Answer 1

How about this solution?

<ComboBox Name="myComboBox"  SelectionChanged="status_SelectionChanged" ... />

private void status_SelectionChanged(object sender, SelectionChangedEventArgs e)
{
    var value = (sender as ComboBox).SelectedItem;
}

If you need to get value in other column but in same row, you can make new event for cells of your DataGrid and take needed value something like that

DataGrid.Item[var1,var2]

Where var1 is a row number and var2 column number.

When I have to use Datagrid with complex cells, i save row and column number of each element (ComboBox in your case) in .Tag property, and eject it for determine cell number.
