Hello!

I have a question about cancelling grag in XTP_NM_REPORT_DROP handler.

void CClass::OnReportItemDrop(NMHDR* pNMHDR, LRESULT* pResult)
{
    *pResult = 0;
    XTP_NM_REPORTDRAGDROP* pItemNotify = (XTP_NM_REPORTDRAGDROP*)pNMHDR;

    if(pItemNotify->pRecords->GetCount())
    {
            pItemNotify->pRecords->RemoveAt(0); // not working because of ASSERT(!m_bArray) in xtpreportrecord.cpp
    }
//but next is working and prevent all items from being dragged
    pItemNotify->pRecords->RemoveAll();

}

And the question is: can i cancel drag of certain items?
Thanks!
