Step 6. Displaying a Users Window

When you create a new MM .NET WPF application, a UsersWindow is automatically added to the project for you. This is an application-level window derived from mmBusinessWindow that you can modify to your hearts content! To get its basic functionality working, follow these steps:

1. Open the UsersWindow.xaml.cs/vb in Visual Studio and add a reference to your business object project's namespace

2. Next, uncomment the following lines of code:

   In C#:

   //protected User User;
   //protected Role Role;

   //this.User = (User)this.RegisterPrimaryBizObj(new User());
   //this.Role = (Role)this.RegisterBizObj(new Role());
   //this.User.RegisterChildBizObj(this.Role);

   And in VB .NET:

   'Protected User As User
   'Protected Role As Role

   'Me.User = CType(Me.RegisterPrimaryBizObj(New User()), User)
   'Me.Role = CType(Me.RegisterBizObj(New Role()), Role)
   'Me.User.RegisterChildBizObj(Me.Role)

3. Next, uncomment the code in the following methods:
   • Window_Loaded
     
   • mvrRoles_RefreshLists
     
   • mvrRoles_AddItem
     
   • mvrRoles_DeleteItem
     
   • mvrRoles_Delete

4. Open your WPF project in Expression Blend

5. In the Project panel, double-click UserWindow.xaml to open it in the design surface.

6. In the Objects and Timeline panel, select the Window element:

   

7. Go to the Properties panel, and under the Common Properties section, click the DataContext property's New button:

   

8. This launches the Select Object dialog. Expand the node containing the namespace of your business objects, select the UserEntity class and click OK:

   

9. Save changes to the window
