Cancel a Contract in Microsoft Dynamics CRM 2011 Using .NET or Jscript

This illustration shows how to cancel a contract in Microsoft Dynamics CRM 2011  with CancelContractRequest.   This example will be given in Jscript (SOAP) and in C# (.NET).
    Ok, here is what the code looks like!
    First in C#:

    CancelContractRequest req = new CancelContractRequest();
    req.ContractId = new Guid("F11D5D0B-58EF-E011-8EE5-1CC1DEE89A95");
    req.CancelDate = DateTime.Now;  
    OptionSetValue o = new OptionSetValue();
    o.Value = 5;
    req.Status = o;
    CancelContractResponse resp = (CancelContractResponse)service.Execute(req);
    

    If you need help instantiating a service object in .NET within a plugin check out this post:

    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 posthttp://mileyja.blogspot.com/2011/07/using-jscript-to-access-soap-web.html

           // potential for functions to be overwritten due to a duplicate name when the library is loaded.

    To understand how to parse the response please review my post on using the DOM parser.
    Now you can call the SDK.SAMPLES.CancelContractRequest  function from your form jscript handler.
    Thats all there is to it!

    1. Cancellation of A Contract : The timeshare agreement, or its associated with documentation, should tell you the details you need to know, such as how to go about canceling the contract. There may be a type for you to complete or you may just have to create a correspondence. In all possibility, this content is hidden in your documentation, so look through everything. They are needed by law to provide you this details, so it is in there.
