3 Stage Multiview With Dynamically Generated Controls?

Let's say I have a booking form which is divided into 3 separate views in a multi view.

View 1: "How many people do you want to book for?" And then just a text box

View 2: "Please enter the details for each of the people" And then a series of dynamically generated text boxes - the number of boxes is determined by the value in the textbox in view 1 (e.g. if the users enters "3" into the text box, there will be 3 series of text boxes like "Details of person 1: First Name <textbox> Last Name <textbox>, Details of person 2: First Name<textbox etc..."

View 3: "Please review and confirm the details are correct:" Displays data entered in view 2.

Here's the difficult part - In order to generate the controls in view 2, I need to know the value of the text box in view 1. This value isn't available during Page_Init as viewstate has not yet been written. But - need to build the controls during Page_Innit. So - I thought why not try to grab the value of the textbox using Request.Form[Texbox1.ClientID]; - this is fine when moving from view1 to view2 but remember - I need to recreate these controls again if the user moves back to view1 or forward to view3 (it is a requirement that the user can move backwards and forwards between the views).

So - User enters value in Textbox in View1, hits the "Next button", we request that value using Request.Form and generate a series of controls dynamically. Then the user clicks "Next" again and moves to view 3 where we would like to show a summary of what they entered. But - we cant because those controls dont exist as we could not create them because the value of textbox1 is not available during Page_Init and we can't use Request.Form as the textbox isn't now part of request.form because we came from view2, not view1.

I can't figure out how to dynamically create these controls and then recreate them during page_innit on each postback so we retain any values the user might have entered.
