  • POST from edit/create partial views loaded into Twitter Bootstrap modal

    - by mare
    I'm struggling with AJAX POST from the form that was loaded into Twitter Bootstrap modal dialog. Partial view form goes like this: @using (Html.BeginForm()) { // fields // ... // submit <input type="submit" value="@ButtonsRes.button_save" /> } Now this is being used in non AJAX editing with classic postbacks. Is it possible to use the same partial for AJAX functionality? Or should I abstract away the inputs into it's own partial view? Like this: @using (Ajax.BeginForm()) { @Html.Partial("~/Views/Shared/ImageEditInputs.cshtml") // but what to do with this one then? <input type="submit" value="@ButtonsRes.button_save" /> } I know how to load this into Bootstrap modal but few changes should be done on the fly: the buttons in Bootstrap modal should be placed in a special container (the modal footer), the AJAX POST should be done when clicking Save which would first, validate the form and keep the modal opened if not valid (display the errors of course) second, post and close the modal if everything went fine in the view that opened the modal, display some feedback information at the top that save was succesful. I'm mostly struggling where to put what JS code. So far I have this within the List view, which wires up the modals: $(document).ready(function () { $('.openModalDialog').click(function (event) { event.preventDefault(); var url = $(this).attr('href'); $.get(url, function (data) { $('#modalContent').html(data); $('#modal').modal('show'); }); }); }); The above code, however, doesn't take into the account the special Bootstrap modal content placeholder (header, content, footer). Is it possible to achieve what I want without having multiple partial views with the same inputs but different @using and without having to do hacks with moving the Submit button around?

  • UpdateModel() fails after migration from MVC 1.0 to MVC 2.0

    - by Alastair Pitts
    We are in the process of migrating our ASP.NET MVC 1.0 web app to MVC 2.0 but we have run into a small snag. In our report creation wizard, it is possible leave the Title text box empty and have it be populated with a generic title (in the post action). The code that does the update on the model of the Title is: if (TryUpdateModel(reportToEdit, new[] { "Title" })) { //all ok here try to create (custom validation and attach to graph to follow) //if title is empty get config subject if (reportToEdit.Title.Trim().Length <= 0) reportToEdit.Title = reportConfiguration.Subject; if (!_service.CreateReport(1, reportToEdit, SelectedUser.ID, reportConfigID, reportCategoryID, reportTypeID, deviceUnitID)) return RedirectToAction("Index"); } In MVC 1.0, this works correctly,the reportToEdit has an empty title if the textbox is empty, which is then populated with the Subject property. In MVC 2.0 this fails/returns false. If I add the line above: UpdateModel(reportToEdit, new[] { "Title" }); it throws System.InvalidOperationException was unhandled by user code Message="The model of type 'Footprint.Web.Models.Reports' could not be updated." Source="System.Web.Mvc" StackTrace: at System.Web.Mvc.Controller.UpdateModel[TModel](TModel model, String prefix, String[] includeProperties, String[] excludeProperties, IValueProvider valueProvider) at System.Web.Mvc.Controller.UpdateModel[TModel](TModel model, String[] includeProperties) at Footprint.Web.Controllers.ReportsController.Step1(FormCollection form) in C:\TFS Workspace\ExtBusiness_Footprint\Branches\apitts_uioverhaul\Footprint\Footprint.Web\Controllers\ReportsController.cs:line 398 at lambda_method(ExecutionScope , ControllerBase , Object[] ) at System.Web.Mvc.ActionMethodDispatcher.Execute(ControllerBase controller, Object[] parameters) at System.Web.Mvc.ReflectedActionDescriptor.Execute(ControllerContext controllerContext, IDictionary`2 parameters) at System.Web.Mvc.ControllerActionInvoker.InvokeActionMethod(ControllerContext controllerContext, ActionDescriptor actionDescriptor, IDictionary`2 parameters) at System.Web.Mvc.ControllerActionInvoker.<>c__DisplayClassd.<InvokeActionMethodWithFilters>b__a() at System.Web.Mvc.ControllerActionInvoker.InvokeActionMethodFilter(IActionFilter filter, ActionExecutingContext preContext, Func`1 continuation) InnerException: Reading the MVC2 Release notes I see this breaking change: Every property for model objects that use IDataErrorInfo to perform validation is validated, regardless of whether a new value was set. In ASP.NET MVC 1.0, only properties that had new values set would be validated. In ASP.NET MVC 2, the Error property of IDataErrorInfo is called only if all the property validators were successful. but I'm confused how this is affecting me. I'm using the entity framework generated classes. Can anyone pinpoint why this is failing?

  • .NET Framework 4 Client Profile vs .NET Framework 3.5 Client Profile

    - by Janusz
    Currently I am targeting .NET Framework 3.5 Client profile. Under certain conditions (when .NET 1.x or 2.x is installed) the client profile is not installed and instead full version of .NET Framework 3.5. is installed. This limitation has been removed from .NET 4.0 profile - therefore its a nice improvement that significantly reduces download size on certain PCs. However, if I target application to .NET 4.0 then all the clients will have to download new framework. I think ideal scenario would be to target .NET 3.5 profile but point installer to .NET 4.0 client profile. This way PCs with 3.5 installed (65% from our tests at the moment) would be fine and the rest would install .NET 4.0. Is my thinking correct or its not feasible? Will .NET 3.5 profile application run with only .NET 4.0 profile installed? Thank you

  • Problem showing modelstate errors while using RenderPartialToString

    - by Martin
    Im using the following code: public string RenderPartialToString(ControllerContext context, string partialViewName, ViewDataDictionary viewData, TempDataDictionary tempData) { ViewEngineResult result = ViewEngines.Engines.FindPartialView(context, partialViewName); if (result.View != null) { StringBuilder sb = new StringBuilder(); using (StringWriter sw = new StringWriter(sb)) { using (HtmlTextWriter output = new HtmlTextWriter(sw)) { ViewContext viewContext = new ViewContext(context, result.View, viewData, tempData, output); result.View.Render(viewContext, output); } } return sb.ToString(); } return String.Empty; } To return a partial view and a form through JSON. It works as it should, but as soon as I get modelstate errors my ValidationSummary does not show. The JSON only return the default form but it does not highlight the validation errors or show the validation summary. Am I missing something? This is how I call the RenderPartialToString: string partialView = RenderPartialToString(this.ControllerContext, "~/Areas/User/Views/Account/ChangeAccountDetails.ascx", new ViewDataDictionary(avd), new TempDataDictionary());

  • ASP.NET - FileUpload with PostBack Trigger

    - by Echilon
    I have an UpdatePanel which has an upload control and a button to upload. The button is set as a trigger, but the event handler for the button fails to execute on the first PostBack. My ASPX code is: <asp:UpdatePanel ID="updPages" runat="server" UpdateMode="Conditional"> <ContentTemplate> <div class="tabs"> <ul> <li><asp:LinkButton ID="lnkContentsPages" runat="server" OnClick="updateContents" CommandArgument="pages">Pages</asp:LinkButton></li> <%-- these tabs change the ActiveViewIndex to show a different UserControl --%> <li><asp:LinkButton ID="lnkContentsImages" runat="server" OnClick="updateContents" CommandArgument="images">Images</asp:LinkButton></li> </ul> <div class="tabbedContent"> <asp:MultiView runat="server" ID="mltContentsInner" ActiveViewIndex="0"> <asp:View ID="viwContentsImages" runat="server"> // ajax usercontrol for a list of images - works fine with ajax <fieldset> <legend>Upload New</legend> <div class="formRow"> <asp:Label ID="lblFile" runat="server" Text="Filename" AssociatedControlID="uplFile" /> <asp:FileUpload ID="uplFile" runat="server" /> </div> <div class="formRow"> <asp:Label ID="lblImageDescription" runat="server" Text="Description" AssociatedControlID="txtImageDescription" /> <asp:TextBox runat="server" ID="txtImageDescription" /> </div> <asp:Button ID="btnUpload" runat="server" Text="Upload" CssClass="c3button btnUpload" CausesValidation="false" OnClick="btnUpload_Click" /> </fieldset> </asp:View> <asp:View ID="viwContentsPages" runat="server"> // ajax usercontrol - works fine with ajax </asp:View> </asp:MultiView> </div> </div> </ContentTemplate> <Triggers> <asp:PostBackTrigger ControlID="btnUpload" /> </Triggers> </asp:UpdatePanel> The button works without fail on the second and subsequent times, just not the first. Is there any reason for this?

  • Can I disable DataAnnotations validation on DefaultModelBinder?

    - by Max Toro
    I want DefaultModelBinder not to perform any validation based on DataAnnotations metadata. I'm already using DataAnnotations with DynamicData for the admin area of my site, and I need a different set of validation rules for the MVC based front-end. I'm decorating my classes with the MetadataType attribute. If I could have different MetadataType classes for the same model but used on different scenarios that would be great. If not I'm fine with just disabling the validation on the DefaultModelBinder, either by setting some property or by creating a specialized version of it.

    I have a shared master page which I am using from 2 different areas in my mvc 2 app. The master page has an action link which currently specifies the controller and action, but of course the link doesn't work if I'm in the wrong area. I see no overload for actionlink that takes an area parameter, is it possible to do?

  • Best practices concerning view model and model updates with a subset of the fields

    - by Martin
    By picking MVC for developing our new site, I find myself in the midst of "best practices" being developed around me in apparent real time. Two weeks ago, NerdDinner was my guide but with the development of MVC 2, even it seems outdated. It's an thrilling experience and I feel privileged to be in close contact with intelligent programmers daily. Right now I've stumbled upon an issue I can't seem to get a straight answer on - from all the blogs anyway - and I'd like to get some insight from the community. It's about Editing (read: Edit action). The bulk of material out there, tutorials and blogs, deal with creating and view the model. So while this question may not spell out a question, I hope to get some discussion going, contributing to my decision about the path of development I'm to take. My model represents a user with several fields like name, address and email. All the names, in fact, on field each for first name, last name and middle name. The Details view displays all these fields but you can change only one set of fields at a time, for instance, your names. The user expands a form while the other fields are still visible above and below. So the form that is posted back contains a subset of the fields representing the model. While this is appealing to us and our layout concerns, for various reasons, it is to be shunned by serious MVC-developers. I've been reading about some patterns and best practices and it seems that this is not in key with the paradigm of viewmodel == view. Or have I got it wrong? Anyway, NerdDinner dictates using FormCollection och UpdateModel. All the null fields are happily ignored. Since then, the MVC-community has abandoned this approach to such a degree that a bug in MVC 2 was not discovered. UpdateModel does not work without a complete model in your formcollection. The view model pattern receiving most praise seems to be Dedicated view model that contains a custom view model entity and is the only one that my design issue could be made compatible with. It entails a tedious amount of mapping, albeit lightened by the use of AutoMapper and the ideas of Jimmy Bogard, that may or may not be worthwhile. He also proposes a 1:1 relationship between view and view model. In keeping with these design paradigms, I am to create a view and associated view for each of my expanding sets of fields. The view models would each be nearly identical, differing only in the fields which are read-only, the views also containing much repeated markup. This seems absurd to me. In future I may want to be able to display two, more or all sets of fields open simultaneously. I will most attentively read the discussion I hope to spark. Many thanks in advance.

    Is anyone doing dyanamic client validation and if so how are you doing it.

  • Different controllers with the same name in two different areas results in a routing conflict

    - by HackedByChinese
    I have two areas: ControlPanel and Patients. Both have a controller called ProblemsController that are similar in name only. The desired results would be routes that yield /controlpanel/problems = MyApp.Areas.ControlPanel.Controllers.ProblemsController and /patients/problems = MyApp.Areas.Patients.Controllers.ProblemsController. Each has routes configured like this: public override void RegisterArea(AreaRegistrationContext context) { context.MapRoute( "**Area Name Here**_default", "**Area Name Here**/{controller}/{action}/{id}", new { action = "Index", id = UrlParameter.Optional } ); } where **Area Name Here** is either ControlPanel or Patients. When I go to /patients/problems/create (for example), I get a 404 where the routing error says: A public action method 'create' was not found on controller 'MyApp.Areas.ControlPanel.Controllers.ProblemsController'. I'm not sure what I'm doing wrong.

  • Windows Service HTTPListener Memory Issue

    - by crawshaws
    Hi all, Im a complete novice to the "best practices" etc of writing in any code. I tend to just write it an if it works, why fix it. Well, this way of working is landing me in some hot water. I am writing a simple windows service to server a single webpage. (This service will be incorperated in to another project which monitors the services and some folders on a group of servers.) My problem is that whenever a request is recieved, the memory usage jumps up by a few K per request and keeps qoing up on every request. Now ive found that by putting GC.Collect in the mix it stops at a certain number but im sure its not meant to be used this way. I was wondering if i am missing something or not doing something i should to free up memory. Here is the code: Public Class SimpleWebService : Inherits ServiceBase 'Set the values for the different event log types. Public Const EVENT_ERROR As Integer = 1 Public Const EVENT_WARNING As Integer = 2 Public Const EVENT_INFORMATION As Integer = 4 Public listenerThread As Thread Dim HTTPListner As HttpListener Dim blnKeepAlive As Boolean = True Shared Sub Main() Dim ServicesToRun As ServiceBase() ServicesToRun = New ServiceBase() {New SimpleWebService()} ServiceBase.Run(ServicesToRun) End Sub Protected Overrides Sub OnStart(ByVal args As String()) If Not HttpListener.IsSupported Then CreateEventLogEntry("Windows XP SP2, Server 2003, or higher is required to " & "use the HttpListener class.") Me.Stop() End If Try listenerThread = New Thread(AddressOf ListenForConnections) listenerThread.Start() Catch ex As Exception CreateEventLogEntry(ex.Message) End Try End Sub Protected Overrides Sub OnStop() blnKeepAlive = False End Sub Private Sub CreateEventLogEntry(ByRef strEventContent As String) Dim sSource As String Dim sLog As String sSource = "Service1" sLog = "Application" If Not EventLog.SourceExists(sSource) Then EventLog.CreateEventSource(sSource, sLog) End If Dim ELog As New EventLog(sLog, ".", sSource) ELog.WriteEntry(strEventContent) End Sub Public Sub ListenForConnections() HTTPListner = New HttpListener HTTPListner.Prefixes.Add("http://*:1986/") HTTPListner.Start() Do While blnKeepAlive Dim ctx As HttpListenerContext = HTTPListner.GetContext() Dim HandlerThread As Thread = New Thread(AddressOf ProcessRequest) HandlerThread.Start(ctx) HandlerThread = Nothing Loop HTTPListner.Stop() End Sub Private Sub ProcessRequest(ByVal ctx As HttpListenerContext) Dim sb As StringBuilder = New StringBuilder sb.Append("<html><body><h1>Test My Service</h1>") sb.Append("</body></html>") Dim buffer() As Byte = Encoding.UTF8.GetBytes(sb.ToString) ctx.Response.ContentLength64 = buffer.Length ctx.Response.OutputStream.Write(buffer, 0, buffer.Length) ctx.Response.OutputStream.Close() ctx.Response.Close() sb = Nothing buffer = Nothing ctx = Nothing 'This line seems to keep the mem leak down 'System.GC.Collect() End Sub End Class Please feel free to critisise and tear the code apart but please BE KIND. I have admitted I dont tend to follow the best practice when it comes to coding.

  • Using jQuery to load Telerik MVC scripts.

    - by ProfK
    I'm busy building my first MVC app that uses the Telerik MVC components. Their docs specify that the ScriptRegistrar helper be called right at the bottom of a view, e.g. "at the end of the master page.". I assume this renders a script block that must only run when the page has loaded. I normally prefer to achieve this using jQuery, and keep all my script related stuff at the top of my master page, preferably in the <head> tag. Is there anything I can do to achieve this with the Telerik components and do away with the lone and forgotten helper call at the bottom of my master page?

  • Built in method to encode ampersands in urls returned from Url.Action?

    - by Blegger
    I am using Url.Action to generate a URL with two query parameters on a site that has a doctype of XHTML strict. Url.Action("ActionName", "ControllerName", new { paramA="1" paramB="2" }) generates: /ControllerName/ActionName/?paramA=1&paramB=2 but I need it to generate the url with the ampersand escaped: /ControllerName/ActionName/?paramA=1&amp;paramB=2 The fact that Url.Action is returning the URL with the ampersand not escaped breaks my HTML validation. My current solution is to just manually replace ampersand in the URL returned from Url.Action with an escaped ampersand. Is there a built in or better solution to this problem?

  • Extending the RoleProvider GetRolesForUser()

    - by Farinha
    The GetRolesForUser() method in the RoleProvider takes the user login name and returns the list of roles for that user. But in my application this is not enough, I need a few more pieces of information to be able to get the user's roles. How can I get this extra information into the method? I have it in the Session, but I found out that Session is not available in the RoleProvider. What I had in mind was putting this extra info in some class that extends MembershipUser, assuming I can get to it inside the RoleProvider. But I don't know how to create the CustomMembershipUser and make it part of the MembershipProvider. Is this even possible? The easy way out would be using cookies, but I'm trying to keep away from it.

  • VS 2010 MVC Formatting

    Hello, MVC is formatting my code horribly, and I was wondering if you can turn it off? I feel the answer is no, but I was hoping VS 2010 had built in a setting... Here's what its formatting as: <% if (org.UserKey.HasValue) { %> <%= org.Reference(i => i.UserReference).Email%> <% } else { %> <%= org.UserEmail%> <% } %> I want the beginning brackets on the same line as the if and the else...

  • jqgrid retrieving empty rows using webapi (REST)

    - by polonskyg
    I'm using jqgrid in an ASPNET MVC4 project with WebApi (REST), Entity Framework 5 using Unit Of Work and Repository patterns. My problem is that I see the data flowing as json to the browser and I see three rows in the grid, but those rows are empty, and the data is not shown (three empty rows in the grid). This is method to get the data in the WebApi controller: public dynamic GetGridData(int rows, int page, string sidx, string sord) { var pageSize = rows; var index = sidx; var order = sord; var categories = Uow.Categories.GetAll().OrderBy(t => (string.IsNullOrEmpty(index) ? "Id" : index) + " " + (order ?? "desc")); var pageIndex = Convert.ToInt32(page) - 1; var totalRecords = categories.Count(); var totalPages = (int)Math.Ceiling((float) totalRecords / (float) pageSize); var categoriesPage = categories.Skip(pageIndex * pageSize).Take(pageSize).ToList(); return new { total = totalPages, page = page, records = totalRecords, rows = (from category in categoriesPage select new { id = category.Id.ToString(), cell = new string[] { category.Id.ToString(), category.Name, category.Description } }).ToArray() }; } This is the json received in the browser { "total": 1, "page": 1, "records": 3, "rows": [{ "id": "1", "cell": ["1", "Category 1", null] }, { "id": "3", "cell": ["3", "Category 3", "asAS"] }, { "id": "4", "cell": ["4", "Category 4", null] }] } This is the .js file with jqgrid jQuery("#ajaxGrid").jqGrid({ url: $("#ServiceUrl").val(), datatype: "json", jsonReader: { repeatitems: false, id: "Id" }, colNames: ['Id', 'Name', 'Description'], colModel: [ { name: 'id', editable: true, sortable: true, hidden: true, align: 'left' }, { name: 'name', editable: true, sortable: true, hidden: false, align: 'left' }, { name: 'description', editable: true, sortable: true, hidden: false, align: 'left' } ], mtype: 'GET', rowNum: 15, pager: '#ajaxGridPager', rowList: [10, 20, 50, 100], caption: 'List of Categories', imgpath: $("#ServiceImagesUrl").val(), altRows: true, shrinkToFit: true, viewrecords: true, autowidth: true, height: 'auto', error: function(x, e) { alert(x.readyState + " "+ x.status +" "+ e.msg); } }); function updateDialog(action) { return { url: $("#ServiceUrl").val(), closeAfterAdd: true, closeAfterEdit: true, afterShowForm: function (formId) { }, modal: true, onclickSubmit: function (params) { var list = $("#ajaxGrid"); var selectedRow = list.getGridParam("selrow"); params.url += "/" + list.getRowData(selectedRow).Id; params.mtype = action; }, width: "300", ajaxEditOptions: { contentType: "application/json" }, serializeEditData: function (data) { delete data.oper; return JSON.stringify(data); } }; } jQuery("#ajaxGrid").jqGrid( 'navGrid', '#ajaxGridPager', { add: true, edit: true, del: true, search: false, refresh: false }, updateDialog('PUT'), updateDialog('POST'), updateDialog('DELETE') ); BTW, If I want to return jqGridData instead the dynamic, How should I do it? Did is showing empty rows as well: public class jqGridData<T> where T : class { public int page { get; set; } public int records { get; set; } public IEnumerable<T> rows { get; set; } public decimal total { get; set; } } public jqGridData<Category> GetGridData(int rows, int page, string sidx, string sord) { var pageSize = rows; var index = sidx; var order = sord; var categories = Uow.Categories.GetAll().OrderBy(t => (string.IsNullOrEmpty(index) ?

  • What is the web.debug.config and web.release.config file for?

    - by chobo
    Hi, I just upgraded to VS 2010 and MVC 2.0 and I noticed the web.config has two additional files attached to it? Are thee files used to specify debug and release specific settings, so you don't clutter up the main web.config? Does it even make sense to place a connection string in the root web.config file if I have have a local and remote one in the debug and release web.configs respectively. Thanks!

  • Message pump in .NET Windows service

    - by Pickles
    I have a Windows Service written in C# that handles all of our external hardware I/O for a kiosk application. One of our new devices is a USB device that comes with an API in a native DLL. I have a proper P/Invoke wrapper class created. However, this API must be initialized with an HWnd to a windows application because it uses the message pump to raise asynchronous events. Besides putting in a request to the hardware manufacturer to provide us with an API that does not depend on a Windows message pump, is there any way to manually instantiate a message pump in a new thread in my Windows Service that I can pass into this API? Do I actually have to create a full Application class, or is there a lower level .NET class that encapsulates a message pump?

  • UrlHelper and ViewContext inside an Authorization Attribute

    - by DM
    I have a scenario that I haven't been able to solve: I'm toying around with creating my own custom authorization attribute for mvc. The main bit of functionality I would like to add is to have the ability to change where the user gets redirected if they are not in a certain role. I don't mind that the system sends them back to the login page if they're not authenticated, but I would like to choose where to send them if they are authenticated but not allowed to access that action method. Here's is what I would like to do: public class CustomAuthorizeAttribute : AuthorizeAttribute { public string Action; public string Controller; protected override bool AuthorizeCore(System.Web.HttpContextBase httpContext) { // if User is authenticated but not in the correct role string url = Url.Action(this.Action, this.Controller); httpContext.Response.Redirect(url); } } And as an added bonus I would like to have access to ViewContext and TempData before I do the redirect. Any thoughts on how I could get instantiate a UrlHelper and ViewContext in the attribute?
