        var fieldName = string.Empty;

            // If Contains, Extract value from Target Entity
            if(updateEntity.Contains("new_fieldname"))
            {

                fieldName = updateEntity["new_fieldname"].toString();

Hi Keysersozeey,

Read this article to understand the data context passed to a plug-in. Also make sure to check that you have registered the Pre-Image.

Hi,

You don't need to add any reference, Can you share your plugin registration details?? just want to check as Target is not available in every event, if you have registered your plugin on update

Make sure

1. Your plugin firing.

2. if you have used filtering attribute it means it will only fire on change of that specific field.

Also you should check if it exists or not before trying to get value from it.

Hi Keysersozeey,

You can use this as a template for your plug-in.

using Microsoft.Xrm.Sdk; using System; namespace Namespace { public class Plugin : IPlugin { public void Execute(IServiceProvider serviceProvider) {
ITracingService tracer = (ITracingService)serviceProvider.GetService(typeof(ITracingService)); IPluginExecutionContext context = (IPluginExecutionContext)serviceProvider.GetService(typeof(IPluginExecutionContext)); IOrganizationServiceFactory factory = (IOrganizationServiceFactory)serviceProvider.GetService(typeof(IOrganizationServiceFactory)); IOrganizationService service = factory.CreateOrganizationService(context.UserId); try { //Your code goes here } catch (Exception e) {
tracer.Trace(e.ToString()); throw new InvalidPluginExecutionException(e.Message); } } } }

Hi,

You should pass IServiceProvder as parameter which contains everything -

Try with this -

protected void ExecuteYourPlugin(IServiceProvider serviceProvider) { ITracingService tracingService = (ITracingService)serviceProvider.GetService(typeof(ITracingService)); IPluginExecutionContext context = (IPluginExecutionContext)serviceProvider.GetService(typeof(IPluginExecutionContext)); IOrganizationServiceFactory serviceFactory = (IOrganizationServiceFactory)serviceProvider.GetService(typeof(IOrganizationServiceFactory)); IOrganizationService service = serviceFactory.CreateOrganizationService(context.UserId); // Get Target Entity var updateEntity = (Entity)context.InputParameters["Target"]; // Get PreImage Entity var preEntity = (Entity)context.PreEntityImages["PreImage"]; // Is in Update if (context.MessageName.ToLower() == "update") { var fieldName = string.Empty; // If Contains, Extract value from Target Entity if (updateEntity.Contains("new_fieldname")) { // Cast the fields according their type fieldName = updateEntity["new_fieldname"].ToString(); } // Else extract the value from preImage else if (preEntity.Contains("new_fieldname")) { // Cast the fields according their type fieldName = preEntity["new_fieldname"].ToString(); } } }
