Just tried 40000 with no problems. I don't think there's any reason for it to have a limit beyond how much it would take to lock up your pc which I assume would be quite a large number.


ListView1.Columns.Add("Main", 50, HorizontalAlignment.Left)
ListView1.View = View.Details
For x = 1 To 40000
ListView1.Items.Add("New Item" & x)
Next
