hi there,
my tabcontainer is always rendered as hidden.
this is the asp code
<td class="text1"> <ajaxToolkit:TabContainer runat="server" ID="TabContainer1" Visible="true"> <ajaxToolkit:TabPanel runat="server" ID="TabPanel1" HeaderText="TabPanel1"> <ContentTemplate> TabPanel1 </ContentTemplate> </ajaxToolkit:TabPanel> <ajaxToolkit:TabPanel runat="server" ID="TabPanel2" HeaderText="TabPanel2"> <ContentTemplate> TabPanel2 </ContentTemplate> </ajaxToolkit:TabPanel> <ajaxToolkit:TabPanel runat="server" ID="TabPanel3" HeaderText="TabPanel3"> <ContentTemplate> TabPanel3 </ContentTemplate> </ajaxToolkit:TabPanel> </ajaxToolkit:TabContainer> </td>
and this is how it renders
<td class="text1"> <div class="ajax__tab_xp" id="ctl00_ContentPlaceHolder1_TabContainer1" style="visibility:hidden;"><div id="ctl00_ContentPlaceHolder1_TabContainer1_header"><span id="__tab_ctl00_ContentPlaceHolder1_TabContainer1_TabPanel1">TabPanel1</span><span id="__tab_ctl00_ContentPlaceHolder1_TabContainer1_TabPanel2">TabPanel2</span><span id="__tab_ctl00_ContentPlaceHolder1_TabContainer1_TabPanel3">TabPanel3</span></div><div id="ctl00_ContentPlaceHolder1_TabContainer1_body"><div id="ctl00_ContentPlaceHolder1_TabContainer1_TabPanel1"> TabPanel1 </div><div id="ctl00_ContentPlaceHolder1_TabContainer1_TabPanel2" style="display:none;visibility:hidden;"> TabPanel2 </div><div id="ctl00_ContentPlaceHolder1_TabContainer1_TabPanel3" style="display:none;visibility:hidden;"> TabPanel3 </div></div></div> </td>
can any advise me how to fix this please?

it may be obvious to most people but the first div is meant to have the style="visibility:hidden;" but the control is never rendered to the screen, i.e. i cant see the tabs.

I've dynamic TabContainer (in code behind), andyourTabContainer.ActiveTabIndex = 0; helped me to solve this issue.
I also have this same problem where the tabcontainer and its tabpanels are always hidden. The HTML markup is all there when you view source of the page but the container and panels have a style attribute of visibility:hidden.
This displays fine in IE6 but under Firefox 1.5.0.12 the tabs are always hidden.
Does any one have any ideas why it does this?
I managed to fix my problem.
The problem was I had a calendar extender control within the tabpanel that had its ondateselection property set. For some unknown reason with that property set, Firefox refuses to display the tabcontainer.
