Ajax-TabPanel error: make sure the AjaxToolkit.Properties.Resources.NET4.resources are properly imbedded or linked to assembly
<p>I get an error in the design window of asp.net when using ajaxToolkit:TabPanel.  It is inside the container.  The error message says: </p>

<blockquote>
  <p>"...make sure the AjaxToolkit.Properties.Resources.NET4.resources are
  properly imbedded or linked to assembly...."</p>
</blockquote>

<p>My aspx markup:</p>

<pre><code>&lt;asp:TableRow&gt;
  &lt;asp:TableCell runat="server" Width="100%"&gt;
    &lt;ajaxToolkit:TabContainer ID="TabContainer1" runat="server" 
        Font-Bold="True" Font-Size="Small" ForeColor="#336699" 
        Font-Names="Arial" Height="150" Width="100%"&gt;
        &lt;ajaxToolkit:TabPanel BackColor="#CCCCCC" BorderColor="Gray" BorderStyle="Inset" 
              BorderWidth="2" Font-Bold="True" Font-Names="Arial" Font-Size="Small" 
              ForeColor="#336699" HeaderText="Metric1" Height="150px" runat="server" Width="100%"&gt;
        &lt;/ajaxToolkit:TabPanel&gt;
    &lt;/ajaxToolkit:TabContainer&gt;
  &lt;/asp:TableCell&gt;
&lt;/asp:TableRow&gt;
</code></pre>

<p>I have tried several things already: AjaxtToolKit.ScriptManager, added reference to <code>AjaxToolKit.dll</code>, and registered AjaxToolKit at top of aspx page.</p>

<p>I am just trying to insert a tab tool to the web page I am working on.</p>

<p>Any help would be greatly appreciated.</p>
