The last argument to the AddTrigger method is the change type.

The safest change type to specify is the one returned by the Element.GetChangeTypeAny method.

Here are some discussions mentioning the AddTrigger method on The Building Coder:

• Structural Dynamic Model Update Sample
• Access Deleted Element
• Lock the Model, e.g. Prevent Deletion
• DocumentChanged versus Dynamic Model Updater
• How to Trigger a Dynamic Model Updater by Specific Element Ids
