  • ASP.NET MVC3 - Bug using Javascript

    - by ebb
    Hey there, I'm trying to use Ajax.BeginForm() to POST A Json result from my controller (I'm using MVC3). When the Json result is called it should be sent to a javascript function and extract the object using "var myObject = content.get_response().get_object();", However it just throws a "Microsoft JScript runtime error: Object doesn't support this property or method" when trying to invoke the Ajax POST. My code: Controller: [HttpPost] public ActionResult Index(string message) { return Json(new { Success = true, Message = message }); } View: <!DOCTYPE html> <html> <head> <script src="@Url.Content("~/Scripts/jquery-1.4.4.min.js")" type="text/javascript"></script> <script src="@Url.Content("~/Scripts/jquery.unobtrusive-ajax.js")" type="text/javascript"></script> <script src="@Url.Content("~/Scripts/MicrosoftAjax.js")" type="text/javascript"></script> <script src="@Url.Content("~/Scripts/MicrosoftMvcAjax.js")" type="text/javascript"></script> <script type="text/javascript"> function JsonAdd_OnComplete(mycontext) { var myObject = mycontext.get_response().get_object(); alert(mycontext.Message); } </script> </head> <body> <div> @using(Ajax.BeginForm("Index", "Home", new AjaxOptions() { HttpMethod = "POST", OnComplete = "JsonAdd_OnComplete" })) { @Html.TextBox("message") <input type="submit" value="SUBMIT" /> } </div> </body> </html> The strange thing is that the exactly same code works in MVC2 - Is this a bug, or have I forgot something? Thanks in advance.

  • How to seralize only some properties in .Net?

    - by Beta033
    This is for a web project so i have several classes that inherit from Web.UI. I only want to serialize very particular properties (basically, only local properties) I'm aware of the XMLIgnore property that can be placed on a property to ignore items, but this won't work in my context since that would require modifying a bunch of stuff that i really don't want to modify (and probably can't). So how do i tell the xml serializer to ignore everything except for X and Y or tell it to seralize just X and Y? i could just create my own xml in a string builder or something and if that's the only way, so be it. however i'm looking for a method that will employ the built in XML stuff. Thanks

  • Asp.net error object not set to a reference

    - by Frank
    Hi all, Because I rush in development (a lot of whip cracking here) and declare my objects at the top of the function and instantiate inside my try-catch block, I get a lot of the good old "object not set to an instance of an object" errors while doing TDD, and later if I do miss a branch that object was used in (doing VB now, would prefer C#) or just in every day coding, object not set to an instance of an object is a bit vague. Sure the stack trace sends me to the line the error occured at, but it would be nice if I could modify my logging to either name the object or its type because sometimes I have multiple objects on the same line. It's not the end of the world, but in the end it would save me a few minutes each day. Any ideas on how I can pass the info on which object wasn't set? Thanks

  • MustOverride Shared Methods in .Net

    - by Ben
    Hi I have a few class's that inherit from a base class. I want to enforce that all of these Class's implement a shared method foo(). I am not able to create the following on the base class Public MustOvveride Shared Sub foo() as this is not allowed. I also cant create an Interface that defines a Shared Sub Foo() and implement that in my derrived class's, as this also is not allowed. Does anyone know how i should implement this? p.s i realise my example is in VB and i have also tagged C#, the same problem applies to both languages and presumably the same fix would apply.

  • How to disable server-side caching on IIS 7.5 (asp net mvc3)

    - by troebr
    I'm struggling with my IIS setup regarding caching, here's a brief description of my problem: I'm making a site for mobile and non-mobile, sharing the same controllers. IE: mysite/page will serve either mysite/page.cshtml, or mysite/M/page.cshtml, depending on the device. Here's the catch, it worked fine with my local and integration environment (cassiini and iis 6), but on another machine (2008r2/iis 7.5), apparently there is an aggressive server-side caching policy: If I access the website from a desktop machine, I have the correct pages (desktop version) If now I use my mobile phone to access the site, I will have the desktop version, (which implies a server-side cache, my phone is not using the same network). On the contrary, if I were to restart the server and access the site using my phone first, then I will get the mobile version on my desktop (only for the pages I already visited of course). I tried 2 solutions so far: Disabling OutputCache from my Web.config: <httpModules> [..] <remove name="OutputCache" /> </httpModules> And unchecking "Enable output cache" in "Output Caching" for my site in IIS. What's bugging me is that I do not have this problem with my other server (iis 6.0), although caching is enabled on this one, which leads me to think it is related to iis 7 caching addition. My question is simple: how does one disable server-side caching on IIS 7.5? Thanks in advance for your iis lights!

  • Excel - referenced values via OleDB from .Net client

    - by ho
    I'm trying to read an Excel file (.xls, I think Excel 2003 compatible) via OleDB, but it fails to get the values for referenced fields. This is my current test code (please note, this is just part of the class): Private m_conn As OleDbConnection Public Sub New(ByVal fileName As String) Dim connString As String = String.Format("Provider=Microsoft.Jet.OLEDB.4.0;Data Source={0};Extended Properties=Excel 8.0;", fileName) m_conn = New OleDbConnection(connString) m_conn.Open() End Sub Public Sub GetSheet(ByVal sheet As String) Dim query As String = String.Format("SELECT * FROM [{0}]", sheet) Using cmd As OleDbCommand = m_conn.CreateCommand() cmd.CommandText = query Dim ds As New DataSet() Dim a As New OleDbDataAdapter(cmd) Using rdr As OleDbDataReader = cmd.ExecuteReader() While rdr.Read() Debug.WriteLine(rdr.Item(0).ToString()) End While End Using End Using End Sub But if the value is a reference (something like =+'MySheetName'!K37), I just get a DBNull from the call to rdr.Item(0). I can get around this by automating Excel instead, but would prefer not to have to use Excel automation so wondering if anyone knows how to do it.

  • iis7 integrated mode asp.net 4.0 forms authentication problem using IE8

    - by FiveTools
    Anyone experience any issues with IIS7, integrated mode forms authentication while using IE8? I have a website with a login form, once logged in, any postback causes the user to be logged out. This doesn't even happen consistently, sometimes I can login and not experience this issue, other times it happens instantly. I can not replicate the problem in any other browser and I cannot replicate on my development machine running / debugging vs2010.

  • ASP.NET MVC editor template for property

    - by Idsa
    Usually I render my forms by @Html.RenderModel, but this time I have a complex rendering logic and I render it manually. I decided to create a editor template for one property. Here is the code (copy pasted from default object editor template implementation): <%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl" %> <% var modelMetadata = ViewData.ModelMetadata; %> <% if (modelMetadata.HideSurroundingHtml) { %> <%= Html.Editor(modelMetadata.PropertyName) %> <% } else { %> <% if (!String.IsNullOrEmpty(Html.Label(modelMetadata.PropertyName).ToHtmlString())) { %> <div class="editor-label"><%= Html.Label(modelMetadata.PropertyName) %></div> <% } %> <div class="editor-field"> <%= Html.Editor(modelMetadata.PropertyName) %> <%= Html.ValidationMessage(modelMetadata.PropertyName) %> </div> <% } %> And here is how I use it: @Html.EditorFor(x => x.SomeProperty, "Property") //"Property" is template above But it didn't work: labels are rendered regardless of DisplayName and editors are not rendered at all (in Watches Html.Editor(modelMetadata.PropertyName shows empty string). What am I doing wrong?

  • How do you pass a generic delegate argument to a method in .NET 2.0 - UPDATED

    - by Seth Spearman
    Hello, I have a class with a delegate declaration as follows... Public Class MyClass Public Delegate Function Getter(Of TResult)() As TResult ''#the following code works. Public Shared Sub MyMethod(ByVal g As Getter(Of Boolean)) ''#do stuff End Sub End Class However, I do not want to explicitly type the Getter delegate in the Method call. Why can I not declare the parameter as follows... ... (ByVal g As Getter(Of TResult)) Is there a way to do it? My end goal was to be able to set a delegate for property setters and getters in the called class. But my reading indicates you can't do that. So I put setter and getter methods in that class and then I want the calling class to set the delegate argument and then invoke. Is there a best practice for doing this. I realize in the above example that I can set set the delegate variable from the calling class...but I am trying to create a singleton with tight encapsulation. For the record, I can't use any of the new delegate types declared in .net35. Answers in C# are welcome. Any thoughts? Seth

  • .Net 3.5 Windows Service hide WCF Service Host

    - by Melursus
    I got a Windows service installed on my development machine (that I made) and I want to interact with it. For a reason I don't know, each time I start the client, a WCF Service Host pop and said that the address is already in use ... which is true ... but how can I do to NOT start that Windows ? Is it because my two projects (server and client) are in the same solution ?

  • Create Access databases programatically through vb.net

    - by user87225
    Let me preface this by saying that I know this is a stupid way to go about this, but it needs to be handled in this way. I need to make an application that from a master database creates a number of access database files (tables of a larger db), then these are manually given to users who fill in data, the database files are emailed back to a user who, through the application, combines them again. The only part of this that I am unsure about is problematically creating the access db's. I have read that through Microsoft Jet OLE DB Provider and Microsoft ADO Ext I can create them (the tables and data), but I also need forms. I have yet to start writing anything and this is away from my area of work, so any insight/links would be much appreciated. Also, I would hope to be able to write this in the free express version of visual studio. Are there components needed that would prevent me from this? Thanks.

  • Asp.net razor textbox array for list items

    - by yycdev
    I can't find or figure out how to take a list of items (cupcakes) and display them in razor with a quantity field. What is happening is I am not able to get the values for each cupcake quantity in the list. Can you do textbox arrays in Razor? VIEW <div class="form-group"> <label>Cupcakes</label> @foreach (var cupcake in Model.CupcakeList) { @Html.TextBox("CupcakeQuantities", cupcake.Id) @cupcake.Name <br/> } </div> MODEL public List<Cupcake> CupcakeList { get; set; } public List<int> CupcakeQuantities { get; set; } CONTROLLER public ActionResult Create() { var model = new PartyBookingModel() { CupcakeList = db.Cupcakes.ToList(), CupcakeQuantities = new List<int>() }; return View(model); }

  • Strategy for developing a multi function asp.net web application

    - by user247023
    I'm about to start a new project and want some advice on how to implement. I need a web application which contains a booking module for reserving timeslots, and a time management module which will enable employees to clock in / clock out. If I am writing an update to the time managment module, I don't want to disrupt the booking engine availability by releasing a new solution containing both modules. to make things more difficult, there is some shared functionality like common users, roles and security. Here's a suggestion I've gotten, which sounds a bit cruddy, but may be functional. Write a 'container' web application which consists of basically a frame, and authentication / security features. This then has links which, will load the 2 independantly built and released web applications into the frame. I can see that say, if I wanted to update the time management module, I would only need to build and release this separately, and the rest of the solution would be 'untouched' Any better alternatives?

  • ASP.Net URL rewirting and redirecting....

    - by DDiVita
    I am trying to wrap my head around a URL rewrtie / redirect project I need to work on. We currently have this url: www.domain.com/Details/Detail.aspx?param1=8&param2=12345 Here is what the rewritten URL will look like: www.domain.com/Param1/8/Param2/12345 I am using the ISAPI_Rewrite filter to allow for the "nice" url and make the page think it is still using the old url. That works fine. Now, I need to redirect users, if they use the old URL, to the new URL. I fgiure I would need to use a combination of the filter and an HTTPModule / Handler to perfomr the redirect. Any ideas?

  • Global Import Aliasing in .NET

    - by Josh Stodola
    Using import aliasing in a single class, we can reference class library namespaces by assigning our own custom alias like this: Imports Db = Company.Lib.Data.Objects And then we are able to reference the classes inside of Company.Lib.Data.Objects by using the Db alias that we assigned. Is it possible to do this at the global level so that the alias is applied to the entire solution instead of the given file? Currently, we are working with web applications, so I was hoping we could add something to web.config, but I am also interested in whether or not this is possible with windows forms, console apps, and/or class libraries.

  • Clean way to output values in ASP.NET MVC Views when value is not null

    - by Swoop
    Is there a better way to write the code below? I have quite a few blocks that are similar, and this is making the code in the Viewpage very messy to work with. The data value with the associated label only needs to be output when certain conditions are met, which is almost always if the value is not null. The options I can think is to use a response.write to atleast minimize the usage of the ASP script tags, or to format the webpage is such a way that the label displays with an appropriate n/a type value. <% if (myData.Balance != null) { %> Balance: <%= String.Format("{0:C}", (myData.Balance))%> <% } %>

  • Simple ASP.NET MVC Routing question

    - by Robert
    Hi there, I have two pages in my simple MVC App with two defined routes: routes.MapRoute( "Results", // Route name "Results/{id}", // URL with parameters new { controller = "Results", action = "Index", id = "" } // Parameter defaults ); routes.MapRoute( "Default", // Route name "{controller}/{action}/{id}", // URL with parameters new { controller = "Main", action = "Index", id = UrlParameter.Optional } // Parameter defaults ); I needed to have the results page load with just a product ID such as this: [MyDomain....]/Results/12345. But also the main page does a POST (using JQuery) to the Results Controller for updates using this route: [MyDomain....]/Main/Update along with a data bag. This works fine when I only have the "Default" route. But when I added the other "Results" route, all the POST calls to update are failing. Any ideas what I'm doing wrong??? Thanks a lot.

  • Deploying a .Net App Source Control (SVN) over 32-bit AND 64-bit dev stations

    - by Mika Jacobi
    Here is the situation : Our Dev Team has heterogeneous OS systems, scattered between 32-bit and 64-bit. This is not ideal, we are actually planning to homogenize our infrastructure, but in the meantime we have to deal with it. The issue is that when a 32-bit developer checks out a 64-bit solution on SVN, he has to manually change the target platforms all over again to get it compiled (not to mention other side problems) My question is : What clean (though temporary) solution could be addressed in such situation, permitting each developer to keep his default project/platform settings while checking out and in from SVN. I guess that -at least for the first time a project/solution is checked out, a dev still has to tweak the setting manually to compile it properly. After that, according to relevant SVN filters, it is possible to ignore some settings files (which ones, by the way?) I am open to all clever and detailed suggestions. Thanks.
