WebMatrix :: Interesting Problem About @ And Extension Methods?
Oct 22, 2010
Note , that i'm new to c# so it might not be a problem.first , what is the exact meaning of @ in Razor ?does it mean WebPage.Response.Write ?next, i designed an extension method to WebPage ( by the way that is the coolest feature ever in c# )in my Razor code , to use it in a webpage , i must write @this.MyExtensionMethod() instead of @MyExtensionMethod().So why is it? because @this.MyExtensionMethod() and @MyExtensionMethod() should be the same ?
public static class PageExtensions { public static int GetUserId(this Page targetPage) { var user = Membership.GetUser(targetPage.User.Identity.Name); return (int)user.ProviderUserKey; } }
Now in a page I need to use this method in a static WebMethod, so I have added another 'extension method' to PageExtensions:
public static int GetUserId() { return (int)Membership.GetUser(HttpContext.Current.User.Identity.Name).ProviderUserKey; }
and I call it as follows in my WebMethod: PageExtensions.GetUserId()
I'm searching for some extension methods that helps programming in ASP.NET. Some functions to work on controls, validators, AJAX or programing in C# in general.It could be methods library or your own methods.Do you know any source of those methods (other than CodePlex - that is good source of generic extensions) especially for ASP.NET?
With regards to the Razor view engine, say I want to render Html.TextBoxFor<SomeModel>(i => i.Name), it doesn't seem that the inline syntax works as in:
@Html.TextBoxFor<SomeModel>(i => i.Name)
This doesn't seem to work because it interprets the generic as an HTML tag. I could use a code-block approach, but then what's the best approach to output the content? The HTML string returned from this method, do I response.write it, or is there a syntax for it, or what's the approach?
I am trying to create an extension to extend the HtmlTextbox methods to allow our developers to add onkeydown inline javascript to auto click a button with a name they specify.
I have a web site project using the .NET 2.0 Framework that I am working on in Visual Studio 2008. I am using a third-party DLL in my project. I have added a reference to the DLL in my project and I can use everything as expected, including a number of extension methods for certain objects. Intellisense sees these extension methods, and I am able to make use of them and I can build my project on my local machine without any errors.
However, when running my website on a production server, I get a Compilation Error saying that the extension method I am trying to use could not be found. I can use everything else in the DLL besides the extension methods on the production server.
This is my first exposure to extension methods and understand what they are, but I can't seem to figure out why I can't make use of these methods outside of my local machine.
In the previous version of our application we worked one we used MVC 1, so no area's. Following the ASP.NET MVC Best Practices by Kazi Manhur, I Created Extension methods of UrlHelper to generate your url from Route
Now with the new version, we are using MVC 2 and Areas. I was just wondering if one should implement it as before or have a new "best practice" regarding this emerged?
What I'm doing right now is:
1) Create a route in my area's route registration:
[Code]....
2) Creat an UrlHelper Extension method:
[Code]....
3) then just call it like this:
[Code]....
While typing this I started wondering what is the use of the ID you specify for the Area route..cant one just call the route using that?
Is it possible to do something like this inline in an ASPX page?
<%= Me.SomeExtensionMethod() %>
I can't seem to figure out how to get this to work properly. I'm receiving an error saying that "SomeExtensionMethod" is not a member of the current Page object. I've added the necessary <%@ Import Namespace="..." %> directive at the top of my page. This Does work in code-behind.This isn't vitally important, but it would be good to know how to do in the future.
We say that "GroupBy" and "OrderBy" methods from LINQ as Extension Methods.Then how about "variable.ToString()" and "string.Split()" menthods. Are these Extension methods.
I've found a Webmatrix help article that says MS Webmatrix "publishes the (SQL Server or MySQL) database by creating scripts that run in a database that has been created for you by your hosting provider." That is wonderful, except I can't get it to work when I'm trying to publish a MySQL database (backing wordpress) through FTP (my hosting provider does not support 'web deploy'). Again, no problem, since it is already documented that " FTP protocols cannot be used to publish MySQL database. " But this does not excuse Webmatrix from generating MySQL database install scripts for me. During the publishing step, no database install script is generated - at least that I can tell - and there is no manual option to create a database export / backup / install script.
In short, as Webmatrix goes, I'm dead in the water trying to get my database uploaded to my hosting provider. Does anyone know the trick to force Webmatrix to create the MySQL database install scripts on my local box? Once created, I can take-over the upload and install process.
I'm wondering if it is possible to include Microsoft.Data.Entity.CTP.dll reference to WebMatrix site and if the Compact edition of the database would support it? I'd kinda love use something like
code-first development in my WebMatrix project. I think is even easier than writing SQL-s into the code...
I started the Bakery site demo...everything runs fine on my local machine.When I publish the site to production server in w2k8r2+iis7.5 and with .net 4.0 (integrate) pool, my bakery apps not able to connect to the .sdf file.
Error I got is :
Connection string "bakery" was not found. Description: An unhandled exception occurred during the execution of the current web request. review the stack trace for more information about the error and where it originated in the code. Exception Details: System.InvalidOperationException: Connection string "bakery" was not found.
Source Error:
Line 2: Layout = "_SiteLayout.cshtml";
Line 3:
Line 4: FacebookSocialPlugins.Initialize("[xxx]", "[xxx]","bakery");
I struggle with publishing 2 databases from WebMatrix using WebDeploy. On Publish settings screen I specify 2 different connection strings, but on Publish Compatibility screen Database names in both destination connection strings are equal. When I return to settings screen, original value is replaced there as well.
How destination server connection strings are evaluated? Here are connection strings from the root web.config file, which are set by hidden parameters in my parameters.xml:
If I create two websites using the starter site template logging into one shows me logged into the other.
Here are the steps:
Create starter website called website1 Create starter website called website2 Run both websites in the same browser, firefox Register an account in website1 Log out of website1 Log back into website1 Refresh website2 and it shows my login name from website1 Has anyone else encountered this?
I'm often experiencing that keyboard shortcuts stops working in WebMatrix. This is very annoying as CTRL-S, CTRL-C, CTRL-V, etc. stops working, all of which are heavily used when programming. It's obviously hard to explain how to reproduce this, but I waswondering if someone knows a quick-fix?
There I was, happily coding webpages, when suddenly it wouldn't run them anymore. Now when I click run I get an error message that looks like this: Server Error in '/' Application.This type of page is not served. Description:The type of page you have requested is not served because it has been explicitly forbidden. The extension '.cshtml' may be incorrect. Please review the URL below and make sure that it is spelled correctly.
Requested URL: /quiz/intro.cshtml Version Information: Microsoft .NET Framework Version:4.0.30319; ASP.NET Version:4.0.30319.1
My hosting company states they support .net and razor. However after uploading my website made with webmatrix and razor *.cshtml pages. When i visit my website all i get is 404.17 error messages. As an testcase i decided to add an standard .aspx page. Visiting that page gives the same 404.17 error message :-( .
According to my webhoster my web.config is wrong. However that one is generated by webmatrix. Besides my *.cshtml *.aspx a lot of files and directories are added to the bin folder. What can i check and what should my hosting provider check. When using the check compatibility the asp.net version is shown as unknown? My hosting provider claims my site is running asp.net 4.0 in integrated mode and that should be enough.
