obviously it will delete all the record in registration page because the entire page will load once again.
You can overcome this problem in two way
Tips 1:
Save all the entered data in registration form in session and if you click on edit button in preview page then in pageload of registration page fill the controls from session value.
Tips 2:
No need to create separete page for preview create two table in your page in first table is same as your registration page and second table is same as your
preview page. Bydefault hide the second table now as soon as they hit the button in registration page hide the first table and display he second table using javascript and assign all the values from first table to here ausing javascript.
If you still stucked somewhere please let me know.

make Sure you have Set EnableViewState Property to True

and One More thing

When you redirect page From Another page it Sends Fresh request so there will be no values in TextBox

But Just press back Button of Browser it will have retained Value

or you can also Use Session to Store Data When you redirect

you can use Session like below Code

Session["textBox1"] = textBox1.Text;

and For retrieving Data

textBox1.Text = Session["textBox1"].ToString();

dont forget to mark " Do you like answer" please if answer helped you :)
