i'm a beginner in asp.net and c# , i have a question :i have 2 pages :
1- localhost:12345/show_profile.aspx?id=35
1- localhost:12345/Edit_profile.aspx ( with save button )
i try to redirect 2nd page with parameter (?id=35 ) after button clicked with Delay 3 sec .i can assign the url to var with url.Ref function , and call it but with out delay.
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 am developing a web application in ASP.NET3.5 with C#. I also using Telerik RadAjax Control. When user click the menu then open the page with a new tab(Like web Browser).I want to create, when user back any previous tab(page) the will be show the previous data without loading 2nd time( like browser tab). Is it Possible ?
I am having problem while using onclick="javascript:history.back();" with Aspnet. In the first page i filled some data and click search button it show some results, i click on particular result for its details which navigate to the 2nd page but when i click on custom back button it refresh the page and all data set to initial values,when i use onclick="javascript:history.back();" I get nothing but the page displays "webpage has expired."
I am using an image button and on click of it i want to go to visited page.

It is going to previous page, but when i am in a page of some user details where the link is looks like - users.aspx?userid=25 and i visit some other page and click back(image button) i want to see the same serdetail page. How to track that.
i m having problem with logout code in asp.net with c#. this logout code should end session, disable browser's back button and and if somebody try to login by paste the url of any user account page.i used this code in login page
i am having three pages.first of all i fill register page it will redirected to next page .again i will fill this pageto move to next page. in this time i want to go back to previous page and want to edit content of that prevoius page.in this time i got one problem like"Violation of PRIMARY KEY constraint 'PK_Skills'. Cannot insert duplicate key in object 'dbo.Skills'. The statement has been terminated." how can i solve this problem.i am not having any primary key in my database.
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 an ASP.NET problem. When I press Back on Internet explorer, the previous page will be appeared. I need to prevent this page form appearing. How can I do this
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.
I have a gridview, getting data from sql server, there is an Edit link to get the detailed information for example, for a user from database.
this link open a new page with detailed information and when I click the updated button,I want to go back to the same page with that users informaton.
I set the page size to 10, it means I can see only 10 users per page,and if I click the edit link on page 25,and update the users info, I want to go back to page 25.
Should I use viewstate or gridview has any commnad to go back to the same page? the code is written in ASP.net C# sqlserver,
Code: protected void Page_Load(object sender, EventArgs e) { if (!Page.IsPostBack) //check if the webpage is loaded for the first time. { Session["PreviousPage"] = Request.UrlReferrer.ToString();//Saves the Previous page url in ViewState } }
And when the page was in "page2.aspx" using this code
if (Session["PreviousPage"] != null)//Check if the ViewState contains Previous page URL { Response.Redirect(Session["PreviousPage"].ToString());//Redirect to Previous page by retrieving the PreviousPage Url from ViewState. }
I encounter this issue.
