I wanted to use the same CReportMultilinePaintManager class used in the reportcontrol sample , here is the code :

int CReportMultilinePaintManager::GetRowHeight(CDC* pDC, CXTPReportRow* pRow)

{

if (pRow->IsGroupRow() || !pRow->IsItemsVisible())

return CXTPReportPaintManager::GetRowHeight(pDC, pRow);

CXTPReportColumns* pColumns = pRow->GetControl()->GetColumns();

int nColumnCount = pColumns->GetCount();

XTP_REPORTRECORDITEM_DRAWARGS drawArgs;

drawArgs.pControl = pRow->GetControl();

drawArgs.pDC = pDC;

drawArgs.pRow = pRow;

int nHeight = 0;

for (int nColumn = 0; nColumn < nColumnCount; nColumn++)

{

CXTPReportColumn* pColumn = pColumns->GetAt(nColumn);

if (pColumn && pColumn->IsVisible())

{

CXTPReportRecordItem* pItem = pRow->GetRecord()->GetItem(pColumn);

drawArgs.pItem = pItem;

XTP_REPORTRECORDITEM_METRICS itemMetrics;

pRow->GetItemMetrics(&drawArgs, &itemMetrics);

CXTPFontDC fnt(pDC, itemMetrics.pFont);

CRect rcItem(0, 0, pColumn->GetWidth() - 4, 0);

pRow->ShiftTreeIndent(rcItem, pColumn);

pItem->GetCaptionRect(&drawArgs, rcItem);

pDC->DrawText(pItem->GetCaption(pColumn), rcItem, DT_WORDBREAK|DT_CALCRECT);

nHeight = max(nHeight, rcItem.Height());

}

return max(nHeight + 5, m_nRowHeight) + (IsGridVisible(FALSE)? 1: 0);

}

but when I added this class to my program , it seems that pItem->GetCaption(pColumn) always return an emptry string , and consequently GetRowHeight return 0 ,

is there another way to access my CXTPReportRecordItem and retreive the item text ?

When you do use Virtual records, do not forget that actual text for an item is set after calling GetItemMetrics(...) method . So far, changing pItem->GetCaption(pColumn) in this code to itemMetrics.strText should help.

hello sserge

thank you for the tip

, i have replaced pItem->GetCaption(pColumn)

with itemMetrics.strText , then you have to add the following code to make it working ,

you have to add :

drawArgs.pColumn = pColumn;

before you call :

pRow->GetItemMetrics(&drawArgs, &itemMetrics);

now it working fine , thanks again
