TXBrowse():Refresh() will Scroll Up 1 line

[dutch]

Dear Antonio,

I use xHB.com Nov '07 with FWH 8.03.

When I put method TXBrowse():Refresh() the screnn will scroll up 1 line!. I feel every update data TXBrowse() will automatic :Refresh() even do not call :Refresh().

Do I understand correctly? If so, I have to remove very in the program ::Refresh()? Because when I call it TXBrowse() will alway scroll up 1 line.

Regards,
Dutch

Dutch,

Can we see how you have defined the browse?

No. It does not. If a cell is edited through xBrowse's methods, then that row only is refreshed automatically using the method DrawLine( .t. ). Also if we use xBrowse's inbuilt feature to sort columns and the edited column is a sorted column, then the browse calls Refresh() automatically instead of DrawLine( .t. ).

If we update the data directly then we need to refresh() or drawline(.t.) ourselves.
( Note: To refesh a single row, we can either use DrawLine( .t. ) or DrawSelect() or RefreshCurrent() in the latest version of xBrowse )

This is surprising. I never noticed it so far. I am very much interesed in knowing under what circumstances this happens.

Dear James,

This is my REDEFINE command. I try many time with :Refresh() at ON DBLCLICK, after edit the record and save the record will scroll up 1 line. If I remove :Refresh() and save. The record is refreshing and still the current line.

Dutch,

I am wondering if something in this function is causing the problem:

RsvnScr(.F.,,oDbf)

If you remove the call to that function does the browse still move up one record?
