Dim I As Integer
For I = 1 To txtnumber.Text
Dim myTextBox = New TextBox
myTextBox.ID = "txtDynamic" & I
myTextBox.Text = "Control Number:" & I
Me.ph1.Controls.Add(myTextBox)
Dim myLiteral = New LiteralControl
myLiteral.Text = "<BR><BR>"
Me.ph1.Controls.Add(myLiteral)
Next
End Sub
Private Sub sum(ByVal cc As ControlCollection)
Dim total As Integer
For Each control As Control In cc
If control.HasControls() Then
sum(control.Controls)
End If
If TypeOf control Is TextBox Then
total += TryCast(control, TextBox).Text
End If
Next
MsgBox(total)
End Sub
Protected Sub btnsumm_Click(ByVal sender As Object, ByVal e As EventArgs) Handles btnsumm.Click
