Problem, I can not update data in GUICtrlCreateListView

[marcsusy]

Hello

I created a GUI with step GUICtrlCreateListView and values ​​from a database, when you step values ​​GUICtrlCreateListViewItem the first time works fine, but when I try to update the values ​​that have changed again with the same function GUICtrlCreateListViewItem values ​​are not updated still shows the previous, only works if I delete the window and return to create it, as I can do so without having to clear the main GUI.

Who can help me?

Take this example to get the basics down. Play with it first. Then, notice that as new items are added, the listview is automatically refreshed to reflect the current state.

You likely are doing something wrong in the updating from database to listview.

A small Eample how to edit an Item:

#include 
#include 

$hWndMain = GUICreate("List View Example", 420, 460)
$ListView = GUICtrlCreateListView("Col1|Col2|Col3", 2, 25, 416, 380)
$labelNumItems = GUICtrlCreateLabel("Number of items: ", 2, 2, 160, 20)
$btnEditItem = GUICtrlCreateButton("Edit an item", 20, 420, 380, 30)

For $i = 0 To 19
GUICtrlCreateListViewItem("Item " & $i & "|Col" & $i & ".1|Col " & $i & ".2", $ListView)
Next
_GUICtrlListView_SetColumnWidth($ListView,0,80)
_GUICtrlListView_SetColumnWidth($ListView,1,180)
_GUICtrlListView_SetColumnWidth($ListView,2,120)

$numItems = _GUICtrlListView_GetItemCount($ListView)
GUICtrlSetData($labelNumItems, "Number of items: " & $numItems)

GUISetState(@SW_SHOW, $hWndMain)
While 1
$msg = GUIGetMsg()
Switch ($msg)
Case $GUI_EVENT_CLOSE
Exit
Case $btnEditItem
$aItemsSelected = _GUICtrlListView_GetSelectedIndices($ListView,True)
_GUICtrlListView_SetItem($ListView,"Edited Item" & $aItemsSelected[1],$aItemsSelected[1])
_GUICtrlListView_SetItem($ListView,"Edited Col " & $aItemsSelected[1]& ".1",$aItemsSelected[1],1)
_GUICtrlListView_SetItem($ListView,"Edited Col " & $aItemsSelected[1]& ".2",$aItemsSelected[1],2)
EndSwitch
WEnd
