Ajax TabContainer intermittently dissapears on Postback

[cukiwap]

I am developing a GIS web app (mapping) in C# ASP.net. I have an Ajax TabContainer housing several TabPanels with a table. The table contains other content such as the map window, scale bar etc (all from the ESRI WebAdf toolkit).Here's a slimmed down version of my table without the other content...\[code\]<table id="MainTable><tr><td> <ajax:TabContainer runat="server" ActiveTabIndex="0" id="TabContainer" CssClass="ajax__tab_xp"> <ajax:TabPanel runat="server" HeaderText="Online Mapping Service" ID="TabPanel1"></ajax:TabPanel><ajax:TabPanel ID="TabPanel2" runat="server" HeaderText="Postcode"> </ajax:TabPanel> <ajax:TabPanel ID="TabPanel3" runat="server" HeaderText="Coordinates"> <ContentTemplate> </ajax:TabPanel> </ajax:TabContainer> </td> </tr> </table>\[/code\]On Postback at runtime my Tabcontainer sometimes dissapears. This issue is not browser specific.So far I have tried with no success to...[*]Set Z-Index with Relative positioning for the TabContainer[*]Include a JQuery script to 'show' the TabContainer...\[code\] <script type="text/javascript" language="javascript"> $(document).ready(function() { $("#TabContainer").show(); }); </script>\[/code\]Is there some C# I can include in the code behind along the lines of?...\[code\]Public void page_Load(object sender, EventArgs e){ TabContainer.show()}\[/code\]Fairly new to programming and trying to figure out how to 'always show' or 'always ontop' the TabContainer.Thanks
