Second textbox copy form First textbox. But sometime i need to change the second textbox value differ from the first textbox.

It always display the value from the first textbox. It must display new value if i overwrite in the second textbox.

 Thanks.

It sounds like both text boxes are bound to the same data field. Delete the one you don't want and add a new one from the Controls.

But  I want the same text in textbox 1 and 2, but i textbox two the text to be changed..

How should i do that?

Set a rule on the field bound to the first text box that will update the second field.
