WorkflowDesignerLoader.Initialize Method

  • Reference

Definition

Namespace:
System.Workflow.ComponentModel.Design
Assembly:
System.Workflow.ComponentModel.dll

Initializes the WorkflowDesignerLoader with any services required by the designer loader host.

protected:
 override void Initialize();
protected override void Initialize ();
override this.Initialize : unit -> unit
Protected Overrides Sub Initialize ()

Examples

The following example shows how to override the Initialize method in a derived class to add the services needed for the designer. The services can vary based on the level of service support required by your application.

protected override void Initialize()
{
    base.Initialize();

    IDesignerLoaderHost host = this.LoaderHost;
    if (host != null)
    {
        host.RemoveService(typeof(IIdentifierCreationService));
        host.AddService(typeof(IIdentifierCreationService), new IdentifierCreationService(host));
        host.AddService(typeof(IMenuCommandService), new WorkflowMenuCommandService(host));
        host.AddService(typeof(IToolboxService), new Toolbox(host));
        TypeProvider typeProvider = new TypeProvider(host);
        typeProvider.AddAssemblyReference(typeof(string).Assembly.Location);
        host.AddService(typeof(ITypeProvider), typeProvider, true);
        host.AddService(typeof(IEventBindingService), new EventBindingService());
    }
}

Protected Overrides Sub Initialize()
    MyBase.Initialize()

    Dim host As IDesignerLoaderHost = Me.LoaderHost
    If host IsNot Nothing Then
        host.RemoveService(GetType(IIdentifierCreationService))
        host.AddService(GetType(IIdentifierCreationService), New IdentifierCreationService(host))
        host.AddService(GetType(IMenuCommandService), New WorkflowMenuCommandService(host))
        host.AddService(GetType(IToolboxService), New Toolbox(host))
        Dim typeProvider As New TypeProvider(host)
        typeProvider.AddAssemblyReference(GetType(String).Assembly.Location)
        host.AddService(GetType(ITypeProvider), typeProvider, True)
        host.AddService(GetType(IEventBindingService), New EventBindingService())
    End If
End Sub
