In our application, we have a CXTPReportControl containing a potentially large number of rows. The problem I am having is that it appears that when a row is added into the tree, if the user has collapsed the tree, it gets expanded automatically. I would like to prevent this from happening. I put some breakpoints in the code, and CXTPReportRow::SetExpanded does not appear to be called...

So does anybody have any ideas on why my control is being expanded? Does anybody else have the same behavior?

Hi,

I am using ActiveX but I think it has same problem... Call Populate automatically expands all collapsed rows.

And to all other MFC users, why don't you reply on this? Only nagging about bugs/problems isn't what a forum is about, helping your fellow users thats what's a forum is for !!!!

I have just updated my project to use the latest version of the toolkit (13.4.2) and still see the same behaviour. Is there any way to have collapsed rows NOT expand?

I am also noticing the same problem. Are there any updates on this? Can we force-collapse the rows after we run the Populate command? If so, how do we determine if the rows were originally collapsed?

My solution, if you can call it that, was to subclass the report control, and in my populate, get a list of all collapsed rows, then recollapse them, unless they contained new records, in which case, leave them expanded
CSubclassReportControl
{
...
    std::list<CXTPReportRecord*> m_NewRecords;
    CXTPReportRecord* AddRecord(CXTPReportRecord* pRecord)
    {
        POSITION pos = m_NewRecords.Find(pRecord);
        if (!pos)
            m_NewRecords.AddTail(pRecord);
        return __super::AddRecord(pRecord);
    }

    void Populate()
    {
        CList<CString> collapsedRows;
      CXTPReportRows *pRows = GetRows();
      for (int i = 0; i < pRows->GetCount(); i++)
        {
            CXTPReportRow *pRow = pRows->GetAt(i);
            if (pRow && pRow->IsGroupRow() && !pRow->IsExpanded())
            {
                CXTPReportGroupRow* pGroupRow = (CXTPReportGroupRow*) pRow;
                collapsedRows.AddTail(pGroupRow->GetCaption());
            }
        }
        __super::Populate();
        pRows = GetRows();
      for (int i = 0; i < pRows->GetCount(); i++)
        {
          CXTPReportRow *pRow = pRows->GetAt(i);
          if (pRow && pRow->IsGroupRow())
            {
              CXTPReportGroupRow* pGroupRow = (CXTPReportGroupRow*) pRow;
              CString caption = pGroupRow->GetCaption();
                POSITION pos = collapsedRows.Find(caption);
                if (pos)
                {
                    bool foundNew = false;
                    CXTPReportRows *pChilds = pRow->GetChilds();
                    for (int j = 0; j < pChilds->GetCount(); j++)
                  {
                  CXTPReportRow *pChild = pChilds->GetAt(j);
                        if (pChild)
                      {
                      CXTPReportRecord* pRecord = pChild->GetRecord();
                            POSITION pos = m_NewRecords.Find(pRecord);
                            if (pos)
                            {
                                m_NewRecords.RemoveAt(pos);
                                foundNew = true;
                                break;
                            }
                        }
                    }
                  if (!foundNew)
                  {
                      pGroupRow->SetExpanded(FALSE);
                  }
                    collapsedRows.RemoveAt(pos);
                }
            }
        }
        m_NewRecords.RemoveAll();
    }
};

Hi,

currently Populate() does not keep the current expand state. All rows are destroyed and the recreated. I look into a solution for the next release.
