In Workflow Studio, we use binding to pass data from one activity to another. Binding can be achieved in two ways: one way is to use the Binding Mapper, and the other is by writing custom C# code in the activities.
Bindings allow you to drag and drop properties from one activity to another using a built-in property mapper or binding mapper. Bindings are bi-directional.
In order to demonstrate how binding works I will create a Workflow and will put one Lookup control and one Form on it. My lookup control will display the list of people in EmpowerID and based on the selected record from the lookup control I will pass that user information on to my Form and my Form will display the selected user information.
