this is vb.net

My question is why the lstDisplay is not showing line by line? Is printing after 5 lines and so on. How do you fix that and why is doing that? thanks

Public Class Form1 Dim i As Integer Dim userInfo(4) As String Private Sub btnSaveUser_Click(sender As Object, e As EventArgs) Handles btnSaveUser.Click

For i = 0 To userInfo.Length - 1

userInfo(i) = txtUserNamePhone.Text txtUserNamePhone.Clear() lstDisplay.Items.Add(userInfo(i))

Next

End Sub

End Class
