TabContainer is an ASP.NET AJAX Control which creates a set of Tabs that can be
used to organize page content. A TabContainer is a host for a number of TabPanel
controls.
Each TabPanel defines its HeaderText or HeaderTemplate as well as a ContentTemplate
that defines its content. The most recent tab should remain selected after a postback,
and the Enabled state of tabs should remain after a postback as well.
The control above is initialized with this code. The italic properties are optional:
<ajaxToolkit:TabContainer runat="server"
OnClientActiveTabChanged="ClientFunction"
Height="150px">
<ajaxToolkit:TabPanel runat="server"
HeaderText="Signature and Bio"
<ContentTemplate>
...
</ContentTemplate>
/>
</ajaxToolkit:TabContainer>

You can change the look and feel of Tabs using the Tabs CssClass property. Tabs
has a predefined set of CSS classes that can be overridden. It has a default style
which is embedded as a WebResource and is a part of the Toolkit assembly that has
styles set for all the sub-classes. You can find the default styles in the Toolkit
solution in the
"AjaxControlToolkit\Tabs\Tabs.css" file. If your
CssClass does not provide values for any of those then it falls back to the default
value. In the example above the default style is used. To customize the same the
user would have to set the CssClass property to the name of the CSS style and define
the styles for the individual classes so that the various elements in a Tab control
can be styled accordingly. For example if the CssClass property was set to "CustomTabStyle"
this is how the css to style the tab header would look:
.CustomTabStyle .ajax__tab_header {
font-family:verdana,tahoma,helvetica;
font-size:11px;
background:url(images/tab-line.gif) repeat-x bottom;
}
