Subject: catch filter edit control from Report Control

I would like to intercept when the filter edit control has been changed in order to display a "# results found" message;

I think I can find easily how to retrieve the number of items displayed in the report control;

But how can I know this is related to the filter applied ?

Use BOOL CXTPReportFilterEditControl::OnChange()

Thanks; I suppose the only way to make additional features is to derivate a new class from CXTPReportFilterEditControl ?

I would like to intercept the filter change in order to reflect the number of elements found (i.e. Internet Explorer 8 search bar) but I also found that the interesting property CXTPReportControl::m_nPopulatedRecordsCount is "protected" as well;

Is there a turn-around to avoid having to derivate both classes ??

CXTPReportFilterEditControl m_wndFilterEdit belong to your CXTPReportView derived class or smth similar (dialog?).

You can create it (suppose with IDC_FILTER_EDIT as ID) or subclassed it

if (m_wndFilterEdit.GetSafeHwnd() == NULL) {

m_wndFilterEdit.SubclassDlgItem(IDC_FILTER_EDIT, &pWnd->m_wndFilterEdit);

GetReportCtrl().GetColumns()->GetReportHeader()->SetFilterEditCtrl(&m_wndFilterEdit); }

and can use notification e.g. ON_EN_CHANGE(IDC_FILTER_EDIT, You function)

ok, I can intercept the notification message from either dialogbar or reportview, thankx.

but I still can't get the number of report items listed once the filter has been applied...

how can I access to CXTPReportControl::m_nPopulatedRecordsCount ? or how can I recalculate it ?

thankx ;)

E.g. keep on app level prev record count and compare with new value after filter applied

Thanks! here's what I did when handling the ON_EN_CHANGE:

Get the number of items actually displayed : GetReportCtrl().GetRows()->GetCount();

Is it a good way to proceed, I mean, this function will always return the number of items displayed with or with no filter applied.

Note: maybe you should consider giving direct access to CXTPReportControl::m_nPopulatedRecordsCount in next release ?

One more consideration about : GetReportCtrl().GetRows()->GetCount()

This code returns the number of rows currently displayed in the report control; BUT it includes all the group rows at the same time.

What is the way to either

- calculate items displayed (not just visible) without counting group rows

- calculate only number of group rows (so I can then substract with previous value)

Thanks !!

Use BOOL CXTPReportRow::IsGroupRow();
