Thanks alot Ten,
I am new in SSRS but I am very eager to know more about that, so I think it's good opportunity to learn more detail about SSRS.
And thanks alot to Vani, could you please send me your solution, because I've done that but I got some issue with column that has numeric value.
I mean sometimes the header format will be copy to all of column's cells.
I'll appreciate for your help.
Regards,
Fateme
