Hello Workflow

Workflows are a way to execute a business process. Each step in that process is implemented by an Activity. We will create a very simple workflow that will be the equivalent to this code:

Interview Questions

Question No. 1: "Tell me about yourself." This is usually the opening Question in an interview and it's the perfect moment for you to toot your own horn -- not to tell your life history. Your answers should be a quick rundown of your qualifications and experience. Talk about your education, work history, recent career experience and future goals.

Building a Composite Activity Designer part(4 - 4)

Part 4  Adding a TextBox to the Workflow Designer

We will add a TextBox control to the hosted Workflow designer that will serve as a XAML code viewer. This will allow us to see the XAML source code as the workflow is edited.

Building a Composite Activity Designer part(3 - 4)

Part 3  Registering the Activities Designers

1. Open Microsoft Visual Studio 2010 from Start | All Programs | Microsoft Visual Studio 2010 | Microsoft Visual Studio 2010.
   

Building a Composite Activity Designer part(2 - 4)

We will learn how to create a composite activity designer. We will use the metadata stored to override the designer of an activity from the workflow activity library. Also, We will add a text box in the hosted workflow designer to display the XAML source code while creating a workflow.

Default designer vs. Composite designer

Building a Composite Activity Designer part(1 - 4)

We will learn how to create a composite activity designer. We will use the metadata stored to override the designer of an activity from the workflow activity library. Also, We will add a text box in the hosted workflow designer to display the XAML source code while creating a workflow.

Default designer vs. Composite designer

Adding Controls to an Activity Designer

We will learn how to add a control (E.g. a text box) to customize the Activity Designer and then bind the control to one of the properties of the activity.

Creating a Basic Activity Designer

We will create the basic styled Activity Designer and register it to use it for the Prompt activity.

Create the Property Inspector In WPF

From last post we will create the Property Inspector window and include it in the WPF grid. To do this, in Solution Explorer right-click the MainWindow.xaml files, choose View Code. Modify the code by following these steps:

Creating the Toolbox and the Property Inspector Windows In WPF

We will create the Toolbox and Property Inspector windows, and add them to the Workflow Designer.

1. From last post create the Toolbox and include it in the WPF grid.  To do this, in Solution Explorer right-click the MainWindow.xaml file and choose View Code. Modify the code by following these steps:

Hosting the Workflow Designer

We will configure the WPF Grid that will contain the Workflow Designer. Then, We will create the WorkflowDesigner instance programmatically, and add a Sequence activity with designer support to it. As a consequence, you will be able to host the Workflow Designer in the WPF application.

Creating a new WPF

Creating a new Windows Presentation Foundation Application

you will create an empty WPF application using the WPF Application Visual Studio template, and add to the solution the FirstApp project .

1. Open Microsoft Visual Studio 2010 from Start | All Programs | Microsoft Visual Studio 2010 | Microsoft Visual Studio 2010.
