Sample code to retrieve more than 5000 records using FetchXML in CRM


Sharing a sample code to retrieve more than 5000 records using the Fetch XML.

Version 1 :

private List<Entity> GetTotalRecordsfromFetch(string fetchXML, IOrganizationService orgService)
List<Entity> lstEntity = new List<Entity>();

int fetchCount = 5000;
int pageNumber = 1;
string pagingCookie = null;

while (true)
// Build fetchXml string with the placeholders.
string xml = this.CreateXml(fetchXML, pagingCookie, pageNumber, fetchCount);
RetrieveMultipleRequest fetchRequest = new RetrieveMultipleRequest
Query = new FetchExpression(xml)

var returnCollections = ((RetrieveMultipleResponse)orgService.Execute(fetchRequest)).EntityCollection;

if (returnCollections.Entities.Count >= 1)

if (returnCollections.MoreRecords)

results.pagingCookie = returnCollections.PagingCookie;
// If no more records in the result nodes, exit the loop.

return lstEntity;

public string CreateXml(string xml, string cookie, int page, int count)
StringReader stringReader = new StringReader(xml);
XmlTextReader reader = new XmlTextReader(stringReader);

XmlDocument doc = new XmlDocument();

XmlAttributeCollection attrs = doc.DocumentElement.Attributes;

if (cookie != null)
XmlAttribute pagingAttr = doc.CreateAttribute("paging-cookie");
pagingAttr.Value = cookie;

XmlAttribute pageAttr = doc.CreateAttribute("page");
pageAttr.Value = System.Convert.ToString(page);

XmlAttribute countAttr = doc.CreateAttribute("count");
countAttr.Value = System.Convert.ToString(count);

StringBuilder sb = new StringBuilder(1024);
StringWriter stringWriter = new StringWriter(sb);

XmlTextWriter writer = new XmlTextWriter(stringWriter);

return sb.ToString();

Version 2 :

private static List<Entity> GetTotalRecordsFetchXML(OrganizationServiceProxy orgProxy, string fetchXML)
XDocument xDocument = XDocument.Parse(fetchXML);
var fetchXmlEntity = xDocument.Root.Element("entity").ToString();

EntityCollection entityColl = new EntityCollection();
List<Entity> lstEntity = new List<Entity>();
int page = 1;

entityColl = orgProxy.RetrieveMultiple(new FetchExpression(
string.Format("<fetch version='1.0' page='{1}' paging-cookie='{0}'>" + fetchXmlEntity + "</fetch>",
SecurityElement.Escape(entityColl.PagingCookie), page++)));

while (entityColl.MoreRecords);

return lstEntity;

List is Locked. Cannot perform this action error while trying to remove marketing list member using RemoveMemberListRequest in Dynamics 365 (CRM)

Recently we got the below error while trying to remove the marketing list member from a marketing list.

This occurs if the marketing list is locked. The marketing list gets locked if it is Dynamic Marketing List. However, we are getting this issue on our Static marketing lists. Later we realized that those static marketing lists were created using Copy To Static ribbon button. When a Dynamic Marketing List is created the locked field value is false. However it gets set as true when we convert it to Static using Copy To Static functionality.

Changing the Locked field value as No fixed the issue.

Hope this helps..

Missing RemoveListMembersListRequest in CRM.

In one of our recent implementations, we were working with Marketing List which could be in millions.

So we had the recent request wherein we split the marketing list into groups.

For adding members to a marketing list we have the following request


which is quite efficient as we can add multiple members in a single request.

However, when it comes to removing a member from marketing, we do not have a corresponding Remove request like RemoveListMembersListRequest.

We only have RemoveMemberListRequest, which only removes 1 member at a time, which is highly inefficient when we are taking in consideration large number of records.

Kindly vote up for this idea !!

System.Security.SecurityException: That assembly does not allow partially trusted callers while using HttpUtility.UrlEncode in CRM


We got the below error in one of our Sandboxed Plugins

“System.Security.SecurityException: That assembly does not allow partially trusted callers”.

We realised it was because of using System.Web.HttpUtility class

We replaced it with EscapeDataString method and this fixed the issue.

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;
