Auto Filling Event Registration Form In Dynamics 365 Portal

To find the contact entity and lead matching the email address, set the reference to Event Registration Form in Dynamics 365 portal.

I have got a requirement from the client, which says “Event Registration Form” has a “Related Contact and Lead”, which should be automatically filled, if it has an email address matching “Event Registration Form – email address”. All these should happen when the user registers for an event from “Dynamics 365 – Customer Self Service Portal”.

Steps to achieve this are given below.

Step 1

Create a plugin to find out the email address, which has any matching contact or lead and set the reference to Related Contact and Lead.

Go to Visual Studio and create a Class Library project, as shown below.


Step 2

Now, use the code given below to create plugin class like “EmailLookupForContactNLead.cs”, as shown in the step 1.

  2. using System.Collections.Generic;  
  3. using System.Linq;  
  4. using System.Text;  
  5. using System.Threading.Tasks;  
  6. using Microsoft.Xrm.Sdk;  
  7. using System.ServiceModel.Description;  
  8. using Microsoft.Xrm.Sdk.Query;  
  9. using System.Runtime.Serialization;  
  10.   
  11. namespace Dynamics_365_Portal.EmailLookupForContactsNLead  
  12. {  
  13.     public class EmailLookup   IPlugin
