I am developing an Azure DevOps extension to validate work item links when they are added in a work item form. I am working with on-premises Azure DevOps and using an XML process model.

The Problem:

1. When I add an existing work item as a link, all events like:

   onFieldChanged

   onSaved …are triggered, and I can validate the link without any issues.

2. However, when I use the “New Item” option to create a new work item and attach it as a link:

   Image reference

   • The new work item is created automatically.
   • The link is added to the parent work item.
   • No events (onFieldChanged, onSaved, etc.) are triggered for this operation.

Key Questions:

1. Is there any way to disable the “New Item” option for creating and attaching links?
2. How can I validate links added via the “New Item” option since events are not triggered?

Environment:

• Azure DevOps Server (on-premises)
• XML process model
• Custom extension using Azure DevOps Extension SDK

I need a way to either:

Intercept the automatic linking behavior triggered by “New Item”.

Or, validate the link after it is added to the parent work item.

Any help, suggestions, or workarounds are appreciated!
