How to get the items with ListView control selected?

Question

I want to add a tooltip for items of Listview. I use the code below.

Private Sub ListViewProjectsList_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ListViewProjectsList.SelectedIndexChanged
        If ListViewProjectsList.SelectedItems.Count = 0 Then
            MsgBox("No Items is seledted at all")
        End If
        ToolTip1.SetToolTip(ListViewProjectsList, ListViewProjectsList.SelectedItems(0).Text)

 End Sub

I click one of the item within my listview control.  I think I have already selected it.

It enter into sub ListViewProjectsList_SelectedIndexChanged(). However it pop up a box say "No Items is seledted at all".

Why? How can I get the item selected.

Thanks in advance.

Answer 1

If you click an item that is already selected, then that item will be cleared and the SelectedIndexChanged event will still fire (with no items selected).

Maybe you could explain more what you are trying to do.

Thank you. Paul.

Every time, I select different item within that Listview Control. It also pops up the box saying "No Items is seledted at all".

What I trying to do is below.

I want to add a tooltip for the "item" of Listview, not for the ListView control itself. The latter is easy. However, for the former, the item appears only at run time. How to do it? Thank you!

This time, is it clear?

You can set the ToolTipText property of the ListView item before adding it to the ListView:
