Hoi

Is it possible in a treeview to expand all parent but not the childeren?

If I use "_GUICtrlTreeView_Expand" than it will expand all childeren as well.

Thanks!

It will probably take a function with your own logic.  Here are the funcs I would use to accomplish this:
 

_GUICtrlTreeView_SetState ( $hWnd, $hItem [, $iState = 0 [, $bSetState = 0]] )
_GUICtrlTreeView_IsParent ( $hWnd, $hParent, $hItem )
_GUICtrlTreeView_Level ( $hWnd, $hItem )
_GUICtrlTreeView_GetNextSibling ( $hWnd, $hItem )

Thank for your anwser but I don't have a clue how to implement this?

Ok, I'll do what I can to help.  Can you explain in more detail the behavior you want?  Do you have a script/example with treeview in it to work with?

What is the structure of the tree?  Is there a single root or are there multiple parents at the root.  
How about a picture?

Also, this command/func will allow you to expand a single item.
 

_SendMessage(GUICtrlGetHandle($idTreeView), $TVM_EXPAND, $TVE_EXPAND, $hItem, 0, "wparam", "handle")

It took some time but here I have a sample program.

I've tryd your line of code above (_sendmessage) but no luck.

#include <GuiTreeView.au3>
#include <GUIConstantsEx.au3>
#include <WindowsConstants.au3>

Local $SP_array[11], $C_array[11]

$gui = GUICreate("Gui", 500, 465, -1, -1, -1);, $WS_EX_TOPMOST)
$gui_treeView = GUICtrlCreateTreeView(10, 10, 480, 280, BitOr($TVS_HASBUTTONS, $TVS_DISABLEDRAGDROP, $TVS_HASLINES, $TVS_HASLINES, $TVS_SHOWSELALWAYS, $TVS_CHECKBOXES, $TVS_LINESATROOT))

$C_head_item = GUICtrlCreateTreeViewItem("Parent 1", $gui_treeView)
$SP_head_item = GUICtrlCreateTreeViewItem("Parent 2", $gui_treeView)

Local $SP_child = GUICtrlCreateTreeViewItem("Child", $SP_head_item)
Local $C_child = GUICtrlCreateTreeViewItem("Child", $C_head_item)

For $i=0 To 10
    $SP_array[$i] = GUICtrlCreateTreeViewItem($i, $SP_child)
    $C_array[$i] = GUICtrlCreateTreeViewItem($i, $C_child)
Next

GUISetState()

While 1
    Switch GUIGetMsg()
        Case $GUI_EVENT_CLOSE
            Exit
    EndSwitch
    Sleep(20)
WEnd

I want it to expand the Parent but not futher,  See the screen shot below.

I Hoop you have a idea how to do that.

nend,

Just loop through the top level items of the TreeView and send the message to each one found:

#include <GUIConstantsEx.au3>
#include <WindowsConstants.au3>
#include <GuiTreeView.au3>

Local $SP_array[11], $C_array[11]

$gui = GUICreate("Gui", 500, 465, -1, -1, -1);, $WS_EX_TOPMOST)
$gui_treeView = GUICtrlCreateTreeView(10, 10, 480, 280, BitOr($TVS_HASBUTTONS, $TVS_DISABLEDRAGDROP, $TVS_HASLINES, $TVS_HASLINES, $TVS_SHOWSELALWAYS, $TVS_CHECKBOXES, $TVS_LINESATROOT))

$C_head_item = GUICtrlCreateTreeViewItem("Parent 1", $gui_treeView)
$SP_head_item = GUICtrlCreateTreeViewItem("Parent 2", $gui_treeView)

Local $SP_child = GUICtrlCreateTreeViewItem("Child", $SP_head_item)
Local $C_child = GUICtrlCreateTreeViewItem("Child", $C_head_item)

For $i=0 To 10
    $SP_array[$i] = GUICtrlCreateTreeViewItem($i, $SP_child)
    $C_array[$i] = GUICtrlCreateTreeViewItem($i, $C_child)
Next

GUISetState()

$hItem = _GUICtrlTreeView_GetFirstItem($gui_treeView)
Do
    _SendMessage(GUICtrlGetHandle($gui_treeView), $TVM_EXPAND, $TVE_EXPAND, $hItem, 0, "wparam", "handle")
    $hItem = _GUICtrlTreeView_GetNextSibling($gui_treeView, $hItem)
Until $hItem = 0


While 1
    Switch GUIGetMsg()
        Case $GUI_EVENT_CLOSE
            Exit
    EndSwitch
WEnd

And note you do not need a Sleep in a GUIGetMsg loop - as explained in the help file, the function has an automatic pause incorporated so as not to hog the CPU.

You make it look so simple ;-) Thanks for the help!

And the pause in a loop is something I didnt know that the software allready take care of that, every day I learn something new.

You are certainly not alone in that.....

But when you reply, please use the "Reply to this topic" button at the top of the thread or the "Reply to this topic" editor at the bottom rather than the "Quote" button - responders know what they wrote and it just pads the thread unnecessarily.
