I'm new in the community, I'm strugging with a plugin of a form, where I need to get all the values of that form, in order to achive this I created a preOperation Update Plugin. My plugin works perfectly only if I modify the fields inside that form. However, a normal user (I'm an admin) cannot modify any value of the form. I read that I can use the method
service.Retrieve(string entityName, Guid id, ColumnSet columnSet);
My question is how can I get the Guid id of the current record? Sorry if it is to obvious but I'm new in Dynamics CRM, I appreciate any help you can give me.
