You can get the row index and column index by utilising the static methods getRowIndex() and getColumnIndex() which are located in the GridPane class.

System.out.println("Row: "+ GridPane.getRowIndex(text1));
System.out.println("Column: "+ GridPane.getColumnIndex(text1));

See for reference: http://docs.oracle.com/javafx/2/api/javafx/scene/layout/GridPane.html#getRowIndex(javafx.scene.Node)
