Hi. I am using a CXTPReportView which has a built-in CXTPReportControl.

The application I generated is automatically handling the cut/copy/paste functions and it cause me trouble.

For example, I would like to manage my own copy/cut text data format and use XML, which means I need to intercept the cut/copy/paste messages.

I would prefer to handle these message from the CXTPReportView rather and derivate the ReportControl class.

Any hint ?

Thanks!!

ReportPaneViewView.h

class CReportPaneViewView : public CXTPReportView

protected:

afx_msg void OnEditCut();

afx_msg void OnEditCopy();

afx_msg void OnEditPaste();

afx_msg void OnUpdateEditPaste(CCmdUI* pCmdUI);

afx_msg void OnUpdateEditCopy(CCmdUI* pCmdUI);

afx_msg void OnUpdateEditCut(CCmdUI* pCmdUI);

ReportPaneViewView.cpp

BEGIN_MESSAGE_MAP(CReportPaneViewView, CXTPReportView)

//{{AFX_MSG_MAP(CReportPaneViewView)

ON_COMMAND(ID_EDIT_CUT, OnEditCut)

ON_COMMAND(ID_EDIT_COPY, OnEditCopy)

ON_COMMAND(ID_EDIT_PASTE, OnEditPaste)

//}}AFX_MSG_MAP

END_MESSAGE_MAP()

void CReportPaneViewView::OnEditCut() { AfxMessageBox(_T("OnEditCut")); } .......

Thankx! It was the easiest way to do it

I didn't tried it as I thought the ReportControl would prevent from the CView messages;

On the same way, I would also need to intercept items dragged into the ReportControl in order to change some data on the fly;

Which message handled / function should I add and how to get the handles of dropped Report items ?

Thankx!

You can use your own class derived from CXTPReportControl and overwrite functions

virtual void OnBeginDrag(CPoint point);

virtual DROPEFFECT OnDragOver(COleDataObject* pDataObject, DWORD dwKeyState, CPoint point, int nState);

virtual BOOL OnDrop(COleDataObject* pDataObject, DROPEFFECT dropEffect, CPoint point);

you can also try the previous post way...

You mean by handling messages from the control (like NM_BEGINDRAG) from the ReportView ?

I am sure you can do this research yourself

Yep, sorry, that was an easy one, here's the answer for those who would be interested:

Add this handle in the ReportView (dont' forget include file declaration):

ON_NOTIFY(XTP_NM_REPORT_DROP, XTP_ID_REPORT_CONTROL, OnReportDrop)

Then this code:

void CReportSampleView::OnReportDrop(NMHDR * pNotifyStruct, LRESULT * /*result*/)
{
XTP_NM_REPORTDRAGDROP* pItemNotify = (XTP_NM_REPORTDRAGDROP*)pNotifyStruct;

ASSERT(pItemNotify->pRecords);

// in this example, we access to a derivated CXTPReportRecord class with a GetTitle function

CString strTitle;

      // handle each dropped record one after another
       for (int i=0; i<pItemNotify->pRecords->GetCount(); i++)
       {
            CMyDerivatedRecord* pRecord = ((CMyDerivatedRecord*)pItemNotify->pRecords->GetAt(i));

strTitle = (pRecord->GetAt(i))->GetTitle();

// do something, like for example change Title to avoid duplicates ;-)

ChangeTitleFunction(strTitle);

((CXTPReportRecordItemText*)pRecord->GetItem(IDX_TITLE))->SetValue(strTitle);
}
}

This example should work for any other DragnDrop notification messages;

BOOL CXTPReportPaintManager::m_bForceShowDropMarker; // TRUE if Force Show Drop Marker

//used to support external (OLE) drag & drop handler and take care of drop marker line drawing and auto-scrolling
