Cross Page Postback And Passing Info From Source To Destination Page

Feb 15, 2010

I have a FileUpload control in the Source page. On the Upload button handler, I read the file into memory (after doing some validations) and since it's always going to be a TXT file, I create a string that I need to pass to the Destination page. I thought of using Cross Page postback and set the PostBackUrl property of the upload button. But it appears that the breakpoint in the Upload button handler is never hit. It directly goes to the Page_Load in the Destination page. If I can't use Cross Page postback and don't want to use Session or the database, how do I pass this string from Source page to the Destination page?

Cross-page Postbacks And Back Again Retaining Data From Source Page?

Sep 17, 2010

Is it possible to use cross-page postbacks (or a similar method, perhaps Server.Transfer) to post form data (say, Data-set A) to a page, which then allows the user to add some additional information (say, Data-set B) and then postback to the original page the complete set of data (A+B) which then flows through the normal event execution process, similar to as if all data A+B was submitted on the original page to itself in a normal postback?

I don't want the second page to have any type knowledge of the original page, it just needs to supply two additional feeds and send the data on. This way different pages and controls could use this method for gaining additional data.

For example:

Page 1 could have a form with various text inputs, and two hidden fields Hidden1 + Hidden2 which are empty.

When the form on page 1 is submitted the user is presented with page 2, they complete that page and then all the form data from page 1 is posted back to page 1 but with the hidden fields 1 + 2 complete. Page 1 then has all the information it needs to complete.

I'm thinking that perhaps page 2 just needs to use PreviousPage and take its post data, add to it and then post it back to page 1, but as if it came from Page 1 and not Page 2. But I'm not sure if this is possible and ASP.NET might read this as tampered data?

Cross Page Postback From Codebehind?

Aug 16, 2010

I want to do something similar to what happens when you click an button that has a PostBackURL set. I've tried Server.Transfer but the URL doesn't change (which is something I want). Is there a better way to do this, or alternatively is there a way to make Server.Transfer display the correct URL?

Web Forms :: Simple Cross Page Postback Not Working?

Mar 13, 2011

I've been having trouble getting a postbackurl to work, so I tried to do a simple test between two pages and I still get the same thing.


That's all I have on Test1.aspx, yet no matter what I do it just postsback to itself. I can't get it to direct to Test2.aspx. I've tried LinkButton too.

I'm using VS2010 and the builtin webserver.

C# - Cross-Page PostBack Error When Posted From One Folder To Another?

Feb 18, 2011

I'm getting the 'Object reference not set to an instance of an object.' error on PreviousPage after using PostBackUrl.I created a simple test page to recreate the problem, however it worked fine, until I moved the source and destination pages into different folders. Is this the reason the PreviousPage object is null? how do I fix it?Both the folders the source and destination pages are in are in the root directory of the website.Source Page: /companies/test.aspx

<asp:Content runat="server" ID="Content" ContentPlaceHolderID="FullPage">
<asp:TextBox ID="Demo" runat="server"></asp:TextBox>
<asp:LinkButton ID="testlink" Text="test" runat="server" PostBackUrl="~/Documents/test2.aspx">

Web Forms :: Cross Page Postback - Unable To Read The Values From Page1?

Mar 25, 2010

I have a page (page1) with 4 controls that serve as the parameters for a report. The submit button does a cross page postback to another page (page2) that contains a ReportViewer control.Unfortunately, I cannot read the values from page1 once I get to page2. Here is the source to page1:


Here is the handling code on page2 (rvProjectStatus being the ReportViewer control):

In other situations I have passed such values in the query string and then assigned them to the parameter collection, no problem.Also, please note, I have tried using the @PreviousPageType directive to get at the types on page1, but have met with no success there either.

Passing Data Source Value To ASPX Page

Apr 17, 2016

I am new to programming and working on a school assignment. I have 2 display pages: default.aspx and DisplayTaxReturn.aspx. On default.aspx I have a list view where it uses data source to get the tax payer ID's from the server and I also have a details view where it displays the records associated to the tax payer.

When I click the View button on default.aspx it takes me to DisplayTaxReturn.aspx where it should display the tax payer ID and it's records that were displayed in default.aspx using label text fields.

My question is, how do I pass the values of the selected tax payer ID (datasource1 on default.aspx) to the DisplayTaxReturn.aspx page?

How To Raise Load Event On Previous Page With Cross Page Postbacks

Feb 21, 2010

I'm working on a wizard-like set of page, and I'm relying on cross page postbacks to navigate between them.

I need to be able to trigger the Load event on the previous page in order to save the form data for the page.

I've been told that for situations of this sort all I had to do is access the PreviousPage property in the destination page and this would trigger the load event of the previous page but for some reason this doesn't seem to be working.

Is there anything else I can do to explicitly trigger the load event on the previouspage if the PreviousPage property is not null?

Cross Page Posting Via HttpRequest || Page.PreviousPage?

I've been developing classic ASP pages at the job for the past five years and now we are moving to ASP.NET. I'm trying to understand how to get form field values from one page to another and it seems like there is more than one way to do it. In classic ASPI just called request.form collection and got the information. Which way is recommended in .net? Cross Page, Transfer, or HttpRequest?

txtSearchName.text = value
End Set
End Property

Web Forms :: Can Access The Route Data From The Destination Page

Sep 8, 2010

Looking at the v4 URL Routing it's easy to see how to access routing data from basically anywhere in the app.

Via: Page.RouteData.Values["blah"]

Unfortuantely the Route data always is blank by the time i hit the page on my v 3.5 implementation of routing. I was wondering if there was any way to either pass the route values to the final page so i can use them there - i really don't want additional logic in my handler file and i have loads of Routes and don't want many RouteHandlers.

Filling Out Page Info Based On Route To Page

Jul 19, 2010

I have 2 forms, one is filled out when a quote is supplied to a customer, if this quote is succesful a project is created and added to the database. On my form I have 2 buttons, one to simply submit the quote information to the database and I would like the second to, when clicked submit the information to the database and then use this information to fill out some of the fields on the Projects form. I have thought about doing this 2 ways:

I read you could use session variables to store the information, or since the data is already in the database, would it be posssible, that if the user has been directed to the projects page from the enquiries page that it fills in the information into the projects form?

Dec 6, 2010

look at this sample link address: ( [URL] if you view page source in browser, you can see that it shows data in XML format (usng xsl.?). I need to implement a simple web page like that. I think that web site uses XML XSL I'm going to implement a web application in which will use data stored in sql database (or xml database or web service) and show these information like other normal web sites but in xml format in nice UI (using xsl?).That Weather website is only a sample to show what i want to do (i will not use any data from that site, my application is different).My requirement is being able to view page source only in XML format.Now I'm clear that xsl is the solution for that, but considering to use this method in xml/xsl in dynamic pages) My Question? It is important for me to make the web page output in xml format(visible in xml format in page view source) but looks user friendly for users. can i do it in ?
