Reload ListView colums

7 posts in this topic

Hi!

I have a GUI with a empty listview what I need to do is to "reload" the list view with the new data.

The data with I'm filling it, are from a DB query so the listview columns could be different, sometimes could be five cols sometimes could be ten, and so on...

So this is my problem I have 2 tabs, in the first is the listview empty, for example if a do a query that return 2 cols, name and brand I need to display the data in the listview with the two columns with their names, an the data of each column, and if then I do a query that return 7 columns i want to display in the same listview the new 7 columns that could be different from the firs two, and if I do a query that return 5 col I need to reload the listview with the five columns.

If a create a listview with two cols and then try to display the new data with more cols the listview only display the first two cols, or if I create a listview with ten cols and then I try to display a new query with five cols, the other five cols remain in the list view.

In a few words, I want to adjust the listview with the exact number columns returned by the query and replace the old data with the new one and replace the column names.

Thanks in advance!

This is a plain example of what I need

#Include <GuiListView.au3>
#include <ButtonConstants.au3>
#include <EditConstants.au3>
#include <GUIConstantsEx.au3>
#include <ListViewConstants.au3>
#include <TabConstants.au3>
#include <WindowsConstants.au3>
$Form1_1 = GUICreate("Form1", 629, 447, 192, 124)
$Tab1 = GUICtrlCreateTab(16, 24, 553, 409)
GUICtrlSetResizing(-1, $GUI_DOCKWIDTH+$GUI_DOCKHEIGHT)
$TabSheet1 = GUICtrlCreateTabItem("TabSheet1")
$ListView1 = GUICtrlCreateListView("||", 48, 136, 441, 289)
GUICtrlSetFont(-1, 8, 400, 0, "Arial")
$Input1 = GUICtrlCreateInput("Input1", 48, 56, 121, 22)
GUICtrlSetFont(-1, 8, 400, 0, "Arial")
$Button1 = GUICtrlCreateButton("Button1", 180, 51, 75, 25, $WS_GROUP)
GUICtrlSetFont(-1, 8, 400, 0, "Arial")
$Button2 = GUICtrlCreateButton("Button2", 456, 95, 75, 25, $WS_GROUP)
$TabSheet2 = GUICtrlCreateTabItem("TabSheet2")
GUICtrlCreateTabItem("")
GUISetState(@SW_SHOW)
#EndRegion ### END Koda GUI section ###
 
 
While 1
$nMsg = GUIGetMsg()
Switch $nMsg
  Case $GUI_EVENT_CLOSE
   Exit
  Case $Button1
   _button1()
  Case $Button2
   _button2()
EndSwitch
WEnd
Func _button1()
_GUICtrlListView_DeleteAllItems($ListView1)
;~  Here Adjust Columns
GUICtrlSetData($ListView1,"Col1|Col2")
GUICtrlCreateListViewItem("l1c1|l1c2", $ListView1)
EndFunc
Func _button2()
_GUICtrlListView_DeleteAllItems($ListView1)
;~  Here Adjust Columns
GUICtrlSetData($ListView1,"NewCol1|NewCol2|NewCol3|NewCol4")
GUICtrlCreateListViewItem("l1c1|l1c2|l1c3|l1c4", $ListView1)
EndFunc

I managed updating a listview like that:

I had an array variable which holds all my things for my list: $listdata[$X]

Than if i added something i used this lines:

$listthings = ""

For $X = 1 To $listdata[0]

If $X == $listdata[0] Then

$listthings = $listthings&$listdata[$X]

Else

$listthings = $listthings&"|"&$listdata[$X]

EndIf

Next

If i wanted to delete sth from the list, i just searched it in the array and removed this part, then renewed the list...

Thanks jWalker, but there's any function to automatically adjust the number of columns?

_GUICtrlListView_AddColumn and _GUICtrlListView_DeleteColumn would be the place to start.

If I posted any code, assume that code was written using the latest release version unless stated otherwise. Also, if it doesn't work on XP I can't help with that because I don't have access to XP, and I'm not going to.

Thanks for the responses.

I do what you suggest but can I destroy the ListView and create a new one just in the same tab? because when i destroy the Listview an try to create another this listview is displayed on every tab.

I think destroy and create a new one is faster than erase all data, delete columns and create the columns needed, or maybe is not the best way to do that...

If you want to have the Listview in thr right tab you will need to use GUISwitch before creating the listview to switch to the proper tab. There are examples of what you need to do to accomplish this. Search for GUISwitch in this forum.
