title: DataGridView get current selected object
body: <p>I need to get the currently selected object from da databound DataGridView.</p>
  <p>I do not need the object of the current selected cell, but the object on which the whole row is based, in this case a BusinessObject whos properties make the columns of the grid.</p>
  <p>I could go over the DataSource, but that itself is just an object and can be a BindingSource or a IBindingList or something like that - so not easy standartized way to get the wanted object.</p>
  <p>Behind that is the need to just check the businessObject for a property called IsChanged and ask the user to save or discard the changes, before the bindingsource selects the next item. Therefore I must find out the current object inside RowValidating-Event of the DataGridView, since the BindingSource does not offer an event to stop changing before change occurs.<a href="http://social.msdn.microsoft.com/forums/en-US/winformsdatacontrols/thread/0921c331-8593-4827-80ad-4db6b0797f80/" rel="noreferrer">See here for the well known problem</a></p>
