Using Relationship and RelationshipQueryCollection class to retrieve n to n relationship details in CRM.

Suppose we need to query a n:n relationship and get details of both the entity records involved.

For this we can make use of Relationship and RelationshipQueryCollection class,

Suppose I have an entity named A and it has n to n relationship with B Entity.

This I how we can get the details all the A records associated with a particular entity B record.

i.e. Name of all the A records associated with a particular B entity record along with the name of the B entity record.

</pre>
private void GetManytoManyRelationShipDetails(IOrganizationService _service, Guid entityBGuid)
 {
 // get offences records' name
 QueryExpression query = new QueryExpression("EntityA");
 ColumnSet cols = new ColumnSet();
 cols.AddColumn("EntityANameToBeRetreived");
 query.ColumnSet = cols;

// Relationship Name
 Relationship relationship = new Relationship("EntityA_EntityBRelationshipName");
 RelationshipQueryCollection relationshipColl = new RelationshipQueryCollection();
 relationshipColl.Add(relationship, query);

// get the legal issue record's name
 RetrieveRequest request = new RetrieveRequest();
 request.RelatedEntitiesQuery = relationshipColl;
 request.Target = new EntityReference("EntityB", entityBGuid);
 request.ColumnSet = new ColumnSet("EntityBNameToBeRetreived");
 RetrieveResponse response = (RetrieveResponse)_service.Execute(request);

string entityAName = string.Empty;

foreach (Entity entity in response.Entity.RelatedEntities[relationship].Entities)
 {
 entityAName += entity.Attributes["EntityAName"].ToString();
 }
 }

Hope it helps.

Fixed – Grid can not be used in this (‘quirks’) model in jqGrid

We got the above error in an HTML Web Resource which was using jqGrid. The page was working fine in IE 10 browser only in IE 8 we got that error.

The solution was to use the following meta tag inside the HEAD tag of the html page.

More details on this meta tag

Fixed – Expected identifier, string or number error in HTML Web Resource in IE.

We recently developed an html web resource which was using jqGrid. The web resource was working properly on machines having IE 10 browser, but got the above error in case of IE 8.

As it turned out extra “,” i.e. trailing comma was the reason for the error.

Removing it fixed the issue. IE 10 was more forgiving.

Hope it helps.

Sample Code: OData Synchronous Call in CRM 2011

Just sharing the sample code to make synchronous OData call in CRM 2011.


var oDataRequestUrl = http://server/orgname/xrmservices/2011/OrganizationData.svc/ContactSet?$select=FullName

var result = syncODataCall(oDataRequestUrl);

// function to make synchronous oData call
 function syncODataCall(odataSelect) {
 var request = new XMLHttpRequest();
 request.open("GET", odataSelect, false);
 request.setRequestHeader("Accept", "application/json");
 request.setRequestHeader("Content-Type", "application/json; charset=utf-8");
 request.send();
 var objJQuery = jQuery.parseJSON(request.responseText);
 return objJQuery.d
 }

Check for following methods to parse the result returned

ProcessReturnedEntities(data.d.results)
ProcessReturnedEntity(data.d)

Retrieve OptionSet Label using SDK.Metadata.RertrieveAttribute method in JavaScript (CRM 2011)

Hi,

Recently we were working on an HTML Web Resource which was using oData to fetch information regarding a particular entity which had multiple optionset fields in it.

As we know using oData we can get the value of the optionset field but not the label. While searching for the best possible way to get the label in Jscript came to know about the sdk.metadata.js sample code in SDK (sdk\samplecode\js\soapforjscript\soapforjscript\scripts)

It has RetrieveAttribute method in it which can be used to get the attribute metadata

We had an optionset attribute named Language in it, this is how we fetched all the label and the value for that field


var languageArray = [];

// this.RetrieveAttribute = function (EntityLogicalName, AttributeLogicalName, MetadataId, RetrieveAsIfPublished, successCallBack, errorCallBack, passThroughObject
 SDK.Metadata.RetrieveAttribute("new_lawyer", "new_primary_language", null, true, function (result) {

for (var i = 0; i < result.OptionSet.Options.length; i++) {
 languageArray[result.OptionSet.Options[i].Value] = result.OptionSet.Options[i].Label.LocalizedLabels[0].Label;
 }
 },
 function (error) {
 alert("error");
 }
 );

Hope it helps !
