Maintaining ViewState

[SA]

hi
I have a datagrid bound to a datasource. I am generating the columns
in the datagrid dynamically. I override the loadviewstate method and
recreate the datagrid columns once again. In this way my viewstate is
maintained. now some of the rows in my datagrid have a different style
(they are bold). This information is not maintained in the viewstate.
I am exporting the information available in the viewstate to Excel and
i get only the data without the formatting information. any
suggestions???.

thanks
SA
