NET WebForms - Processing String Parameters Across All Pages On Site
Jun 25, 2010
Working on an ecommerce site which will be integrated with a 3rd party vendor--that vendor uses different identifiers for stores than we use internally (i.e. their store ABC123 is our 001-321). I'm researching the best approach to inspect incoming requests for reserved query-string parameters that indicate the request is using their identifiers and map the identifiers back to our identifiers (so if the request is example.com/&theirId=ABC123 I want to transform the request to example.com/&ourId=001-321). To do this mapping I need to inspect the provided ID, execute a lookup against the database or cache, and forward the request to the specified page--limiting the modifications to just the query-string parameters (other parameters will need to be maintained, as with the details of the HTTPHeader, etc). So far I'm researching a few different approaches: Implementing it in a base Page (which already does too much, but has the benefit of our Logging infrastructure and some other injected dependencies) Implementing it in an IHttpModule Using URL RewritingUsing URL Routing (looks like routing isn't what I want, feel free to offer insight if you think it still fits) Performance cost is a consideration: the actual number of times this translation will occur will be very small compared to the number of requests not requiring it--perhaps 1%. However for another integrated site we will perform this mapping on nearly every request--would a different approach be better suited to this scenario from the previous?

I am having a little difficulty trying to wrap my head around site structures. I have quite a large asp.net site, for which: Admins can see a user list, Each user can have many accounts, and for each account can have many items. I can picture this as a breadcrumb trail of editing a particular item. User List > Mr Bob > Accounts > BOB77 > Items > Item32 > Edit
User List = All the users Mr Bob = A user the administrator has selected from the User List Accounts = A list of the user's accounts 12BOB = The administrator has selected the account named 12BOB Items = A list of the items an account contains Item32 = The item that the administrator selected Edit = The action that the administrator wants to do. I can picture how this would look like if it was using ASP.NET MVC with the URL, but I am unsure how to map this out using Webforms, and in the physical filesystem.
This is what I have thought up about how I am guessing the physical structure would look like. Will this have to use session variables to achieve what I am trying to do?
/Users/User/Edit.aspx <- for editing a user
/Users/User/View.aspx <- for viewing a user
/Users/User/Accounts/Default.aspx <- for viewing all accounts
/Users/User/Accounts/Account/View.aspx <- for viewing an account
/Users/User/Accounts/Account/Edit.aspx <- for editing an account
/Users/User/Accounts/Account/Items/Default.aspx <- for viewing all items in an account
/Users/User/Accounts/Account/Items/Item/Edit.aspx <- for editing an item
Where can I read more about this kind of setup in a web application? Or, can someone point me in the direction of an available project that has this kind of layout?

I am executing a SSRS 2008 report from report manager so it opens in a web browser. Since it is a big report it takes some time for execution. During this time i get an error icon on the left bottom of the web browser and the execution stops. When I click open the error icon to see the details it says,
"Sys.WebForms.PageRequestManagerServerErrorException: An unknown error occurred while processing the request on the server. The status code returned from the server was: 12029."
The other relatively smaller reports are coming up successfully without any issue.
I am using SQL Server 2008 R2 64 bit ent. edition and the OS is Win Server 2003 64 bit SP 2.

I picked up a new-to-me client who had a site built in ASP.net (which I do not host).I converted the site to PHP, which worked fine.I want to set up redirects for all the pages he had in the old site (it was a small site, so there was only 8 pages).As an example, the ASP.net url for the Contact page was www.domain.com/Contact - it is now www.domain.com/Contact.php (and so on).
For 301 redirects from one PHP page to another I normally use the .htaccess file:
Options +FollowSymlinks
RewriteEngine on
#custom redirects
rewriterule OldPage.php http://www.domain.com/NewPage.php [R=301,L]
#end custom redirects
What can I do to redirect these ASP.net pages to the new PHP pages?They are all static pages with no dynamic content.

I need to know a way to process images in asp.net web pages. I need to be able to highlight a certain area of the image and put an image on top of the other, then save the image with those changes. So far everything I have seen requieres buy 3rd parties components which I can not afford, I need to develop this functionality using objects inside the .net framework, or a free component.

I have a requirement to show an Exit Popup on one of our processing pages. I am showing the exit popup by registering a client side javascript like
window.onbeforeunload = ShowExitPopUp();
The popup executes fine if you close the window, or try to type in a different URL. However the issue is that my processing page is also performing a "Response.Redirect" on the server side once the process completes. When response.redirect happens the exitpopup also shows up. Is there a way to have the exit popup not show up in that case?
Since my server side code is running through an UpdatePanel, so I have tried registering the following, in an attempt to remove ExitPopup from client side. However this doesn't work since server side redirection happens before end request.
Sys.WebForms.PageRequestManager.getInstance().add_endRequest(RemoveExitPopup);

What I'm looking for is a good sample of an open source WebForms site which contains demonstrations of some best practices, design patterns etc. Just want too look how experienced people apply their knowledge to build websites which can be shown to everybody without shame :)It would be good if the samples show these technologies: IoC, Entity Framework, Unit testing (with mocks), jQuery. The small samples which demonstrate the particular technology are useless as I've already examined many of them.My goal it to improve the existing huge WinForms application, so I'm not interested in ASP.NET MVC for the time being

With ASP.NET MVC it is pretty easy to integrate an IoC container to create the controllers. Is the same thing also possible with webforms to create the pages and controls and pass them any dependencies? If yes, where do I have to plug it in?

I am running an MVC 2 RC web appilcation with the majority of pages being webforms. (this is an ongoing conversionn to mvc).When people hit our domain at www.mydomain.com, I want the people to get the webform page MyDomainHome.aspx. This is the page specified in IIS as the default document. (I can't convert the home page to controller/view right now because it is very complicated etc.)
I also want the typical "{controller}/{action}/{id}" behavior. Is there a way to mix these together so people who have bookmarked my home page will still get there?
2. Also when I use the "{controller}/{action}/{id}" routing, my pages do not see the css or image folders that are specified in the master page.

In my Application_BeginRequest I have code that gets query string value ?c=FR or ?c=US and store it in cookies.Based on query string value I have either US or FR,locale is selected from locale table.If ?c=FR then locale will be fr-FR and if it is US then locale will be en-US.My code is below.
void Application_BeginRequest(object sender, EventArgs e)
{
LocalizationInfo loc = GetLocalizationInfo();
if (Request.Cookies["Localization"] == null)
Response.Cookies.Add(new HttpCookie("Localization"));
Response.Cookies["Localization"]["Country"] = loc.Country;
CultureInfo objCI = new CultureInfo(loc.Locale);
Thread.CurrentThread.CurrentCulture = objCI;
Thread.CurrentThread.CurrentUICulture = objCI;
}
public static LocalizationInfo GetLocalizationInfo()
{
string countryCode = "";
string sLocale = "";
if (HttpContext.Current.Response.Cookies["Localization"]["Country"] != null)
countryCode = HttpContext.Current.Response.Cookies["Localization"]["Country"];
if (!string.IsNullOrEmpty(HttpContext.Current.Request.QueryString["c"]))
countryCode = HttpContext.Current.Request.QueryString["c"];
if (countryCode == "")
countryCode = "US";
sLocale = HertzRent2Buy.DataProvider.ListData.GetLocale(countryCode);
LocalizationInfo ret = new LocalizationInfo();
ret.Country = countryCode;
ret.Locale = sLocale;
return ret;
}
public struct LocalizationInfo
{
public string Country;
public string Locale;
}
Now when I run the project and in query string I set [URL] then for the very first page(home page itself) it shows me French translation,but on subsequent page,that query string parameter ?c=FR is lost and hence it shows be English translation not French translation since it does not pickup French resx file.If I manually append ?c=FR in subsequent page then it shows the French translation.Is there is way how I can make that query stringparameter available in all pages.Structure is there to hold Country and locale variables. In all pages I am calling GetLocalizationInfo() method as follow
LocalizationInfo info = some.DataProvider.Globalization.GetLocalizationInfo();
And I create instance info to pass locale and country as parameter. GetProductDetails(id,info.Country,info.locale). why my query string parameters get lost on subsequent pages.

I have a site that is using Forms Auth. The client does not want the site session to expire at all for users. In the login page codebehind, the following code is used:
// user passed validation
FormsAuthentication.Initialize();
// grab the user's roles out of the database
String strRole = AssignRoles(UserName.Text);
// creates forms auth ticket with expiration date of 100 years from now and make it persistent
FormsAuthenticationTicket fat = new FormsAuthenticationTicket(1,
UserName.Text, DateTime.Now,
DateTime.Now.AddYears(100), true, strRole,
FormsAuthentication.FormsCookiePath);
// create a cookie and throw the ticket in there, set expiration date to 100 years from now
HttpCookie cookie = new HttpCookie(FormsAuthentication.FormsCookieName,
FormsAuthentication.Encrypt(fat)) { Expires = DateTime.Now.AddYears(100) };
// add the cookie to the response queue
Response.Cookies.Add(cookie);
Response.Redirect(FormsAuthentication.GetRedirectUrl(UserName.Text, false));
The web.config file auth section looks like this:
<authentication mode="Forms">
<forms name="APLOnlineCompliance" loginUrl="~/Login.aspx" defaultUrl="~/Course/CourseViewer.aspx" />
</authentication>
When I log into the site I do see the cookie correctly being sent to the browser and passed back up: However, when I walk away for 20 minutes or so, come back and try to do anything on the site, the login window reappears. This solution was working for a while on our servers - now it's back. The problem doesn't occur on my local dev box running Cassini in VS2008.

I have an asp.net2 WebForms project which worked fine, including referencing a dll compiled for .Net2.
Problem is that I have now recompiled the dll for .Net4 and have also 'upgraded' the VS2010 asp.net WebForms project to .Net4 and the asp.net WebForms application won't access the dll.
The first time the dll is called I get System.NullReferenceException: Object reference not set to an instance of an object.
The new dll is accessed by other WinForms applications OK.
Whatever the problem is, VS2010 freezes and I need to use Task Manager to close it down.

I got a a problem when using ToolkitScriptManager on masterPage with other webForm in SUbDirectory. Everytime I run other webform in the SubDirectory there was an Error "The ScriptManager must appear before any controls that need it". Then I added ToolkitScriptManager to that page I got another Error "Only one instance of a ScriptManager can be added to the page". hmmmm then I removed the ToolkitScriptManager from the MasterPage, It's worked for that page.
on that SubDirectory I had a webConfig file.
