VS 2008 Retrieve The Selected Items In A Listbox - Save Them To A Collection
Jan 6, 2010
I want to retrieve the selected items in a listbox, save them to a collection, and then use that collection later. I thought that was simple enough, but when I clear the selected items in the listbox, my collections (items, indices) change. I found this out by stepping through the code.
Basically what I'm wanting to do is move items in the listbox up or down (up in this case), and still keep them selected.
Whats wrong with my code?I need to move the the cursor position at the next item in my listbox for very tick of my timer. And stop my timer when the position is at the end of listbox.
Private Sub Timer1_Tick(ByVal sender As Object, ByVal e As System.EventArgs) Handles Timer1.Tick Dim x As Short
I can't seem to find any answers that work. Here's the setup:
Info class: Public Class ProductStageInfo
[Code]...
maybe I just don't understand the whole collection/index/thing. All the examples I've found are regarding single dimension collections - 'how to find name within this collection', and the responses use strings to search through them, but somehow the Info class is being treated differently, and I'm not sure how to translate this..
i have a button and a listbox. I would like to click the button and it will popup with a save file dialog and then save all items in the listbox to a .txt file.
I added a setting in my.settings, the setting is a listbox, and I know you can put controls in a listbox, but for some reason it will not let me add a toolstripmenuitem to the listbox in my settings. Is there a fix to this?
I am making some kind of calendar where I can add tasks, so I can easily organise my tasks. For it to complete, I have 3 things I can't figure out how to do it:
1. When I launch the program, I want the items in my listbox to be sorted alphabeticly.
2. I want to save the items in the listbox, so if I close the program and reopen it the items are still saved in the listbox.
3. The items in the listbox all start with a date, fe. "13-4" for today. If that date already passed I want that item to be deleted.
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 ... End Next
I want to retrieve all the items in a listbox with a For loop. there are only two itemsin the listbox. I'm able to retrieve the first item in the listbox when the counter of the for loop is 0. when it gets to 1 an IndexOutOfRange Exception is generated.
Here is my code. Dim i As Integer Dim count As Integer=Me.ListBox1.Items.count Dim sel As String For i=0 To count-1 sel=Me.ListBox1.Items.item(i).ToString MsgBox(sel) Next i
I have two listboxes in asp.net. On the click of a button I want to load a list box with the elements of the selected items in the other box. The problem is that this has to be done on the client side because when the button is clicked I don't allow it to submit. I want to call a javascript function onselectedindexchange but that is [code]...

I have a quick question...is it possible to make a "for... each" loop that would go through each selected item of a listbox? What I want to do make sure there are no dupe names in the listbox.
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.

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.
I have a multiselect enabled listbox on the page that is populated from a SqlDataSource. I have another DataSource that retrieves the selected items from the database.I cannot for the life of me figure out how to set all of the selected items in the listbox. I have figured out how to get the first item from the selected items sqldatasource, but I don't know how to set ALL of the items from the sqldatasource as selected. [code]
my vb.net will not use listbox1.selecteditems it always comes up with a blue line underneath even though when i search online everyone is using this. my goal is to get the selected items and list them in a textbox

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.
I'm trying to create a mailto hyperlink to send an email with the body being the selected items from a listbox, all on a seperate line. I have it working to where it will add the selected items but to seperate email panes.[code]...
The code below creates a highlight rect on each of the selected items in a listbox. How can I do the same without selection but rather on mousemove above an item?
Private Sub ListBox1_DrawItem(ByVal sender As Object, ByVal e As System.Windows.Forms.DrawItemEventArgs) Handles dialogue.DrawItem If e.Index <> -1 Then e.DrawBackground() If (e.State And DrawItemState.Selected) = DrawItemState.Selected Then
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"
I want to transfer multiple items selected from a listbox to an access 2007 database using a parameterized query.When I select certain items from the listbox, only first item selected gets stored in the database.Other values selected are not written to the database.My code is as follows.Is my approach towards transferring multiple values correct?Someone
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] .....
