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 using VS2010 and the builtin webserver.
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 am trying to make a simple composite control - just a label and textbox - but the postback isn't being picked up by the control.I haven't implemented IPostBackDataHandler as according to this its not necessary - the TextBox control should tie in automagically. A composite control that includes a TextBox need not worry about postbacks, as the embedded control will work it out with ASP.NET automatically.
class TestControl : WebControl
{
Label _label;

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 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 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'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">

EDIT: At first I thought it wasn't working cross domain at all, now I realize it only works in IE. I'm using jQuery to call a web service (ASP.NET .axmx), and trying to us jsonp so that I can call it across different sites. Right now it is working ONLY in IE, but not in Firefox, Chrome, Safari. Also, in IE, a dialog pops up warning "This page is accessing information that is not under its control..."
$.ajax({
type: "POST",
[URL],
dataType: "jsonp",
success: function(data) {
alert(data.prop1);
},
error: function(XMLHttpRequest, textStatus, errorThrown) {
alert(XMLHttpRequest.status + " " + textStatus + " " + errorThrown);
}
});
And the server code is:
[ScriptService]
public class TestService : System.Web.Services.WebService{
[WebMethod]
[ScriptMethod(ResponseFormat = ResponseFormat.Json)]
public void HelloWorld() {
string jsoncallback = HttpContext.Current.Request["jsonp"];
var response = string.Format("{0}({1});", jsoncallback, @"{'prop1' : '" + DateTime.Now.ToString() + "'}");
HttpContext.Current.Response.Write(response);
}
}
I am making a asynchronous request to different server for some data using jquery. It works fine in IE, but doesn't work in FireFox and Chrome, when it reaches the code where the request to other server is made, it freezes there and a blank page is shown. If I remove that piece of code, the ajax works fine.
Also, when I place a breakpoint at document.ready, the breakpoint is hit when debugging using IE, but it's not hit when debugging using FireFox.
Following is the JQuery I am using
jQuery(document).ready(function ($) {
$('.tabs a, .tabs span').livequery('click', function () {[code]....

When a new item is inserted I want to show a message like "Successful" for 3 seconds and then redirect to main page. For that purpose I used timer control. It works fine in IE but not in firefox. Below is the tick method:
protected void UpdateTimer_Tick(object sender, EventArgs e)
{
UpdateTimer.Enabled = false;
lbl_Result.Visible = false;
if (lbl_Result.CssClass == "successMessage")
{
lbl_Result.CssClass == "failureMessage"
Response.Redirect("~/Admin/ManageSportCategories.aspx");
}
}
In firefox, it continuously refresh pages, timer never gets disabled. What should I do?
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 have a simple js function that counts down the characters in a text box, and it works in every browser EXCEPT Firefox (3.6.6). I've tried changing some syntax, but nothing has worked so far.

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 have a simple web service that isn't working with a standard jQuery call. The code is below. The jQuery will execute and succeed, but on debugging, the service argument is always null. I've had it separated as 4 string params in a json string and that didn't work either. I must be missing something on the config side, but I can tell what it is.

I have a simple .aspx page. Where I need to connect to sql server 2008 and show the records on the page in a gridviewcontrol. It will have Edit button on the gridview control. I am getting some weird message about the connection string.
Error message is:
