First, I believe that others have already created  a Web Part that does what
you are trying to do, for instance:
http://tinyurl.com/7y646

You might begin there and search for others.

Second, the "Page Not Found" error  is likely because the SharePoint config
database doesn't know about the page  you are trying to use. Read up on
direct mode pages  in the "60 Hive" that are ghosted into IIS Application
cache and then used by SharePoint as indicated in the site  Definition files.
Using FrontPage you can easily add a page to your site because it
understands the underlying SharePoint database. But it takes some effort to
include a new page in the file  system.

Third, signing a DLL requires a "strong name key" file (can be generated
using the VS.NET sn utility using the -k option), access to the source code,
and the VS.NET compiler. Modify the settings in the AssemblyInfo.cs file.

Much more could be said on each of these topics but I'll wait for your
follow-up reply with specific questions.

You cannot strong name a DLL that you do not have the source to.

check instructions on how to deploy the control  on his site.

The problem  which I am facing "Page not found" is not coming when I remove the tree  view control  from page.when control is again copied into the page

It is showing the page  not found error....the error  lies in control......

I am not getting that....

And one more Question is when I am trying to access the virtual  server settings and sites  under the virtual servers I am getting Security Exception

For that I have copied the following Code:

1 SPGlobalAdmin gadmin=new SPGlobalAdmin();

2 Context.Items[SPGlobalAdmin.RequestFromAdminPort]=true;

3 Page.RegisterHiddenField("__REQUESTDIGEST",gadmin.AdminFormDigest);

It is working  ………… if we save the project  in _layouts Folder

When I create  new folder  in inetpub/wwwroot and there I am getting Error

At 3 line of the above code

The error that I am getting "Cannot Complete this action Please try again"

Hmmmm. I don't know where the error  in the control  you build lies.

The code you have listed simply inserts a FormDigest tag into the page. This
is required whenever updating the SharePoint database. Not sure why you
would need it to show the Site hierarchy in a treeview.

Not enough information to solve  the "Cannot Complete this action Please try
again" error.

Why I copied the FormDigest code because is I have to create  new sites
and may be delete some sites  also that's why I placed...

And next the Error:

Steps:

I Add the reference to the treeview  control
And then I drag the control  from toolbox
I added some nodes into the tree..control
I added one button control and label also
Execute the application
First it shows the page  with controls for one sec and then it is saying
Page not found


When I execute the app without treeview control

Page is viewing No Problem

I Copied the DLL file  into the Bin folder  of the project...and in
reference I select DLL file contained in the Bin Folder Any Wrong in
this?
