I need to set a value to a lookup field but I don't know how to do that

this is the code I have

var entity = context.GetEntityFromContext().ToEntity<pwc_contract>();

var aircraftid = aircraftRetrieved.Entities[0].Attributes["pwc_aircraftid"];
var aircraftGuid = new Guid(aircraftid.ToString());
entity.Attributes["pwc_aircraftid"] = new EntityReference("pwc_aircraft", aircraftGuid);
                                
service.Update(entity);

the lookup field is "pwc_aircraftid"

I hope you can help me

thanks

Get Value of Lookup fields

EntityReference entref = (EntityReference)item.Attributes[attributeName];

var LookupId = entref.Id;

var logicalName = entref.LogicalName;

Set Value of Lookup fields

newAccount[attributeName] = new EntityReference(logicalName, LookupId);

If you don't use ID you can not create a Lookup Field. let to write in log then you can see where is breaking.

I don't know exactly what you are doing with "context.GetEntityFromContext" (I get my context a liitle bit different) but I don't think this is a Problem here ;)

are you using earlybindings ?

if you want to set the lookup inside the entity for which the plugin is running and you registered it in "pre"-step, the plugin runs before the record is updated and you don't have to call "Service.Update(entity).

You only need to call the Update-Method manually when you want to update other entities or your plugin is running in Post-Mode.

RE: Set value into lookup field

I have the same code

entity.Attributes["pwc_aircraftid"] = new EntityReference("pwc_aircraft", aircraftGuid);

but the lookup field seems to be null, is that because I need to set the Name with the ID in the entityReference?

RE: Set value into lookup field

Lookup fields in CRM 2011 are EntityReference, this means you need to know the LogicalName of the entity the lookup is pointing and the Id of the record.

as example:

Account acc = new Account(); acc.Attributes["name"] = "Ram"; // this values got inserted acc.Attributes["age"] = "22"; // this values got inserted acc.Attributes["lookupfieldid"] = new EntityReference("contact", contactId); // if lookupfieldid is pointing to contact entity
service.Create(acc); // to create account

if you want to update;

as example:

Entity recordToUpdate = service.Retrieve("contact", contactId, new ColumnSet(true)); recordToUpdate["parentcustomerid"] = new EntityReference("account", accountId); service.Update(recordToUpdate);

first get the record to update, after set the lookup field with an EntityReference and after you save the record.

thanks
