1.Add runat="server" to input..

<input id="tbHTML" runat="server">

you will access in code behind..

2.Else use find control

System.Web.UI.HtmlControls.HtmlInputControl tbHtml= this.FindControl("tbHtml") as System.Web.UI.HtmlControls.HtmlInputControl;
tbAsp.Text=tbHtml.value;

Make sure the Id of ur Input element is unique in page...than you can try like this.

tbASP.Text=Page.Request["tbHTML"].ToString();

Edit Vice Versa

  <input id="id" value=<%= TextBox1.Text %> />

Amit I hope you will still be able to see my reply. I just want to ask. From this approach that you provided how can I do this vise versa? I mean this time copying from asp textbox to html input element.
