Answer 1

In your code-behind, you should be able to do the following:

// get a new entity
var attachment = new Attachment();

// initialize attachment properties as needed
this.ddsContAttachment.DataView.Add(attachment);

// when ready to submit the new record...
this.ddsContAttachment.SubmitChanges();
