How can I change ORDER() in a grid? by ChrisRChamberlain
faq184-446
Posted: 1 Feb 01

Add as many new form properties as you have indexed fields in your grid that intend to set to be ORDER(), ie .lGrid1Asc1, .lGrid1Asc2, .lGrid1Asc3 etc.

In the Grid1.Column1.Header1.Click() event put:-

lcAlias = ALIAS() && Save current Alias - optional
SELE TABLENAME && .RecordSource of grid - optional

IF THISFORM.lGrid1Asc1
    SET ORDER TO TAG tagname ASCE
    THISFORM.lGrid1Asc1    = .F.    
ELSE
    SET ORDER TO TAG tagname DESC
    THISFORM.lGrid1Asc1    = .T.
ENDI

GO TOP && Optional

WITH THISFORM.grid1
    .SetAll([ForeColor],RGB(0,0,0),[Header]) && Optional - highlights indexed column
    .Column1.Header1.ForeColor = RGB(0,0,255) && Optional - highlights indexed column
    .Refresh()
ENDWITH

SELE (lcAlias) && Restore current Alias - optional

Clicking on the header will select the index and toggle it from ascending to descending, Windows Explorer style. The header colour will also change to indicate which column currently is ORDER().

You can then modify and repeat the code in the other columns.
