I'm having some difficulty with a sorted & grouped listbox in WPF vb.net 3.5 that has an items source bound to an ObservableCollection.
What I want to be able to do is to retrieve a piece of data from the ObservableCollection items source depending on what item in the listbox the user has selected.I've almost got it working but because the listbox is sorted it does not match the index of the items source.

As I previously mentioned, because the lstBox is sorted and also grouped the index's don't match up.Does anyone know how I can get the correct information I want from the List Source depending on the selected item in the list box?
Ok, so I have a listview on one form, and when a button is pressed it opens up a new form with the contents of the selected listview item and it's subitems in a series of textboxes. The user can then change the data in the textboxes and either press save to make the changes or cancel to close the window. What command would I use to change the selected listview item and subitems to whatever is in the boxes?
this is the code that populates the boxes:
Private Sub Form_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim appeditcontents As String = main.passlist.SelectedItems(0).ToString

View 5 RepliesI am making a password program that remembers what the password is for and what the password is. I have two listboxes: 'listbox1' for what the password is for, and 'listbox2' for the password. I also have a remove button. I would like it so when you press the remove button, the selected item in listbox1 is removed and the password in listbox2 is also deleted. The passwords are stored in two settings: what, and pw. The items that will be deleted will have the same value. By value i mean they will be the same number item. E.G. the 1st item, or the 3rd item in the list.

In my Windows Form I have a ComboBox that is filled by a Stored Procedure with a list of names. I have the Combobox set for AutoComplete to "Suggest" and From "ListItems". When a user starts to type in and the AutoComplete does not find any matches in the listitems the user can tab out of the ComboBox and leave what they typed in the combobox even though it is not one of the Valid Items. Is there a way to check the Comboxbox to make sure of of the selected Items has been selected?

i have a sub that checks all drives on a computer;
Dim getInfo As System.IO.DriveInfo()
getInfo = System.IO.DriveInfo.GetDrives
For Each info As System.IO.DriveInfo In getInfo
TextBox1.Text = TextBox1.Text & info.Name & vbCrLf
Next
this shows all drives in textbox1. now if i select the drive i want, i can then check the free & total space with this sub;
Dim cdrive As System.IO.DriveInfo
cdrive = My.Computer.FileSystem.GetDriveInfo(TextBox1.SelectedText)
TextBox2.Text = TextBox1.SelectedText & " has " & cdrive.TotalSize / 1024 / 1024 / 1024 & "gb total space" & vbCrLf
TextBox2.Text = TextBox2.Text & "and " & cdrive.TotalFreeSpace / 1024 / 1024 / 1024 & "gb free space"
all this is good if i select the drive i want to check. but if i only click the drive, since no text is selected, the second sub does not work.is there a way to check at which index the cursor is, grab the item of the index, and pass it to the sub so i don't have to select the text itself?

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).
