IF condtion Syntax


I would like to check one control value before displaying the control in portal.
but Here if condition is only checking true or false value .but i need to check some other string or value.please give the need ful help.whats the syntax in wm7.0 CAF

This is a common use case and can be approached two ways:

  1. With an IF control, where the ‘value’ is set to an expression that resolves to a true/false value.
