Working in Visual Studio

Objective: I am trying to have my server side vb code construct a file name 
for use with my client side JavaScript code to then save the file to the 
web. My saving to the web method is working with a preset test filename.



The issue I have is that when I put this JavaScript in the source code of an 
asp:content holder of a masterpage container, it is not able to see any 
server side controls, one of which is returning my filename I want to use.



In a standard HTML page where I worked out the code method it works fine, so 
I know the method works.



It is only in asp:content page, where there is no HTML that I cannot read 
the server side control.



I can read a HTMLInputText control in the asp:content page so long as it is 
not set to runat="server", but then my server side vb code cannot see it to 
write my file name to it for use with the JavaScript code.



I either need a way to read the server side control from the asp:content 
page with JavaScript,  or write to the HTMLInputText control not set to 
runat="server" when the server responds, or a different approach that allows 
me to get my filename in a way that the JavaScript can read it.



Here is a snippet of the code up to where the error on page occurs:



<%@ Page Language="VB" MasterPageFile="MasterPage.master" 
AutoEventWireup="false" MaintainScrollPositionOnPostback ="true" 
CodeFile="APcontent.aspx.vb" Inherits="APcontent" title="Accounts Payable" 
%>



<asp:Content ID="Content1" ContentPlaceHolderID="ContentPlaceHolder1" 
Runat="Server">





<script language="javascript" type="text/javascript">

// <!CDATA[

function File1_onclick() {

   var Var1 = document.getElementById("TextBox1").value; 'ERROR OCCURS HERE

         document.write(Var1);

//File saving code is here.

}

// ]]>

</script>



        <asp:TextBox ID="TextBox1" runat="server" 
Width="472px"></asp:TextBox>





</asp:Content>

You'll probably get a better response on the 
microsoft.public.dotnet.framework.aspnet newsgroup.
