Hi dmullis,

so what do you mean by "call an ascx page with a javascript function" ?
you can drag & drop the ascx file on your aspx page and when you open the page in browse you will see the result of executed ascx file

Please explain your question in detail. To add the footer decalre the following at the top of your aspx page:

<%@ Register TagPrefix="MYWeb" TagName="Footer" Src="Footer.ascx"%>

and where you want to insert the footer, add the following lines:

<MYWeb:Footer id="Footer" runat="Server"></MYWeb:Footer>

I am not using an aspx page..that would be easy. I hate to get into the details of this because it confuses everyone and the general issue but here goes:

I have an xml page created by other programmers..I cannot "re-do" this some other way. In the xml page, it contains several pages with page ids and their specific elements like textboxes, etc. From these page id's I can call a javascript function such as onclick, onload, etc. Within each of these page ids,at the beginning of the page, there are numerous javascript functions called by the elements. I will have to use a javascript function to call the footer that resides on the ascx page..This xml page will not understand putting
 <%@ Register TagPrefix="MYWeb" TagName="Footer" Src="Footer.ascx"%> at the top of each page id.

I plan to put an onload event with each page id element..( I know how to do this in the XML. I know how to position the footer on each page id.). The onload event should call a javascript function that calls my ascx page. I need to know if javascript can call an ascx page and if this is possible,how to tell the javascript function to call the ascx page.

Man, I don't think it is possible
ascx files are something like the #include directive in the old asp , so ...

hmm, im not quite sure if i understand your question, but if you are trying to get javascript to interact with aspx you can do something like the following:

<input type=hidden id=xfer name=xfer />
<script language=javascript>
  function foo()
    document.forms[0].xfer.value = something;

Then on the serverside use: string s = Request.Form["xfer"];

you can then have the server interpret that and do something to a
<asp:PlaceHolder Runat=server ID="PlaceHolder1"></asp:PlaceHolder>
PlaceHolder1.Controls.Add(new Footer_ascx.Footer());

I wound up having to create a server control and do it this way, because of the deadline.

+"<td width='103'><a href='../pages/ContactUs.aspx' onMouseOut='MM_swapImgRestore()'"
+"onMouseOver='MM_swapImage('Contact US','','../images/controls/footer/contact_on.gif' ,1)'>"
+"<img name='Contact US' border='0' src='../images/controls/footer/contact_off.gif' width='119' height='43'>"

I appreciate all your input. answered my other question about putting the javascript inside the above.
