For a specific column I add a combo-button and a number of constraints. Example: pColumnEnabled->GetEditOptions()->AddConstraint("Yes", TRUE);
pColumnEnabled->GetEditOptions()->AddConstraint("No", FALSE); Now I create a custom CXTPReportRecord-class. For the 'Enabled' column I want to add an item like this:
AddItem(new CReportRecordItemEnabled(FALSE));
When I do that, I want the report control to automatically set the text "No". How?!
I managed to do this by overriding Populate() and manually updating the text, but this approach is very ugly. ------------- PokerMemento - http://www.pokermemento.com/ |

Hi; I did this by calling pConstraints->SetCurrent(xxx); SetValue(pConstraints->GetAt(xxx)); in the constructor of my custom item class. ------------- Martin Product: Xtreme Toolkit v 19.0.0, new Projects v 19.1.0 Platform: Windows 10 v 1909 (64bit) Language: VC++ 2017 |

Where do you get the pointer to the constraints? ------------- PokerMemento - http://www.pokermemento.com/ |

| AddConstraint return CXTPReportRecordItemConstraint* or use CXTPReportRecordItemConstraint* pConstraint = GetEditOptions(NULL)->FindConstraint( specific Value ); |

No, that won't work when the constraints are set per column! I need to access the columns, and then retrieve the constraints:
GetColumns()->GetColumn(3)->GetEditOptions()...
But it cannot be done inside the constructor of a report record :( ------------- PokerMemento - http://www.pokermemento.com/ |

You can do it just after you add a column to report itself -
CXTPReportColumn* pColumnStatus = wndReport.AddColumn(...) if (pColumnStatus)
pColumnStatus->GetEditOptions()->AddConstraint(...) |

Yes, but you're missing the point here. I believe there is a design flaw in XTP 12.1.1 (and earlier). Please, let me clarify what I mean.
Q: Record items do not auto-set their corresponding constraint value when CXTPReportControl is being populated. Is this by design?
I add a record:
m_wndReport.AddRecord(new CMyRecord(FALSE));
In the constructor of this record:
CMyRecord::CMyRecord(BOOL enabled)
{
AddItem(new CMyRecordItem(enabled));
}
In the constructor of that item:
CMyRecordItem::CMyRecordItem(BOOL enabled)
: CXTPReportRecordItemText()
, m_enabled(enabled)
{
// Here it should be possible to set a value that tells XTP to
// look up m_enabled in the constraints when populating the control!
}
When I populate the report control I expect this item to automatically lookup its constraints and set the corresponding text! This does not happen, and I am forced to override Populate() and add ugly functions to get the desired behavior.
Hence, either I'm missing something here, or the design is flawed. ------------- PokerMemento - http://www.pokermemento.com/ |

No - it works logically. Let's make a sample base on ReportSample - TaskListView:
class CTaskRecord : public CXTPReportRecord{ protected : class CTaskItemType : public CXTPReportRecordItem{ public:CTaskItemType(BOOL bSharedTask) { m_taskType = bSharedTask; } void OnConstraintChanged(XTP_REPORTRECORDITEM_ARGS* /*pItemArgs*/, CXTPReportRecordItemConstraint* pConstraint){ if (pConstraint)m_taskType = (BOOL) pConstraint->m_dwData; } CString GetCaption(CXTPReportColumn* pColumn) { CXTPReportRecordItemConstraint* pConstraint = pColumn->GetEditOptions()->FindConstraint(m_taskType); ASSERT(pConstraint); return pConstraint->m_strConstraint;} BOOL m_taskType; }; .............................
CTaskRecord::CTaskRecord( BOOL bSharedTask, TaskImportance taskImportance, BOOL bHasAttachment, TaskStatus taskStatus, CString strSubject, COleDateTime odtDueDate, int nComplete, CString strCategories){ AddItem( new CTaskItemType(bSharedTask));AddItem( new CTaskItemImportance(taskImportance));AddItem( new CTaskItemAttachment(bHasAttachment));AddItem( new CTaskItemStatus(taskStatus));AddItem( new CXTPReportRecordItemText(strSubject));AddItem( new CTaskItemDueDate(odtDueDate));AddItem( new CTaskItemComplete(nComplete));AddItem( new CXTPReportRecordItemText(strCategories));} int CTaskListView::OnCreate(LPCREATESTRUCT lpCreateStruct){ if (CXTPReportView::OnCreate(lpCreateStruct) == -1) return -1;CXTPReportControl& wndReport = GetReportCtrl(); wndReport.GetImageManager()->SetIcons(IDB_BMREPORT, 0, 0, CSize(16, 16)); CXTPReportColumn* pColumnType = wndReport.AddColumn( new CXTPReportColumn(COLUMN_TYPE, _T("Type"), 48, TRUE, 0));pColumnType->GetEditOptions()->AddConstraint(_T( "Yes"), TRUE);pColumnType->GetEditOptions()->AddConstraint(_T( "No"), FALSE);pColumnType->GetEditOptions()->m_bConstraintEdit = TRUE; pColumnType->GetEditOptions()->m_bAllowEdit = TRUE; pColumnType->GetEditOptions()->AddComboButton(); ...................... wndReport.AddRecord( new CTaskRecord(TRUE, taskImportanceNormal, TRUE, taskStatusInProgress, _T("Support Email: About tooltips"), dtNone, 70, _T("")));wndReport.AddRecord( new CTaskRecord(TRUE, taskImportanceNormal, TRUE, taskStatusNotStarted, _T("Support Email: Docking Pane ToggleDocking"), dtNone, 0, _T("")));wndReport.AddRecord( new CTaskRecord(TRUE, taskImportanceHigh, TRUE, taskStatusNotStarted, _T("Feature Request: New Event for CommandBars"), dtNow, 0, _T("")));wndReport.AddRecord( new CTaskRecord(TRUE, taskImportanceHigh, TRUE, taskStatusCompleted, _T("Support Email: Help Taskpanel And ShortcutBar"), dtNow, 100, _T("")));wndReport.AddRecord( new CTaskRecord(TRUE, taskImportanceNormal, FALSE, taskStatusCompleted, _T("Support Email: RE: Docking Pane Window Overlapping Issues"), dtNow, 100, _T("")));wndReport.AddRecord( new CTaskRecord(TRUE, taskImportanceNormal, FALSE, taskStatusCompleted, _T("Support Email: CXTPPropertyGridItem"), dtNone, 100, _T("")));wndReport.AddRecord( new CTaskRecord(TRUE, taskImportanceNormal, TRUE, taskStatusCompleted, _T("Support Email: Toolbar Oddity"), dtNone, 100, _T("")));wndReport.AddRecord( new CTaskRecord(TRUE, taskImportanceNormal, TRUE, taskStatusCompleted, _T("Support Email: CXTPTabControl"), dtNone, 100, _T("")));wndReport.AddRecord( new CTaskRecord(FALSE, taskImportanceNormal, TRUE, taskStatusInProgress, _T("Support Email: Menus go wrong if another form has topmost setting"), dtNone, 10, _T("")));wndReport.AddRecord( new CTaskRecord(FALSE, taskImportanceNormal, TRUE, taskStatusInProgress, _T("Support Email: Update Xtreme Suite from 8.6 to 8.7"), dtNone, 0, _T("")));wndReport.AddRecord( new CTaskRecord(TRUE, taskImportanceLow, TRUE, taskStatusInProgress, _T("Support Email: Bug in Tree-View on Label Edit"), dtNone, 0, _T("")));....................
Now your first column automatically set Caption according of passed BOOL value (e.g. CTaskRecord(FALSE,...)

Ok, then the answer is; I've missed something :P
