Use FindControl to search for a server control for which you have specified the id parameter.

Control ctrl = FindControl("TextBox1");

If you created it programmatically as a literal, you can't use FindControl to find it. When the form posts back, you can use the form collection to see if the value posted back, as in:

Request.Form["test"]

or 

Request["test"]

If the user doesn't check the checkbox, then the form value will not be present, which is something the uses a hidden field to work around.

if you want to find control on code behind file , then you should set this as runat="server", 

literal.text = "<input type=\"checkbox\" id=\"forum1\" runat=\"server\">";



HtmlInputCheckBox test = (HtmlInputCheckBox) Page.FindControl("test");

but whenever page is going to postback you lost state of this control.

May this will give you right solution http://www.codeasp.net/blogs/SumitArora/microsoft-net/841/value-of-dynamic-textbox-lost-on-postback

You can use page init event to generate control

protected override void OnInit(EventArgs e)
{ 
  HtmlInputCheckbox test = new HtmlInputCheckbox ();
  test.id= "test";                 
  pnlControl.Controls.Add(test);
  base.OnInit(e);
}
