GetSelectedConstraintData question

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   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;}
