title: WPF binding selectedvalue datagrid to combobox
body: <p>I have a datagrid with databinding to a class with several properties. I would need to bind the selected row values to several combobox or textbox when I can alter the values (2 way binding so).
  Imagine that the datagrid have list of Person with properties like Age and Name associated with 2 combobox where I can choose the values.</p>
  
  <p>How can I make this binding of the selected value properties to the comboboxs?</p>
  
  <p>Thanks in advance!</p>
  
  <p>edit: I would prefer to this in the xaml if possible</p>
