Hi;

I have to change the sorting algorithm used for all text items in any report control of my application. So I checked the code and found out that best would be to overwrite the virtual CXTPReportRecords::Compare() function. But I can't find any way to use my own CXTPReportRecords collection like in CreateGroupRow()...
What is the meaning of virtual functions when I can't derive?

All I want to achieve is, that the control should use locale setting when comparing strings!
I don't want to derive any item class - thats too boring.

Any help or hint is very welcome.

Any news regarding my question?
Can I solve it with 18.6 or higher?

I have been using CXTPReportControl::SetRowsCompareFunc() to do my row comparisons, with code like this for locale use:
bool operator()(const CBroker& b1, const CBroker& b2)
{
	std::locale::global(std::locale(""));  // (*)
	std::cout.imbue(std::locale());
	auto& f = std::use_facet<std::ctype<char>>(std::locale());

	std::string s1(b1.m_sName);
	std::string s2(b2.m_sName);

	f.tolower(&s1[0], &s1[0] + s1.length());
	f.tolower(&s2[0], &s2[0] + s2.length());
	return (s1.compare(s2) <= 0);
}


Does that meet your needs, or have I misunderstood your question?
