Trying To Do A Cross Page Postback And In The Target Page?
Jan 25, 2011
I am trying to do a cross page postback and in the target page I am trying to reference a usercontrol.this my user control class declaration.
[Code]....
this how I try to reference it in the target paget:
[Code]....
It will not compile and the problem I get or the error I get is: Error 79 Type 'BCWeed.GetADeal.UI.PurchaseCartAJAX' is not defined. D:ills systemBills Desktop estSocialmypurchase.aspx.vb 7 29 D:...Social
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 tring to send form values to a page from a user control. I included the user control in a master page.When i use page.previouspage it can not get value. is there any way to send form data to a page from a user control included in a master page?
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?
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?
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.
[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 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
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.
We're investigating if it's possible to have the following: A webpage with multiple 'folders' to which a user can drag & drop a files. It's meant to be used as an interface to upload scanned documents to an archive. For example, we would have page that states: 'Quotes', 'Invoices' & 'Misc'. Depending on the sort of document the user would drag & drop the file from the local file system to one of these three folders. It should then upload the file to the correct folder on the web server
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?
In my application a mail message send to particular recipeeient with msg body contains a hyper link.. when the recipent click on this link,it will redirect to another form(InternalForm.aspx)... bt when clicking the link error is occured,whuy its happening???? In InternalForm.aspx,page load portion access the link content(badgeno).. page load portion code of InternalForm.aspx is shown below:-
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)
I have created the form and html controls dynamically in the page load method of the page.
Like below :
Dim form As New HtmlForm Dim btnSubmit As New HtmlInputButton Dim txtQuery As New HtmlInputText form.Action = "User.aspx" form.Method = "POST" form.Name = "form1" txtQuery.Name = "user" txtQuery.Value = "john" btnSubmit.ID = "Submit" form.Controls.Add(txtQuery) form.Controls.Add(btnSubmit)
what I want is that without clikcing on the submit button it should navigate to the target page which is listed in the Action and post the data as well.
I am using IFrame in my ASP.NET pages. For the page that I am referencing in my IFrame, I have a gridview (I also have CommandField that referencing another asp.net page) and paging enabled.
I wanted to display a new page (outside of Iframe) when a user clicks on the commandfield in the gridview. In order to do that I set form's target to "_parent". This works fine (it open a new page outside of Iframe). Now, my problem is that when i click on the paging to go to next page in the gridview, it also opens the gridview outside of IFrame (which I dont want to happen). I want it to open within the Iframe.
I am creating a real estate website. The website has a search. When the user clicks on the button I am using CrossPagePostBack to get the information from the search and showing it in another page with the gridview.The problem is that when I want to search in the target page the crosspagepostback is still is fired and I do not want it to happens. I want the CrossPagePostBack to be executed jsut once . The code I am using is the following:
I have a parent page which has a button.When the button is clicked , it will bring user to the target page with variables from parent page.
My problem is my target page do not show up in the ie even though i have successfully pass the variable to the target page.By debugging, i can really see that i have already reach the target with all the variable from parent page is successfully read. BUT the target page don not show up in the ie, the page in the ie is still parent page.
Searched and couldn't find anything. I'm wrtiting an intranet application, and it creates links to see the original PO or Order for a given order number. Problem is that some of these orders were never put into the system electronically, so you get an error 400, no such page. Is there some way to programatically 'test' a link before sending the user to this error message?
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
I have an asp.net page "demo.aspx", that has a normal link called "Demo Link" which uses jQuery Thick box. The page that is wrapped inside the Thickbox is "target.aspx", that has a button "Demo Button" and a label.
If I click on the Demo Link, it show the "target.aspx" wrapped inside the Thickbox nicely. However, If I click on the "Demo Button", Thickbox is disappeared, "target.aspx" is not wrapped in Thickbox anymore, it is displayed like a normal asp.net page.
Here's the mark-up code of demo.aspx:
<a href="target.aspx?height=600&width=800" class="thickbox" title="">Testing Thickbox with Post-back</a>
Here's the code-behind of target.aspx:
Protected Sub btnDemo_Click(ByVal sender As Object, ByVal e As EventArgs) Handles btnDemo.Click lblDemo.Text = "Hello World!" End Sub
How do I keep target.aspx in the Thickbox after the post-back of itself?
I have a reports UI that allows users to select the reports that they want to run. I want to be able to display each selected report in its own window so the site does not navigate away from the reports UI. Is there a way to acomplish this? Maybe through the response object? UI Summary
The user selects the reports from a list then clicks the run button. On post back the selected reports are placed in a collection and redirects to a new blank page that will prompt for any parms, render the report, remove the report from the selected reports collection, and redirect back to the reports UI. If reports still exist in the selected reports collection it redirects to a new blank page until the collection is empty.
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.
