But how to get value in "annotationid (guid)" filed?

Mar 12, 2013 at 9:32 AM
  I'm using this control first time.I have tried everything well i.e. passing parameters and all.But silverlight control is not loading on form.I think it's because the "mcg_annotationidguid" field on my form is empty.When this field will get assigned?
 I'm not able to get when this field will contain value?Initially on create mode this field is blank.
