It took me a while to figure this out but here's what is working very
well for me. I had problems getting the radio buttons to work (C4b bug?) so
I created my own alternative using three checkboxes with icons. For each
check box I have true value = 1 and false = 0. In the Accessed embed for
each check box I have code like this:
Loc:WhseNoFltBurl=0 !Unlatches this unselected "radio button"
Loc:WhseNoFltFlue=0 !Unlatches this unselected "radio button"
BRW3.ApplyFilter
ThisWindow.Reset(1)
In the ApplyFilter embed for the browse I am filtering I have the following
code:
IF Loc:WhseNoFltAll=1 THEN
BRW3.SetFilter('','2WhseNo')
END
IF Loc:WhseNoFltFlue=1 THEN
BRW3.SetFilter('BUS:WAREHOUSE_NO >= ''10000'' AND BUS:WAREHOUSE_NO <<=
''10999''','2WhseNo')
END
IF loc:WhseNoFltBurl=1 THEN
BRW3.SetFilter('BUS:WAREHOUSE_NO > ''30999'' AND BUS:WAREHOUSE_NO <<
''32000''','2WhseNo')
END
On this same browse I also have two other standard check boxes for
additional filters, Xplore for changing sort order and Query Wizard for
additional adhoc queries. Using this technique they all work together
perfectly in any combination. I also use GETINI and PUTINI to persist the
filter settings between sessions.
HTH.
