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;

Hope it helps..

Sample code to call Action using Web API in CRM

Just sharing a sample code to call an Action through Web API.

Suppose below is our Action with one input parameter.

JavaScript code :-

function CallAction() {

// get the id of the record and remove the curly bracket part
// id will be used in Web API url
var Id ='{', '').replace('}', '');

var serverURL = Xrm.Page.context.getClientUrl();

// pass the id as inpurt parameter
var data = {

"recordid": Id

var req = new XMLHttpRequest();

// specify name of the entity, record id and name of the action in the Wen API Url"POST", serverURL + "/api/data/v8.2/sab_costmanagements(" + Id + ")/Microsoft.Dynamics.CRM.sab_Recalculate", true);

req.setRequestHeader("Accept", "application/json");
req.setRequestHeader("Content-Type", "application/json; charset=utf-8");
req.setRequestHeader("OData-MaxVersion", "4.0");
req.setRequestHeader("OData-Version", "4.0");
req.onreadystatechange = function () {
if (this.readyState == 4 /* complete */) {
req.onreadystatechange = null;
if (this.status == 200) {
var data = JSON.parse(this.response);
} else {
var error = JSON.parse(this.response).error;

// send the request with the data for the input parameter

Basically we need to pass name of the Entity Set with id of the record followed by name of the action appended with Microsoft.Dynamics.CRM.

In case of global action, we just need the Microsoft.Dynamics.CRM.<<ActionName>>.

Using ILMerge for Plugin in CRM

If we make use of external assembly in our Plugin (sandboxed) we will get the exception of FileNotFound.

So here we can make use of ILMerge which basically merges the assembly referenced and the plugin into a single assembly.

Install the following NuGet Package.

This adds the following files in our Plugin project.

We need to set Copy Local as true for all our referenced assembly that we want to merge with our plugin.

We need to set Copy Local as false for all other assemblies that we do not want to be merged with plugin.

Just build the project and we are done.

The assembly inside Reflector: –

Caching Issue in The Portal Connector (TPC)

We had products configured from CRM to E Commerce settings in TPC. However, what we observed that any update that we are making to prices in the product is not reflecting to the end user using the Portal.

We cleared the cache, deleted the product form TPC did full synchronization etc. but still we were getting the same price for the products in the Product List.

In Product List

The price for the product (the same was the value in CRM)

However, for the end user in the portal the value was showing up the old value.

Eventually we ended up cloning up i.e. creating a new Product with exact same details and doing full synchronization inside TPC.

This worked.

Hope it helps..
