Hi, since we changed our version to the 15.31 we now have this different behavior : Populate method now call a selection clear that ends in a notification to the listener of the message XTP_NM_REPORT_SELCHANGED. This was not the case with the previous version we used, the 15.13.

We have to embrace our code with a lock counter to avoid reacting to selection change notification.

selectionLockCount++;
_report.Populate();
selectionLockCount--;

void OnSelectionChanged(NMHDR* pNotifyStruct, LRESULT* pResult)
{
if  (selectionLockCount == 0)
{
...
}
}

Hope that knowing that might help other programmers.

I changed to 15.3.1 from 13.3.1 just now.

Have the same problem. App crashes because of this call.
I use a CXTPReportView which has a CXTPReportControl.
I do not derive from CXTPReportControl so i can not use your solution.

I looked at the added functionality in the Populate function and i see some added Behavior functions?!

Just added this after creating the CXTPReportView.

//m_pProjectTreeView is derived from CXTPReportView.
// Obtain the target report
//CXTPReportControl* CProjectTreeView::GetTargetReport()
//{
//   return &(GetReportCtrl());
//}

  m_pProjectTreeView->GetTargetReport()->GetBehavior()->Notifications->Populate->bSelectionChanged = false;


This will do the trick. Smile

I do not know what GetBehavior()->Notifications->Populate->bSelectionChanged does.
But as far as i can tell everything works just fine when its false.Wacko

Hi;

Have you tried to set

CXTPReportControl::m_bInitialSelectionEnable=FALSE;
