Listbox findstring issue ? why result focus at bottom of Listbox ?

[Nicomendox]

Hi. Everyone. first of All sorry for my bad English. hope I can explain to what I want to do.
Advanced Thanks...

I listed All Fonts into Listbox.
Then I try to Find with TextBox1_TextChanged

When TextBox Changed Result Focus Bottom of Listbox.

How Can I show found Result on top Row of ListBox ?

Private Sub Form2_Load(sender As Object, e As EventArgs) Handles MyBase.Load

        Dim fonts As InstalledFontCollection = New InstalledFontCollection()
        Try
            For Each FNT As FontFamily In fonts.Families
                ListBox1.Items.Add(FNT.Name)
            Next FNT
        Catch

        End Try
    End Sub

Private Sub TextBox1_TextChanged(sender As Object, e As EventArgs) Handles TextBox1.TextChanged
        If TextBox1.Text = "" Then
            ListBox1.SelectedIndex = 0
        End If
       
        ListBox1.SelectedIndex = ListBox1.FindString(TextBox1.Text)
    End Sub

why not like this result at top row ?

The ListBox only scrolls far enough that the selected item is in view. That's how it works because that's how it's designed to work. If you had read the documentation for the ListBox class then you'd already have the answer to your question, which is why you should ALWAYS read the documentation first. If you had done that then you'd have seen the TopIndex property described thusly:

Gets or sets the index of the first visible item in the ListBox.

It seems fairly obvious that, if you want that item at the top of the list, you assign the index of that item to the TopIndex property.
