I am trying to programmatically select all items, including subitems, in a listview and can't seem to get the result I am looking for. I have FullRowSelect = True set and when I click on the items, all is fine. However, if I use the following code, only the ListViewItem is selected and not the item's subitems. Is there a way to achieve this?

This is the first time I have used a list view control since vb 6, and I have some basic questions.
1) How do I get the listview to show each item in a seperate row?
2) How do I add sub items to the listview?
Below is the code of the function I am working on to populate the listview. Right now it shows my entry in columns and I dont know how to display the sub items.
Private Sub loadListView()
Dim str As String
Dim SQLString As String
Dim k As Integer
str = ""

I have a listview with a few items like below. What I need is when I select an item in the listview then click a button it will go to the url that in the second column in a webbrowser.

View 2 RepliesI had a DataGridView, and already able to add DataGridViewComboBoxColumn to it. It read data from database StoredProcedure using custom ValueDescriptor class, this is the code for it:
Shared Sub fillComboBoxCellUsingSP(ByVal comboBox As DataGridViewComboBoxColumn, ByVal proc_name As String, ByVal param As Object(), ByVal firstitem As String)
Dim dt As New DataTable

Actually, the line that read comboBox.Value = o is okay. But still, the combo box cell didn't display the value. Just empty. And sometimes, DataError event raised.
I have a ListView box that has 3 columns. The first column is the Item and the next two columns are subitems if I understand correctly.
I can easily add items. How can I add 2 subitems to that one item.

For i As Integer = 0 To Me.lstdep.Items.Count - 1
If dt.Rows(0)(3).ToString.Trim = Me.lstdep.Items(i).ToString.Trim Then
lstdep.SetSelected(i, True)
End If
Next
running the above code i can select only a single item from the sql server 2005.But i want to select multiple items which are seperated by comma in the back end ....
There are very few examples out there for MS Chart and VS 2008 (the ones provided by MS are for a version different than what I have). What I am trying to do is get the value of the subitems in a listview (1 subitem is Subtotal and the other is Shipping) and put them on the chart. I don't know the best way to do this. I managed to get some code to work with a Datagridview but not with a listview. I have pasted the code for the chart with the datagridview below (to make the code run simply add MS Chart, a Datagridview and a button.Also, I posted a screen capture of a listview with the chart to give a better idea of what I am trying to accomplish.

I made my listview, and it's delete and edit events are working properly, now I want to implement a possibility for user to mark an element as "default". D, E and Def are buttons
Reference
----------------------------------------------------------------
- ref1 - somevalue - somevalue - somevalue - [D] - [E] - [Def]
----------------------------------------------------------------
so that would be a row from a table, I made delete and edit work by handling events from listview,
Private Sub lvMain_ItemDelete(ByVal sender As Object, ByVal e As ListViewDeleteEventArgs) Handles lvMain.ItemDeleting
Dim refFac As new ReferenceFactory
refFac.Delete(e.Keys(0))
EndSub
similar for Editing. But now when I try to get values from Default button, the button wont even do anything...This is the code:
<asp:ImageButton ID="ibtDefault" runat="server" ImageUrl="~/Images/Default16.png" CommandName="Default" />
and for my logic:
Public Sub ibtDefault_Click(ByVal sender As Object, ByVal e As ImageClickEventArgs )
SelectedRef.Name = "Test"
End Sub
I just wanted to test it whether it will run or not by changing the value of my global string that will show which Reference is made default. But it wont even do that...Then I tried with Commands.
Private Sub lvMain_ItemCommand(ByVal sender As Object, ByVal e As ListViewCommandEventArgs) Handles lvMain.ItemCommand
If e.CommandName = "Default" Then
'Dim refID As New Integer

View 5 RepliesIf I select an item from listview, it will get all the records at the database and display it to richtextbox.

After I select it, the 2 richtextbox will be filled with diagnosis and prescription.
I don't have any idea how to do it so I don't have any codes to show yet but I was able to display the records from my database to the listview. The only thing left is when I clicked it, it will display the records.
how can i select an item in the listview from a string. ex.i'm loading the listview w/c: directory folders and i have a checkbox to show or hide hidden folders. no problems there.the problem is when i click an item in the listview and check or uncheck the checkbox, the listview reloads w/a new set of items.

I have been playing with, and researching, this all day and can't figure it out. I have a Windows Explorer style form with a TreeView and a ListView. I've populated the TreeView with directories and when a node is selected, the ListView fills with the contents of the directory associated with that node. No problem there, but I want to be able to select a directory in the ListView and automatically select the associated node in the TreeView, just like it works in Windows Explorer. All the information I've found online tells me how to populate the ListView from the TreeView, but I haven't found any good examples of how to populate the TreeView from the ListView.

Do I really have to go through all this just to find out what item has been selected in a ListView?

Isn't there something fundamental like this? Is absolutely everything in VB.NET buried beneath a colossal heap of bureaucracy?
The correct code:
Private Sub tvFolders1_AfterSelect(ByVal sender As System.Object, ByVal e As System.Windows.Forms.TreeViewEventArgs) Handles tvFolders1.AfterSelect
Dim id3folder As String
[CODE]...
I'm now trying a different approuch to my previous problem with the TreeView/ListView issue I had, this new "sollution" seems to be a bit more easy however I still can't solve it. The problem is to add the remaining listview.subitems, everything I try ether a: crashes app, or b: Only adds one subitem. If you take a look at the code you should see where my problem is.
Private Sub tvFolders1_AfterSelect(ByVal sender As System.Object, ByVal e As System.Windows.Forms.TreeViewEventArgs) Handles tvFolders1.AfterSelect
Dim id3folder As String
id3folder = e.Node.FullPath()
