Remove an Item From a Marketing Campaign in Microsoft Dynamics CRM 2011 Using .NET or Jscript

This illustration shows how to remove an item from a marketing campaign in Microsoft Dynamics CRM 2011 with RemoveItemCampaignRequest.  This example will be given in Jscript (SOAP) and in C# (.NET).

NOTE:  I do not like now the EntityId property of this request only asks for a GUID as it appears it could be a campaign activity, response, or any other type of entity attached to a marketing campaign.  This property should have been represented by an EntityReference object.

Ok, here is what the code looks like!

First in C#:

RemoveItemCampaignRequest req = new RemoveItemCampaignRequest();
// marketing campaign to remove an item from
req.CampaignId = new Guid("15C65044-541C-E111-8E08-1CC1DEF1353B");
//Guid for EntityID must represent an item attached to a campaign, in my case, I chose a target product
req.EntityId = new Guid("6FBC3543-1515-E111-8E08-1CC1DEF1353B");
RemoveItemCampaignResponse resp = (RemoveItemCampaignResponse)service.Execute(req);

Now here is the Jscript nicely formatted by the CRM 2011 SOAP formatter. Available at: http://crm2011soap.codeplex.com/

Now in Jscript


This example is asynchronous, if you want to learn how to make JScript SOAP calls synchronously please visit this post: http://mileyja.blogspot.com/2011/07/using-jscript-to-access-soap-web.html

To understand how to parse the response please review my post on using the DOM parser.

http://mileyja.blogspot.com/2011/03/microsoft-dynamics-crm-2011-parsing.html

Now you can call the SDK.SAMPLES.RemoveItemCampaignRequest function from your form jscript handler.

Thats all there is to it!
