Hi Rajesh
I believe you want to write a Plugin on Associate Message, In Plugins, the Associate & Disassociate messages behave little different than other messages. When you register a plugin on Associate message, you have to leave “Primary and Secondary” entities as ‘none’. Since we don’t provide entity names, the registered Plug-in step triggers on all “Associate” operations, so we have to check few conditions to let the “Association” trigger happen only between intended entities.
You can use the below code template for Associate or Disassociate plugins
EntityReference targetEntity = null;
string relationshipName = string.Empty;
EntityReferenceCollection relatedEntities = null;
EntityReference relatedEntity = null;
if (context.MessageName == “Associate”) {
// Get the “Relationship” Key from context
if (context.InputParameters.Contains(“Relationship”)) {
relationshipName = context.InputParameters[“Relationship”].ToString();
}
// Check the “Relationship Name” with your intended one
if (relationshipName != “{YOUR RELATION NAME}”) {
return;
}
// Get Entity 1 reference from “Target” Key from context
if (context.InputParameters.Contains(“Target”) && context.InputParameters[“Target”] is EntityReference) {
targetEntity = (EntityReference)context.InputParameters[“Target”];
}
// Get Entity 2 reference from ” RelatedEntities” Key from context
if (context.InputParameters.Contains(“RelatedEntities”) && context.InputParameters[“RelatedEntities”] is EntityReferenceCollection) {
relatedEntities = context.InputParameters[“RelatedEntities”] as EntityReferenceCollection;
relatedEntity = relatedEntities[0];
}
}
