Visual Studio 2010 - Performing Action On Each Selected Item In Listbox?
Jun 6, 2011
I am populating a listbox with a large list. The user then has the option of choosing multiple items from this list. I then want to perfrom a few actions on only the selected items.I cant figure out how to only perform the actions on only the highlighted selections.
'I have tried all combinations of
For each Listbx.SelectedItems.ToString in ListBx.Items.ToString
For each Listbx.SelectedItem in Listbx.Items
'etc, etc
''Performing actions here but it is still doing it with all entries

I know about VSTO/VSTA, and I also know that some VBA functionality (with .NET syntax of course) can be done in .NET. There is definitely a learning curve going from VBA to .NET without VSTO. My question though is, can everything that is done in VBA somehow be recreated in .NET without VSTO?
The reason is because I am converting my VBA application into .NET for several reasons: I want to take advantage of OO, my class libraries will be better available for use, and for fun. I wouldn't be too happy if I got so far in only to learn of some limitations.

I've bound a listbox to a database; how do I get the value of the selected item out as a string? Something like
temp = listbox1.SelectedValue.ToString()
Only returns
"System.Data.DataRowView"
rather than the actual value.

I have a form with a list box and a button. The list box is filled with text files from a folder. When you click the button whatever file is selected in the list box is then opened and each line of that file is added as an item in a list box on another form.I'm not sure what to code for if something in the first list box is not selected.

My code follows. I have six items (indices 0-6) and I'm trying to check if one has been selected or not. If not, then messagebox yells at you to select one. If it does, it tells you what you have selected. I'm having a horrible brain fart and contemplated coming here for about 45 minutes as I couldn't get it.
If ListBox1.SelectedItem.ToString <> "" Then
MessageBox.Show("You selected " + ListBox1.SelectedItem.ToString)
Else
MessageBox.Show("Please select an item.")
End If

In .NET there doesn't seem to be a property to find the item just selected in a multi-select listbox; SelectedIndex always shows the first selected item. From memory VB6 had the ListIndex property that changed accordingly... Why remove a useful property ?

So, I need to be able to edit an item that has been selected in a listbox. I need to do so with a button click event. Theoretically, I know how to do this, because I know how to add an item, and how to remove one, and how to insert an item at a specific location.
'Dim strinput As String
'Dim Item As Object
'Dim index As Integer = lstList.Items.IndexOf(item)
'strinput = InputBox("Edit This Item")
'lstList.Items.RemoveAt(lstList.SelectedItem)
'lstList.Items.Insert(index, strinput)
however, this does not work at all. what am I doing wrong??

I am trying to use a listbox to hold categories from one table in a database and by clicking on the categories in the listbox it will display data from another table in the database that is linked to those categories. One table has a field called ID and the other has categoryID and categoryID is linked to ID so it displays the numbers from ID.I am using this:
daSamples.SelectCommand.CommandText = "SELECT * FROM tblSamples WHERE tblSamples.categoryid =" & (lstCategory.SelectedIndex + 1)
daSamples.Fill(dsSamples, "tblSamples")
Currently, however with this if you delete a category from the table with ID in it then it changes the values of the selectedindex in the listbox which messes up the data that gets displayed. How can i change this so instead of using the selectedindex from the listbox, it takes the ID from the selectedindex?
