I am getting the Invalid length issue frequently in my application. Using of SessionPageStatePersister from earlier implementation hiddenfieldpagestatepersister did not resolve the issue.
Can any body please help me out?

We have received some other reports about similar issues that happen randomly on our clients servers. However none of our customers managed to isolate the problem in sample which we can inspect and debug. The only thing I could advice you is to temporarily disable the viewstate compression (you can still keep the HTTP compression though) and verify whether the problem replicates. Note that since the issue replicates on a random basis you may need some time to test the page before you confirm that the problem is resolved when viewstate compression is disabled.

I am also getting same sort of exception with sitefinit, and after some investigations i have some points to make, which may help to replicate and relsove the issue.
I have deployed a page with sitefinity which contains a asp.net's custom control and then reterived its viewstate by simply following these steps :- Right Click on page -> select View Source option and then find the value for __Viewstate hidden field
REF:-
input type="hidden" name="__VIEWSTATE" id="__VIEWSTATE" value="/wEPDwUKMTkxNDY1OTk5NGRkuqjLsqCspQ/KzOgJiU/nXOTrq+ZuE7MNLMEBN8U2Ilc=" />
It Contains some telerik controls like "RadMaskedTextBox and RadGrid" :-

And used online decoders to decode the viewstate value and it works fine.
To verify same you may use follwing decoders :-
http://ignatu.co.uk/ViewStateDecoder.aspx or http://lachlankeown.blogspot.com/2008/05/online-viewstate-viewer-decoder.html
Now, if on the same page I add radasyncupload Telerik controls like and then reterive its viewstate and try to decode, it will throw you error " Couldn't decode the View State. The error was: 'Invalid length for a Base-64 char array."

I believe that there are some specific telerik controls which are causing issue in my case its radasyncupload.
For you reference you can verify the same at following url also :-
http://demos.telerik.com/aspnet-ajax/asyncupload/examples/overview/defaultcs.aspx
Please suggest.

As you probably know the idea of viewstate compression is minimizing the Page footprint as well as reducing the bits sent over the wire. This benefits are achieved by changing (compressing) the viewstate on the server before it is send to the client and decompressing it before it is restored on the server on a postback. Since the compression actually changes the viewstate string saved in the hidden field, it is expected that Base64 decoding tools fail to decode it on the client when it is compressed. This explains why you observe the problem on our live website, because we have viewstate compression enabled there.
As to the scenario where viewstate can't be decoded after an AsyncUpload is added to the page - I am afraid that I would need a sample code to debug locally. I would also need the exact web config settings and RadControls version that replicates the problem on your side.
I hope this helps.
