Why Is The Form Action Attribute Empty On Production Server
Apr 12, 2010
After deploying a ASP.NET WebForms application to a production server some of the ajax calls has stopped working for me. After some debugging I found out that the following statement (in the internal client-method WebForm_DoCallback) was causing the problem:
xmlRequest.open("POST", action, true);
The problem seemed to be that the action-variable was empty so after checking the rendered html I found out that the form-tag rendered on the production server looks like:
<form method="post" action="" id="Form1">
However, on my developer machine I get the following:
So, why would the action-attibute render on my dev.machine but not on the production server? This seems to be the case only for one specific web form, when I look on other pages the action-attribute renders correctly.
I have a button that does a postback to server then back to client and finally to the action attribute of the form element.When the page post back to the client the onload <script>document.frm.submit()</script> finally submits the form to the action attribute of the form.I would like to eliminate the unnessasay post back to the client.Below is the code the runs on the server.
I have a form action in an ASCX page set to an external URL
<form id="fLoginForm" runat="server" action="http://external.url" method="post" defaultbutton="bSignIn"> Inside there is a standard ASP linkbutton <asp:LinkButton CssClass="btn" ID="bSignIn" runat="server" Text="Sign In" OnClick="bSignIn_Click" />
The event "bSignin_Click" never gets fired when I have ction="http://external.url" set on the form tag. However when I remove the action, it works as expected. I thought for runat='server' forms, the form would always post back? I need to read the URL from the action attrib and then redirect to it with some hidden input values also in the page.
I'm making a urlrewriter component and I need to set the action attribute of the html form tag to the virtual url. This is easy to do in the page that has that tag but I want to do it from within the component. I have a class called UrlRewriterModule which inherits from IHttpModule and in the OnPagePreInit method I run the code:
[Code]....
This actually works... but... this code presumes that I have a page which has a masterpage where the form tag is located.
How can this be done so that it will work with any hierarchy? I want to access the form tag wherever it is located.
I have an app I am transitioning to MVC3 to see what the upgrade path is essentially. I've hit a snag. I believe I've run into a change that may be due to the changes for Dependency Injection in action filter attributes, but I have been unable to track down the cause, and the "correct" solution.This project uses StructureMap and NHibernate. The NHibernate session is started at the beginning of each request, and ends at the end of each request, thanks to a small module. This is just to give an idea of the stack involved...o I have a few custom Authorize attributes (Inheriting from AuthorizeAttribute) that perform some more complicated authorization logic for specific actions that they decorate. Part of their functionality involves using two repositories which they must either (a) have injected, or (b) get from the StructureMap ObjectFactory themselves. In MVC2 I was using option b, so that the CONSTRUCTOR of the attribute looked like this:
[Code]....
This worked fine, as in MVC2 the constructor was called each time the attribute was evaluated. This BREAKS in MVC3, where it would appear that this is no longer the case. Due to this apparent change, the FIRST time this attribute is evaluated, it runs fine, but each subsequent time, any calls in the repositories fails because it claims the NHibernate Session object hasn't been started! The reason being, as far as I can tell, that the CustomAuthorizeAttribute is created once, and then held in whatever state it exists in at that point for the lifetime of the application... Which means that the dependencies inside of it (Which SHOULD go out of scope at the end of each request, and be reinstantiated / fetched at the beginning of subsequent requests), are instead persisting with it becoming stale after the first evaluation.After banging my head against the desk for a few hours, I realized that simply moving these calls to the ObjectFactory into the AutorizeCore method made everything work again.Now, all of this was of course, a hack, because there wasn't a good easy to do real dependency injection into attributes in MVC2. I hear that is changed in MVC3, and I am wondering if this behavior is in response this change, and if so, what do I need to do to make this work?
I have a web form called default.aspx which has a form with user information. In addition to this, I have an iFrame on the same page that displays a page Secondary-Form.aspx that has a few additional dynamic data fields. I need to do two things.
1. I need to pass the parent form data in real time to the iFrame page to refresh its content and modify it's fields accordingly. Example: If the user submits their Vehicle Choice as Car on parent form, the form item in iFrame will display a radio button that says Honda, and if the user submits their Vehicle Choice as MotorCycle in the parent page, the iFrame will display Harley Davidson as the radio button choice
2. The submit button is on the parent page. I want both pieces of this information (from the parent page, as well as iFrame selection) to be passed to a server side ASPX page to process this information.the default.aspx and Secondary-Form.aspx files are located on different domains.
I have a hidden TextBox control on my page that updates a span tag on the keyup event using jQuery. When the page is posted back to the server, the innerHTML attribute is empty.
How do I get the value that was set during the keyup event?
I am facing challenge of changing action attribute of html form tag. As my application is on shared hosting (medium trust) environment of godaddy server, I cannot use reflection to get control adapter of html tag page. So, I cannot use the following code in my Url Rewriting module.
[Code]....
Is there any otherway to implement the same functionality without reflection?
Problem: designer.cs is not regenerated by visual studio 2008. This concerns both web forms and master pages.
The only error or warning I can find is: Generation of designer file failed: The 'src' attribute cannot be an empty string. Line 1, Column 0
But the strangest thing is, it shows the warning always in the last page, I had or have open.
I know I'm not the only with the regeneration problem, I tried several solutions:
Deleting the *.designer.cs file. Doesn't work for me, the above warning become's an error when I try to rebuild the solutions or when try to covert to web application.
Reinstalled sp1 didn't work either.
Refresh in de designer view, getting the above warning...
I have sucessfully created a .aspx form with submit button feature that publishes correctly in my development environment running localhost. I am now attempting to move this form into my public website and it will not render in the public environment, only returning the code of the form.
I have a site master page which has 2 forms on it like so
[Code]....
But when I click the submit button in the second form on the page it submits the values from the first form to my controller and will run both controller actions. What I want is each form to submit only its own data is there some special way to do this?
I have been struggling with this issue recently, i am sure i can get it answered here.
I have deployed my code on godady hosting server which has IIS 7.0 and asp.net version 4.0.
My page when accessed in local desktop does generates form name attribute for form tag but when same code when accessed on Godaddy hosting server it does not.
I have some code which is rendering some custom attributes of Hidden Control (without runat=server).
Something like,
And I have a lot of these hidden elements on my form.
When I submit the form, I am looping through a set of ids, say 1200 to 1250, so I will read controls based on that, and also hidden with Request.Form["hdn "]
Now problem is, as we know we get value attribute from form when we do Request.Form["id"] for hidden, I want to read my custom attributes from hidden element. Is there any way? Note that, I can not touch the rendering part here.
as you see article query string will have the id of the article. in my new mvc app, I wiil display my blogs on www.example.com/40
here, 40 is the id of the article.t the search engines have my current url and if I upgrade my app to mvc app, the links will be broken. so what is the best way of mapping those url in an mvc app.
I'm trying to write some code that uploads files to Amazon S3. In the example I'm given, the form posts to a URL on Amazon. How do I set the action for my form to Amazon? Here's the code Amazon posted in their documentation: [Code]....

I have created my site using ASP.NET Personal Starter Kits 3.5. I use Visual Studio 2008 only . .with its built-in SQL Server (2005 Express) ... my database in App_Data is ASPNETDB.MDF ...
I have created some of my tables also ....in ASPNETDB ..
In my local PC the site was running fine ...
But when I publish my site on production server it doesn't work and shows the following error
Notes: The current error page you are seeing can be replaced by a custom error page by modifying the "defaultRedirect" attribute of the application's configuration tag to point to a custom error page URL.
My hosting provider gave me the connection string to connect to the SQL Server 2005 but it doesn't work...
I don't understand why my site was running fine using the production SQL Server 2005 in my local PC when I include ASPNETDB.MDF file in App_Data in my local pc only ..if I remove file ASPNETDB.MDF from App_Data of my local pc ... the site stops working ...
Can anybody tell em how to fix this ... !! I am very tensed since last 3-4 days
I create a dynamic dropdownlist to select several values, in developer server it's everything ok but in production server, when the postback happens lost the selected value.
how to transfer my data from devlopment server to production server ,i have already records exist in my database if i go for script then how can i transfor record in script i can transfor only table ,procedure and views.I am using SqlServer 2005.
I have a URL /products/search where Products is the controller and Search is the action. This url contains a search form whose action attribute is (and should always be) /products/search eg;
This works ok until I introduce paging in the search results. For example if I search for "t" I get a paged list. So on page 2 my url looks like this :
/products/search/t/2
It shows page 2 of the result set for the search "t". The problem is that the form action is now also /products/search/t/2. I want the form to always post to /products/search.
My routes are :routes.MapRoute( "Products search", "products/search/{query}/{page}", new { controller = "Products", action = "Search", query = "", page = 1 }); routes.MapRoute( "Default", "{controller}/{action}/{id}", new { controller = "Home", action = "Index", id = "" });
How can I force Html.BeginForm(), or more specifically Url.Action( "Search", "Products"), to ignore the /query/page in the url?
