Hi Xenophon,
From the page code you provided, you're dynamically creating the Html
HIdden field, is that any particular requirement on this? Does the problem
occurs if you statically declare the html field in your aspx page and
access it in serverside code?
If anything I missed, please feel free to post here.

| I added a Hidden Form Field to a form in the code behind.
| The value is being set in JavaScript client-side, but it is not
| persisting to the server in the PostBack.
| I know the value is being set properly because it displays in the
| document.write method.
|
| Create a simple page and paste the below in the code-behind (ASP.NET
| 1.1-SP1)
|
| using System;
| using System.Collecti ons;
| using System.Componen tModel;
| using System.Data;
| using System.Drawing;
| using System.Web;
| using System.Web.Sess ionState;
| using System.Web.UI;
| using System.Web.UI.W ebControls;
| using System.Web.UI.H tmlControls;
|
|
| public class WebForm1 : System.Web.UI.P age
| {
| protected System.Web.UI.W ebControls.Link Button linkButton;
| protected System.Web.UI.H tmlControls.Htm lInputHidden hdfGmt;
|
| private void Page_Load(objec t sender, System.EventArg s e)
| {
| HtmlForm thisForm =
| (HtmlForm)this. FindControl("We bForm1");
| linkButton = new LinkButton();
| linkButton.Text = "click";
| linkButton.Clic k += new
| EventHandler(li nkButton_Click) ;
| HtmlInputHidden hdfGmt =
| (HtmlInputHidde n)thisForm.Find Control("hdfGmt ");
| if ( hdfGmt == null )
| {
| hdfGmt = new HtmlInputHidden (); // This line
| always runs. It should only run once.
| hdfGmt.ID = "hdfGmt";
| hdfGmt.Name = "hdfGmt";
| hdfGmt.Value = "0";
| hdfGmt.EnableVi ewState = true;
| LiteralControl litGmt = new LiteralControl( );
| litGmt.ID = "litGmt";
| litGmt.Text = @"
| <SCRIPT Language=""Java Script"">
| <!-- hide from old browsers
| var curDateTime = new Date()
| document.xxxxxx .hdfGmt.value=(-(curDateTime.ge tTimezoneOffset ()/60))
| document.write( document.xxxxxx .hdfGmt.value)
| //-->
| </SCRIPT>";
| litGmt.Text =
| litGmt.Text.Rep lace("xxxxxx",t hisForm.Name);
| thisForm.Contro ls.Add( linkButton );
| thisForm.Contro ls.Add( hdfGmt );
| thisForm.Contro ls.Add( litGmt );
| }
| }
| override protected void OnInit(EventArg s e)
| {
| InitializeCompo nent();
| base.OnInit(e);
| }
| private void InitializeCompo nent()

| this.Load += new System.EventHan dler(this.Page_ Load);
