Retrieve attributes values from entity calling plugin

  If the 'Target' property contains an Entity object, you can use the above code to retrieve the attributes. You don't need to call the retrieve method.

  If the plugin is called by an update message, you might also want to look into using Pre and Post Images.

  Kind regards

  Hi

  If you want to retrieve values from same entity then you can directly use them from plugin Context

   

  If you want to access any other value you can user retrieve or retrieve multiple method of Organization service object from same plugin

   

  Following is the sample example of plugins

   public void Execute(IServiceProvider serviceProvider)
          {
              Microsoft.Xrm.Sdk.IPluginExecutionContext context = (Microsoft.Xrm.Sdk.IPluginExecutionContext)serviceProvider.GetService(typeof(Microsoft.Xrm.Sdk.IPluginExecutionContext));
              Microsoft.Xrm.Sdk.IOrganizationServiceFactory serviceFactory = (Microsoft.Xrm.Sdk.IOrganizationServiceFactory)serviceProvider.GetService(typeof(Microsoft.Xrm.Sdk.IOrganizationServiceFactory));
  
              try
              {
                  // The InputParameters collection contains all the data passed in the message request.
                  if (context.InputParameters.Contains("Target") && context.InputParameters["Target"] is Entity)
                  {
                      // Accress the Attributes from same entity
                      // Accress the Attributes from same entity
                      Entity entity = context.InputParameters["Target"] as Entity;
                      if (entity != null)
                      {
  
                          if (!entity.Contains("yourAttributeName"))
                              entity.Attributes.Add("yourAttributeName", "yourValue");
                          else
                              entity["yourAttributeName"] = "your Value";
                      }
                  }
  
  
                  // Accress the Attributes from other entity
                  // Accress the Attributes from other entity
                  IOrganizationService service = serviceFactory.CreateOrganizationService(context.UserId);
                  var manyEntityies = service.RetrieveMultiple(new QueryExpression("yourOtherEntityName") { });
  
              }
              catch (InvalidPluginExecutionException ex)
              {
                  throw ex;
              }
  
          }

  Hi,

  thank you for your reply.

  We usually use the above code for a Create message?

  Yes you can, you don't have to use retrieve, one exception is attribute collection will only contain the attributes which are modified by the user. When the user updating a record, you can register a pre-image with the update plugin registration process, and you don't need to call retieve and you can get attribute value from pre-entity.

  please refer the following sample code

   var context = (Microsoft.Xrm.Sdk.IPluginExecutionContext)
                              serviceProvider.GetService(typeof(Microsoft.Xrm.Sdk.IPluginExecutionContext));
  
              if (context.InputParameters.Contains("Target") &&
                                         context.InputParameters["Target"] is Entity)
              {
  
                  var targetEntity = (Entity)context.InputParameters["Target"];
  
                  if (targetEntity.LogicalName != "account")
                      return;
                  //Retrieve data.
                  var trackingOptionObj = targetEntity.GetAttributeValue<OptionSetValue>("new_trackingoption");
                  var accountId = targetEntity.GetAttributeValue<Guid>("accountid");
                  var newCustomerStatus = targetEntity.GetAttributeValue<OptionSetValue>("new_customerstatus").Value;
                  var current_syn_customerid = targetEntity.GetAttributeValue<string>("new_customerid");
                  var current_syn_debtorclassid = targetEntity.GetAttributeValue<EntityReference>("new_customerclass").Id.ToString();
  
                  //Add attribute
                  Guid contactId = Guid.Empty; //sepcify value
                  targetEntity.Attributes.Add("primarycontactid",
                                                                    new EntityReference("contact", contactId));
  
              }
  

  
  to read pre or post image, please refer the following code, reading attribute value is same as above.

  var preEntity = (Entity)context.PreEntityImages[preimagename];
  var postEntity = (Entity)context.PostEntityImages[postimagename];

  Hi Thomas,

  This was very helpful, thank you!

  I know it's a change of subject but since you mentioned it in your code and I'm looking for it, how can we read the text value of the optionset?

  Hi,

  You can use FormattedValues

  
  

  myEntity.FormattedValues["paymenttermscode"].ToString()
  

  <br/>
  

  <br/>
  

         Console.WriteLine("Value: {0}", ((OptionSetValue)account.Attributes["paymenttermscode"]).Value);
                  Console.WriteLine("Value: {0}", account.GetAttributeValue<OptionSetValue>("paymenttermscode").Value);
                  Console.WriteLine("Text: {0}", account.FormattedValues["paymenttermscode"].ToString());

  Hi Thomas,

  FormattedValues is not working, it's throwing the exception "The given key was not present in the dictionary".

  Any idea what could be the reason?
