How to create dynamic reports in VS2005

Question

Hi All,
I'm using VS2005. I want to create a dynamic report (Not crystal report). I've a webform with a list of columns...now user will select the columns he want in the report and clicks a button 'Get Report'. On clicking the button..the report should be generated with the selected columns only.

Can anyone help me regarding this..?

Or, plz tell me how to hide a column of the report (.rdlc file) programatically..

Thanks,
Venky
