Converting UI from Windows Forms to WPF databinding - wpf

Question

I currently have an application with a user interface in Windows Forms. The code behind this user interface communicates with a service.
For example, I have the following code:
public partial class MainWindow : Window
{
private KeyLessAccessLogic ServiceLogic;
public MainWindow()
{
InitializeComponent();
ServiceLogic = new KeyLessAccessLogic();
//LoadValues();
}
public KeyLessAccessLogic MyServiceLogic
{
get { return ServiceLogic; }
set
{
ServiceLogic = value;
// RaisePropertyChanged("MyServiceLogic");
}
}
private void BindDataSource()
{
cmb_user_name.DataSource = null;
cmb_user_name.Sorted = false;
cmb_user_name.DataSource = ServiceLogic.Users;
cmb_user_name.DisplayMember = "name";
}
And my XAML:
<ComboBox Height="23" HorizontalAlignment="Left" Margin="6,71,0,0"
Name="cmb_user_update" VerticalAlignment="Top" Width="120"
ItemsSource="{Binding Path=MyServiceLogic.Users}" DisplayMemberPath="name" />
Now I recreated the UI in WPF, and I'm a bit lost on the new format. I do believe that example I gave here is one of the examples of the difference between WPF and Windows Forms.
How can I let my application know what the datasource should be of the Dropdown-box cmb_user_name? ServiceLogic is the central block of my service, accessing for example the database.
As a second thing, I have a listbox to show me some devices. I tried to approach the datasource differently to show what else I have tried:
<ListBox Height="100" HorizontalAlignment="Left" Margin="6,44,0,0"
Name="listBox_detected" VerticalAlignment="Top" Width="120"
ItemsSource="{Binding Path=ServiceLogic.TheDevicesList}" DisplayMemberPath="name" />

Answer 1

Use XAML for that:
<ComboBox ItemsSource="{Binding MyServiceLogic.Users}"
SelectedItem="{Binding User}"
DisplayMemberPath="name" />
Create a property ServiceLogic in your ViewModel to hold a ServiceLogic object:
private ServiceLogic myServiceLogic;
public ServiceLogic MyServiceLogic
{
get { return myServiceLogic; }
set
{
myServiceLogic = value;
RaisePropertyChanged("MyServiceLogic");
}
}
I assume Users is ObservableCollection. Or you can create a property which holds Users collection directly.
