Question

How can I highlight a Listview item on MouseHover event in VB.net,
just like windows explorer?

Answer 1

Set the HoverSelection property of your ListView control to True. However, if you want it to be selected immediately, you can implement it manually. For instance, you could try something like this:

Private Sub ListView1_MouseMove(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles ListView1.MouseMove
    Dim currentItem As ListViewItem = ListView1.GetItemAt(e.X, e.Y)
    For Each item As ListViewItem In ListView1.Items
        item.Selected = False
    Next
    If currentItem IsNot Nothing Then
        currentItem.Selected = True
    End If
End Sub

Make sure, though, that the HideSelection property on the ListView control is set to False, otherwise the selection will not be shown unless the list has the focus.
