NEW POST: Error running standard SLN project

bkosscus — Wed, 07 Nov 2007 04:12:54 GMT

I am trying to run this project and it compiles fine (VS2005, XP Pro) and the first page appears no problem. But any action on the page (any click in grid or calendar) the app bombs out with an error of "Value cannot be Null. Parameter name InString" on line 39 (bytes = Convert.FromBase64String(this._viewstateStorage.Get(id).Value);) of the ViewStateElim.cs class in the "protected override object LoadPageStateFromPersistenceMedium()" method. I have not changed one line of source code anywhere. Am I missing something here? Is there a configuration setting I am supposed to be changing here in the web.config? Please advise.

My ultimate goal here is to be storing this in a SQL Server DB.

Thanks,

Bob

What Is ViewstateEliminator?

ViewstateEliminator is not just one implementation for stripping viewstate (in asp.net 2.0 haven't ported to 1.1 yet) from hitting the client, it provides a hook so that you may manage viewstate in your own way. Basically its an interface that you implement and handle the saving/loading of viewstate.

Currently Provided Storage Mediums:
SQLServer
SessionState
Application Cache

Project Description
This is a solution for stripping out viewstate before it hits the client. The thought for making this utility was the following, viewstate has no real use fullness on the client; besides reconstructing the control tree and as a state bag. Most of the time developers turn viewstate off on controls because it tends to become huge and slows down the streaming of content.

Even when using Ajax API's such as Microsoft Ajax and Anthem.Net viewstate is still passed back and forth. So even though we get partial page updates we are still passing through that big chunk back and forth, what we have done is we have disguised the problem but not solved it.

What has been done is eliminated viewstate being sent out to the client and being stored in another medium.

Current Supported mediums:
*SQL Database
*Session

Current .Net Framework Supported is 2.0

Version 1.1 released.

CLOSED ISSUE: Create a Configuration Block

maximoguerrero — Wed, 02 May 2007 15:57:14 GMT

right know the utility works off two App-Setting keys. Should have its own Configuration section as well.

CLOSED ISSUE: Life of Viewstate on un-authenticated.

maximoguerrero — Wed, 02 May 2007 15:56:54 GMT

One bug that we do have is that right now this works great in portal or site where the user has been authenticated. In un-authenticated pages we don't know that the life of viewstate might be. The scenario is what if i visit a page, leave my desk for 30 mins and come back. If we use the Session Storage session time out is usually 30 mins. And If we use SQL storage its up to the DBA basically. The issue is more of what is a acceptable life cycle for that 30 mins, 1hr, 2hr....what is really needed.
