I find it a lot easier to have the recordsource in place before the grid is initiated (ie. create the cursor in form.load or your data environment object etc.) and have the grid designed at runtime.

When you need to change the recordsource of the grid (assuming the same grid layout), simply :

thisform.mygrid.recordsource = ""

SELECT * ;
FROM mytable ;
WHERE mycondition ;
INTO mycursor READWRITE

thisform.mygrid.recordsource = "mycursor"

That will keep all formatting, methods etc. in the grid.
