Dim index As Integer
For index = 1 To RadioButtonList1.SelectedValue
Dim name_tb As New TextBox()
'validator
Dim name_req As New RequiredFieldValidator

name_tb.ID = "name_tb" & index
name_req.ID = "name_req" & index
name_tb.TextMode = TextBoxMode.SingleLine
tabelcell.Controls.Add(name_tb)
'tabelcell add in trow
'trow then added in htmltable
div.Controls.Add(htmltable)
Me.PlaceHolder1.Controls.Add(div)
