用户如何选择要在gridview中查看的数据

Question

I have a gridview that contains 100 of rows I want that user can select how many rows in the grid he want to view (Means header and data of that header). Have you any idea. Example:

SL     NO       NAME     DATE       END DATE           SUB TOTAL             TOTAL 
==================================================================================


==================================================================================

User can choose he want to see only SL NAME SUB TOTAL TOTAL in gridview and after that Grid will display data like this

SL            NAME                   SUB TOTAL                          TOTAL
==============================================================================



==============================================================================

You can change the visibility of columns based on user preference by setting the Visibility property on each column. If you're using an ObjectDataSource, you can control the number of rows by setting PageSize .
