hi, try this....

1) Create a base class of Textbox
2) Add Two-property 1) calias 2) ccontrolsource
3) Write following code in INIT method in baseclass

IF !USED(This.calias)
USE This.calias
ENDIF

SELECT (This.calias)

IF TYPE(This.ccontrolsource) != 'U'
This.controlsource = This.ccontrolsource
ENDIF

4) Now in your form use this textbox.
5) Do not mention control source but instead of that write in ccontrolsource
6) Do fill calisa ( Table Name )

If you using a framework then it would be easy to add this code, other wise you can write directly in your TEXTBOX control with little modification. And add write few lines to disable control as needed.

Try out this I think it would help you, let me know if any thing missing….

Thanks
Mihir
