The Preview-Modus in ReportControl does not work since 18.4.0!
See ReportSample

Hello,

Sorry I have confused ReportRecordItemPreview with PrintPreview where we have made some improvements.

So I found reason of empty ReportRecordItemPreview. Bug in method CXTPReportRecordItemPreview::OnDrawCaption() and the same copy-past bug in GetCaptionRect() method  
void CXTPReportRecordItemPreview::GetCaptionRect(XTP_REPORTRECORDITEM_ARGS* pDrawArgs, CRect& rcItem)
{
    ASSERT(NULL != pDrawArgs);
    ASSERT(NULL != pDrawArgs->pControl);

    if (NULL == pDrawArgs->pControl)
        return;

    CRect& rcIndent = pDrawArgs->pControl->GetPaintManager()->m_rcPreviewIndent;
    rcItem.DeflateRect(rcIndent.left - XTP_DPI_X(2), -XTP_DPI_Y(1), rcIndent.right, -rcIndent.bottom);
}

void CXTPReportRecordItemPreview::OnDrawCaption(
    XTP_REPORTRECORDITEM_DRAWARGS *pDrawArgs,
    XTP_REPORTRECORDITEM_METRICS  *pMetrics)
{
    ASSERT(NULL != pDrawArgs);
    ASSERT(NULL != pDrawArgs->pControl);

    if (NULL == pDrawArgs->pControl)
        return;
......
Regards,

Hello Muckl,

This can be solved only by changing c++ core. Codejock has SuitePro with source code bundle, ask in sales.

Also you can use previos version of ReportControl.

I had the same problem today and struggled to find out why. It wasn't until I found this post that I realized that there is a bug in v18.4.0 of the toolkit.

However I managed to workaround the problem by inheriting from CXTPReportRecordItemPreview and overriding the OnDrawCaption method.
