UltraGridExcelExporter formatting not getting exported


I create a grid which displays a huge number of records. Not all the records are visible at one time to the user.
The user has to use the scrollbars to access the remaining rows.

i have specified a alternate row color.


When i export the grid using UltraGridExcelExporter, the alternate row color formatting is exported in the excel only for those rows which were visible and the one which i viewed using the scroll bar. the rows which the user had not viewed the alternate row color is not exported.


How do i resolve this error
