LINQ: GroupBy, Sum and EntityCollection in CRM

Just sharing a sample code that could be used for group by and sum operation on EntityCollection.

Suppose below is the output that we want

We can use the below code for that.

// select categoryid, final forecast, final awards from SubCategory Entity
// category id is lookup in SubCategory Entity

EntityCollection result = orgProxy.RetrieveMultiple(new FetchExpression(fetch));

var details = from r in result.Entities.AsEnumerable()
group r by new
groupByCategoryID = ((EntityReference)r.Attributes["categoryId"]).Id.ToString()
into g
select new
sumFinalForecast = g.Sum(x => Convert.ToInt32(x.Attributes["finalforecast"])),
sumFinalAwards = g.Sum(x => Convert.ToInt32(x.Attributes["finalawards"])),
categoryId = g.Key.groupByCategoryID

// update the parent record
foreach(var detail in details)
Entity entityUpdate = new Entity("category");
entityUpdate.Id = new Guid(detail.categoryId);
entityUpdate.Attributes["totalfinalforecast"] = detail.sumFinalForecast;
entityUpdate.Attributes["totalfinalawards"] = detail.sumFinalAwards;

Using WebClient to call external service from CRM Online Sandboxed Plugin (HTTP POST and JSON)

Sharing a sample code that can be used to send JSON data using POST to an external service inside CRM Online Plugin. As plugin runs in sandbox mode we cannot reference Newtonsoft’s JSON.NET library The other option could be to use ILMerge, which isn’t that elegant.

Here, basically we are passing some information related to lead to an external service on Post Create of it.

using Microsoft.Xrm.Sdk;
using System;
using System.IO;
using System.Net;
using System.Runtime.Serialization.Json;
using System.Text;

namespace MyTestPlugin

 public class Lead
 public string Topic { get; set; }
 public string FullName { get; set; }
 public string Email { get; set; }

 public class MyPluginClass : IPlugin
 public void Execute(IServiceProvider serviceProvider)
 // Obtain the execution context from the service provider.
 IPluginExecutionContext context = (IPluginExecutionContext)serviceProvider.GetService(typeof(IPluginExecutionContext));

 // The InputParameters collection contains all the data passed in the message request.
 if (context.InputParameters.Contains("Target") && context.InputParameters["Target"] is Entity)
 // Obtain the target entity from the input parameters.
 Entity entity = (Entity)context.InputParameters["Target"];

 using (WebClient client = new WebClient())
 var myLead = new Lead();
 myLead.Topic = entity.Attributes["subject"].ToString();
 myLead.FullName = entity.Attributes["fullname"].ToString();
 myLead.Email = entity.Attributes["emailaddress1"].ToString();

 DataContractJsonSerializer serializer = new DataContractJsonSerializer(typeof(Lead));
 MemoryStream memoryStream = new MemoryStream();
 serializer.WriteObject(memoryStream, myLead);
 var jsonObject = Encoding.Default.GetString(memoryStream.ToArray());

 var webClient = new WebClient();
 webClient.Headers[HttpRequestHeader.ContentType] = "application/json";
 var code = "key";
 var serviceUrl = "" + code;

 // upload the data using Post mehtod
 string response = webClient.UploadString(serviceUrl, jsonObject);
 catch (Exception ex)
 throw new InvalidPluginExecutionException(ex.Message);

Configure Automatically suggest knowledge articles using Cognitive Services Text Analytics (Preview) in Dynamics 365 (online)

As a first step, we need to set up Text Analytics Service and connect it to our CRM Online. Follow the below post for that

Next, we need to set up Knowledge Search field settings

For this go to Settings – Service Management and click on Knowledge Search field Settings

There click on New to create a new Search Model record.

Below we have specified case as our source entity. Click on Save.

Next, we need to define Keyword fields for our model, click on + to create a new text analytics entity mapping record.

To keep things simple, we have selected entity as Case and Field as Case Title based on which suggestions will be made. Save the record.

Click on Activate to activate the model.

Next, we need to modify the Case form to include knowledge base suggestions

Open the Conversation Tabs, go to Knowledge Base Search and select Text Analytics for Give Knowledge base suggestions as described below and publish the form

Open any of the case record, go to KB Records. Here based on the Case Title, the text analytics picks up the keyword “Delay” and shows/suggests the corresponding KB Articles matching that keyword.

Configure Dynamics 365 and Azure Service Bus Integration (using TwoWay relay, Azure Aware Plugin and listener)

Let us pick up from where we left in the previous post and implement two way relaying through which we can get the response back from the listener.

First let us update the Service Endpoint Registration, change the designation type to TwoWay, it would also ask to enter the SAS Key. Copy it from Azure and paste it.

Update the listener windows application created in the previous post to implement ITwoWayServiceEndpointPlugin

Use the below code to create the custom azure aware plugin.

Get the service endpoint id from the Properties window of the Service End Point registered.

Register the assembly and add the Post Create Synchronous Lead Step to it.

As we are using trace service to log the response, set All for Enable logging to plugin-trace log option from Administration – System Setting – Customization.

Start the listener windows application and to trigger the plugin, create the lead record

We can see the execute method being called from Azure Service bus on create of Lead record.

The message being returned from listener application to the plugin.

The newly created lead record.

The trace message within the plugin –

Plugin Trace log with the response received from the listener –

Using Custom JavaScript field on Entity List to add JavaScript in Portal in Dynamics 365

Suppose we have added an Entity List on Portal to display Contact information to the portal.

Now we want to add some JavaScript to it. For this we can use the Custom JavaScript field in Options tab of Entity List.

$(document).ready(function () {

$("#EntityListControl").on("loaded", function () {

$('#EntityListControl td').filter(function () {
return this.textContent === "SYSTEM"
}).css("color", "red");


We can make use of jQuery for this. The above code selects the TD with text System and highlights it with red font colour.

Hope it helps..
