Just trying to get to grips with the Razor syntax - i had noticed that by default new views will have the following code in them;
@{
ViewBag.Title = "Index";
}
<h2>Index</h2>
And the _layout.cshtml file accesses this variable
<title>@ViewBag.Title</title>
Is it just as simple as "the layout page gets fired last" or is there a firmer definition?
I've been writing an app using the awesome new Razor view engine and for the most part, things have been great.
One issue I keep running into, however, is that if I should happen to write invalid code, such as referencing a null property or even a non existent property, rather than throwing an error, something happens in the background that causes the browser to wait and wait and wait and if I do not cancel the browser's request quick enough, IIS will simply hang.
It seems as if it enters some sort of loop. CPU usage goes up (though not terribly high) and restarting IIS via either GUI or iisreset command seems to take abnormally long (presumably while it waits for the process to safely shutdown).
This also happens for other invalid code scenarios such as failing to close a code block with a closing brace.
MSDN got a page showing in which order ASP.Net global.asax methods are invoked. I can't seem to find it, anyone got a linkAre there a similar page, but for ASP.Net MVC (including in which order all controller methods are invoked like OnActionExecuting, OnAuthorization etc)?

I manage a large asp.net site which has previously been converted from static html site to asp.net. For several reasons (mainly SEO) we decided not to rename all the files to .aspx back when we originally converted the site. This was very easy to do by simply adding the buildProvider and httpHandler to the web.config.
<buildProviders>
<add extension=".html" type="System.Web.Compilation.PageBuildProvider"/>
</buildProviders>
<httpHandlers>
<add path="*.html" verb="*" type="System.Web.UI.PageHandlerFactory"/>
</httpHandlers>
Now I am upgrading the site to use Asp.net WebPages with Razor cshtml files. I can rename all the files if necessary, and use url rewriting to make the urls stay the same, however it would be much easier if I could just configure the web.config to tell it to parse .html files as if they were .cshtml. I have searched around quite a bit, and could not find anything equivalent to the PageHandlerFactory for razor pages. It appears as though it is just an internal mechanism in the .net 4.0 ISAPI handler.
The site is currently running on Windows 2003 server and IIS 6. We will be upgrading to 2008/IIS 7.5 in the near future, but I'd prefer not to wait for that. Is there any way to get the .html files to be parsed by razor as if they were .cshtml files?
I have a requirement where I want to trace what file is being processed by .net runtime. I mean if it is processing usercontrol x.ascx then it should return the whole path of that, and if it is processing usercontrol y.ascx it should return that. There are some candidates properties. equest.AppRelativeCurrentExecutionFilePathor TemplateControl.AppRelativeVirtualPath. Can somebody help me with this, or is there any other property that can give me the path.
View 1 RepliesLet's imaging there are 2 pages on the web site: quick and slow. Requests to slow page are executed for a 1 minute, request to quick 5 seconds.Whole my development career I thought that if 1st started request is slow: he will do a (synchronous) call to DB... wait answer... If during this time request to quick page will be done, this request will be processed while system is waiting for response from DB.[URL] One instance of the HttpApplication class is used to process many requests in its lifetime. However, it can process only one request at a time. Thus, member variables can be used to store per-request data.Does it mean that my original thoughts are wrong?Could you please clarify what they mean? I am pretty sure that thing are as I expect...
View 2 RepliesI have a page (i.e. page1.aspx) that a user will select from the record and it will press on the delete button. And it will redirect on another page (i.e. page2.aspx). On page2.aspx, I wrote my query for example
Code:
DELETE FROM items WHERE item_id=2 how may I know if the query was successfully processed because I have to redirect again on the first page.
I am using HTTP load testing tool to stress test my asp.net 2.0 application. I faced problem that, when I have 1 user access to the system (currently only test on login.aspx), it is very fast ~ 1-2 secs. However, when I run with 10 virtual users at the same time, it takes 10-12 secs for each.
User Response Time (s)
1 10.12
2 10.22
3 11.00
...
10 12.78
My question is, why ALL of them also takes 10-12 secs? Is it normal? I was thinking that should be some users take 2-3 secs and some 5-6 secs and etc.
I have a page that has a bunch of user controls. I would like to be able to see which user controls are performing badly. I would like to be able to see this in the trace. any way to do this.

View 2 RepliesI have two table Order and Order Detail.
What i need is i need to bind last 10 Order in Gridview/details view with paging, and the same order detail also fetch from database and shown in another gridview.. if user click any oderNo in first Gridview/DetailView then i need to show Respective order detail in anther gridview..
without postback coz we already fetch 10 order with orderdetails from the database..and if user click next 10 orderNo using paging then again we need to load 10 orderNo with respective orderdeatils from database like this going on....as well as let me know how to take print of particular oder and order detail....?
From my testing, it appears that the order of parameters for the UpdateParameters must match both the order of the bound fields on the form (asp:Formview), and the order of the parameters in the UpdateCommand. Is that correct? If so, why do the parameters have names if all that matters is the order? I tried both asp:ControlParameter and asp:Parameter. Maybe the more relevant question is why aren't the names used instead of the order, particularly for the form order?
So, given I display the Identity field (CID), and need that for the update, I cannot get the update to work without including it in the UpdateCommand. Of course, since it is an autonumber field in Access, I cannot actually set it. So, I had to add another field to the db (lngUpdateCID) that I could set. That can't be how it has to be done, but I could not figure out another way to do this.
The relevant code is below:

i'm developing a site using VS2010 and with my windows vista busniness OS. i used the default VS2010 wizard for new web application to create it. included a folder in the root directory and created new aspx pages to derive from the master page in the root directory of my site. everything shows on the new pages except the jpeg image logo in the master page. But other aspx pages i created in the root directory shows every thing fine.
View 1 RepliesPage B - loads slowly and needs to do some CPU-intensive operations on the web server.
I noticed that when someone is loading Page B, then Page A also loads slowly. This is even worse if multiple users are loading Page B at the same time. Page A won't finish loading until Page B is done.
Is there a best practice for making sure that Page A can still load quickly? Maybe a config setting or IIS setting that I need to change from its default? With 2 users loading Page B at the same time, the web server CPU usage only gets to 30% so I suspect it might be something I can tweak with the settings.
Currently I'm doing common functionality required throughout my site inside of my masterpage. What I want to do is move this functionality to a BaseClass so All my pages inherit from the Base Class.

View 5 RepliesIn 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 few pages that are completely static. They only change at build time. But they are expensive to create. For the ones that are kind of expensive to create, I cache them for very long times using the ASP.NET output caching. But for one page, I really want it cached forever and ever or until the the next build.
What is the most expedient way to make this happen? Is there a build in feature that achieves this or a 3rd party tool?
(yeah, for the moment I plan to do the "view source" and copy paste thing, which isn't a very elegant build step)
I have added a jquey menu in my master page its working fine for those asp.net pages which are at the same level as master page.
But this menu isn't working at all for all of those page which aur in Editor's and Admin's folder. In these pages menu is displaying as simple html menu and unfortunately no jquery effect is shown on it.
I'm very confused why this menu isn't working for the pages which are in a seprate folder while the master page is added at the root level outside of all these folders.
How can we add titles to each content pages which inherits from mater pages in asp.net?
