Tree View works through VWD but not via local host or from a remote browser.

Running the application through visual web developer and it works fine. But through local host or remotely, I get the following error:

Server Error in '/' Application.

The code in the page:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"

"http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">

<html>

<head>

<form runat="server">

<asp:SiteMapDataSource ID="mySiteMapDataSource"

runat="server" />

<asp:TreeView ID="myTreeView" runat="server"

DataSourceID="mySiteMapDataSource" />

</form>

</body>
</html>

The sitemap file code:

<siteMap

xmlns="http://schemas.microsoft.com/AspNet/SiteMap-File-1.0">
<siteMapNode title="Home" url="~/Default.aspx"

description="Home">
<siteMapNode title="TreeViewDemo" url="~/TreeViewDemo.aspx"

description="TreeView Example" />
<siteMapNode title="ClickEvent" url="~/ClickEvent.aspx"

description="ClickEvent Example" />
<siteMapNode title="Loops" url="~/Loops.aspx"

description="Loops Example" />
</siteMapNode>

</siteMap>

I'm at a loss as it appears it's exactly as the book describes it.

Key thing to note is

Quote:

System.Web, Version=1.0.5000.0

Your app is running in .NET 1.x, and DataSourceControls in general are .NET 2.0 or better controls. Make sure the .NET framework 2.0 is installed and that you have the virtual directory setup for .NET 2.0.

Thank you for this information. I checked what version is installed via add/remove programs and I see .net 2 framework is installed. I went to IIS and see that it is using 1.1. Could someone point out how I can tell IIS to use 2.0 instead?
Thanks so much.

Found it, Thank you.
