Cassini webserver and Viewstate

[Jonas Nilsson]

I have a webapplication that runs with out any errors under
MS IIS 5 / 6.

But when I try to run it under MS Cassini web server i get this error if i
have
a big Viewstate ( A datagrid or a treecontrol with a lot of data ).

the viewstate is proably truncated, some proxy servers will do this also, so
the real fix is to reduce the viewstate payload. your site uses will be
happy also.
