If it's a custom control you should be able to find it in your solution or its references. Look in the XAML file what namespace is cwc mapped to.

That sounds like ASP.NET Real World Controls

The tag prefix is not registered.

This article will explain,
how to register tag prefixes:

I think cwc is TagPrefix

For registering Telerik.Web.UI you can use something like this:

HTML

<![CDATA[<%@ Register Assembly="Telerik.Web.UI" Namespace="Telerik.Web.UI" TagPrefix="telerik" %>]]>

and are helpful to access telerik controls using tagprefix as

SQL

<telerik:RadGrid ID="gridview" AllowMultiRowSelection="True" runat="server"
    AllowFilteringByColumn="true" GridLines="None" CellSpacing="1" CssClass="RadGrid_WebBlue"
    Width="100%" Skin="WebBlue" AllowPaging="true" PageSize="50">
