I recently turned on sort for child by using SetSortRecordChilds(TRUE);
and now get an ASSERT in the follow function.
CXTPReportRow* CXTPReportRow::GetNextSiblingRow() const
{ if (!m_pParentRows) return 0; if (m_nChildIndex == -1) return 0;ASSERT(m_pParentRows->GetAt(m_nChildIndex) == this); if (m_nChildIndex < m_pParentRows->GetCount() - 1) return m_pParentRows->GetAt(m_nChildIndex + 1); return 0;}
After doing a little debug, it seem that the record it is getting the
itself because the record has moved but the index is the same. If I ignore all the ASSERT the program and sort execute correctly. If I take out the code that moves the children around it works correctly. ------------- It's horrible to see a family ripped apart by some as simple as.... wild dogs. |

Hi,
We have the same problem.
It seems to be linked to the sorted column.
This error comes when you add a child record, with the SetSortRecordChilds(TRUE) activated, and with one or more columns sorted.
If no column is sorted, the problem doesn't occur.
We think that's a bug of the Report Control.

Hi,
In fact, there's really a bug in Release mode :
  Hope to get an answer now...

While looking inside using the debugger, it seems that there's a confusion between these Rows arrays : - CXTPReportRows * m_pPlainTree - CXTPReportRows* m_pRows
 They both hold pointers to the same object, but the CXTPReportRow class can hold only one parent Rows.I have tried to force the refresh of indexes, using a class overriden from the CXTPReportControl one :
void CMyXTPReportControl::RefreshDisplay()
{ m_bRefreshIndexes = TRUE; Populate();
m_pHeaderRows->RefreshChildIndices(TRUE);
m_pRows->RefreshChildIndices(TRUE); m_pFooterRows->RefreshChildIndices(TRUE); m_pPlainTree->RefreshChildIndices(TRUE);
m_arrScreenRows.RefreshChildIndices(TRUE);
} void CMyXTPReportControl::RefreshSort()
{ m_bRefreshIndexes = TRUE; ReSortRows();
m_pHeaderRows->RefreshChildIndices(TRUE);
m_pRows->RefreshChildIndices(TRUE); m_pFooterRows->RefreshChildIndices(TRUE); m_pPlainTree->RefreshChildIndices(TRUE);
m_arrScreenRows.RefreshChildIndices(TRUE);
} But it just moved the problem...

Hi,
I have just downloaded and checked this issue with the MFC Codejock Release 12.0.0.
There is still the same problem.
Have you been able to reproduce this problem ? ------------- Sergio |

Hi, Now, I know more about this issue.This problem doesn't occur if you clear the sort before modifying records.
Here is my code :
============
////////////////////////////////////////////////////
// Clear sort //////////////////////////////////////////////////// int nTopRow = m_pRP->GetTopRowIndex(); // store the first displayed row index CXTPReportColumnOrder* pSortOrder = m_pRP->GetColumns()->GetSortOrder(); CArray<CXTPReportColumn*, CXTPReportColumn*> aReportColumns;
CArray<BOOL, BOOL> aSortAscending; for (int i=0; i<pSortOrder->GetCount(); i++) { aReportColumns.Add(pSortOrder->GetAt(i)); aSortAscending.Add(pSortOrder->GetAt(i)->IsSortedIncreasing()); } m_pRP->FClearSort();
////////////////////////////////////////////////////
// ... // Modify records and child records // ... //////////////////////////////////////////////////// ////////////////////////////////////////////////////
// Restore sort //////////////////////////////////////////////////// for (int i=0; i<aReportColumns.GetSize(); i++) { m_pRP->GetColumns()->InsertSortColumn(aReportColumns.GetAt(i)); aReportColumns.GetAt(i)->SetSortIncreasing(aSortAscending.GetAt(i)); } m_pRP->FRefreshSort(); m_pRP->SetTopRow(nTopRow); // Restore the index of the first displayed row of the report ------------- Sergio |

Hi, Serqio. I solve this problem by calling ReSortRows() after Populate() (Xtreme ToolkitPro v11.2.0) void CReportControlEx::Populate() { CXTPReportControl::Populate(); ReSortRows(); } |

Hi Zitz,
I just read your answer, sorry for the long delay. Yes, I confirm that ReSortRows() works and fix the problem. (We did the same.) Thank you for your answer. Regards, ------------- Sergio |
