Hi Brian,

AS for the large Viewstate problem you met, I think Bruce's suggestions are
informative and reasonable. Generally the Page's ViewState will contains
all the controls' viewstate on the page. And most control only perisist
their particular display settings(properties) in ViewState. However, the
ASP.NET Template dataBinding controls such as DataGrid, DataList.....
will store all the binded datas(rows ) into the ViewState, that means if
the datagrid contains lots of rows of data, the ViewState will also
increase to a very large size. Here are some tech articles discussing on
the ASP.NET's ViewState and some have mentioned the performance concerns:

Hope helps. Thanks.
