How to change parent of child records?

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

   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
