I want to validate a mathematical expression like (a+b)-c in my project. How to do that?
Please can you help me?

Use the custom validator \[(]|\[w]|\[+]|.... But how length is your formula?

Length is not fixed. Is there is any predetermined reqular expression in .NET?

\[(]|\[w]|\[+]|.... this expression is not working....

There is no specific regular expression but you can modify the regular expression already available to make it as custom validator... Else you can use the javascript or vbscript to validate the formula.

I know that but I want to know what will be my regular expression. Can you provide the regular expression?
