Custom Workflow State

Custom Workflow State

• Tarey Wolf

  Elif,

  Thanks a lot. Absolutely it was very helpful. Is there any documentation available on the Toolbox item

  I've used code like

  [ToolboxItem(typeof(EmailStateboxItem))]

  [ToolboxBitmap(typeof(EmailState), "Resources.State.ico")]

  and i'm not quite sure what all the other custom attributes are used for.

  Thanks a lot

  First of all you have to derive from StateActivity not StateMachineWorkflowActivity if you want to do a custom state activity.

  And then you have to go to the code beside (the .cs file not .Designer.cs file i am assuming you are using C#) then write you custom toolbox item for that and add the custom toolbox item as the ToolBoxItem attribute for the custom state activity. In the custom toolbox item class you have to override the CreateComponentsCore method.

  For example:

  [ToolboxItem(typeof(MyToolboxItem))]

  public partial class CustomState: StateActivity

  {

  .....

  }

  ...

  public class MyToolboxItem: ActivityToolboxItem

  {

  override IComponent[] CreateComponentsCore(IDesignerHost host)

  {

  CustomState act1 = new CustomState();

  //over here create and add the eventdriven activities to your custom state activity act1

  return (IComponent[]) new IComponent[] { act };

  }

  }

  Hope this helps

  Thanks

  You can find some nice content - books- at this link

  http://wf.netfx3.com/content/resources.aspx

  Also when you open the Visual Studio 2005 documentation you can see the help document for Windows Workflow Foundation among one of those tabs too. Look for creating custom activities under

  Windows Workflow Foundation

  Windows Worklfow Foundation Programming

  Develiping Workflow Activities

  Creating Custom Activities

  and you will be able to see all the attributes over there.

  Thanks
