ActiveWidgets • XML - Paging

The problem I'm having is trying to figure out where I should set the row count for the grid using synchronous xml data retrieval and then draw the grid.

When it first displays no data is shown and the row #'s are negative. If I page the grid will be refreshed and shown correctly. I tried to have the document write out the grid within the response function and the grid wasn't writter correctly either.

Any help would be appreciated.

Here's the code I have so far -
<html>

<head>

    <title>ActiveWidgets Grid</title>



    <!-- ActiveWidgets stylesheet and scripts -->

    <link href="grid/grid.css" rel="stylesheet" type="text/css" ></link>

    <script src="grid/grid.js"></script>

    <script src="grid/browserSniffer.js" type="text/javascript"></script>





    <!-- Include patches here -->

    <script src="grid/paging1.js"></script>





    <!-- grid format -->

    <style>

        .active-controls-grid {height: 400px; font: menu;}



        .active-grid-column {border-right: 1px solid threedshadow;}

        .active-grid-row {border-bottom: 1px solid threedlightshadow;}

    </style>
