Hi there,

I'm using CXTPReportControl with one column displayed as a tree style. I need to change the child records' parent dynamically. My logic is:

CXTPReportRecord *pItem ; // the child item to move to new parent

CXTPReportRecord *pOldParent = pItem->GetRecords()->GetOwnerRecord() ;

CXTPReportRecord *pNewParent ; // the target record to hold the child

pOldParent->RemoveRecord(pItem) ;

pNewParent->Add(pItem) ;

However, when I call pOldParent->RemoveRecord(pItem), the pItem would be released by "InternalRelease" internally in CXTPReportControl~~~

Is there any easy way for this? Anyone can help will be much appreciated.

The solution is from Codejock support:- (For anyone has the same problem)

Can try using TreeAddRef() method before removing an item from an old parent.

For example, the following work in our sample for me:

void CTreeViewDlg::OnOK()
{
CXTPReportRecord *pOldParent = m_wndReport.GetRecords()->GetAt(2);
CXTPReportRecord *pItem = pOldParent->GetChilds()->GetAt(0) ; // the child item to move to new parent
CXTPReportRecord *pNewParent = m_wndReport.GetRecords()->GetAt(0); // the target record to hold the child

pItem->TreeAddRef();
pOldParent->GetChilds()->RemoveRecord(pItem);
pNewParent->GetChilds()->Add(pItem);

m_wndReport.Populate();
//CDialog::OnOK();
}

Should be "InternalAddRef", there's no "TreeAddRef" in XTP 11.2.0
