In ASP.Net is there anyway to create a form tag (with runat=server) from within the code?

I need to create muliple groups of checkboxes but I don't know how many groups I will need or how many options are in each group.(both of these come from separate database tables)
In asp it was easy. Simplified it was this... and it would create the
the number of checkboxes I needed. And I could do this for each group.
do until RSdob.eof
 <INPUT TYPE='checkbox' value=" & RSdbo_("option") & " NAME='OptionList'>" & RSdbo("optionName")
loop

In ASP.Net I tried to do the following
    Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        Dim i As Integer
        Dim item As checkboxlist
        Dim ckbArray(5) As checkboxlist

        For i = 0 To 5
            ckbArray(i) = New checkboxlist
        Next

        For i = 0 To 5
            ckbArray(i).ID = "ckbarray" & i
            ckbArray(i).Enabled = True
            ckbArray(i).Visible = True
            ckbArray(i).Text = "test"
            Controls.Add(ckbArray(i))
        Next
    End Sub

This does not produce checkboxes (it works in VB.Net and if I change
the checkboxlist to labels it works).
The error messages states that checkboxlist needs to be within a form tag with parameter runat=server.

in ASP.NET u can only have 1 form with RUNAT=server attribute!

Then is there anyway to dynamically create checkboxlists/checkboxes and radiobuttonlists/radiobuttons from code when you don't know how many of these seperate controls you will need at design time?

Yes.

That article says controls can be create dynamically but it doesn't give an example.
In my first post in the example I gave, if the checkboxlist are changed to labels then I can dynamically create the labels but the code doesn't work with checkboxes or checkboxlists.

    Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        Dim i As Integer
        Dim item As label
        Dim lblArray(5) As label

        For i = 0 To 5
            lblArray(i) = New label
            lblArray(i).ID = "ckbarray" & i
            lblArray(i).Enabled = True
            lblArray(i).Visible = True
            lblArray(i).Text = "test"
            Controls.Add(lblArray(i))
        Next
    End Sub

Hi,

I tried the following code and it worked for me, although it adds the checkboxes horizontally:

<%@ Page Language="VB" %>

<script runat="server">

  Sub Page_Load(sender As System.Object, e As System.EventArgs)
    Dim i, n as Integer
    Dim box as HtmlInputCheckBox

    If Page.IsPostBack Then
      i = Request.Form("num")
      For n=0 To i-1
    box = New HtmlInputCheckBox
    formDiv.Controls.Add(box)
      Next
    End If
  End Sub

</script>


<form runat="server">
  <input type="text" name="num"> Number of checkboxes <br/>
  <input type="submit">
  <div id="formDiv" runat="server" />
</form>

Cheers!

marciapz,

  I had a similar issue rendering content from a database. I simply needed more flexibility than the Web Forms framework provided. I wound up directly subclassing IHttpHandler. The folling is C# but easily portable;

  public class Class : IHttpHandler{
        ...
        ...
     private static TemplateWriter tw = new SimpleTemplateWriter();

     public void ProcessRequest(HttpContext context){
          HttpResponse res = context.Response;
          ...
          tw.startHtml(res);
          res.Write("<form>");
          res.Write("<table><tr><td>Login</td><td><input type=\"text\" name=\"txtLogin\"></td></tr>");
             res.Write("<tr><td>Password</td><td><input type=\"password\" name=\"txtPassword\"></td></tr></table>");
      res.Write("<input type=\"submit\" value=\"Login\"></form>");

          tw.stopHtml(res);
   }

    public bool IsReusable{
        get{ return true;
 ...
  ...
}

The TemplateWriter is a custom class I have that reads a file on the server containg the beginning and end of an html template; I design it in Dreamweaver and then cut and paste the code into the file. Makes for nice html, but you can ignore that part.
