Setting value in ms crm

I have seen many question in MS CRM Development where Consultant asking for MS CRM 2011 data type related question, like how to set lookup field, how to set/retrieve optionset value. so I thought to write code to show how we can set different data type field in MS CRM 2011.

Below is the example to create account using late bound

Entity _Account = new Entity();
_Account.LogicalName = “account”;
//setting text field
_Account.Attributes.Add(“name”, “Myaccount123″);

//setting optionset field
_Account.Attributes.Add(“accountcategorycode”, new OptionSetValue(2));

//setting datetime field
_Account.Attributes.Add(“new_collectiondate”, new DateTime(2012, 3, 25));

//setting currency field
_Account.Attributes.Add(“creditlimit”, new Money(300));

//setting lookup
_Account.Attributes.Add(“parentaccountid”, new EntityReference(“account”, new Guid(“XXX-XXX……..”)));

//setting decimal
_Account.Attributes.Add(“new_executivecommission”, new Decimal(55.5));

//setting boolean
_Account.Attributes.Add(“new_isbilled”, true);

service.Create(_Account);

Retrieve MS CRM fields using late bound

In this post I am going to Show how can we fetch value from different data type fields.

Entity _Account = service.Retrieve(“account”, new Guid(“XXXXX”), new ColumnSet(new string[] { “name”, “accountcategorycode”, “new_collectiondate”, “creditlimit”, “parentaccountid”, “new_executivecommission”, “new_isbilled” }));

//To fetch string value

string Name = _Account["name"].ToString();

//To fetch optionset selected value

int OptionSetValue = ((OptionSetValue)_Account["accountcategorycode"]).Value;

//To fetch date time field value

DateTime CollectionDate = ((DateTime)_Account["new_collectiondate"]).Date;

//To fetch money field value

decimal Creditlimit = ((Money)_Account["creditlimit"]).Value;

//To fetch decimal field value

decimal Executivecommission = (decimal)_Account["new_executivecommission"];

//To fetch lockup field

Guid ParentAccountID = ((EntityReference)_Account["parentaccountid"]).Id;

//To fetch Boolean field

Boolean IsBilled=(Boolean)_Account["new_isbilled"];

MS CRM 2011 Entity Images

PreEntityImages :(Gets the properties of the primary entity before the core platform operation has begins)

PreEntityImages used to capture the data when the form loads. That is the data which is present by default when the form loads.  The syntax for using the PreEntityImages in CRM 2011 is changed as compared to CRM 4.0.

Note:The PreEntityImages cannot be registered for “create” operation.

Syntax Used in CRM 2011 :
=======================

Suppose you registered the Plugin and added a Image with name “PreImage ”

public EntityImageCollection PreEntityImages { get;}
PostEntityImages : (Gets the properties of the primary entity after the core platform operation has been completed. )

The PostEntityImages contains the attributes value which are finally changed. We can capture the changed data before the database operation takes place. And can do any kind of validation based on the changed data.

Note: PostEntityImages can only be registered  for Update message and cannot be registered on Create message.

Syntax Used in CRM 2011 :

Suppose you registered the Plugin and added a Image with name “PostImage ”

Syntax:
=========

public EntityImageCollection PostEntityImages { get; }
