Hi,

I'm having a problem of implementing a custom sorting (by date) for CXTListCtrl. I overrided the 'SortList' function in my derived class. But somehow this function is not called when the list header column is clicked (it still conducts the default text sorting). Could you show me an example how I can do this? I'm using Toolkit Pro 9.51.

Thanks in advance,

Best regards,

JLee 

Hello,

Show your code. Did you try to trace?

Hi oleg,

Thanks for your response. I did trace into the part of my code.

The attached is a project I modified directly from the original ListCtrl sample code of Toolkit Pro 9.51. I added a derived class 'CMySortListCtrl', in which I overrided the virtual function 'SortList' (its code I directly copy and pasted from CXTShellListBase::SortList). Then I changed the declaration of the member variable 'm_listCtrl' in 'CListCtrlDlg' to 'CMySortListCtrl'. The project was compiled in VS7.0.

(I think I may find the problem now. It tends out that the 'SortColumn' gets notified for sorting when the list header is clicked in the sample. The overrided 'SortList' function is not called. Is this the way it is supposed to work?)

Thanks again,

JLee

in ListCtrlDlg.h replace

CXTtHeaderCtrl m_header;

to

CXTFlatHeaderCtrl m_header;
