Get Constraint assoziated Data from Combo

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

Hi there,

i�m facing problems in retrieving the assoziated constraint data from an inplace combo on a CXTPReportControl. While adding the data is no problem i find that retrieving is absolutly impossible. Here is the code snipped:

    CXTPReportRecordItemEditOptions *m_pEditOptions;
    m_pEditOptions = pColumn->GetEditOptions();
    m_pEditOptions->m_bAllowEdit = false;
    m_pEditOptions->m_bConstraintEdit = false; 
    m_pEditOptions->AddComboButton();
    m_pEditOptions->AddConstraint(_T("Name"),1);
    m_pEditOptions->AddConstraint(_T("Surname"),2);

I receive the notification for the changed value using 
    ON_NOTIFY(XTP_NM_REPORT_VALUECHANGED, IDC_LISTPARAM, EditItemPARAM)

While the recorditem is holding the new string value after edit the item is NOT holding the associated data value

CXTPReportRecordItemText *pItem =   dynamic_cast<CXTPReportRecordItemText*>(pItemNotify-&a mp;g t;pItem);

pItem->GetValue() success (holds the selected text value)
pItem->GetItemData() fails (always 0)

Questions:
1.) Why does the inplace combo set the text value but not the data value ?
2.) How do i retrieve the selected index or the selected constraint itself if NOT using enum types (cannot handle this here cause the content of the inplacebutton changes with every edit)

Would be really happy if someone can answer these questions...

Jan

	Fixed the problem by adding an own implementation of CXTPReportRecordItem: Here is the code snipped: class MyCustomReportRecordItem : public CXTPReportRecordItem { virtual void OnConstraintChanged(XTP_REPORTRECORDITEM_ARGS* pItemArgs, CXTPReportRecordItemConstraint* pConstraint) { if(pConstraint) { m_dwData = pConstraint->m_dwData; m_strCaption = pConstraint->m_strConstraint; } } };
