EA_OnPreNewAttribute notifies Add-Ins that a new attribute is about to be created on an element. It enables Add-Ins to permit or deny creation of the new attribute.

This event occurs when a user creates a new attribute on an element by either drag-dropping from the Browser window, using the 'Attributes' tab of the Features window, or using the in-place editor on the diagram. The notification is provided immediately before the attribute is created, so that the Add-In can disable addition of the attribute.


Function EA_OnPreNewAttribute (Repository As EA.Repository, Info As EA.EventProperties) As Boolean

The EA_OnPreNewAttribute function syntax contains these parameters.
