  • ASP.NET Bind to IEnumerable

    - by JFoulkes
    Hi, I'm passing a the type IEnumerable to my view, and for each item I output a html.textbox to enter the details into. When I post this back to my controller, the collection is empty and I can't see why. public class Item { public Order Order { get; set; } public string Title { get; set; } public double Price { get; set; } } My Get method: public ActionResult AddItems(Order order) { Item itemOne = new Item { Order = order }; Item itemTwo = new Item { Order = order, }; IList<Item> items = new List<Item> { itemOne, itemTwo }; return View(items); } The View: <% int i = 0; foreach (var item in Model) { %> <p> <label for="Title">Item Title:</label> <%= Html.TextBox("items[" + i + "].Title") %> <%= Html.ValidationMessage("items[" + i + "].Title", "*")%> </p> <p> <label for="Price">Item Price:</label> <%= Html.TextBox("items[" + i + "].Price") %> <%= Html.ValidationMessage("items[" + i + "].Price", "*")%> </p> <% i++; } %> The POST method: [AcceptVerbs(HttpVerbs.Post)] public ActionResult AddItems(IEnumerable<Item> items) { try { return RedirectToAction("Index"); } catch { return View(); } } At the moment i just have a breakpoint on the post method to check what i'm gettin back.

  • Windows Service And Thread Programming .NET

    - by Raghu
    I have developed windows service to process files whose records will be stored in database. When windows service finds a file it creates a thread and assigns each file to one thread. I have not used Thread Pool. I wanted to know when windows service is stopped, then how to identify how many threads are running and whether they are complete. If all the threads are executed then windows service can be stopped successfully. Otherwis windows service should wait until all threads are executed or aborted. How to implement this.

  • Load an Assembly from Bin in ASP.NET

    - by Pete Michaud
    I have a file name, like "Foo.dll," for a library that I know is in the bin directory. I want to create an Assembly object for it. I'm trying to instantiate this object from a class that's not a page, so I don't have the Request object to get the path. How do I get the path I need to use Assembly.Load()?

  • get length of data sent over network to TCPlistener/networkstream vb.net

    - by Jonathan.
    It seems the most obvious thing, but I just can't work out how to get the length of bytes sent over a network using a TCPClient and TCPListener? This is my code so far: 'Must listen on correct port- must be same as port client wants to connect on. Const portNumber As Integer = 9999 Dim tcpListener As New TcpListener(IPAddress.Parse("192.168.2.7"), portNumber) tcpListener.Start() Console.WriteLine("Waiting for connection...") 'Accept the pending client connection and return 'a TcpClient initialized for communication. Dim tcpClient As TcpClient = tcpListener.AcceptTcpClient() Console.WriteLine("Connection accepted.") ' Get the stream Dim networkStream As NetworkStream = tcpClient.GetStream() '' Read the stream into a byte array I need to get the length of the networkstream to set the size of the array of bytes I'm going to read the data into. But the networkStream.length is unsupported and does not work and throws an Notsupportedexception. The only other way I can think of is to send the size of the data before sending the data, but this seems the long way round.

  • Membership.ValidateUser always returns false after upgrade to VS 2010 / .NET 4.0

    - by nw
    Not sure whether this pertains to VS 2010 or to the upgraded framework, but... we are using the Oracle membership provider to authenticate users. Prior to the upgrade everything worked fine, but now Membership.ValidateUser(user, password) returns false despite valid credentials. There is no exception thrown, so it's hard to determine what the problem might be. The website administration tool in VS 2010 is still able to manage users and roles (more or less), so I have no reason to question connectivity. What might the problem be?

  • How Pick a Column Value from a ListView Row - C#.NET

    - by peace
    How can i fetch the value 500 to a variable from the selected row? One solution would be to get the row position number and then the CustomerID position number. Can you please give a simple solution. SelectedItems means selected row and SubItems means the column values, so SelectedItem 0 and SubItem 0 would represent the value 500. Right? This is how i populate the listview: for (int i = 0; i < tempTable.Rows.Count; i++) { DataRow row = tempTable.Rows[i]; ListViewItem lvi = new ListViewItem(row["customerID"].ToString()); lvi.SubItems.Add(row["companyName"].ToString()); lvi.SubItems.Add(row["firstName"].ToString()); lvi.SubItems.Add(row["lastName"].ToString()); lstvRecordsCus.Items.Add(lvi); }

  • Anyone using ASP.NET MembershipProvider with Nhibernate?

    - by JLago
    Hi, I'm trying to implement Membership controls in a mvc 2 application and i'm having trouble dealing with the MembershipUser class. I have my own data store (in Postgresql) and I'm using Nhibernate to deal with it from C#. The thing is, I have my own user class, but I can't use it with any provider I found that implements Membership, because all the functions return the predefined MembershipUser class and cannot return my own. I'm losing my mind here, is there any way i can work with this, or should I implement everything myself? thanks in advance!

  • ASP.NET MVC Default URL View

    - by Moose Factory
    I'm trying to set the Default URL of my MVC application to a view within an area of my application. The area is called "Common", the controller "Home" and the view "Index". I've tried setting the defaultUrl in the forms section of web.config to "~/Common/Home/Index" with no success. I've also tried mapping a new route in global.asax, thus: routes.MapRoute( "Area", "{area}/{controller}/{action}/{id}", new { area = "Common", controller = "Home", action = "Index", id = "" } ); Again, to no avail.

  • Saving contents of ApplicationState in ASP.Net (MVC)

    - by Saqib
    I have an internal app used to edit XML files on disk. The XML files are loaded into an object model which is stored in ApplicationState. I need to save this data. The one option is to do this every time the user changes some data. However, this seems a bit inefficient - writing the data out to disk each time a change is made. Instead, is it possible to be notified whenever the user closes their browser, plus just before the web server exits? Thus, the data would be saved each time a session ends, plus when the computer shuts down, etc. I thought that Application_End(), Application_Error() and Session_End() in Global.asax would provide this, but these methods don't seem to be called.

  • Global hotkey capture in VB.net

    - by ggonsalv
    I want to have my app which is minimized to capture data selected in another app's window when the hot key is pressed. My app definitely doesn't have the focus. Additionally when the hot key is pressed I want to present a fading popup (Outlook style) so my app never gets focus. At a minimum I want to capture the Window name, Process ID and the selected data. The app which has focus is not my application? I know one option is to sniff the Clipboard, but are there any other solutions. This is to audit the rate of data-entry in to another system of which I have no control. It is a mainframe emulation client program(attachmate). The plan is complete data entry in Application X. Select a certain section of the screen in App X which is proof of data entry (transaction ID). Press the Magic Hotkey, which then 'sends' the selection to my App. From System.environment or system.Threading I can find the Windows logon. Similiarly I can also capture the time. All the data will be logged to SQL. Once Complete show Outlook style pop up saying the data entry has been logged. Any thoughts.

  • Easiest way to specify the selected option to a dropdown list in ASP.NET MVC

    - by sdr
    I have a list of options (IEnumerable< SelectListItem ) in my model that I want to use in multiple dropdowns in my view. But each of these dropdowns could have a different selected option. Is there an easy way to simply specfiy which should be selected if using the Html.DropDownList helper? At this point, the only way I can see is to generate the html myself and loop through the list of options like so: <% for(int i=0; i<10; i++) { %> <select name="myDropDown<%= i %>"> <% foreach(var option in Model.Options) { %> <option value="<%= Html.Encode(option.optValue) %>" <%if(ShouldBeSelected(i)) {%> selected="selected"<% } %>><%= Html.Encode(option.optText) %></option> <% } %> </select> <% } %>

  • VB.NET 2.0 - StackOverflowException when using Thread Safe calls to Windows Forms Controls

    - by LamdaComplex
    I have a Windows Forms app that, unfortunately, must make calls to controls from a second thread. I've been using the thread-safe pattern described on the http://msdn.microsoft.com/en-us/library/ms171728.aspx. Which has worked great in the past. The specific problem I am having now: I have a WebBrowser control and I'm attempting to invoke the WebBrowser.Navigate() method using this Thread-Safe pattern and as a result I am getting StackOverflow exceptions. Here is the Thread-Safe Navigate method I've written. Private Delegate Sub NavigateControlCallback(ByRef wb As WebBrowser, ByVal url As String) Private Sub AsyncNavigate(ByRef wb As WebBrowser, ByVal URL As String) Try If wb.InvokeRequired Then Dim callback As New NavigateControlCallback(AddressOf AsyncNavigate) callback(wb, url) Else wb.Navigate(url) End If Catch ex As Exception End Try End Sub Is there a Thread-Safe way to interact with WinForms components without the side effect of these StackOverflowExceptions?

  • Unit testing MVC.net Redirection

    - by Dan
    How do I Unit Test a MVC redirection? public ActionResult Create(Product product) { _productTask.Save(product); return RedirectToAction("Success"); } public ActionResult Success() { return View(); } Is Ayende's approach still the best way to go, with preview 5: public static void RenderView(this Controller self, string action) { typeof(Controller).GetMethod("RenderView").Invoke(self,new object[] { action} ); } Seems odd to have to do this, especially as the MVC team have said they are writing the framework to be testable.

  • ASP.net MVC 3 adding arbitrary text to the end of an ActionLink

    - by infensus
    Hi I have a question about Html.ActionLink. Imagine: @Html.ActionLink(item.title, "Singlet", new { id = item.blog_id }) produces http://[url]/[controller]/Singlet/[id] But what if I want to suffix some more arbitrary data at the end? For example: http://[url]/[controller]/Singlet/[id]/#comments To jump to the comments div. I know I can just make the string myself with something like: @( new HtmlString(String.Format("<a href=\"Blog/Singlet/{0}/#comments\">link to comments</a>", item.blog_id)) ) But I am hoping there is a cleaner way, perhaps with ActionLink? Thanks

  • ASP.Net MVC null reference exception with TextArea name

    - by kingrichard2005
    Hello, I have a TextArea html helper method I'm calling in a foreach loop. Basically, when I initially load the View it works fine, but when i reload the View and load postback data, the same TextArea throws a NullReferencException and yet the variable I'm using in the TextArea as the name of the TextArea is not null. I've attached a picture below for demonstration: Sorry if it's difficult to see, the blue arrow below is pointing to the variable used to name the TextArea. Again, it works on initial load, but it errors out on postback when the page is reloaded. I'm not sure what's going on.

  • asp.net mvc xval validation

    - by mctayl
    Hi there I am using xval for the first time, it seems to work fine for required fields, However I am having some issues first of all it does not seem to validate booleans and also client validation is not working for me, this is not a major issue for me, the one that I really need to work is the stringlength property. It seems to do something because the form is not posted when the string length is exceeded, however no error message is displayed to the user which is obviously not what I want, has anyone been able to do this successfully? My model goes like this using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.ComponentModel.DataAnnotations; namespace PitchPortal.Core { public class DocumentMetadata { //[Required] // public bool visibility { get; set; } [Required,StringLength(10, ErrorMessage = "title is too long")] public string title { get; set; } [Required, StringLength(10, ErrorMessage = "description is too long")] public string description { get; set; } [Required, StringLength(10, ErrorMessage = "summary is too long")] public string summary { get; set; } } } the html goes like this <div id="results" title="Upload results"/> <form id="myForm" action="<%=Url.Action("New") %>" method="post" enctype="multipart/form-data"> <% Html.EnableClientValidation(); %> <%= Html.ValidationSummary() %> <table> <tr> <td> <%=Html.Label("File")%></td> <td> <input type="file" id="file1" name="fileUpload" /> <br /> <%=Html.SubmitButton<DocumentController>(x => x.Upload(), "GetImage", "")%> </td> <td> <%=Html.ValidationMessage("file1")%> </td> </tr> <tr> <td> <%=Html.Label("Visible")%></td> <td> <%= Html.RadioButton( "visibility",true,true) %>true <%= Html.RadioButton("visibility", false)%>false </td> <td> <%= Html.ValidationMessage("visibility")%> </td> </tr> <tr> <td> <%=Html.Label("Title")%></td> <td> <%=Html.TextBox("doc.title")%></td> <td> <%= Html.ValidationMessage("doc.title")%></td> </tr> <tr> <td> <%=Html.Label("Description")%></td> <td><%= Html.TextArea("doc.description")%></td> <td><%= Html.ValidationMessage("doc.description")%></td> </tr> <tr> <td> <%=Html.Label("Summary")%></td> <td> <%= Html.TextArea("doc.summary")%></td> <td> <%= Html.ValidationMessage("doc.summary")%></td> </tr> <tr> <td> <%=Html.Label("Filetype")%></td> <td> <%= Html.DropDownList("Filetype_id", (IEnumerable<SelectListItem>)ViewData.Model.AllFiletypesList)%> </td> <td> <%= Html.ValidationMessage("doc.Filetype_id")%> </td> </tr> <tr> <td> <%=Html.Label("Category")%></td> <td><%= Html.DropDownList("cat.parent_id", (IEnumerable<SelectListItem>)ViewData.Model.AllCategoriesList, "-please select item-", new { className = "unselected" })%> </td> <td><%= Html.ValidationMessage("cat.parent_id")%> </td> </tr> <% if (Session["TempFolder"] == null) { for (int i = 1; i < 6; i++) { %> <tr> <td> <%=Html.Label("Shot "+i.ToString()) %> </td> <td><input type="file" id="image_<%= i.ToString() %>" name="image_<%= i.ToString() %>" /></td> </tr> <% } }%> <tr> <td><input type="submit" value="save"/></td> </tr> </table> </form> </div>
