How do I pass data between activities in Windows Workflow?

Question

I'm not completely sure I understand the workflow way of doing things, but if it's a pipeline n filter style model I should be able to pass data (even strings) from one activity to another.

Does anyone know how to do this? Bonus points for a video!

I hope this is possible. If WF were the same as my idea of it then it would be extremely useful.

Answer 1

Method 1 (Design- and run-time): Activity databinding

You can bind the dependency properties of an activity to the properties of another activity. See

• Activity Binding in Windows Workflow Foundation.
• Enabling Activity Data Binding

Method 2 (Run-time): Find an activity from the activity tree

See

• Paragraph "Workflow Development" of the article ActivityExecutionContext in Workflows.
• Binding to Activity Dependency Property in Code Activity
