I want to know the bounded cursor of and Grid, this grid will be in a custom Class, it could be easy if I check the RecourdSource property, but I want to know the cursor binded when I'm using RecordSourceType = 4. Is there an easy way?, or must I have to split the RecordSource? if I must do it which event must I check?

The Grid class would pay attention in Dynamical re-asigment of RecordSource:

   WITH ThisForm.eGridSelection && My custom Grid
         .RecordSource = "SELECT * from Customer INTO CURSOR "+SYS(2015)
         .RecordSourceType = 4
   ENDWITH
