You will not be able to write code to a method at runtime. This is why I suggested you store code where you want then use EXECSCRIPT() to run that code. You just need to put the EXECSCRIPT() in the method you want. When you add the object programmatically to a form at runtime, this object should be sub-class of your own making (e.g., MyTextBox, MyCheckBox) that has the EXECSCRIPT() code in the methods you are interested in.

>Thank You Mark,

To do that I create a checkbox object in which I impose it's click event to check a variable containing some code and then if it was not empty process it. The I fill this Property when I add the object programmatically.
