Hello there, fellow power platform customizers/developers! Have you tried to override the default open behavior in subgrid and failed?
What I’ve found in my research:
Documentation by Microsoft says: “You can now create a command definition for an entity with Mscrm.OpenRecordItem as the value of the Id attribute (<CommandDefinition> (RibbonDiffXml)), and define custom action for the command <Actions> (RibbonDiffXml). Customer Engagement will look for this command Id for an entity when you try to open a record from the entity-bound grid, and if present, will execute the custom action instead of opening the entity record (default behavior).”
IMPORTANT NOTE: This feature is supported only for Unified Interface.
Did this. No luck. What now? Google…
