You can use custom parts to capture custom transactions, process custom transactions, and access content from The Raiser's Edge not available through standard Blackbaud NetCommunity parts. You cannot use custom parts to modify existing Blackbaud NetCommunity features.
Blackbaud Support does not provide assistance or samples for the creation of Custom Parts. If you would like to get started creating your own Custom Parts, enable the Custom Parts gallery and consult Blackbaud Developer Network for code samples and documentation.
Blackbaud can develop a custom part to fit your needs as a billable service. Contact your account manager for more information.
