Hello,
in order to represent the structure of a online class I have used the ASP.Net 3.5 TreeView control (the same of the 2.0, I suppose).

The tree is correctly generated with all the nodes and leaves; in case of a leaf, the corresponding TreeNode is created by setting the NavigateUrl property to a certain page that shows some multimedia content.

By going over that leaves with the mouse, the browser shows in the lower toolbar the correct address of the linked page.
But unfortunately, by pressing that node nothing happens!

I've tried to set also the Target property of the TreeNode but it seems not to work,also because in my case I do not want to open the linked page in a frame or in external window but only to redirect the browser to the new page.

Any help?

Thanks,
Davide

Here is an example of a tree view.  Notice that I supplied the "http://" for the "Google" and "Yahoo" nodes.  The "MSN" node does not have "http://" and will not work. 

        <asp:TreeView ID="TreeView1" runat="server">
            <Nodes>
                <asp:TreeNode Text="Class" Value="Class Links">
                    <asp:TreeNode NavigateUrl="http://www.google.com" Text="Google" >
                    </asp:TreeNode>
                    <asp:TreeNode NavigateUrl="http://www.yahoo.com" Text="Yahoo">
                    </asp:TreeNode>
                    <asp:TreeNode NavigateUrl="www.msn.com" Text="MSN"></asp:TreeNode>
                </asp:TreeNode>
            </Nodes>
        </asp:TreeView>

Dear Chris, thanks for your help.

Unfortunately I build programmatically my TreeView so I cannot apply directly this solution.

In my case, the TreeNode is build accordingly the following instruction:

TreeNode t_slide = new TreeNode("<table width='100px' class='testo11'>" + l.Titolo + "</table>", "", "", "disc_view_lesson.aspx?id_lesson=" + s.ID, "");

My page is internal to my webiste so I do not need to use the "http://". Nevertheless, also if for a test I have put a static address of the type http://www.google.com in the TreeNode constructor, it does not work.

Hi,

 Base on your descrition, you click on the treenodes, but there is nothing happen, right?

Whether is there some javascrit error message in the browser's bottom? maybe you need to post more details here, so we can use it to repro your problem as possible as we can, which will be helpful to find the cause of the problem.

If you want to open a new wind when you click on the treenode, you should set the treenode's targer is _blank.
