I have a form with a grid. The init of the form creates an empty cursor which serves as the grid's recordsource and assigns the appropriate controlsource to each column

CREATE CURSOR myCursor ........ etc
thisform.get_data()    && populate myCursor
WITH thisform.mygrid
     .recordsource = "myCursor"
     .column1.controlsource = "myCursor.field1"
                               .
     .columnN.controlsource = "myCursor.fieldN"
ENDWITH

There is a timer on the form which fires every two minutes.

Timer1.timer
thisform.get_data()

The get_data method rebuilds the data in myCursor

SELECT myCursor
ZAP
SCATTER NAME oRecord MEMO

SELECT blah blah INTO CURSOR crsTemp
SCAN
     oRecord.field1 = some value
     oRecord.fieldN = some value

     INSERT INTO myCursor FROM NAME oRecord
ENDSCAN

SELECT myCursor
GO TOP
thisform.myGrid.refresh

The init method runs fine and all the data is displayed correctly. However, after the timer fires there are times when the grid appears to be empty. I've verified that the cursor actually has data and that the grid's recordsource and column controlsources are correct.

If I simply press a down-arrow key the data in the grid appears and I'm at record 2.

I've found two different work-arounds to get the behavior I need

1. I changed my code to put the GO TOP after the grid refresh

2. At the beginning of the get_data method I move the focus away from the grid and then set the focus back to the grid at the end of the method.

This obviously isn't urgent since I've found work-arounds, but I am still curious.

Does anybody have an explanation as to why the data in grid doesn't show under my original code? Is this desired behavior? Is it a known anomoly (that I've run into for the first time because I've almost always refreshed data as a result of a button press that set focus outside the grid)

Thanks to all...........Rich
