Dynamic GridView problem

[palgre]

HI All,

I want to disply dynamic Columns and Dynamic Header to that column in
a GRID VIEW. The application is kind of TimeSheet for entering weekly
hrs for a month.

1. First of all I want to disply Column based on number of weeks in a
MONTH. e.g. July have 5 weeks so total number of Columns shopuld be 5
(or if a month has 4 weeks then disply 4 columns)

2. I want to disply header as the last day of the week (e.g. 1st week
of July ends on 7th July) then header should display "July weekending
7 JUL."

3. A footer for every column that will disply total for a given week
of a month.

I will appreciate if any one of you can provide me Pointers/Code.

Thanks
