  • ASP.NET MVC and AjaxFileUpload

    - by Jimbojones
    Ok, this is driving me nuts. I have been trying to figure this out forever now. I want to to perform an async upload using ajaxFileUpload. I have it posting the file to my controller just fine, however, when i try to return a JsonResult from it, I get a "Save File As" dialog box. I have tried everything to get around this and i either get an error or the "Save As" dialog. Im assuming that it has something to do with the content type that is being passed in when the file gets posted. I would be greatly appreciative if anyone could help. Thanks in advance!

  • Error using ASP.NET 3.5 Chart control within a Repeater control

    - by tuseau
    Hi, I'm getting the error "Microsoft JScript runtime error: Sys.WebForms.PageRequestManagerServerErrorException: Error executing child request for ChartImg.axd" at runtime from my Chart control. I have read one solution to this error message as documented here: http://social.msdn.microsoft.com/Forums/en-US/MSWinWebChart/thread/1dc4b352-c9a5-49dc-8f35-9b176509faa1/ but this does not solve my problem. I have the Chart within a Repeater control, which is within an ajax UpdatePanel. When I take the chart out of the Repeater (but leave it in the UpdatePanel), it works. So I'm thinking it is to do with the Repeater. Anyone got any ideas? Thanks in advance.

  • DDD principlers and ASP.NET MVC project design

    - by kaivalya
    Two part questions I have a product aggregate that has; Prices PackagingOptions ProductDescriptions ProductImages etc I have modeled one product repository and did not create individual repositories for any of the child classes. All db operations are handled through product repository. Am I understanding the DDD concept correctly so far? Sometimes the question comes to my mind that having a repository for lets say packaging options could make my life easier by directly fetching a the packaging option from the DB by using its ID instead of asking the product repository to find it in its PackagingOptions collection and give it to me.. Second part is managing the edit create operations using ASP.MVC frame work I am currently trying to manage all add edit remove of these child collections of product through product controller(sound right?). One challenge I am now facing is; If I edit a specific packaging option of product through mydomain/product/editpackagingoption/10 I have access to the id of the packaging option But I don't have the ID of the product it self and this forces me to write a query to first find the product that has this specific packaging option then edit that product and the revelant packaging option. I can do this as all packaging option have their unique ID but this would fail if I have collections that don't have unique ID. That feels very wrong.. The next option I thought of is sending both the product and packaging option IDs on the url like; mydomain/product/editpackagingoption/3/10 But I am not sure if that is a good design either. So I am at a point that I am a bit confused. might be having fundamental misunderstandings around all of this... I would appreciate if you bear with the long question and help me put this together. thanks!

  • What is good practice in .NET system architecture design concerning multiple models and aggregates

    - by BuzzBubba
    I'm designing a larger enterprise architecture and I'm in a doubt about how to separate the models and design those. There are several points I'd like suggestions for: - models to define - way to define models Currently my idea is to define: Core (domain) model Repositories to get data to that domain model from a database or other store Business logic model that would contain business logic, validation logic and more specific versions of forms of data retrieval methods View models prepared for specifically formated data output that would be parsed by views of different kind (web, silverlight, etc). For the first model I'm puzzled at what to use and how to define the mode. Should this model entities contain collections and in what form? IList, IEnumerable or IQueryable collections? - I'm thinking of immutable collections which IEnumerable is, but I'd like to avoid huge data collections and to offer my Business logic layer access with LINQ expressions so that query trees get executed at Data level and retrieve only really required data for situations like the one when I'm retrieving a very specific subset of elements amongst thousands or hundreds of thousands. What if I have an item with several thousands of bids? I can't just make an IEnumerable collection of those on the model and then retrieve an item list in some Repository method or even Business model method. Should it be IQueryable so that I actually pass my queries to Repository all the way from the Business logic model layer? Should I just avoid collections in my domain model? Should I void only some collections? Should I separate Domain model and BusinessLogic model or integrate those? Data would be dealt trough repositories which would use Domain model classes. Should repositories be used directly using only classes from domain model like data containers? This is an example of what I had in mind: So, my Domain objects would look like (e.g.) public class Item { public string ItemName { get; set; } public int Price { get; set; } public bool Available { get; set; } private IList<Bid> _bids; public IQueryable<Bid> Bids { get { return _bids.AsQueryable(); } private set { _bids = value; } } public AddNewBid(Bid newBid) { _bids.Add(new Bid {.... } } Where Bid would be defined as a normal class. Repositories would be defined as data retrieval factories and used to get data into another (Business logic) model which would again be used to get data to ViewModels which would then be rendered by different consumers. I would define IQueryable interfaces for all aggregating collections to get flexibility and minimize data retrieved from real data store. Or should I make Domain Model "anemic" with pure data store entities and all collections define for business logic model? One of the most important questions is, where to have IQueryable typed collections? - All the way from Repositories to Business model or not at all and expose only solid IList and IEnumerable from Repositories and deal with more specific queries inside Business model, but have more finer grained methods for data retrieval within Repositories. So, what do you think? Have any suggestions?

  • ASP.Net - DataRepeater with multiple templates and multiple datasources in one

    - by NicoJuicy
    This is my problem. I'm using different sql-queries for fetching some people, some come from my database and some come from an external database. They are all sorted in the same "list", only the difference is, that the people who come from our database will have a different lay-out and there will be less of them in a row (eg. 1 in a row), the list of people who come from the external database will be ordered by 3 (in a row). How can i implement this using a repeater? And how would the pagination work? Any "logical", working alternatives will be appreciated also, but i prefer to keep my current workflow to solve this problem. Short: - Multiple datasources - Multiple templates for the different datasources (1 in a row, 3 in a row) - Pagination in this problem?

  • GnuPG + Webservice + ASP.NET

    - by Karol Bladek
    Hi! I'm exhausted. I have installed GnuPG and exported secret key, and two public keys (my own and one of my client) from another instance of GnuPG. I try to configure 'my encrypting/decrypting' method on the local machine. When I run encrypting method from a little console application it works good. When I run this (same! - with the same body) method from my webservice on my local machine ... I have an ExitCode = 2. Happy in fact of catching the error message, but unhappy with their body. "gpg: no default secret key: secret key not available gpg: XXXXXXXXXXXXXXXX.xml: sign+encrypt failed: secret key not available" What should I do? Whats wrong? Best regards, Karol Bladek

  • Asp.net MVC 2, MvcContrib, and a base controller with redirect actions

    - by jeriley
    I've got a base controller that takes a couple generics, nothing overly fancy. public class SystemBaseController<TForm, TFormViewModel> : Controller where TForm : class, IForm where TFormViewModel : class, IViewModel ok, no big deal. I have a method "CompleteForm" that takes in the viewModel, looks kinda like this ... public ActionResult CompleteForm(TFormViewModel viewModel) { //does some stuff return this.RedirectToAction(c => c.FormInfo(viewModel)); } Problem is, the controller that inherits this, like so public class SalesFormController : SystemBaseController<SalesForm, SalesViewModel> { } I end up getting a error from MvcContrib - Controller name must end in 'Controller' at this point ... public RedirectToRouteResult(Expression<Action<T>> expression) : this(expression, expr => Microsoft.Web.Mvc.Internal.ExpressionHelper.GetRouteValuesFromExpression(expr)) {} The expression that's passed in is correct (SystemBaseController blahblah) but I'm not sure why its 1.) saying there's no controller at the end, and 2.) if I pull out everything into the controller (out of the base), works just fine. Do I need to write or setup some kind of action filter of my own or what am I missing?

  • ASP.NET MVC - Localization route

    - by ropstah
    Hi, i'd like to create localized URL's for my site. They should obviously point to the same controller actions, but I want the first routevalues to -always- be the location/language specification. Is this possible? http://www.website.com/en/us/controller/action http://www.website.com/en/gb/controller/action I understand it can be done by defining {language} and {location} in every route, but i'm looking for a slick, non-hacky solution.

  • Asp.net Webdeployment Project override applicationSettings

    - by citronas
    I got a web deyploment project for a web application project in vs 2008. While building the web deployment project, I want to replace properties in the web.config. My settings are autogenrated by the deisgner. <applicationSettings> <NAMESPACE.Properties.Settings> <setting name="Testenvironment" serializeAs="String"> <value>True</value> </setting> </NAMESPACE.Properties.Settings> </applicationSettings> In the config file which contains the settings for the specific server looks like the following: <?xml version="1.0"?> <applicationSettings> <NAMESPACE.Properties.Settings> <setting name="Testenvironment" serializeAs="String"> <value>False</value> </setting> </NAMESPACE.Properties.Settings> </applicationSettings> Sadly, this does not work. I get an error "The format of a configSource file must be an element containing the name of the section" that highlights the second line (2nd example code). How must the Tag be named in order to make evertything work? Edit: Deleting the "applicationSetting"-Tags does not work either.

  • ASP .NET - Substitution and page output (donut) caching - How to pass custom argument to HttpRespons

    - by zzare
    I would like to use substitution feature of donut caching. public static string GetTime(HttpContext context) { return DateTime.Now.ToString("T"); } ... The cached time is: <%= DateTime.Now.ToString("T") %> <hr /> The substitution time is: <% Response.WriteSubstitution(GetTime); %> ...But I would like to pass additional parameter to callback function beside HttpContext. so the question is: How to pass additional argument to GetTime callback? for instance, something like this: public static string GetTime(HttpContext context, int newArgument) { // i'd like to get sth from DB by newArgument // return data depending on the db values // ... this example is too simple for my usage if (newArgument == 1) return ""; else return DateTime.Now.ToString("T"); }

  • Many to Many with LINQ-To-Sql and ASP.NET MVC

    - by Jonathan Stowell
    Hi All, I will restrict this to the three tables I am trying to work with Problem, Communications, and ProbComms. The scenario is that a Student may have many Problems concurrently which may affect their studies. Lecturers may have future communications with a student after an initial problem is logged, however as a Student may have multiple Problems the Lecturer may decide that the discussion they had is related to more than one Problem. Here is a screenshot of the LINQ-To-Sql representation of my DB: LINQ-To-Sql Screenshot At the moment in my StudentController I have a StudentFormViewModel Class: // //ViewModel Class public class StudentFormViewModel { IProbCommRepository probCommRepository; // Properties public Student Student { get; private set; } public IEnumerable<ProbComm> ProbComm { get; private set; } // // Dependency Injection enabled constructors public StudentFormViewModel(Student student, IEnumerable<ProbComm> probComm) : this(new ProbCommRepository()) { this.Student = student; this.ProbComm = probComm; } public StudentFormViewModel(IProbCommRepository pRepository) { probCommRepository = pRepository; } } When I go to the Students Detail Page this runs: public ActionResult Details(string id) { StudentFormViewModel viewdata = new StudentFormViewModel(studentRepository.GetStudent(id), probCommRepository.FindAllProblemComms(id)); if (viewdata == null) return View("NotFound"); else return View(viewdata); } The GetStudent works fine and returns an instance of the student to output on the page, below the student I output all problems logged against them, but underneath these problems I want to show the communications related to the Problem. The LINQ I am using for ProbComms is This is located in the Model class ProbCommRepository, and accessed via a IProbCommRepository interface: public IQueryable<ProbComm> FindAllProblemComms(string studentEmail) { return (from p in db.ProbComms where p.Problem.StudentEmail.Equals(studentEmail) orderby p.Problem.ProblemDateTime select p); } However for example if I have this data in the ProbComms table: ProblemID CommunicationID 1 1 1 2 The query returns two rows so I assume I somehow have to groupby Problem or ProblemID but I am not too sure how to do this with the way I have built things as the return type has to be ProbComm for the query as thats what Model class its located in. When it comes to the view the Details.aspx calls two partial views each passing the relevant view data through, StudentDetails works fine page: <%@ Page Title="" Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage<MitigatingCircumstances.Controllers.StudentFormViewModel>" %> <% Html.RenderPartial("StudentDetails", this.ViewData.Model.Student); %> <% Html.RenderPartial("StudentProblems", this.ViewData.Model.ProbComm); %> StudentProblems uses a foreach loop to loop through records in the Model and I am trying another foreach loop to output the communication details: <%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl<IEnumerable<MitigatingCircumstances.Models.ProbComm>>" %> <script type="text/javascript" language="javascript"> $(document).ready(function() { $("DIV.ContainerPanel > DIV.collapsePanelHeader > DIV.ArrowExpand").toggle( function() { $(this).parent().next("div.Content").show("slow"); $(this).attr("class", "ArrowClose"); }, function() { $(this).parent().next("div.Content").hide("slow"); $(this).attr("class", "ArrowExpand"); }); }); </script> <div class="studentProblems"> <% var i = 0; foreach (var item in Model) { %> <div id="ContainerPanel<%= i = i + 1 %>" class="ContainerPanel"> <div id="header<%= i = i + 1 %>" class="collapsePanelHeader"> <div id="dvHeaderText<%= i = i + 1 %>" class="HeaderContent"><%= Html.Encode(String.Format("{0:dd/MM/yyyy}", item.Problem.ProblemDateTime))%></div> <div id="dvArrow<%= i = i + 1 %>" class="ArrowExpand"></div> </div> <div id="dvContent<%= i = i + 1 %>" class="Content" style="display: none"> <p> Type: <%= Html.Encode(item.Problem.CommunicationType.TypeName) %> </p> <p> Problem Outline: <%= Html.Encode(item.Problem.ProblemOutline)%> </p> <p> Mitigating Circumstance Form: <%= Html.Encode(item.Problem.MCF)%> </p> <p> Mitigating Circumstance Level: <%= Html.Encode(item.Problem.MitigatingCircumstanceLevel.MCLevel)%> </p> <p> Absent From: <%= Html.Encode(String.Format("{0:g}", item.Problem.AbsentFrom))%> </p> <p> Absent Until: <%= Html.Encode(String.Format("{0:g}", item.Problem.AbsentUntil))%> </p> <p> Requested Follow Up: <%= Html.Encode(String.Format("{0:g}", item.Problem.RequestedFollowUp))%> </p> <p>Problem Communications</p> <% foreach (var comm in Model) { %> <p> <% if (item.Problem.ProblemID == comm.ProblemID) { %> <%= Html.Encode(comm.ProblemCommunication.CommunicationOutline)%> <% } %> </p> <% } %> </div> </div> <br /> <% } %> </div> The issue is that using the example data before the Model has two records for the same problem as there are two communications for that problem, therefore duplicating the output. Any help with this would be gratefully appreciated. Thanks, Jon

  • creating new usercntrols at runtime in ASP.NET MVC

    - by Paul Connolly
    Hi everyone, My situation is that the user is creating an entity on my site which contains the particlars of the driectors of that company, name address etc.. The Director form is a separate user control with the appropriate textboxes etc. At run time we don't know how many of these directors there will be so I need one to be able to use something like an "ADD DIRECTOR" or "DELETE DIRECTOR" button which will present or delete the another usercontrol to add the additional director. Currently I am trying to make this happen within a pane of the JQuery Accordion control. I have looked many places for how to do this but to no avail. Can anyone tell me where I might find some inforamation about how I can do this? All the best Paul

  • Problem with custom paging in ASP.NET

    - by JohnCC
    I'm trying to add custom paging to my site using the ObjectDataSource paging. I believe I've correctly added the stored procedures I need, and brought them up through the DAL and BLL. The problem I have is that when I try to use it on a page, I get an empty datagrid. <%@ Page Language="C#" AutoEventWireup="true" CodeFile="PageTest.aspx.cs" Inherits="developer_PageTest" %> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head runat="server"> <title></title> </head> <body> <form id="form1" runat="server"> <div> <asp:ObjectDataSource ID="ObjectDataSource1" SelectMethod="GetMessagesPaged" EnablePaging="true" SelectCountMethod="GetMessagesCount" TypeName="MessageTable" runat="server" > <SelectParameters> <asp:Parameter Name="DeviceID" Type="Int32" DefaultValue="112" /> <asp:Parameter Name="StartDate" Type="DateTime" DefaultValue="" ConvertEmptyStringToNull="true"/> <asp:Parameter Name="EndDate" Type="DateTime" DefaultValue="" ConvertEmptyStringToNull="true"/> <asp:Parameter Name="BasicMatch" Type="Boolean" ConvertEmptyStringToNull="true" DefaultValue="" /> <asp:Parameter Name="ContainsPosition" Type="Boolean" ConvertEmptyStringToNull="true" DefaultValue="" /> <asp:Parameter Name="Decoded" Type="Boolean" ConvertEmptyStringToNull="true" DefaultValue="" /> <%-- <asp:Parameter Name="StartRowIndex" Type="Int32" DefaultValue="10" /> <asp:Parameter Name="MaximumRows" Type="Int32" DefaultValue="10" /> --%> </SelectParameters> </asp:ObjectDataSource> <asp:GridView ID="GridView1" runat="server" DataSourceID="ObjectDataSource1" AllowPaging="true" PageSize="10"></asp:GridView> <br /> <asp:Label runat="server" ID="lblCount"></asp:Label> </div> </form> </body> </html> When I set EnablePaging to false on the ODS, and add the commented out StartRowIndex and MaximumRows params in the markup, I get data so it really seems like the data layer is behaving as it should. There's code in code file to put the value of the GetMessagesCount call in the lblCount, and that always has a sensible value in it. I've tried breaking in the BLL and stepping through, and the backend is getting called, and it is returning what looks like the right information and data, but somehow between the ODS and the GridView it's vanishing. I created a mock data source which returned numbered rows of random numbers and attached it to this form, and the custom paging worked so I think my understanding of the technique is good. I just can't see why it fails here! Any help really appreciated. (EDIT .. here's the code behind). using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.UI; using System.Web.UI.WebControls; using System.ComponentModel; public partial class developer_PageTest : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { lblCount.Text = String.Format("Count = {0}", MessageTable.GetMessagesCount(112, null, null, null, null, null)) } }

  • Implementing Security on custom BCS/.net class?

    - by Michael Stum
    I'm implementing a custom BCS Model to get data from a backend system. As the backend uses it's own user management, I'm accessing it through a service account. All of this works well and allows me to pull data into SharePoint. However because it's channeled through the service account, everyone can access it, which is bad. Can anyone give me some tips which method to implement? The backend does not give me NT ACLs, but I wonder if I could just "fake" them somehow? (Essentially saying "This NT Group has Read Access" is good enough). I am aware of ISecurityTrimmer2 for Search Results, but ideally I want to cover security inside the BCS Model so that it applies to external lists as well. I want to avoid using Secure storage and mapping each individual user to the backend.
