Hi.

I have a CXTPListCtrl with dates in a column. To sort this data correctly I need to do a custom sort routine. In the documentation I have found CXTPListBase::SortList Method, but there is no explanation about it.

Can anyone give me an example about using it ?

Thanks.

Hi!

Can you sort the items before adding them to the list?

Thanks, but I can't sort before because I have multiple columns, and the user can select what to sort.

I'm testing CXTPListCtrl::SortList()... It's called when the user clicks in a column... Ok.

I'm triying to sort columns using MoveRow() in the function, but doen't work. The rows are sorted by default no matter what I write on the function.

Please do a better documentation...

Form Help:

Override this member function in your derived class to perform custom sort routines.

How ????

Hello,

You can explore method CXTPShellListBase::SortList

CXTPShellListBase is derived from CXTPListBase.

Hi,
Codejock used the sort mechanism from CListCtrl:
...
m_pListCtrl->SortItems(
ListViewCompareProc, (nCol + 1)*(bAscending? 1: -1));
...
so you need a own Callback function like:
static int CALLBACK MyCompareProc(LPARAM lparam1, LPARAM lparam2, LPARAM lparamSort);

here is an example:

I hope this helps!

Thanks for the help...

I was using other example: http://www.codeproject.com/Articles/27774/CListCtrl-and-sorting-rows

The example works with a standar control, but if I use a derived class of CXTPListCtrl no matter what I do, always is sorted by default.

My callbackfunction returns rand ()%2, and all is sorted !!!

Can be a bug ????
