<p>In the Ajax toolkit you can use a Tab Container and add TabPanels to this. </p>

<p>I have some controls that I want to be able to use across all tabs and the tailor the tabs with other controls as neccessary. </p>

<p>My question is how do I reuse a panel on multiple tabs? 
Essentially I after something like this</p>

<pre><code>&lt;TabContainer&gt;
&lt;tabPanel1&gt;
&lt;contentTemplate&gt;
&lt;pnl1&gt;&lt;/pnl1&gt;
//other controls here 
&lt;/contentTemplate&gt;
&lt;/tabPanel1&gt;

&lt;tabPanel2&gt;
&lt;contentTemplate&gt;
&lt;pnl1&gt;&lt;/pnl1&gt;
//other controls here
&lt;/contentTemplate&gt;
&lt;tabPanel2&gt;
&lt;/tabContainer&gt;


&lt;pnl1&gt;
//some controls here
&lt;/pnl1&gt;
</code></pre>

Make the panel a user control and then drop the user control in each tab panel.
```
```
<TabContainer>
  <tabPanel1>
    <contentTemplate>
      <uc1:MyControl id="myControl" runat="server" />
    </contentTemplate>
  </tablPanel1>

  <tabPanel2>
    <contentTemplate>
      <uc1:MyControl id="myControl2" runat="server" />
    </contentTemplate>
  </tablPanel2>
</TabContainer>

<uc1:MyControl id="myControl3" runat="server" />
```
```
