I handle XTP_NM_REPORT_VALUECHANGED. Inside my handler I want to retrieve the data of the selected constraint.

GetSelectedConstraintData always returns -1. Is this a bug? How do I get the associated data?

(I know I can loop through the constraints and compare their string values, but that is very ugly and not reliable.)

I really need help with this. In OnReportValueChanged(...):

// TODO: It should be possible to get the constraint data without string comparison!
   BOOL isEnabled = FALSE;
   int numberConstraints = pItemNotify->pColumn->GetEditOptions()->GetConstraints()->GetCount();
   for (int i = 0; i < numberConstraints; ++i)
   {
    CXTPReportRecordItemConstraint* pConstraint = pItemNotify->pColumn->GetEditOptions()->GetConstraints()->GetAt(i);
    if (pItemString->GetValue() == pConstraint->m_strConstraint)
    {
     isEnabled = static_cast<BOOL>(pConstraint->m_dwData);
     break;
    }
   }

It should be possible to get the constraint data immediately, without this ugly code! Any ideas?

base class function

AFX_INLINE DWORD CXTPReportRecordItem::GetSelectedConstraintData(XTP_REPORTRECORDITEM_ARGS* /*pItemArgs*/) {

return DWORD(-1);} - do nothing, derived class can do that you wants - see function

DWORD CXTPReportRecordItemVariant::GetSelectedConstraintData(XTP_REPORTRECORDITEM_ARGS* pItemArgs)

example - in TaskListView from ReportSample app

class CTaskItemImportance : public CXTPReportRecordItem

{

public:

CTaskItemImportance(TaskImportance taskImportance){SetImportance(taskImportance);}

void OnConstraintChanged(XTP_REPORTRECORDITEM_ARGS* /*pItemArgs*/, CXTPReportRecordItemConstraint* pConstraint){SetImportance((TaskImportance)pConstraint->m_dwData);}

DWORD GetSelectedConstraintData(XTP_REPORTRECORDITEM_ARGS* /*pItemArgs*/){return m_taskImportance;}
