have a little problem with this EPIServer error:
CS1061: 'System.Web.UI.Control' does not contain a definition for 'CurrentPage' and no extension method 'CurrentPage' accepting a first argument of type 'System.Web.UI.Control' could be found (are you missing a using directive or an assembly reference?)

when i try to access a method with a parameter from my ascx file. 
The ascx file:

```
<div id="nav">
    <ul role="menu">
      <li <%# GetMenuClass(Container.CurrentPage)%> role="menuitem">
            <%= GetNewsPage %>
            <%--<a href="#">News</a>--%>
        </li>
        <li <%# GetMenuClass(Container.CurrentPage) %> role="menuitem">
            <%= GetClientPage %>
            <%--<a href="#">Clients</a>--%>
        </li>
    </ul>
</div>

```

The method in codebehind:

```
protected string GetMenuClass(PageData page)
    {

        if (page.IsSelected(CurrentPage))
        {
            return "class=\"menu-item selected\"";
        }

        return "class=\"menu-item\"";
    }

```

what i want to achieve is something like this (if news page is selected):

```
<div id="nav">
<ul role="menu">
<li class="menu-item selected" role="menuitem"> News </li>
<li class="menu-item" role="menuitem">
<a href="#">Clients</a>
</li>
</ul>
</div>
</nav>

```

I'm greatful if some one can help.
