How Retreive/RetriveMultiple Message Works in Plugin?

Question

I want to know how exactly or where and all Retreive/RetreiveMultiple Messages triggered in Pluign in Dynamics CRM

Naimish Makwana · Answer

In Dynamics CRM the Retrieve and RetrieveMultiple messages are triggered in various scenarios: Retrieve Message : The Retrieve message is triggered when an entity form is opened or when an entity is being accessed using the Retrieve operation in one of the service endpoints1. For example when you open a record in the CRM a Retrieve message is triggered to fetch the data for that record1. RetrieveMultiple Message : The RetrieveMultiple message is triggered due to various actions in the application and service endpoints for example when populating a grid in the user interface1. This could be when you’re viewing a list of records in a view or when you’re running an Advanced Find query2. In terms of plugins you can register a plugin on these messages. For instance you can create a RetrieveMultiple plugin that gets triggered when a retrieve multiple request is executed on an entity2. This can be useful if you want to manipulate the data that’s being retrieved or apply some custom business logic. However it’s important to note that adding synchronous plugin logic to the Retrieve and RetrieveMultiple message events can result in unresponsive model-driven apps or slow client interactions1. Therefore it’s generally not recommended to register plugins for these messages due to the risks associated with slowing down the requests to return an entity record or records from various entry points1. Remember any adjustments that you make in Retrieve will be applied for RetrieveMultiple 3. Also not all entities support RetrieveMultiple  and the plugin will fire even if there are no results returned from the query2. Thanks
