Dear Abhishek,
Here are the test you asked for... Completely different project the same result. I know I am asking alor but, could it be possible for you to test it.
Aspx page:
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Default.aspx.cs" Inherits="Test._Default" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title>Untitled Page</title>
</head>
<body>
<form id="form1" runat="server">
<div>
<asp:GridView ID="dgSiparisler" runat="server">
<Columns>
<asp:TemplateField HeaderText="Adet" HeaderStyle-HorizontalAlign="Left">
<ItemTemplate>
<asp:Label ID="lblAdet" runat="server" Text='<%# DataBinder.Eval(Container.DataItem, "DataAdi")%>'></asp:Label>
</ItemTemplate>
<HeaderStyle HorizontalAlign="Left" />
<ItemStyle Width="50px" />
</asp:TemplateField>
</Columns>
</asp:GridView>
</div>
</form>
</body>
</html>
cs page:
using System;
using System.Collections;
using System.Configuration;
using System.Data;
using System.Text;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.HtmlControls;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.IO;
namespace Test
{
public partial class _Default : System.Web.UI.Page
{
Class1 u = new Class1();
protected void Page_Load(object sender, EventArgs e)
{
dgSiparisler.DataSource = u.tbl_Al();
dgSiparisler.DataMember = u.tbl_Al().TableName;
dgSiparisler.DataBind();
StringBuilder sb = new StringBuilder();
StringWriter strw = new StringWriter(sb);
HtmlTextWriter htmlw = new HtmlTextWriter(strw);
//ClearElements(dgSiparisler);
HtmlForm form = new HtmlForm();
Controls.Add(form);
form.Controls.Add(dgSiparisler);
form.RenderControl(htmlw);
}
}
}

Ohh... I am sorry Ersan, as you are about to render the same page which is loading, the server will actually put the gridview inside the Form until it passes the Page_Load. Do this :
Place
<%@ Page ... EnableEventValidation = "false" %>
in the page directive of your page. Now place this in the code behind :
public override void VerifyRenderingInServerForm(Control control)
{
}
Overriding this function will automatically disable the checking of server side form element. And as I have also disabled Event Validation, so any event validation error generation while rendering the Gridview will also be suppressed.
So your server side code will look like :
StringBuilder sb = new StringBuilder();
StringWriter strw = new StringWriter(sb);
HtmlTextWriter htmlw = new HtmlTextWriter(strw);
this.dgSiparisler.RenderControl(htmlw);
string html = sb.ToString();
No need to create a new form element. Just do it, I am sure it will work.

I may be jumping the gun here, but his member page says he is working in Kolkata. At the time you posted this he was probably tucked up in bed! Even if that is not the case, so he helped you a bit yesterday, he has a job to do as well. He will probably get back to you tomorrow, or more likely after the weekend. Have some patience before you repost.
If you have knowledge, let others light their candles at it.

Hi Guys
I have a web app, and in this web app I have a list box.
This list box displays file names of word documents that relate to the project which is displayed in the rest of the app.
I have the File names displayed, but the value of the list box is set to the full file path.
My question is, how can I open the documents when a user selects a document and clicks on the "Open Document" button?
I used a ListBox because I'm quite tight on space...
Thank in advance
edit: I'm using C#
oooo, the Jedi's will feel this one....

You can initiate the File Save As Dialog box on button Click.

How do you do that? I've tried looking on google, and all I can find are Response.TransmitFile() or Response.WriteFile() which just write the file into the browser just before the page starts.
I was playing around with creating a hyperlink object, and setting the navigate url to the files url, but I cannot find a way to activate it.
I would have used hyperlinks if space and neatness were not so much of an issue...
oooo, the Jedi's will feel this one....

That's it, just set the content type first so that the browser knows it's a download, or perhaps a file to be opened in the browser.

How do you mean, activate ?

By activate, I mean somehow make it think it has been clicked. I was just experimenting with that one. I suppose I was just trying to cheat. 
Thank you for your reply.

Use this when user clicks the button to download the file :
Response.Clear();
Response.ContentType="application/word";
Response.AppendHeader("Content-Disposition","attachment; filename=yourfilename.doc");
Response.TransmitFile(serverfilepath);
Response.End();
Cheers.

If you want one, write one or search one. If you are expecting someone to spoon feed, try some other site.

To show the modal in one event of the codebehind you only have to use:
ControlWithExtender_ModalPopupExtender.Show(); is that what you need??

ok sorry for the delay! i was working ^^
so, you need to show the modal when the user clicks on a row of a asp table?? isn't a Gridview?? with gridview is easier!
well let's start from zero, if you're using ajax ModalPopUpExtender you can give the extensor to any asp control... like
<asp:button ID="MyTestButton" Text="I dont know" runat="server">
<cc1:ModalPopupExtender ID="MyModal" runat="server"
Enabled="True" TargetControlID="MyTestButton"
BackgroundCssClass="modalBackground"
PopupControlID="Pnl_Modal"
CancelControlID="Btn_Cancel" DropShadow="True">
</cc1:ModalPopupExtender>and your panel to show must be hidden
<asp:Panel style="display:none;" CssClass="modalPopup" ID="Pnl_Modal" runat="server" Height="99px" Width="297px"
BackColor="#66CCFF">Here the textboxes you need and the save button<asp:panel>ok then! assuming you've a grid like
<asp:GridView ID="GV_MyData" runat="server" AutoGenerateColumns="False"
DataKeyNames="Id_Pelicula" DataSourceID="LQDS_MySource"
onselectedindexchanged="GV_MyData_SelectedIndexChanged">
<Columns>bla bla bla and your button in every row</Columns>
</asp:GridView>
so in the OnSelectedIndexChanged Event you can add
MyTextBoxInsideTheModal1.Text = values.Actor_Estelar;
MyTextBoxInsideTheModal1.Text = values.Titulo;
MyModal.Show();
assuming values is obtained from a qry using the SelectedDataKey.Value of the GV... i'm explaining myself?

but i want asp table and i generate it dynamically so the asp button on which i want to show modal popup also
generated dynamically...
so how can i show modal popup on it..???
for testing i create one test.aspx like this...
<%@ Page Language="VB" AutoEventWireup="false" CodeFile="test.aspx.vb" Inherits="test" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" >
<head runat="server">
<title>Untitled Page</title>
<script type="text/javascript" language="javascript">
function onOk(){
return true;
}
function ShowModalForNew(){
var myBehavior = $find('mpe');
myBehavior.show();
$find('mpe').show;
}
</script>
</head>
<body>
<form id="form1" runat="server">
<ACT:ToolkitScriptManager runat="server" ID="ScriptManager1" EnableScriptGlobalization="true" EnableScriptLocalization="true" />
<div>
<asp:UpdatePanel ID="uptmp" runat="server" UpdateMode="conditional">
<ContentTemplate>
<table>
<tr>
<td>
<asp:Button ID="Button1" runat="server" Text="Button" />
<a href="#" style="display:none;visibility:hidden;" onclick="return false" id="dummyLink" runat="server">dummy</a>
</td>
</tr>
</table>
<act:ModalPopupExtender ID="ModalPopupExtender1" runat="server"
TargetControlID="dummylink"
popupcontrolid ="Panel1"
backgroundcssclass="modalBackground"
dropshadow="True"
cancelControlId="CancelButton"
BehaviorId = "mpe" />
<asp:Panel ID="Panel1" runat="server" style="display:none; width:200px; background-color:White; border-width:2px; border-color:Black; border-style:solid; padding:20px;">
Are you sure you want Delete Text?
<br /><br />
<div style="text-align:right;">
<asp:Button ID="OkButton" runat="server" Text="OK" />
<asp:Button ID="CancelButton" runat="server" Text="Cancel" />
</div>
</asp:Panel>
</ContentTemplate>
</asp:UpdatePanel>
</div>
</form>
</body>
</html>
and i called the javascript thr codebehind like this,....
Partial Class test
Inherits System.Web.UI.Page
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
If Not IsPostBack Then
Button1.Attributes.Add("onclick", "ShowModalForNew();")
End If
End Sub
End Class
if you run this it shows, modal popup but, it get disappeared...
if it worked properly, then i can add attribute to the dynamically generated asp button, as shown in code behind....
now you get what i want..? but thanks for reply... it also helpful to me related to modal popup extender...

Ok i understand your problem! I had try your test.aspx and asign the modal pop up dinamically and use it with javascript is a problem... unless you work with datagrid. I personally recommend u to use a gridview and fill it dinamically like the asp table you use... Why i'm recommending this?  is just because the asp table isn't have any event (in the server) that helps you in your problem, with gridview you only add the 'ShowSelectButton = true' and program (in server side) the OnSelectedIndexChanged (of the grid) the modalPopUpExtender.show(); and that's all! i think...
greetings
