Edit: You bound the ItemsSource of the DataGrid, you cannot add items to the grid itself while that is the case, add the items to the bound collection (which is what i originally suggested)

I would not suggest you do anything like that. In WPF you should bind your controls to the data, that way you can change the source-collection and the grid will get updated automatically, which is less messy than using any method like DataGrid.Items.Add which accepts input of type object.

e.g.
Xaml:

    <DataGrid ItemsSource="{Binding GridData}" Name="DGrid"/>
    <TextBox Name="TB" Width="100"/>
    <Button Content="Add" Click="Button_Click"/>

Code:

    private ObservableCollection<Employee> gridData = new ObservableCollection<Employee>();
    public ObservableCollection<Employee> GridData
    {
        get { return gridData; }
    }

    private void Button_Click(object sender, RoutedEventArgs e)
    {
        GridData.Add(new Employee(TB.Text, "Beatles?"));
    }
