C# - Get ListView Visible Items?
Jun 25, 2012I have a ListView which might contains a lot of items, so it is virtualized and recycling items. It does not use sort. I need to refresh some value display, but when there are too many items, it is too slow to update everything, so I would like to refresh only the visible items.How could I get a list of all currently displayed items ? I tried to look into the ListView or in the ScrollViewer, but I still have no idea... the solution must NOT go throught all items to test if they can be seen, because this would be too slow.I'm not sure code or xaml would be usefull, it is just a Virtualized/Recycling ListView with its ItemSource bound to an Array.

Sorting A Listview Which Is Not Visible
Mar 26, 2009I use a listview control which is created at runtime because I don't need it visible to the user. I basically use it to store some information about paths, sort it and then pick out the data I need. It works very well apart from it doesn't seem to sort. For efficiency, I turn off sorting on the listview while the data is being added then enable sorting on the listview at the end. However, the sorting doesn't work. Is this because the listview isn't visible or am I just being daft?
View 18 RepliesEdit Item Or Subitem Values Of A Selected Listview Item?
May 19, 2009Ok, so I have a listview on one form, and when a button is pressed it opens up a new form with the contents of the selected listview item and it's subitems in a series of textboxes. The user can then change the data in the textboxes and either press save to make the changes or cancel to close the window. What command would I use to change the selected listview item and subitems to whatever is in the boxes?
this is the code that populates the boxes:
Private Sub Form_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim appeditcontents As String = main.passlist.SelectedItems(0).ToString

DoDragDrop List View Item Reordering - User Can Drag Media Tracks From One Listview To Another Listview
Feb 12, 2010I have a media browser program I am building. I am trying to use drag/drop so a user can drag media tracks from one listview to another listview and then use the second list view as a playlist in windows media player com object. Reading at MSDN I have found out that there is no built in support for item re-ordering with the listview control. I have listview1 working correctly but when I try to reorder items in listview2, the dragged item ends up at the end of the list. So basically I need to get the item insertion index corrected. I have tried more than 10 times to get this code right.
Here is my code which includes a form with two listview's.
Public Class Form1
Private Sub ListView_ItemDrag(ByVal sender As Object, ByVal e As _
System.Windows.Forms.ItemDragEventArgs) Handles ListView1.ItemDrag, _
ListView2.ItemDrag

Big Panel Visible And Not Visible Based On Selections Made By User
Jan 28, 2009I've got a panel - that's in a group box. All of this - with lots of other textboxes on labels - is in another panel (the big panel).I make the big panel visible and not visible based on selections made by the user.This small panel - that's in the group box. I cannot seem to make it appear.Even if I leave it VISIBLE at design time - the objects in it will not appear.Is there some kind of nesting problem that I'm not aware of!
View 9 RepliesJumping Between Forms - Making A Form Visible And Not Visible
Jul 17, 2009I'm having an odd problem when making a form visible and not visible and it not continuing to function. Here is what I have happening. I have a main form (frmMain) that is an MDIParent. On this form I have a menu to open a second form (frmCalculate) and populate a listview from Items in the database.
As I click or select items in the listview on frmCalculate the tag is read and data is pulled based on the id stored in that tag and fills in various fields on the form. This works great. However, I also have a context menu attached to the listview that allows me to perform a "what if" scenerio on the items I am calculating. When I select this menu, I hide the frmCalculate and open the frmWhatIf form where I can mess around with values on the item I had hilighted in the listview on frmCalculate. Nothing is pulled from or written back to the database here, all the information is filled in from fields on frmCalculate. It just allows me to look at rising costs and how they will affect my margins.... anyway.
If I then close frmWhatIf, it brings my frmCalculate back by setting its visible propery to true (never closed frmCalculate, just hid it). At this point if I click an item in the listview I get an exception for a null reference. IF however I never hide frmCalculate, I can open and close frmWhatIF without ever having an issue. Why do I lose the functionality to select items just by hiding and unhiding the form? As a test I added two menus to the toolbar on frmMain one called hide and one called show. I then opened frmCalculate with original menu item to populate the listview and selected a few items to test that it was working and then using the hide menu I made the form invisible and the show button to bring it back. This yielded the same exception so without even opening frmWhatIf the problem still occurs.
Add An Item To A Listview?
Jul 30, 2009I've currently picked up a small project and they one who assigned me to it wants me to upgrade the app using .NET.Is there any way I could add an item to a listview when I'm not on the form containing it? In VB6, something like this would work.
'Code on Form2
Form1.ListView.ListItems.Add "Item Name"
but in VB .NET, the code below doesn't add anything to the listview. It doesn't return any errors too.
Form1.ListView.Items.Add "Item Name"
And another thing, why is it that when I close the Login form to launch the Main form, the Main form closes automatically? The code in sub main is
' shared sub main
Application.Run(New frmLogin())
Then when correct credentials are given to the form, I'll do this.
'login form
Dim frmMain as frmMain = new frmMain
frmMain.Show()
Me.Close()
I assume things are done a lot differently than VB6.

View 6 RepliesFlashing A Listview Item?
Jul 4, 2009Problem: I have a listview control that gets populated with devices that are offline and after so many failed attempts, it will begin to flash, alerting the user.The code I use currently works, but seems almost random. The first time an item is added, it flashes just fine. Once a second device gets added, both items will stop blinking. A third item being added causes only the 3rd item to blink (first 2 still not blinking).
Here is the code I am using.Question 1: Why is this behavior like this?Question 2: is there a better way to have a list item "flash"?*After so many failed attempts, it triggers a timer to start, and in the tick event is this code*
