ListView ItemActivate Delay

I haven't found a way to change this delay, it's a built-in setting.

The problem is that the MouseDown event actually has a delayed response, setting only the SelectedItems property after .

You need to do it manually: use the MouseClick event. This fires if the item is clicked, even if it is already selected. It won't fire when empty space is clicked.

Private Sub list_MouseClick(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles list.MouseClick
    Dim item As ListViewItem = list.GetItemAt(e.X, e.Y)
    If Not IsNothing(item) Then
        do your stuff here
    End If
End Sub

      

        
        
        
      

    

You can simulate hot tracking by handling this event

Private Sub list_MouseMove(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles list.MouseMove
    Dim item As ListViewItem = list.GetItemAt(e.X, e.Y)
    If Not IsNothing(item) Then
        list.SelectedItems.Clear()
        item.Selected = True
    End If
End Sub
