title: How to select datagrid's specific row using ViewModel for given row number say: make row no 2 selected in datagrid?
body: <p>I am using MVVM light with silverlight 4. I am using EventToCommand to get selected rows from the datagrid. However i am not able to do it in reverse way i.e. from some defined value say 2 in view model how can I ask to place selection to row no 2 in the datagrid on view?'</p>
  
  <p>My scenario I am using it for inserting new data in database. From ViewModel i am able to generate the new row in datagrid by adding one more item in ObservableCollection. Now I want to view to select that defined new row. How could I do that.</p>
  
  <p>My logic is:
  1. since we can have total number of data record we know which one is that last row.
  2. By using the Last row's number I want to create some event that will tell datagrid to select that row.  </p>
  
  <p>I am working on this for few days and not getting any idea how it works using MVVM light.</p>
