Q:

RDLC Format Textbox Expression

I have a textbox that should display "interest" value in this format for example "(5%)".  The Dataset Interest field has datatype System. Decimal.  If I don't format the textbox it just displays "5" on the report page. 
Currently in my designer I have  
Interest «Expr»

Then the report page displays 
Interest 5

Back to my problem I want to display something like this
Interest (5%)

How can I format the Interest expression «Expr»? 
Please help.  I'm new to RDLC. 

A:

Just concatenate the expression. 
For example:
="Interest (" & Fields!Interest. Value & "%)"
