Hi,

just a short question. 
I 've got a lisitview with a few columns and I want to register a different sort for two kinds of columns.
I 've got a solution, but I don't think it is a good one. 

Example : 
Col A = Names (Strings)
Col B = Age (Integers)

Right now I'm doing this:
1. _GUICtrlListView_RegisterSortCallBack
2. In my WM_NOTIFY 

Case GUICtrlGetHandle($search_LV)
            Switch $iCode
                Case $LVN_COLUMNCLICK ; A column was clicked
                    Local $tInfo = DllStructCreate($tagNMLISTVIEW, $iLparam)
                    ; Kick off the sort callback
;~                  ConsoleWrite('SEARCH_LV Column geklickt' & @LF)
                    ConsoleWrite("Sort: " & DllStructGetData($tInfo, 'SubItem'))
                    If $ColumnSorted <> DllStructGetData($tInfo, 'SubItem') Then
                        _GUICtrlListView_UnRegisterSortCallBack($search_LV)
                        ConsoleWrite('NEU' & @CRLF)
                    EndIf
                    $ColumnSorted = DllStructGetData($tInfo, 'SubItem')
                    If DllStructGetData($tInfo, 'SubItem') = 9 Or DllStructGetData($tInfo, 'SubItem') = 10 Then
                        ConsoleWrite('True: ' & _GUICtrlListView_RegisterSortCallBack($search_LV, True) & @CRLF)
                    Else
                        ConsoleWrite('False ' & _GUICtrlListView_RegisterSortCallBack($search_LV, False) & @CRLF)
                    EndIf
                    _GUICtrlListView_SortItems($search_LV, DllStructGetData($tInfo, 'SubItem'))

So, I store the column clicked in a global variable. If the column is clicked again (sort asc or desc) then all is fine, if another column then the one before is clicked, I unregister the callback and create a new one.

The new callback (in the if) depends on the column clicked because of the content to sort (strings or numbers).

Is there an easier / better way?

Do I have to use my own sorting function with GuiCtrlRegisterListViewSort?

Edit: It still doesn't work in every case (just noticed).

Thanks

Okay, maybe it is a little bit different to understand what I want.

Here is an example script.

Whats needs to be changed to get all comlums sortable correctly (literal,numeric and asc,desc)?

#include <ListViewConstants.au3>
#include <WindowsConstants.au3>
#include <GuiConstantsEx.au3>

I don't what the problem is with this question, but maybe many people think: "oh, it is an MVP who asked, then it has to be a very difficult question."

Anyhow, I found a solution but wasn't able to figure out how to do it with the RegisterCallBack funtion.

Here ist what I have so far (Still missing are the little arrows in the column  header, but I think I can handle that later)

#include <GuiListView.au3>
#include <ListViewConstants.au3>
#include <WindowsConstants.au3>
#include <GuiConstantsEx.au3>
#include <StructureConstants.au3>
#include <GUIConstantsEx.au3>

$search_LV = GUICtrlCreateListView("String|Number|String", 2, 2, 394, 268)
GUICtrlRegisterListViewSort(-1, "LVSort") ; Register the function "SortLV" for the sorting callback
GUICtrlSendMsg($search_LV, $LVM_SETEXTENDEDLISTVIEWSTYLE, $LVS_EX_GRIDLINES, $LVS_EX_GRIDLINES)
GUICtrlSendMsg($search_LV, $LVM_SETEXTENDEDLISTVIEWSTYLE, $LVS_EX_FULLROWSELECT, $LVS_EX_FULLROWSELECT)
GUICtrlCreateListViewItem("line4|5|1A", $search_LV)

    Local $sItemText = DllStructGetData($tBuffer, 1)

    Return $sItemText
EndFunc   ;==>GetSubItemText

If somebody has an exmaple how to sort two columns differently with UDF_Callback_functions or at least shows the concept how to do, I'm still interested. THANKS!

You should not unregister/register the sort function after every sort. Only when you sort by another column.

This is the code in post 2:

#include <GuiListView.au3>
#include <ListViewConstants.au3>
#include <WindowsConstants.au3>
#include <GuiConstantsEx.au3>
#include <StructureConstants.au3>

Opt('MustDeclareVars', 1)

Global $search_LV, $B_DESCENDING
GUICreate("ListView Sort by Column Click", 400, 300)
$search_LV = GUICtrlCreateListView("String|Number|String", 2, 2, 394, 268)
GUICtrlSendMsg($search_LV, $LVM_SETEXTENDEDLISTVIEWSTYLE, $LVS_EX_GRIDLINES, $LVS_EX_GRIDLINES)
GUICtrlSendMsg($search_LV, $LVM_SETEXTENDEDLISTVIEWSTYLE, $LVS_EX_FULLROWSELECT, $LVS_EX_FULLROWSELECT)
GUICtrlCreateListViewItem("line4|5|1A", $search_LV)
GUICtrlCreateListViewItem("line5|4.50 |1B", $search_LV)
GUICtrlCreateListViewItem("line5|4.0 |2C", $search_LV)
GUICtrlCreateListViewItem("line3|23|01", $search_LV)
