    PROJECT DESCRIPTION

    In the provided example is demostrated how to use a Telerik OpenAccess ORM domain model within a WPF application. The example uses a MVVM architecture.
    The Model-View-ViewModel (MVVM) is an architectural pattern used in software engineering.

    Key Highlights:
        -  Model - refers to the data access layer representing the real state content;
        -  View - refers to all elements displayed by the GUI;
        -  ViewModel - an abstraction of the View that also serves in data binding between the View and the Model;
        -  Repository pattern -   methods for retrieving and manipulating entities;
        
    Requirements:
        -   Northwind database;

    UPDATE:The most recent version of this project can be found in the Software Development Kit, which you can download here. In case you have questions related to this project, please use the support ticketing system.

    When I try and open the NorthwindApplication.xaml file I get the following errors
    Error 3 The type 'Model.Category' cannot be used as type parameter 'TEntity' in the generic type or method 'ViewModel.Repository<TEntity>'. There is no implicit reference conversion from 'Model.Category' to 'Telerik.OpenAccess.SPI.dataobjects.PersistenceCapable'. C:\Users\THamaluk\Downloads\Telerik\OpenAccess\wpfmvvmusingopenaccess\ViewModel\CategoryViewModel.cs 22 54 ViewModel
     
    the code that causes these errors is

     

     

    public CategoryViewModel()

     

    {

     

    this.repositoryCategory = new Repository<Category>();

     

     

    this.repositoryProduct = new Repository<Product>();

     

     

    this.Load();

     

    }
    with "Category" and "Product" causing the above error. Can you please help me correct these errors ?

    Hello Telerik Admin,

    You could download the Telerik OpenAccess SDK(blog post) that we introduced in Q3. The SDK browser ships rich set of examples including implementation of Silverlight application using MVVM.
    You could find it from your account under the download section.
    Hope that helps.

    I was able to download, build and run this sample, however is there any documentation that explains how it works ?

    Are there any other ORM and WPF MVVM samples ?

    Hi Telerik Admin,

    1.    Currently we do not provide documentation about the examples shipped with the Telerik OpenAccess SDK.
    2.    You could find this help section useful. It demonstrates how to use Telerik OpenAccess ORM with WPF.
    If any other question arise please contact us back.
