Virtual Report Control and MoveFirstRow

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

   We're having trouble using CXTPReportNavigator::MoveFirstRow with a report control in virtual mode. 

In MoveFirstRow (and MoveLastRow), you immediately check first to see if the currently focused row is already the first (or last) row. It looks like a virtual report control always returns the same virtual row object, and so when you compare the address between the result of GetAt(0) and the focused row, they are always the same. 

Is this a bug, or is there some other method I use for selecting the First (or Last) row in the report?

PS We're using version 13.1.0

	Sure it does not works in virtualmode - but you can use PageUp - PageDown navigation. Need to add special virtual mode navigation for cases: VK_HOME and VK_END

	Please try this code - I can't SVN it until 13.2 will be official released but you can build your own dll now and test your case: void CXTPReportNavigator::MoveFirstRow(BOOL bShiftKey, BOOL bControlKey) { if (!m_pReportControl) return; if (m_pReportControl->IsMultiSelectionMode()) bControlKey = TRUE; CXTPReportRow* pFirst = m_pReportControl->m_pRows->GetAt(0); if (m_pReportControl->IsVirtualMode()) m_pReportControl->SetFocusedRow(pFirst, bShiftKey, bControlKey); else if (pFirst != m_pReportControl->GetFocusedRow()) m_pReportControl->SetFocusedRow(pFirst, bShiftKey, bControlKey); m_pReportControl->UnselectGroupRows(); } void CXTPReportNavigator::MoveLastRow(BOOL bShiftKey, BOOL bControlKey) { if (!m_pReportControl) return; if (m_pReportControl->IsMultiSelectionMode()) bControlKey = TRUE; CXTPReportRow* pLast = m_pReportControl->m_pRows->GetAt(m_pReportControl->m_pRows->GetCount() - 1); if (m_pReportControl->IsVirtualMode()) m_pReportControl->SetFocusedRow(pLast, bShiftKey, bControlKey); else if (pLast != m_pReportControl->GetFocusedRow()) m_pReportControl->SetFocusedRow(pLast, bShiftKey, bControlKey); m_pReportControl->UnselectGroupRows(); } I don't put this piece in https://forum.codejock.com/uploads/DemoVersion/ReportControlMFCUpdated.rar but other code is up to date to build dll
