wpf datagrid selection changed

Question

Hello,

I used to have the following code using a listview:

private void ListViewSelectionChanged(object sender, SelectionChangedEventArgs e)
        {
            foreach (Exam exam in e.RemovedItems)
            {
                ViewModel.SelectedExams.Remove(exam);
            }
            foreach (Exam exam in e.AddedItems)
            {
                ViewModel.SelectedExams.Add(exam);
            }
        }

Now I changed to a datagrid but I'm getting an error message that says: Error 1 'System.EventArgs' does not contain a definition for 'RemovedItems' and no extension method 'RemovedItems' accepting a first argument of type 'System.EventArgs' could be found (are you missing a using directive or an assembly reference?)

private void DataGridSelectionChanged(object sender, EventArgs e)
    {
        foreach (Exam exam in  e.RemovedItems)
        {
            ViewModel.SelectedExams.Remove(exam);
        }
        foreach (Exam exam in e.AddedItems)
        {
            ViewModel.SelectedExams.Add(exam);
        }
    }

Can anyone out there help me by telling me how I can capture the selected rows in a datagrid in the same way as I used to capture them in a listview.
