How do I pick up the action of the highlited row changing in a CXTPReportControl?

Basically, the equivelant of OnSelChange() for a CListBox?

Thanks,

Brad

Hi Brad,

There is an overridable method: virtual void CXTPReportControl::OnSelectionChanged()
which sends XTP_NM_REPORT_SELCHANGED notify message to an owner.

Also see XTPReportDefines.h for more report notifications.

I've got the following code in my program. OnReportItemClick works fine, and the pRow member is always the row at the index of the row clicked, but in the other handler, the pRow member is always the row from index zero, and thus, GetIndex() returns zero, instead of the correct index.

What am I doing wrong?

ON_NOTIFY(NM_CLICK, IDC_RPT, OnReportItemClick)
ON_NOTIFY(XTP_NM_REPORT_SELCHANGED, IDC_RPT, OnSelectionChanged)

void CUnicorMedDlg::OnReportItemClick(NMHDR * pNotifyStruct, LRESULT * /*result*/)
{
XTP_NM_REPORTRECORDITEM* pItemNotify = (XTP_NM_REPORTRECORDITEM*) pNotifyStruct;

if (pItemNotify->pRow)
int idx = pItemNotify->pRow->GetIndex();
}

void CUnicorMedDlg::OnSelectionChanged(NMHDR * pNotifyStruct, LRESULT * /*result*/)
{
XTP_NM_REPORTRECORDITEM* pItemNotify = (XTP_NM_REPORTRECORDITEM*) pNotifyStruct;

if (pItemNotify->pRow)
int idx = pItemNotify->pRow->GetIndex();
}

Yes, for the XTP_NM_REPORT_SELCHANGED message pNotifyStruct is NMHDR only.

You shouldn't convert it to XTP_NM_REPORTRECORDITEM.
Unfortunately, there is a mistake in documentation.

Multiple rows can be selected/unselected at one time and
the message with a single row index will not be sent.

You have to use CXTPReportControl::GetSelectedRows() method to retrieve a new selected rows collection.
