Online Viewstate Viewer / Decoder for Asp.Net 2.0

I got frustrated trying to find an online viewstate decoder for ASP.Net 2.0(.aspx), so wrote my own. You can use it below. NOTE! this is very basic; if you do something wrong you will get a generic error so make sure you copy the viewstate carefully (Firebug in Firefox makes this easy!).

Also, if you have a large viewstate it will take a while for the Treeview to build as I am just using the MS TreeView control which is very verbose in its HTML output.

Breaking news : World's first (possibly) online hex file viewer written entirely in Javascript!

    Dude, you are a legend; definitely didn't want to be running EXEs downloaded from the web to achieve this - thanks :)

    There is a very nice Firefox plugin (ViewStatePeeker by geek111222) to do the same but it does only work with Firefox 3.5 :(

    Any Chance of getting a copy of the Source? I'd like to incorporate a tool like this in my Error logging and debugging tools.

    Hi C Penney, I copied the original source for this from a CodeProject article, I think (it was a long time ago). I then converted it from Winforms to Webforms (a trivial exercise). So if you use Google you should be able to find the original code. Cheers.
