View 5 RepliesI 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'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 have an interesting issue I have racked my brain trying to find a solution to.
I have a site with a single master page. Part of that master page is a text field and button. They are not part of a content placeholder, they are simply part of the master page, itself, and are intended to allow people to search the site from any page on the site.
So, all search requests are routed to a search.aspx page, regardless. I am doing this by setting the PostBackUrl attribute of the button control to "search.aspx".
This all works great, except when I try to use this search capability from the search.aspx page, itself. I figure this is because I am using the Page.PreviousPage object and since a postback from the search.aspx page, itself will result in the Page.PreviousPage being Nothing, it is not performing the proper action.
Lets say I have a Web Application with a menu of products. When a user clicks a menu item, then create and display a dynamic set of controls in an Update Panel. I am currently doing this however the PostBack and recreation of controls is tedious and resource intensive.
Not sure about this but is it possible to build a webpage with controls on it, then display it in update panel or IFrame? Then on post back you wouldn't have to recreate everything all over again?
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?
View 5 RepliesI have vertical image slidslow using datalist. on left side i have vertical scrolling thumbnail items. if we click the thumbnail i need to load all
related fullsize images on right side of the thumbnail. i need to load all full size images without posting the page.coz if i post the page my thumbnail images position get reset and starts from begining. so i need to avoid this.
when any Button control is clicked generally it Postback the page to itself, and the same page is regenerated.This is the usual defination of postback in context of a Button Control. But my dear friends i am confused that what is the actual mechanism behind this.Okey say for definition the above statement is fine but believe me i not not getting the actual meaning.What is posting back the Page? What is Page in browser's context? There is only html markup, JavaScript and CSS codes in browser's page.These make up the html page. I think there is no any relation of this Browser's page with ASP.NET Page class. What does it mean that browser's content is posted back to the Page itself ?
View 1 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 have a problem of posting back in my website in some browsers. The Problem is: When I am uploading a file using file upload and button or posting page back on some event click after button click I am using:
ClientScript.RegisterClientScriptBlock(Me.GetType, "AddData", "alert('" & f_u_devideo.FileName & " Uploaded Successfully');", True)
But after that the page not not load again and a blank page comes in some browsers
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 have a button on my web form. When it is pressed, the event method for that button is called as it should be. However before the buttons method is called, the page load event is first called. Is there a way to prevent the page load event from being called when the button is pressed? I know about using !Page.IsPostback in the Page load method. However I wish to avoid posting back to the Page Load method altogether when this particular button is pressed.
View 6 RepliesI try to postback my page to the server using ctrl+Enter sequence.Without UpdatePanel it works well, but it works only two times inside updatepanel and then my control loses the focus. So I have some questions:
1. Why my control loses the focus if it is located inside updatepanel?
2. What is the best way to use ctrl+Enter sequence to post the page to the server?
Here is my code:

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?
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?
View 2 RepliesIs 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 have a master page and some child pages, i want that when i navigate the child forms, my should not post back, only the inner should navigate

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 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 2 RepliesI'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.
