I want to get the value of an item selected in a list view. I want to sotore the value of the columns of the item selected in a diffrent variable. the problem is that I can only get the value of the first column and I don't know how to get the value of the other columns. I need to add another variable and store the value of the second column in that variable.
For Each sItem As ListViewItem In lvwTorneos.SelectedItems
torneoseleccionado = sItem.ToString
seccionseleccionada = lvwTorneos.SelectedItems(0).Text

I have a CheckedListView (suggested in a post I read, and it seems to fit my needs) which I populate with the filtered names of the files from within a selected folder. Then the user selects the ones to process, by using the checkboxes. So basically it is a single column text box with checkboxes down the left hand side.
What I've been trying to do is get the selected text (i.e. the name of the file) and put it in a string array for later use.
I've used various forms of: For each item as .....ListViewItem......Next and also various forms of for x = 1 to Listitem.count......Next
e.g.
CODE:
Ensuring that the filename text goes into the str array.
I want that on Form_Load,First Item that is selected is highlighted.See the image aatached,U all got to know,What i want to know.
Mine Code as follows-
Public Class Form1
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim lCount As Integer
For lCount = 1 To 5
[code].......
I'm trying to figure this small issue out, I need to keep whatever selection the user selects highlighted/selected even if clicking in another row in the listview. The only way I could get this to work prior was with 'lvwStrd.Items.Item(0).Selected = True..However this breaks my program as the index isn't correct, due to the '0', is there a way I can keep whatever item they selected selected even while clicking other rows in the listview(they are empty, there are only one to two options at a time).

View 1 RepliesI thought that instead of directly downloading the images, usic, or whatever to the computer right away-why not have the user pic and choose. So, the transfering of the items that the user might want to download is sent to a new form. I have a picturebox that shows up a X symbol showing that it can't be loaded.
Here's a code just so you guys can see:
PictureBox1.ImageLocation = ListView1.Items.IndexOfKey
The one I wrote above I'm still working on.
I tried different methods such as:
Private Sub ListView1_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ListView1.SelectedIndexChanged
PictureBox1.ImageLocation = e.tostring
In WinForms (Vb.Net / Framework 3.5), I've created a BindableListView control that has a DataSource property that accepts IDataReader's, DataTable's, Array's, Generic Lists and Single objects. I also added the ability to alternate colors when the data is bound to the ListView (I put in sorting also by default with support for numeric & date time). What I have not been able to figure out yet is how to change the selected item's color from the System color (without changing the system color which I don't want to do). I've used the ItemSelectionChanged and SelectedIndexChanged to change the BackColor of the ListViewItem but the selected color always overrides the BackColor (HideSelection doesn't work because it only does that when the control loses focus). My question, Is there a way to change the selected items color (without drawing it myself)?
