• What's the difference between $get and $find in JavaScript?

  - by RoboShop

  Hi, I'm a .NET programmer who've just started to learn more about client side scripting, and I was wondering sometimes you use $get('value') and $find('value') and I've discovered that these are just shortcuts for document.getElementById('value') and Sys.Application.findComponent('value'), respectively. However, I still don't understand: what is the difference between these two functions in JavaScript? What exactly are they looking up/retrieving when invoked? Thanks in advance.

• Compile aspx page "on the fly"

  - by user1122321

  I am trying to build an aspx page at runtime (by another aspx page which finally redirects to the new one). As far as I understand, aspx pages MUST be precompiled before a user can view them. In other words, the aspx page must be compiled to the DLL in the /bin folder. Is there a away to tell IIS, or to order it by VB.NET code, to compile a page before I am redirecting my user to the page? Any help would be greatly appriciated.

• DataContractJsonSerializer ReadObject Exception

  - by Dan Appleyard

  I am following the accepted answer of ASP.NET MVC How to pass JSON object from View to Controller as Parameter. Like the original question, I have a simple POCO. Everthing works fine for me up until the DataContractJsonSerializer.ReadObject method. I am getting the following exception: Expecting element 'root' from namespace ''.. Encountered 'None' with name '', namespace ''. Public Overrides Sub OnActionExecuting(ByVal filterContext As ActionExecutingContext) If filterContext.HttpContext.Request.ContentType.Contains("application/json") Then Dim s As System.IO.Stream = filterContext.HttpContext.Request.InputStream Dim o = New DataContractJsonSerializer(RootType).ReadObject(s) filterContext.ActionParameters(Param) = o Else Dim xmlRoot = XElement.Load(New StreamReader(filterContext.HttpContext.Request.InputStream, filterContext.HttpContext.Request.ContentEncoding)) Dim o As Object = New XmlSerializer(RootType).Deserialize(xmlRoot.CreateReader) filterContext.ActionParameters(Param) = o End If End Sub Any ideas? Thanks

• page loads twice in Google chrome

  - by Cristian Boariu

  Hi guys, Does anyone have any problems with Page_Load being executed twice in Google Chrome? It's a short question, i do not know what else to explain... I have a simple asp.net page and in Firefox and IE all it's working fine. But in Chrome the Page_Load is fired twice... Anyone has any ideas why? Later EDIT: - what is strange is that i have 4 repeaters... binded with random values. The random methods are twice fired (because of page loaded twice) but the repeaters takes the INITIALLY values...so, the 2nd post back is somehow raised after the rendering step. 3rd edit: It happens ONLY at the refresh!

• Anybody using Orchard CMS?

  - by Clarence Klopfstein

  This question is a bit subjective in nature, but I am unsure if there is a better place to ask this in the family of sites. Is anybody using the new Orchard CMS on a public facing site? For those that don't know, Orchard is basically the replacement for Oxite. It is an ASP.NET MVC based CMS. I've pulled it down and compiled it, but it seems pretty far away from being used on an actual site. If you are using it, would love to know.

• Telerik RadComboBox in a RadGrid Client Side Validation Problem

  - by infocyde

  Hi all, I'm using the Telerik ASP.net control suite (2008 Q3 I believe, can't upgrade yet). I've got a radcombobox in a Radgrid control (in a GridTemplateColumn's Edit template). If functions ok, but I've got some client side validation on other controls on the grid (that appear to be working without errors). For some reason after the client side validation happens, the combo box stops functioning. No visible js errors, the thing just dies. Anyone seen this and have fix? Google has failed me. Thanks for your help.

• C# Open Source/Free Social Networking SDK

  - by Nix

  I am currently gathering some technology requirements for a site that will be a social network based. I don't want to re-invent the wheel so i am looking for some type of SDK or collection of tools that can provide me with a way of creating/managing a social network. I understand that no framework will probably fit my exact needs so I am also looking for a flexible/extendable framework. An example extension point would be allowing the user to provide sub networks, maybe a global network that could be sub classified as work and friends. Beyond that it would also be nice to somehow be able to import contacts from other networking sites (Facebook, Linked In, etc). My current technology suite will more than likely consist of the following: IIS 7.0 WCF Data Services SQL Server 2006 ASP.NET front end. So my two questions are 1) C# Open Source Social Network SDK 2) C# Open Source Social Netowrk APIs (facebook, linked in, etc) If there is any more information you may need please let me know.

• jQuery AJAX see redirect as status 200 not 302?

  - by Max Fraser

  I am using jQuery and the jQuery.form plugin to submit my form (also using ASP.Net MVC). Problem is the user is in a section of the site that uses forms authentication and if their auth cookie expires during their time on the page instead of getting back a status of 302, which would be the redirect to the login page, I still get 200? In FireBug I see the 302 Found and then my login page is served next as a 200 which is the status code sent back to my Ajax call. How do I detect that they have been logged out if I never see the 302 sent back to the jQuery form plugin?

• FSharp.Core.sigdata not found alongside FSharp.Core

  - by Mauricio Scheffer

  I'm trying to use F# for an ASP.NET MVC application. One my controller actions sends an F# list to the view, so I write: <%@ Page Language="C#" Inherits="ViewPage<FSharpList<int>>" %> Of course, for this to work, I have to add Microsoft.FSharp.Collections to the namespaces element in my web.config: <add namespace="Microsoft.FSharp.Collections"/> and add a reference to FSharp.Core, in the assemblies element: <add assembly="FSharp.Core, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a"/> As soon as I add this assembly reference, every view (whether it uses an F# type or not) fails with this error: error FS1221: FSharp.Core.sigdata not found alongside FSharp.Core I can work around this by not having any F# specific types in my views, but what's the reason for this error? Also, where's FSharp.Core.sigdata ? It's not in my GAC and I can't find it anywhere.

• Problems deploying MVC2 - Could not load type 'System.Web.Mvc.UrlParameter'

  - by Evgeny

  Hi Everyone, I have problems deploying MVC2 application to my hosting. It shows the following error: Could not load type 'System.Web.Mvc.UrlParameter' from assembly 'System.Web.Mvc, Version=2.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35'. It looks like it does not understand the new "optional URL parameters" feature of MVC2. This is just a simple test application I created with "New Project" wizard in VWD 2008. It works ok localy both in IIS and Visual Studio web servers. MVC1 web sites are working ok on the hosting server. I've contacted the hosting support and they installed MVC2 but the problem still exists. The web site is working in ASP.NET 2.0 integrated pipeline mode. Does anyone know why it is happening? Thank you!

• MVC repository pattern design decision

  - by bradjive

  I have an asp .net MVC application and recently started implementing the repository pattern with a service validation layer, much like this. I've been creating one repository/service for each model that I create. Is this overkill? Instead, should I create one repository/service for each logical business area that provides CRUD for many different models? To me, it seems like I'm either cluttering the project tree with many files or cluttering a class with many methods. 6 one way half dozen the other. Can you think of any good arguments either way?

• jQuery button click refresh of jqGrid only firing once

  - by The Matt

  I have the following jQuery code which I'm using to populate a jqGrid. It works perfectly posting to my ASP.NET MVC page on the first click of the button. My problem is, any other clicks past the first it seems to run through the jquery code when clicking the button but it never makes it to the POST page. Any ideas why? <script type="text/javascript"> $(document).ready(function() { $('#btnSubmit').click(function() { /* Refreshes the grid */ $("#list").jqGrid({ /* The controller action to get the grid data from */ url: '/CRA/AddPart', data: { partNumber: "123"}, datatype: 'json', mtype: 'GET', /* Define the headers on the grid */ colNames: ['col1', 'col2', 'col3', 'col4'], /* Define what fields the row columns come from */ colModel: [ { name: 'col1', index: 'invid', width: 290 }, { name: 'col2', index: 'invdate', width: 290 }, { name: 'col3', index: 'amount', width: 290, align: 'right' }, { name: 'col4', index: 'tax', width: 290, align: 'right'}], height: 'auto', rowNum: 10, rowList: [10, 20, 30], sortname: 'id', sortorder: "desc", viewrecords: true, imgpath: '../../Scripts/jgrid/themes/steel/images', caption: 'Core Return Authorization Contents:', cellEdit: true }); }); }); </script>

• Visual studio 2010 remote debugging is very slow (across domains, over vpn)

  - by alex

  Overall debugging works, but each step through code takes dosens of seconds. I've already closed all additional windows like stack trace,watches,autos; deleted all breakpoints. server and dev machine are located in different domains, so i set up local user on both, with matching password. remote debugger is running as service. looking at security log, I found quite a lot of entries about remote debugging account logging in (record about every minute). Any suggestions on how i can speed up remote debugging? dev computer: quad core, 8 Gb mem, win 7 x64 , visual studio 2010 ultimate target server: asp.net website , 2xdual core xeon, 2Gb mem, remote debugger 2010 communication channel: vpn , 5 mbit , latency about 20ms. (seems that debbugging never uses more than 20 kb/s)

• Sending a Soap Header with a WSDL Soap Request with PHP

  - by Josh Smeaton

  I'm extremely new to SOAP and I'm trying to implement a quick test client in PHP that consumes a ASP.NET web service. The web service relies on a Soap Header that contains authorization parameters. Is it possible to send the auth header along with a soap request when using WSDL? My code: php $service = new SoapClient("http://localhost:16840/CTI.ConfigStack.WS/ATeamService.asmx?WSDL"); $service->AddPendingUsers($users, 3); // Example webservice [SoapHeader("AuthorisationHeader")] [WebMethod] public void AddPendingUsers(List<PendingUser> users, int templateUserId) { ateamService.AddPendingUsers(users, templateUserId, AuthorisationHeader.UserId); } How would the auth header be passed in this context? Or will I need to do a low lever __soapCall() to pass in the header? Also, am I invoking the correct soap call within PHP?

• Repository Pattern and Entity Framework.

  - by vitorcast

  Hi people, I want to make an implementation with repository pattern with ASP.NET MVC 2 and Entity Framework but I have had some issues in the process. First of all, I have 2 entities that has a relationship between them, like Order and Product. When I generate my dbml file it gaves me a class Order with a property that map a "ProductSet" and one class Product with a property that map wich Order that Product relates itself. So I create my Repository pattern like IReporitory with the basic CRUD operations and inside my controllers I implement the ProductRepository or OrderRepository. The problem occurs when I try to create Product and have to assign my Order on it, like ProductOne.Order = _orderRepository.Find(orderId); That operation gave me some strange behavior and I can't find out what is wrong with it. Thanks for the help.
