I don't think it's possible to do it without full page post back.. (If I am wrong, please let me know how!!)
So, I decided to put a not-visible button in master.master page. The code follows below.
<%@dotnet.itags.org. Master Language="C#"
AutoEventWireup="true"
CodeFile=" Master.master.cs"
Inherits="Master" %
<!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 id="Head1" runat="server">
<!--General Stylesheet-->
<link rel="stylesheet" href="http://links.10026.com/?link=css/gen_style.css" type="text/css" />
</head
<body style="border:0px; margin:0px;"
<form id="submitTicketForm" method="post" runat="server" enctype="multipart/form-data">
<asp:ScriptManager ID="ScriptManager1" runat="server" />
<asp:UpdatePanel ID="MainLoginPanel" runat="server">
<ContentTemplate
<!--Top Logo-->
<div class="headerTop">
<div id="header">
<div class="logo"></div>
<div class="login">
<asp:Panel runat="server" ID="LogOutPanel">
<asp:Button OnClick="LogOut_Click" runat="server" ID="LogOut" Text="Click here to logout" Width="142" CssClass="myBtn" />
</asp:Panel>
</div>
</div>
</div
<!--Tab_Panel-->
<asp:Panel runat="server" ID="Tab_Panel">
<div class="tabTop">
...
</div>
</asp:Panel>
<div class="contentplaceholder">
<asp:contentplaceholder id="mainContent" runat="Server"></asp:contentplaceholder>
</div>
<asp:Button id="UploadButton" Visible="false" runat="server" Text="Submit" CssClass="myBtn" OnClick="sendData" />
</ContentTemplate>
<Triggers>
<asp:PostBackTrigger ControlID="UploadButton" />
</Triggers>
</asp:UpdatePanel
<!--Page Footer-->
<div class="footer">Footer</div>
</form>
</body>
</html
Then the below is the code for NewTicket.aspx. If I press the btn_sendData button, I need to trigger the UploadButton button in the master's page.
<%@dotnet.itags.org. Page Language="C#"
MasterPageFile="~/Master.master"
AutoEventWireup="true"
CodeFile="NewTicket.aspx.cs"
Inherits="NewTicket"
Title="SPN Ticketing System - Submit a New Ticket" %
<%@dotnet.itags.org. Register Assembly="AjaxControlToolkit"
Namespace="AjaxControlToolkit"
TagPrefix="ajaxToolkit" %
<asp:Content ID="Content1" ContentPlaceHolderID="mainContent" Runat="Server">
<asp:FileUpload ID="fileChoose" runat="server" />
<asp:Button id="btn_sendData" runat="server" Text="Submit" CssClass="myBtn" OnClick="TriggerMasterUploadBtn" />
</asp:Content
Now, the below is the partial code from NewTicket.aspx.cs.
protected void TriggerMasterUploadBtn(object sender, EventArgs e)
{
Control btnControl = Page.Master.FindControl ( "UploadButton" );
Button btn = (Button)btnControl;
//I have the control but I don't know what to do!
}
I've been pulling my hair for hours for this thing.
Your help is GREATELY appreciated!
Thank you again.
It is not possible to do a file upload without doing a full post back. If you have the fileupload inside the update panel you will need to add a trigger to the button that will take care of the uploading. There have been many posts on this forum about this, and some have some good work arounds.

There is alink on one of the threads that is to an MSDN page that listed all the controls that currently do not work with update panel but I can't seem to find it. If anyone does, please post it here.
