Multiple Combobox Problem, how to convert onhover to on click ?

[autoitaddicted]

I'm using the code below for choosing city and then choosing district but i realized that even i didn't choose anything it still changes combo boxes, considering it will connected to a online sql db, it can be blocked easily because of sending too much requests. So, how can i fix that code i need a combo-box affects other combo-box only when i clicked on it not just mouse hover..

any help will be appreciated

#include <GUIConstantsEx.au3>
#include <GuiListView.au3>
GUICreate("My GUI combo",250,150)
$_Combo_Ilce =GUICtrlCreateCombo("İlçe Seçiniz", 10, 10, 200)
For $n = 1 To 10
    GUICtrlSetData($_Combo_Ilce, "İlçe " & $n)
Next
$_Button = GUICtrlCreateButton ( 'Select', 20, 70 )
GUISetState()
$_ReadOld=''
$_Combo_Mahalle = GUICtrlCreateCombo("Mahalle Seçiniz", 10, 50, 200)
While 1
    $msg = GUIGetMsg()
    Switch $msg
        Case $GUI_EVENT_CLOSE
            ExitLoop
        Case $_Button
            ConsoleWrite ( "+->-- Select : " & GUICtrlRead ( $_Combo_Ilce ) & @Crlf )
    EndSwitch
    $_Read = GUICtrlRead ( $_Combo_Ilce )
    If $_Read <> $_ReadOld and $_Read<>"İlçe Seçiniz" Then
  GUICtrlSetData($_Combo_Mahalle, "","")
  GUICtrlSetData($_Combo_Mahalle,"Mahalle Seçiniz","Mahalle Seçiniz")
  For $n = 1 To 10
  GUICtrlSetData($_Combo_Mahalle, &$_Read " Mahalle " & $n)
  Next
        ConsoleWrite ( "-->-- $_Read : " & $_Read & @Crlf )
        $_ReadOld = $_Read
    EndIf
WEnd
