Loop Through Selected Items In A Listbox In VB?

Oct 22, 2009

I am binding my listbox to a dataTable, the reason why i am using a listbox is for multiple selection, the user can select more that 1 item, when the user has selected there items, i need to save them into the db, line after line. heres my code, i cannot get the listbox to display all the selected items in my test page.for now in my test page, i just want to show the selected indexes of the items, and then in my next step i would want to add then indexes to the database, for now i just want to loop and display all the selected indexes.

Protected Sub Page_Init(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Init
'1. Create a connection
Dim conn As New MySqlConnection(ConfigurationManager.ConnectionStrings("MyConn").ConnectionString)

Loop Through All Selected ListView Items

Oct 7, 2011

I have this script which is designed to loop through all of the selected listview items, and delete them from the ftp server. - The list view item names are exactly the same name as they are on the FTP server.

For i As Integer = 0 To ListView1.Items.Count - 1
Dim ftp As New FTPclient(host.Text, username.Text, password.Text)
ftp.FtpDelete(ListView1.SelectedItems(i).Text)
Next

Some info:
The FTP server works fine! I'm using it in other places in my script, and those functions work fine. ftp.FtpDelete works fine as a function, I've used it to delete single files before. It doesn't delete any of the files, it just gives me a load of exceptions.

A first chance exception of type 'System.Net.WebException' occurred in System.dll
A first chance exception of type 'System.ArgumentOutOfRangeException' occurred in System.Windows.Forms.dll

Listbox: Only Loop Through SELECTED Values Collection

Mar 17, 2009

Is there a way to to combine line's 1 and 2? I only want to loop through a list of the selected items in this listbox. This works just fine, I just wondered if there was a collection of selected values returned that I could use to avoid having to do it this way.

For Loop1 = 0 To MyListBox.Items.Count - 1
If MyListBox.Items(Loop1).Selected = True Then
...

Selected Items In Listbox To Textbox?

Jul 6, 2010

I've got a bound listbox, SelectionMode is MultiSimple, ValueMember is FacultyID, DisplayMember is FacultyName. I'm trying to pull selected items from the listbox and display in a textbox. Here is my code:

Dim dview As DataRowView
For Each dview In lstFaculty.SelectedItems
txtSelectedFaculty.Text &= txtSelectedFaculty.Text + DirectCast(lstFaculty.SelectedItem, DataRowView)("FacultyName").ToString() & vbCrLf
Next

I'm not getting the results I want. If I've selected "Mickey Mouse" and "Donald Duck", then I get "Mickey Mouse" 3 times in the textbox. If I select "Mickey Mouse", "Donald Duck", and "Foghorn Leghorn", then "Mickey Mouse" gets displayed 4 times in the textbox.

Exporting Selected Items From ListBox To Textbox

Jul 24, 2009

What I have is a listbox and a text box. I want to be able to select the items in the listbox (selection mode is set to multiextended). The problem is

Dim path As String = ListBox2.SelectedItem & " " & ListBox1.SelectedItem & ".txt"
'the line above creates a path with the title of an item from listbox2 + listbox1 and adds the .txt extension.
For Each item In ListBox3.SelectedItems
TextBox1.Text = item
Next
'this just makes it do nothing.

I have also tried diffrent methods to export an item title to a text file. for example I tried:
Dim path As String = ListBox2.SelectedItem & " " & ListBox1.SelectedItem & ".txt"
For Each item In ListBox3.SelectedItems
File.CreateText(path)
Next
'this just gives me a IO exception
It does create a file but it does not contain anything.

Forms :: Loading Listbox Selected Items From A Database?

Sep 14, 2011

I was writing a program that would save the contents of a listbox to a database and wanted to reload the users' choices when the opened up that particular row again. My first thought was to do it with two for loops, just as I used to do in VB6, but I thought there must be a better way to do it. And there was. Sort of. It basically involves using the SelectedObjectCollection class.For this demo, you'll need a listbox called Listbox1. Set selection mode to something other than "One" or else it won't work as expected

Dim items(0 To 3) As String
items(0) = "One"
items(1) = "Two"

Transferring Selected Items From ListBox Into 3 Separate Textboxes

Oct 13, 2009

I have a listbox populated with items which are the numbers 0-10. I need to know how to make the app transfer the selected items into 3 separate text boxes. First it should total the the cumulative values of the selected numbers & place that value into the 1st box. Then is should list the total number of items selected from the listbox & place that number into the 2nd box. And finally it should give me an average of the selected items, now this part I've got down, as I can input the first 2 numbers manually into the boxes & will get a correct response in the 3rd text box.

Here's what I have thus far on my code,
Public Class Form1
Private Sub Form1_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
'fills list box with values
For dblRates As Double = 0 To 10 Step 1
lstScores.Items.Add(dblRates.ToString)
[Code] .....
