I have a list of movie names in a list view. The user clicks a button and the posters and names are displayed instead. I want to be able to change it back to the list again. The problem I am facing is the size of the rows stay the same as the pictures when there not even there, the text alignment isnt fully to the left either. Is there a way to return the listview to its original state?

I'm trying to call a function from a sub, and have it return an array to the original sub.
I currently have:
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Call Registry_GetUsers()
End Sub
[code]....
Which works, but I want to loop through each of the items in users from within the original sub, not the function, as it currently does.So I need to return the array to the original sub, so I can then iterate through it from there.
I'm trying to make a form that when it is return to, it will have the same state for the controlsI have 3 .net pages, testa,testb,testctesta, sets up the session and has a button to go to testb. testb has a check box and a button to go to testc. testc has a button to return to page testb.I want it so when we leave testc, and then come back the check mark will be in the same state, but it is not. it stays as uncheck when I go from page testc back to page testbThis is what i did,On the page load event, I set the check box equal to the "button" Session variable. On the button event I save the button checked state in the Session variable and call page testc
Protected Sub Button1_Click(sender As Object, e As System.EventArgs) Handles Button1.Click
Server.Transfer("testb.aspx")
End Sub

Assume you have controls A, B, C, D and E all with a Visibility property. You also have states 1,2,3,4,5 and 6 in which various combinations of your controls would be displayed. Currently this is being handled by switch statements for each state: i.e.
Select Case PageState
case "1"
a.visible = false
b.visible = true
[code]....
As you can imagine, this becomes a pain as every state needs a show/hide statement for each control. How can I refactor this so that adding controls and/or states becomes trivial?My first instinct is to extend the control and add a collection of states that it should display for but this sounds like overkill.
Edit:I was deliberately vague in my question in case this has other implications. In my current instance the "controls" in question are ASP Panels. Does that change anything?

I'm kicking my self for not being able to resolve this.I have a few items in my context menu thats for my listbox that toggle enable/disable depending on eitheritem is selecteditem is checked.the top 3 items should be enabled only if a item is selected, which works,and the bottom 2 only if an item is checked in the list.(it is a chked list)But what i would really like is that if ONE checkbox is checked then the top three would be disabled. i did try adding a for loop to check for an item is checked but it only half the time worked. (i added the code also)
vb
''' <summary>
''' Ensures the process manager context menu items reflect the selection/checked

I have managed to get it to write a string to a textfile if the listviews checkbox is checked but i can not get it to write a particular string if it is unchecked.

How do i Iterate an unchecked item as the library doesn't have .UnCheckItems?
If its checked i need to add "true" to the string and if its unchecked i need to add "false" to a string that gets written to a textfile.

This all works fine, but i have no idea how to reload this information when the form loads.Obviously it needs to read the string, the seperate the username and password.also is it possible to password char the password section in the listview? at the moment it can be read.

I have a ListView capable of displaying files in all available views (Large Icon, Small Icon, Tile, List, Details). Now I am wondering how to properly use the SmallImagelist and LargeImagelist for the small and large icons...the ListView is actually a modified listview (inheriting from ListView), using a modified ListViewItemCollection.In this custom ListViewItemCollection I use the Add override function to add a few details to my ListViewItem:
vb.net Public Overrides Function Add(ByVal value As System.Windows.Forms.ListViewItem) As System.Windows.Forms.ListViewItem
Dim file As clsTexture = TryCast(value, clsTexture)
If file IsNot Nothing Then
[Code]...
I realize it is a pretty complex post to read and will probably not get very many answers, but I really want to make the most of my Listviews...Of course, one work around is to just always use the LargeIcon which then gets scaled down automatically when the SmallImagelist is used but I am pretty sure there are icons that are very different in Large or Small view...
Well, just struggeling to decice on which would suit my situation best. I am developing a simple app to show a log of radio messages. Should I display these in a listview or in a datagridview? What is the actual difference?
View 2 RepliesI have a Callback from a socket that get called each time I get a Packet, It then add an IP address to a Listview. Now I got all the IP with the Active Connections, I cannot, From the call back check if the IP is already added to the list so I made a class and a Delegate and used UI.Invoke to call the method and check if Duplacates then add the coordinating information, I went a Step further and did a lookup on host name to pull the computer hostname from the ipaddress, But I do it each time due to getting Multiple of the same IP and I do not want to do it on the thread that the UI.INvokes from due to resolving a Host name will lock the GUI for a full Second, so you can imagine doing this on a network with constant information.
Now what I want is from the Async thread that is receiving all the data to Invoke the UI thread, check if ListviewItem already exist then exit the Dispatched Sub, then from the Async thread again check the Classes return value then if it dose not already exist start the lookup, I have this so far but Im not 100% sure if it is working the right way, Is Invoke Async or Sync even though Im telling another thread to start, if now how can I made My Async thread wait on UI.Invoke to complete 100% so I can check the classes return value?
