treeview control made with VS.NET 2003 for DNN 2.1.2

Clicking on the first root node works fine , but when I click on any other node, the following error occurs:

Failed to load viewstate. The control tree into which viewstate is being loaded must match the control tree that was used to save viewstate during the previous request. For example, when adding controls dynamically, the controls added during a post-back must match the type and position of the controls added during the initial request.
Anyone know how to avoid this error. I tried turning off viewstate in the control, but that didn't appear to help resolve this error.

Differences between .net 1, .net 1.1, .net 2.0 and .net 3.0 #2
Hi, This seems to be a common question, but i havent got an answer yet:(Can, any one please explain me the differences between these versions.If you keep your feet firmly on the ground, you'll have trouble putting on your pants! There are too many differences for one email - - from 1.0 to 1.1 (not a whole lot of real change, other than fixes, at least compared to 1.1 to 2.0) With 2.0, there were many new declarative controls, with many new ideas added in With 3.0, it's a superset of 2.0 - instead of replacing the installation completely, it just 'added on' new functionality - I would...

Sharepoint 2003 - .net 1.1
Hello !As a consultant, I was asked to develop a simple web application using .net 2.0 and a SQL Server 2005 database. I tried to deploy that application at the client's site : Windows Server 2003, Sharepoint 2003, IIS 6 (with .Net 1.1 and 2.0).The thing is that the application is to be deployed under the default web site used by sharepoint with .net 1.1, without being managed by sharepoint.Actually, when accessing the app from a remote computer, the browser shows a 'Page cannot be displayed'. How can get my application to work side by side with sharepoint and the 2 framework ver...

Running server controls compiled for .NET 1.1 in .NET 2.0
Hello, I have tried upgrading our ASP.NET 1.1 application to .NET 2.0 by using Web Application Projects, and it works beautifully. We use several 3rd party controls that we bought for use in .NET 1.1 and these seem to just work in .NET 2.0, except that I get an intermittent problem with one of them. Should DLLs compiled using .NET 1.1 simply work, except if they access classes that have been removed from the framework in .NET 2.0? If I have both .NET 1.1 and .NET 2.0 present on the machine and the ASP.NET application is configured to run using .NET 2.0 and I have a DLL compiled using .NE...

.NET 2.0 with VS .NET 2003
I installed .net 2.0 using vs .net to configure my web application  with .net 2.0.Now .net 2.0 and .net 1.x both are installed on my pc.There is nothing ASP.NET tab in IIS folder it possiable to run it with .net 2.0 You should have a tab on your website config in IIS when you right click the site that allows you to choose which version to run. Either way it does not matter. .NET 2.0 is useless to you unless you write your site with VS 2005. .NET 2.0 for the most part is backwards compatible but there were a few breaking changes. If you were using something in yo...

Where is the ADO.NET Sybase driver for .NET 1.1 and .Net 2.0?
Hi All Does anyone know where I can get the Sybase drivers for ADO.NET for both versions, 1.1 and 2.0/3.0? Cheers Chris Burrell Hi Chris, There is no release of ASE ADO.NET Provider 2.0 (I assume you refer to ASE provider, not ASA - if ASA please port to sybase.public.sqlanywhere.general). For the 1.1 Provider: It is available in the ASE SDK for windows or the PC Client CDRom included with ASE product. On the SDK its available as 12.5.1 and 15.0 On ASE PC Client I think 12.5.1 is part of ASE 12.5.X and 15.0 is part of ASE 15.X 2.0 provider should release som...

.NET v1.1 SP1 and .NET 2.0 beta 2
Hi all I want to install VWD and .NET 2.0 beta 2 on the same machine that I am using Delphi.NET and .NET v1.1 SP1. I am considering jumping from Delphi to C# and this is an ideal way to do it. I do however have too many web applications on the v1.1 framework that are published on servers that do not support 2.0 as yet. Can these 2 versions of the framework co-exist so I can carry on in Delphi with existing sites but start new ones in VWD? I did take the chance on one of my machines and both VWD and Delphi seem to compile their respective web apps okay. I have not tested deplo...
