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>
