File Not Found

Hello

i keep getting the following error message and cant figure out why

Parser Error Message: File or assembly name Microsoft.Web.UI.WebControls, or one of its dependencies, was not found.

Line 2: <%@ Register TagPrefix="iewc" Namespace="Microsoft.Web.UI.WebControls" Assembly="Microsoft.Web.UI.WebControls" %>

Have you included the System.Web namespace?
Have you included the System.Web dll as a reference?

yes, I have the following line at the top of the aspx page:

<%@ Register TagPrefix="iewc" Namespace="Microsoft.Web.UI.WebControls" Assembly="Microsoft.Web.UI.WebControls" %>

edit-------------------

Its probably best if I include all the code:

<%@ Register TagPrefix="iewc" Namespace="Microsoft.Web.UI.WebControls" Assembly="Microsoft.Web.UI.WebControls" %>
<meta name="vs_showGrid" content="True">
<iewc:TreeView id="TreeView1" runat="server" accessKey="<%# Page %>" ImageUrl="file:///C:\folder.JPG" BorderWidth="0px" SelectedNodeIndex="0" SystemImagesPath="/zzz/">
	<iewc:TreeNodeType></iewc:TreeNodeType>
	<iewc:TreeNodeType></iewc:TreeNodeType>
	<iewc:TreeNodeType></iewc:TreeNodeType>
	<iewc:TreeNodeType></iewc:TreeNodeType>
	<iewc:TreeNode ImageUrl="file:///C:\folder.JPG" Text="Node0">
		<iewc:TreeNode Text="Node3"></iewc:TreeNode>
		<iewc:TreeNode Text="Node4"></iewc:TreeNode>
	</iewc:TreeNode>
	<iewc:TreeNode ImageUrl="file:///C:\folder.JPG" Text="Node9">
		<iewc:TreeNode Text="Node11"></iewc:TreeNode>
	</iewc:TreeNode>
	<iewc:TreeNode ImageUrl="file:///C:\folder.JPG" Text="Node10"></iewc:TreeNode>
</iewc:TreeView>

My Thoughts ------------------------

Would it have anything to do with the fact that I am using this web component with .net v1.0.3705 ?
