.net - Listbox Selected Item Checking?
Aug 10, 2009My 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

Edit Selected Item In Listbox?
Nov 8, 2007So, 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??
How To Get The ID Number Of A Selected Item In Listbox
Dec 13, 2011I 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?
