Here is an example of a send to an email that is entered by the user in the form workflow:

The email service is just a method in our repository which sends off an email using the Xslt file specified in the properties but this shows being able to get the value of a field out in a workflow in XML format.

Hi Paul,

I use a quick (and dirty) helper method to grab content of a form field by field caption

public static RecordField GetByLabel(this Record record, string labelName)

{

return record.RecordFields.Values.Where(value => value.Field.Caption == labelName).FirstOrDefault();

}

You already have the record from the public override WorkflowExecutionStatus Execute(Record record, RecordEventArgs e)

Can use the ValuesAsString() method on the returned record field to get a string value e.g.

string recipient = CogFormHelpers.GetByLabel(record, EmailFieldLabel).ValuesAsString(); 

where EmailFieldLabel is the caption of the email field e.g. "Email Address"
