Dynamically Add/Remove columns ssrs at runtime according to my select query

Hi All,

Today,i came with a problem which is common but i am unable to find any proper solution of this, so here i describe it,

I want to Add/remove columns  from ssrs report, according to user selection,

suppose my table structure is like,

A|| B||C||D ||E||

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

1|| abc|| xbg|| ih||hfj||

2|| kdj|| kjhv|| fh||jjh||

now,i have  to provide column selection to the user, like

if user select, B,D then my report should be like,

B|| D||

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

abc|| ih||

kdj|| fh||

So, How can i do this, i know about the option of Hiding Column, but i do not want that, because i have 100 + columns,

Xml Updation is also an option but it is a very lengthy process and i am unable to find proper solution for this,

Please help me on this...it is very urgent for me...

Thanks in advance....
