ListView selection bug?

[hansaplast]

The selection anchor in a listview is not resetted when SelectedItems.Clear is called.

Place a ListView with a few items on a from. Next, set ListView.View = "Details". Add a button and add the folowing code

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
    Dim idx = Me.ListView1.FocusedItem.Index
    If idx < Me.ListView1.Items.Count - 1 Then idx = idx + 1
    Me.ListView1.SelectedItems.Clear()
    Me.ListView1.Items(idx).Selected = True
    Me.ListView1.Items(idx).Focused = True
    Me.ListView1.Focus()
End Sub

Select two or more (not all) items and press the button. After it is pressed hold SHIFT and DOWN arrow. In my case the previously selected items (before pressing the button) are reselected. How is this possible and is there a way to reset the selection anchor?

You need to change the FocusedItem property.

ListView1.SelectedItems.Clear()
ListView1.FocusedItem = Nothing
ListView1.Items.Item(2).Selected = True
ListView1.FocusedItem = ListView1.Items.Item(2)

Property 'FocusedItem' is 'ReadOnly'

Which version of VS are you using? I tested and copied that code from VS 2005 IDE.

Man, that does look like a bug in 2003. I guess that's why they changed it in 2005. I'll see if there is a work around.
