Enabling/Disable FINISH Button of a Wizard Depending on User Input.....

Hi,

I have created a wizard in AX 2012 using wizard wizard... Now i need to put 1 functionality i.e., to Enable or Disable FINISH button based on user input.

I have already tried these 3 ways but without success..

this.finishenabled() -- on SetupNavigation method of wizard class

finishenabled[formrun.tabidx()]= false -- on SetupNavigation method of wizard class

syswizard.finishenable(false, curtabidx(),false) - on Tabpage of wizard form

please do reply if anyone have a solution for this....
