In ListView, how to select only the subitem, instead of selecting the whole row

[rajeshwaran]

I have tried, many style combinations, but, I could not able to select the individual subitems in ListView.

However, I can able to select the first column, but I cant able to select other columns.

Post a short demo script of the last thing you tried and maybe we can tweak it to work as you want.

P.S. Don't double post.

get selected item from column 1

_GUICtrlListView_GetItemText(GUICtrlGetHandle($ListView1),_GUICtrlListView_GetSelectedIndices($ListView1),0)

column1= 0 (<=index Number must be)

column2 =1 (<=index Number must be)

Index=n1-1

where n1 -eq to column number.

So lets say if you want to get selected item from column 2 :

_GUICtrlListView_GetItemText(GUICtrlGetHandle($ListView1),_GUICtrlListView_GetSelectedIndices($ListView1),1)

and etc.

Also i agree with PsaltyDS .

Without your script it`s enough hard to know where is your mistakes.

Please note that in future.

Hi Fire,

I can't able to understand, I want to know the column index and subitem index, please find below my sample script.

Your demo is a little over-wrought. Here's a simpler one:

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

Global $hGUI = GUICreate("Test", 400, 400)
Global $idLV = GUICtrlCreateListView("Col_0|Col_1|Col_2|Col_3", 20, 20, 360, 360)
Global $hLV = GUICtrlGetHandle($idLV)
For $n = 0 To 3
    GUICtrlCreateListViewItem($n & "_0|" & $n & "_1|" & $n & "_2|" & $n & "_3", $idLV)
Next
GUISetState()

GUIRegisterMsg($WM_NOTIFY, "_WM_NOTIFY")

Do
Until GUIGetMsg() = $GUI_EVENT_CLOSE

Func _WM_NOTIFY($hWnd, $iMsg, $wParam, $lParam)
    Local $tNMHDR = DllStructCreate($tagNMHDR, $lParam)
    Local $hWndFrom = HWnd(DllStructGetData($tNMHDR, "hWndFrom"))
    Local $iCode = DllStructGetData($tNMHDR, "Code")

    Switch $hWndFrom
        Case $hLV ; Came from the ListView
            Switch $iCode
                Case $NM_CLICK ; Is a CLICK message
                    Local $tLVInfo = DllStructCreate($tagNMITEMACTIVATE, $lparam)
                    ConsoleWrite("ListView Click:  hWndFrom = " & $hWndFrom & "; Index = " & _
                        DllStructGetData($tLVInfo, "Index") & "; SubItem = " & _
                        DllStructGetData($tLVInfo, "SubItem") & @LF)
            EndSwitch
    EndSwitch

    Return $GUI_RUNDEFMSG
EndFunc

When you catch a WM_NOTIFY message, you first see if it came from the control you are interested in, then see if the code matches the action you want (i.e. NM_CLICK). In the case of a ListView control, you then have to get the full NMITEMACTIVATE structure, which contains the index and subitem.
