How can change Group Condition On Report Runtime

athena

Hi,

How can change group condition parameters at report runtime on fr4.

This source is correctly run on v.2.54 but can not run v.4.0
GroupHeader1.OnBeforPrint
begin
if WF_LIS_GRP = 02 then GroupHeader1.Condition := '[Musdos_CDSET."MUSDOS_ACE_KOD"]';
if WF_LIS_GRP = 03 then GroupHeader1.Condition := '[Musdos_CDSET."MUSDOS_SIR_KOD"]';
if WF_LIS_GRP = 04 then GroupHeader1.Condition := '[Musdos_CDSET."MUSDOS_FAT_KOD"]';
end;

our changed source for v4.0 this but we get the Error this source
GroupHeader1.OnBeforPrint
begin
if WF_LIS_GRP = 02 then GroupHeader1.Condition := '<Musdos_CDSET."MUSDOS_ACE_KOD">';
if WF_LIS_GRP = 03 then GroupHeader1.Condition := '<Musdos_CDSET."MUSDOS_SIR_KOD">';
if WF_LIS_GRP = 04 then GroupHeader1.Condition := '<Musdos_CDSET."MUSDOS_FAT_KOD">';
end;

gordk

the condition property is a string
if you look at the object inspector after setting a datafield as a condition
you will see the condition looks like this
Musdos_CDSET."MUSDOS_ACE_KOD"
so you must use the appropriate number of ' and functions to end up with that result.
ie
condition := '<Musdos_CDSET.'+quotedstr(MUSDOS_ACE_KOD);
