    <p>I am currently working on a project where we are converting our old DataSet, Stored Procedure WinForm application to use Entity Framework so new websites can access the same object model and repositories.</p> <p>Anyway, I am trying to implement Dependency Injection into the Forms so that we can use mocked Repositories for unit testing. I am using Ninject for the the simple reason I have used it before in MVC websites, however trying to implement this in the WinForm application is proving to be problematic to say the least, hampered even more by the lack of information on DI in WinForms on the web.</p> <p>So far I have created the Ninject Factory and repositories, but I haven't had much luck injecting the repositories into forms.</p> <p>Therefore can anyone help me or make any suggestions?</p> <p>Below I have parts of my code that might help:</p> <p>Ninject Factory:</p> <pre><code>public class NinjectFactory : NinjectModule { private IKernel _ninjectKernel; public NinjectFactory() { _ninjectKernel = new StandardKernel(); } public override void Load() { _ninjectKernel.Bind(typeof(IRepository&lt;&gt;)).To(typeof(GenericRepository&lt;&gt;)); _ninjectKernel.Bind(typeof(IProductionRepository)).To(typeof(ProductionRepository)); } } </code></pre> <p>Form with repositories:</p> <pre><code>Public Class TaskForm Inherits BaseBusinessDialogForm Private _repository As TaskRepository Private _task As Production.Task = Nothing Public Sub New(ByVal task As Production.Task) InitializeComponent() _repository = New TaskRepository(ConnectString) If task.TaskID = 0 Then _task = task Else _task = _repository.GetByID(task.TaskID) End If MyBase.BusinessObject = _task Me.TaskBindingSource.DataSource = MyBase.BusinessObject End Sub </code></pre> <p>Class that launches the MDI form which holds the above form:</p> <pre><code>Dim kernel As IKernel = New StandardKernel(New NinjectFactory()) ''Dim kernel As IKernel = New StandardKernel(New NinjectFactoryTest()) mfrmMDI = kernel.Get(Of Forms.MDI)() Application.DoEvents() mfrmMDI.ShowDialog() </code></pre> <p>I understand that my question is a bit vague, but I'm not sure where the problem lies or what I need to complete.</p> <p>Thanks very much</p>

    1. COyou have a mix of VB and C#, would it be ok to have answers purely on C#?

    2. COSorry for the mix of languages, it's straight from the project code. The old stuff is in VB and the newer in C#, annoying to say the least!

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
