But I want to I keep the changes that will occur on the form when I go back again and in this way will return to the form without the modifications.....

Is "Form6" already open? If so, then what code did you use for opening it? And where?

i used

Form6 f6=new Form6();

at Form4 ... then at form 7 i want to com back for form 6 i used

Form6 f6=(Form)Application.OpenForms["Form6"];

actully i have more than 30 forms.....when i define button next i use new in previous i use application.OpenForms...!!!!

You could also use the Hide property of the form, so when you click the next button as you mentioned, then the form will be hiden and maintain its data.

Hope i helped :)
