You can add property cCursorName to your grid class.

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

>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?
