Viewstate decoder

Here are two viewstate helpers:

This one allows you to take the viewstate in your page and paste it into this online viewstate decoder. It will decode as string or as a tree. This is the one I use.

This ones is really good if you want it to scan a lot of pages at once. You open up your web browser and it will look at each link you go to:

This one is a firefox plug-in:

The 'name' does not exist in this context

Sometimes Visual Studio 2005 will hiccup and you will get the error:

"The 'name' does not exist in this context"

I fixed it by doing the following:

• Exclude file from project


• Build


• Exit VS 2005


• Open VS 2005


• Add back to project and build again

This fixes it. The other alternative is to reference the control directly in the content placeholder.
You can check out the Microsoft Forums posting for it at:

Custom XML Schema Generator

I found this it and thought it may be useful in getting around the ASP.NET Dataset issue where it ignores namespaces in the xml files. But unfortunately it ignores namespaces too. But possibly it can be modified to support it. If someone manages to modify it to support such things please let me know and I can post it here.

If you have found any other generators or know of a workaround to the Dataset namespace ignoring issue let me know.

ClientScriptManager.RegisterForEventValidation !!!

It seems in .NET 2.0 it is more picky on doing postbacks from controls. Here is an article that gives a sample on how to use ClientScriptManager.RegisterForEventValidation so you avoid this mess.

The other option is to add the following to the <@ page directive:

EnableEventValidation="false"
