Drag & drop with virtual records

Hi all, 

What's the trick handling drag & drop in a grid control having virtual records? I have added response handler for XTP_NM_GRID_BEGINDRAG but since I have virtual records I get the pointer to the same record regardless which one I drag. I could potentially use GetSelectedRows, but thought I should have the information needed in the XTP_NM_GRIDDRAGDROP structure.

Second question, is it possible to prevent the start of a drag operation when responding to XTP_NM_GRIDDRAGDROP ? I have tried setting different values on *pResult and pItemNotify->bReturnValue.

Third question: I tried to use XTP_NM_GRID_HASVALIDDROPTYPE message to change dropEffect, however, this is ignored in DROPEFFECT CXTPGridControl::OnDragOver? 

XTP_NM_GRIDDRAGDROP nmData; nmData.dropEffect  = dropEffect; nmData.pDataObject = pDataObject; nmData.pt    = point; // R-DD << nmData.dwKeyState = dwKeyState; // R-DD >> int iValid = (int)SendNotifyMessage(XTP_NM_GRID_HASVALIDDROPTYPE, (NMHDR*)&nmData); m_nOLEDropAbove = nmData.bAbove; if ((dropEffect != DROPEFFECT_NONE) // <- Shouldn't this be nmData.dropEffect? && (!pDataObject || (!pDataObject->IsDataAvailable(m_cfGrid) && iValid != 1))) dropEffect = DROPEFFECT_NONE;
