Remarks
The DataSource property specifies the data source that contains tasks. Use the ConstraintTypeFieldName property to specify the name of the field that stores types of constraints applied to the tasks.
The field’s data type should be either ConstraintType or Int32. The ConstraintType enumeration is a set of named integer constants. You can store constraint types as integers in the data source.
