Overriding Records per page count for Microsoft Dynamics CRM 4.0

I've decided to use idea and code from one of my previous posts.

1. Add field to user entity which will contain count of records to show.
2. Replace system-defined count of records with value from 1 trough catching and handling Execute message.


Code of the plugin:

using System;
using System.Collections.Generic;
using System.Text;
using Microsoft.Crm.Sdk;
using System.Xml;
using Microsoft.Crm.SdkTypeProxy;
using Microsoft.Crm.Sdk.Query;

namespace RecordPerPage
public class RecordCounterExtender : IPlugin
#region IPlugin Members

public void Execute(IPluginExecutionContext context)
if (context.MessageName == "Execute" && context.InputParameters.Contains("FetchXml"))
//I create a crmservice instance
ICrmService crmservice = context.CreateCrmService(true);

//I form a query to retrieve field with count of records
TargetRetrieveDynamic target = new TargetRetrieveDynamic();
target.EntityId = context.UserId;
target.EntityName = EntityName.systemuser.ToString();

RetrieveRequest request = new RetrieveRequest();
request.ColumnSet = new ColumnSet(new string[] { "new_recordscount" });
request.Target = target;
request.ReturnDynamicEntities = true;

//I retrieve field
DynamicEntity currentuser = (DynamicEntity)((RetrieveResponse)crmservice.Execute(request)).BusinessEntity;

//If the field is empty it would not be in response
//and this must be handled
if (currentuser.Properties.Contains("new_recordscount"))
//I create document to manipulate request query
XmlDocument indoc = new XmlDocument();

//There can not be such attribute
//and this must be handled
if (indoc.DocumentElement.Attributes["count"] != null)
//I replace standard value with field from user form
indoc.DocumentElement.Attributes["count"].Value = ((CrmNumber)currentuser["new_recordscount"]).Value.ToString();
//and return modified request to the context
context.InputParameters["FetchXml"] = indoc.OuterXml;
