to edit whole row? 
  Right now users must double click on cell to enter it in edit mode and I want to make all cells of a selected row to be in edit mode. I need to do this in code.</p>
  
  <p>I was trying to call BeginEdit on Grid's MouseLeftButtonUp but it didn't work.</p>
