Dim numOfDesiredControls As Int16

Protected Sub Page_Load() Handles form1.Load

Try
numOfDesiredControls = Convert.ToInt16(txtEnter.Text)
If Not numOfDesiredControls = 0 Then
For i As Int16 = 1 To numOfDesiredControls
Dim txtTest As New TextBox
txtTest.Text = "dynamicTextBox"
txtTest.ID = "dynamicTextBox" + i.ToString
txtTest.AutoPostBack = True
' txtTest.EnableViewState = False
Form.Controls.Add(txtTest)
AddHandler txtTest.TextChanged, AddressOf dynamicEventHandler
Next
End If
Catch ex As Exception

End Try
End Sub

Protected Sub dynamicEventHandler(ByVal sender As Object, ByVal e As System.EventArgs)
' If the event handler gets fired, reflect this by changing the text of lblConfirm
Dim txt As TextBox
txt = CType(sender, TextBox)
lblConfirm.Visible = True
lblConfirm.Text = "Event handler " + txt.Id + " fired: " + txt.Text
End Sub
