I'm using a wizard control with 4 steps, when I use the previous button to navigate back to the previous step the page reloads but at the bottom of the page.Instead of showning the whole of the page, the user views the footer of the site and the previous button and next button.I'm sure there is a very simple answer to this but I just can't figure out how to get the page to reload to the top.

I'm using the Wizard control to collect information about the users:
- Step1: User personal information
- step2: User account information (email. username, password ...)
- step3: User agreement
- step4: display all the inputted information before submitting
On Step2, after the user has inputted username and clicked the Next button (to go to Step3), I verify whether the username is already being used. If so, I want to display an error message and stop to process to go to Step3.
Here is the code that I'm using:
Code:
Protected Sub Wizard1_NextButtonClick(sender As Object, e As System.Web.UI.WebControls.WizardNavigationEventArgs) Handles Wizard1.NextButtonClick
Dim WhichStepId As String = Wizard1.ActiveStep.ID 'Just to see the active step
Dim WhatActiveStepIndex As Integer = Wizard1.ActiveStepIndex 'Just to know active step index

I have two web forms. One (Form1) with dropdownlist and button. Second (Form2) with the textbox , button and gridview.
I have the product list about 10000 items. When user go to Form1 and click the button. It will go to Form2 in which user will type the text in the textbox. And then click the button for filtering the productlist. the result will show in the gridview which will have select button in the first column.
When user select the product, Form2 will close and go back to Form1. The selected product will put in the dropdownlist in Form1.
How to do in the coding?
(1) Select button in the gridview with closing Form2, selected product put in the drop down list in Form1.
I'll try to specify my problem as simple as possible! I have a problem comunicating between 2 pages; Products.aspx and ProductDetail.aspx. On Products.aspx i have about 15 DDL's on the left side (all set to autopostback), and 1 ListView ond the right side. Results in my ListView control are based on selcted items from DLL's on the left. Every single result in Products.aspx has a dynamical hyperlink to the ProductDetail.aspx. Now when I click on specific product in ListView I'm redirected to ProductDetail.aspx page, and everything works fine! If I click on the Back button in IE or FF it works also fine because it returns me to the previous Products.aspx page and all my results based on selected items in DDL's are still there!
The problem comes when causing some more autopostback's in ProductDetail.aspx page, because every autopostback is counted as a new page request and therefore i have to click Back button in IE or FF for more then 1 time to come back to the previous Products.aspx page.
I tried to implement code BELOW in ProductDetail.aspx.vb but it does not completly fulfill my expectations, becase all my searching criteria are lost when returned to the previous page (Products.aspx)
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
If Not Page.IsPostBack Then
ViewState("ReferrerUrl") = Request.UrlReferrer.ToString
End If
End Sub
Protected Sub BACK_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles BACK.Click
Response.Redirect(ViewState("ReferrerUrl").ToString)
End Sub
Does anybody knows any other solution how to come Back to previous page with only ONE CLICK without loosing searching criteria?
I have four pages and user enters certain information and navigates to the next page. In the last page, when user clicks on submit button it will redirect him to the confirmation page. Once the user is in the confirmation page and clicks on back button, all the fields in the previous pages must be non-updatable. Note: User can use the back button to view his previous data but not-updatable anymore.

View 3 RepliesI have a Default(contains the sign-out button) and Login page, once the user is not authenticated, it will always redirect the user to login page.
So the scenario is when the user hit the sign-out button it will redirect him to the login page which is good. My problem is, when the user hits theprevious or back button from the login page,it will still read the authorization cookies and redirect him to the default page. which should not be the case. the user should be redirected to login page when authentication is invalid.
I've read some solutions on the net, but still it doesn't work for me. below are the codes I've used for my sign-out function
[Code]....
By the way, when the user is authenticated, the previous or back button is available/enable for the user.
Considering three webpages. In all pages there are gridivews. The gridview columns has numeric data.
When user click on data figure suppose 29 then it redirects to other page with 29 records. In the redirected page if user again click on data suppose 12 then it redirects to another page with 12 records.
I want to give option to user that if form third page he wants to go back by clicking a hyperlink on that page then the second should appear in its previous state i.e. have showing the clicked value 29 and if he wants to go the first page then first page should keep and display its previous state with the searched data.
Page1>Page2>Page3
Page1<Page2<Page3
