I want to do something similar to what happens when you click an asp.net 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?

View 5 RepliesI 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?
View 2 RepliesI'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.
[Code]....
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.
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">

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:
[Code]....
Here is the handling code on page2 (rvProjectStatus being the ReportViewer control):
[Code]....
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.
I am having to create a GridView 100% in C# CodeBehind. I have it selecting a row and posting back using this code:
void dataGrid_ItemCreated(object sender, DataGridItemEventArgs e)
{
if (e.Item.ItemType == ListItemType.AlternatingItem ||
e.Item.ItemType == ListItemType.Item)
{
e.Item.Attributes.Add("onmouseover",
"this.style.backgroundColor='beige';this.style.cursor='pointer'");
e.Item.Attributes.Add("onmouseout",
"this.style.backgroundColor='#FFFFFF';");
e.Item.Attributes.Add("onclick", "javascript:__doPostBack" +
"('_ctl0$DataGrid1$_ctl" +
((Convert.ToInt32(e.Item.ItemIndex.ToString())) + 2) +
"$_ctl0','')");
}
}
This does post back but then how do I get the ID of the row the user clicked on?
I'd like to programmatically force a full page postback to occur after an event is fired by one of the child controls. I can't add any triggers to make this work so it will have to be done via code.
View 2 RepliesI have a controller:
<asp:Button OnClick="MyFunction" runat="server" />
I want to be able to call MyFunction without the page reloading. Is this possible with ajax or something?
If so how would I do it?
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?
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?
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?
View 1 RepliesI am trying to pass a value between two pages. However on my target page, the value is not found. My source page includes the following code.
Public ReadOnly Property SQLString() As String
Get
Return "SELECT * FROM City"
End Get
End Property
On my target aspx page I have included the following directive:
<%@ PreviousPageType VirtualPath="~/tools/SearchResults.aspx"%>
In the target page code behind I have included the following in the page load:
Me.Master.Page.PreviousPage.SQLString
However, Visual studio complains that, SQLString is not a member of System.Web.Ui.page. I must note I am useing master pages, and vaguely recall this causing an issue when accomplishing this in the past.
I am currently a beginner in asp.net i am currently watching msdn videos of "beginners developers learning" i am on the topic of application state so i got confused on a topic of "cross page postback" can anybody explain what that is
and another thing is "profile" object we use it in web.config file
1. what is cross page post back?
2. what is web.config file?
I'm at my wits end on this one looked/Searched/Played/Experimented and I need your help if you can.This page is going to be primarily used on a mobile device using Win Mobile 5 Need to Accomplish:Prevent Postback(serverside) of Page using JavaScript (Postback's slow down the page on mobile device)
[code]...
I use a Custom Validator (which validates on the server) and a button (it's PostbackUrl = "Page2.aspx").
When I press the button the browser show always Page2 without checking if the page is valid.
I'm trying to solve an issue in an elegant way. The problem at hand is I have 2 aspx pages (I'll call then Page1.aspx and Page2.aspx).
Page1.aspx contains an AJAX tab control with 3 tabs (I'll call the control Tab1). Page2.aspx also contains an AJAX control with 3 tabs (I'll call the control Tab2).
My question is, is there an elegant way to have a hyperlink on the second tab of the Tab1 control that links to the thrid tab on the Tab2 control? And, is there a way this linkage can be represented as a web address (example : http:\someserversomeappsomepage.aspx???TabControlIdentifier,???TabNumber.
The current methodology we are implementing is to pass the TabControlID and Tab number as querystring values and the set the focus in the codebehind of the page. But the only way I can think of to implement this across multiple pages is to have all the receiving pages implement the same overriding class that handles the focus issue.
I have 2 forms and i want to pass data to the second from the first. All i get is null value or nothing. In the first page i have :
