I have a problem , which I need to write out a function which is to enabled and disabled button for a form.How can I do it ?

my class function will recevied an Action and the FormName, then base on the Action and FormName, I will enabled and disabled button for that form.

Example :

Form1 :

This form got 7 button :
Button1,Button2,Button3,Button4,Button5,Button6,Button7

When Button1 onclick , I will call the class function to enabled Button2,Button3,Button4
and disabled Button5,Button6,Button7.

I want to do like this, because I got 200 form , and If I not do like this , each form I also need to put in the same code to control to button.
If I got this class function , I just call the function , then everthing will be done.

Anyone can help me ?
Thank you ~~~
