ListView.SelectedItems is always empty

Question

Hello there. I have the following code:

private void folderView_SelectedIndexChanged(object sender, EventArgs e) {
            libraryExplorer.selectedItems.Clear();
            libraryExplorer.selectedItems = folderView.SelectedItems;
            if (folderView.SelectedItems.Count == 1)
                toolStrip.Items[1].Enabled = true;
            else
                toolStrip.Items[1].Enabled = false;
        }

What it does, is it enables the "Rename folder" button in a toolStrip if only one item is selected, if not, it disables it. The libraryExplorer is a class I created with functions that helps with other stuff, so that doesn't matter.
My problem is, that folderView.SelectedItems.Count always returns 0.
I am not programmatically setting any selected items. You can only select stuff by clicking and the ListView has multiSelect set to true. (Although that's another problem I have to tackle, multiSelect doesn't work even if it is true, holding control doesn't do anything)

It could be that I am misunderstanding how a ListView works, and I would be extremely happy if someone enlightened me. :)
With regards,
Alvin.

Answer 1

Try removing the libraryExplorer.selectedItems.Clear( ) line.

This should also solve the problem of MultiSelect, which apparently does not have effect.

Answer 2

Make sure MultiSelect is enabled for folderView

 .folderView.MultiSelect = true;

Answer 3

I have come across this before, don't try and test for the number of selected items in the SelectedIndexChanged event use the ItemSelectionChanged event.
