Changed behaviour of Populate method

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

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

	Hi; Have you tried to set CXTPReportControl::m_bInitialSelectionEnable=FALSE;
