Hi,
there seems to be a problem when using CXTPReportRecordItemPreviews (V10.4.0)
To reproduce:
1) enable preview with "Toggle Preview Mode".
2) After doing several clicks in some rows I always get a crash at " InternalAddRef();" in "void CXTPReportRecordItem::OnClick(XTP_REPORTRECORDITEM_CLICKARGS* pClickArgs)"
Apart from that a question:
m_pPreviewItem = new CXTPReportRecordItemPreview(m_HintText);
m_pPreviewItem->SetBold(true);
m_pPreviewItem->SetTextColor(RGB(255,0,0));
SetPreviewItem((CXTPReportRecordItemPreview*)m_pPreviewItem);
SetBold and SetTextColor have no influence for the preview display. Does this makes sense? Or do I have to change the metrics for display??
Greets,
Patrik

Hi again,
got the solution:
there was no column for a preview item - so I've modified the onclick method:
if (pClickArgs->pRow != NULL)
pClickArgs->pRow->InternalAddRef();
if (pClickArgs->pColumn != NULL)
pClickArgs->pColumn->InternalAddRef();
InternalAddRef();
pClickArgs->pControl->InternalAddRef();
....
if (pClickArgs->pRow != NULL)
pClickArgs->pRow->InternalRelease();
if (pClickArgs->pColumn != NULL)
pClickArgs->pColumn->InternalRelease();
InternalRelease();
pClickArgs->pControl->InternalRelease();
But I'm not sure if there could be other problems after the change!
Greets,
Patrik

Yes, your code is fine. Something like this will be included into the next release.
