  • Update database using restful ASP.NET MVC 1.0

    - by Mike
    We are building an MVC 1.0 application right now and using Linq - SQL for our DAL. Following the restful approach we have multiple action events depending on if you are updating or loading or what not. The two that I'm concerned with at this point are the edit and update action methods. Here is the signatures. public ActionResult Update(int customerId, int Id, AggregateModel viewModel) public ActionResult Edit(int customerId, int Id, AggregateModel viewModel) So the idea is that in the Edit method we load up our viewModel and pass it to the view. The user makes changes to the model and then posts back to the Update method. The first thing I could think of to do would be to get the viewModel from the database again, copy the changes in one by one from the posted back model and then submit it back. This would work but does seem clunky to me. What is the best way to insert those changes into the database at this point?

  • jQuery replacing an image inside a .net datalist

    - by user359409
    (submit said I was trying to post an image so I've changed image everywhere to ix I am trying to get jQuery to replace an ix inside a datalist. The original ix is the thumbnail ix of a product on a category page. The small ix I am clicking on are swatch ix for the different colors of a product. I can get it to work using a div tag around the ix tag inside the ItemTemplate. I don't need to use a div tag if I can get the imagesx to swap- I was just using it because that is sample code I found and it works for the first product in the category. <asp:HyperLink ID="ProductNav" runat="server" NavigateUrl='<%#Eval("NavigateUrl") %>'> <div id="ladiv" runat="server"> <asp:Ixx runat="server" ID="ProdThumb" /> </div> </asp:HyperLink> <asp:PlaceHolder ID="phSwatches" runat="server"></asp:PlaceHolder> The ProdThumb ix is added from the code behind and the swatches are added from the code behind swatches.Controls.Add(new LiteralControl("<table><tr>")); foreach(OptionChoice optionChoice in option.Choices) { string swatchThumbnail = string.Format("<ix ID=\"{0}\" src=\"{1}\" border=\"0\" class=\"{2}\" />","swatch" + optionChoice.OptionChoiceId.ToString(), ResolveUrl(optionChoice.ThumbnailUrl),"imgthumb"); swatches.Controls.Add(new LiteralControl("<td>")); swatches.Controls.Add(new LiteralControl(swatchThumbnail)); swatches.Controls.Add(new LiteralControl("</td>")); } swatches.Controls.Add(new LiteralControl("</tr></table>")); prodThumb.IxUrl = product.ThumbnailUrl; prodThumb.AlternateText = product.ThumbnailAltText; prodThumb.CssClass = "Thumbnail"; The jQuery is: $(function() { $("ix.imgthumb").click(function(e) { var t = $(this); var newImg = ''; $('#ladiv') .html($(newImg) ); }); }); </script> Both images are named similar, except the swatch contains "sws" and the larger one is the some only with "swl". I have spent several days searching but am not able to get it to work. If I try something like $("#<%=ladiv.ClientID %") the code can't find it. I appreciate any help.

    - by user1704379
    I am using Modal Popup in my MVC3 application it works fine but opens twice for a single Click on the link. The Modal pop is triggered from the 'Index' view of my Home Controller. I am calling a view 'PopUp.cshtml' in my modal popup. The related ActionMethod 'PopUp' for the respective view is in my 'Home' controller. Here is the code, Jquery code on layout.cshtml page, <script type="text/javascript"> $.ajaxSetup({ cache: false }); $(document).ready(function () { $(".openPopup").live("click", function (e) { e.preventDefault(); $("<div></div><p>") .attr("id", $(this).attr("data-dialog-id")) .appendTo("body") .dialog({ autoOpen: true, title: $(this).attr("data-dialog-title"), modal: true, height: 250, width: 900, left: 0, buttons: { "Close": function () { $(this).dialog("close"); } } }) .load(this.href); }); $(".close").live("click", function (e) { e.preventDefault(); $(this).dialog("close"); }); }); </script> cshtml code in 'PopUp.cshtml' @{ ViewBag.Title = "PopUp"; Layout = null; } <h2>PopUp</h2> <p> Hello this is a Modal Pop-Up </p> Call modal popup code in Index view of Home Controller, <p> @Html.ActionLink("Click here to open modal popup", "Popup", "Home",null, new { @class = "openPopup", data_dialog_id = "popuplDialog", data_dialog_title = "PopUp" }) </p> What am I doing wrong that the modal pop up opens twice ? Thanks in Advance !

  • Unique visitor counting in ASP.NET MVC

    - by Max
    I'd like to do visitor tracking similar to how stackoverflow does it.. By reading through numerous posts, I've figured out some details already: Count only 1 IP hit per 15 minutes (if anonymous) Count only 1 unique user-Login (per day?) Now that leaves the question of the real implementation.. Should I log the two factors live into a table (and increase count) | IP | timestamp | pageurl | Or do the counting AFTERWARDS (e.g. using IIS log files - which don't include the user, right? I know there're some similar posts outside, but NONE really has a great solution in my opinion yet..

  • resource embedding in asp.net

    - by Mike
    I have a project which needs to generate PDF documents. I am using iTextSharp. I have a pdf which needs to be read and then appended to. To read the pdf document, I'm using PdfReader(), which accepts many forms, but I can't figure out how to reference a pdf in my webapplication to PdfReader. My host does not allow Binary Serialization (apparently that's bad), so I don't think I can load from an embedded resource. I've tried just using PdfReader("report.pdf"), but it keeps throwing an exception telling me that the file isn't found. I've tried putting the file in the bin directory, root directory, in the same directory as the class, but this still doesn't work. It works if I use a fully qualified path to the pdf document, but I can't use that when I upload it to my hosting provider. Does anyone have any suggestions on how I should do this? Thanks

  • WCF publish/subscribe service, and ASP.NET MVC client

    - by d3j4vu
    I managed to develop a custom WCF service, using the publish / subscribe model, and hosted inside a managed windows service. Everything's working. I developed an interface as the service contract implementing a method definition marked as a non-one way operation contract (OperationContract(IsOneWay = false)]. This, to make possible returns an instance of a custom class derived from System.Web.Mvc.ActionResult. In the MVC app, event fires ok. It wraps inside an action method, (just the one defined in the interface), but, and this is my current problem, i believe that something relative to the execution context of the windows service (and the hosted wcf counterpart) blocks the execution of the action method in the MVC app. This is what i have until now (some pieces ripped off just to be more clear): /// Method definition for the contract's service. Maps to a MVC ActionMethod. [OperationContract(IsOneWay = false)] ActionResult Imagen(string data, CustomActionResult result); The class to hold an ActionResult derived class instance: public class ServiceEventArgsMvc : ServiceEventArgs { /// <summary> /// /// </summary> public CustomActionResult Result { get; set; } } And the code in the MVC client app: /// <summary> /// Just a simple class to hold an abstract ActionResult derived class instance. /// </summary> public ActionResult Image(string data, CustomActionResult result) { ViewData["data"] = data; return View(); } Ok. ActionMethod sucessfully executes...but when it's done (and usually expected obtain a reditection to a View named Image, like the action method), the WCF service throws a Timeout exception, making clear that he's still waiting for a response from the MVC client. The response never arrives, so the MVC app never finish his work (redirect to the "Image" view as expected). Any ideas?. Guess i'm missing something very simple, but i don't know what it could be. This is drivin' me nuts.

  • size of structures in .NET

    - by redpaladin
    My problem is very simple. My problem is to send a structure between a program in C to a C# program. I made a struct in C#: public struct NetPoint { public float lat; // 4 bytes public float lon; // 4 bytes public int alt; // 4 bytes public long time; // 8 bytes } Total size of the struct must be 20 bytes. When I do a sizeof() of this struct: System.Diagnostics.Debug.WriteLine("SizeOf(NetPoint)=" + System.Runtime.InteropServices.Marshal.SizeOf(new NetPoint())); The debug console shows: SizeOf(NetPoint)=24 But I expected to have 20 bytes. Why do I see a difference?

  • how to protect an imported win32 dll into a .net application from memory issues

    - by Eric
    I have a c# application that needs to use a legacy win32 dll. The dll is almost its own app, it has dialogs, operations with hardware, etc. When this dll is imported and used, there are a couple of problems that occur: Dragging a dialog (not a windows system dialog, but one created by the dll) across the managed code app causes the UI to not repaint. Further it generates a system out of memory exception from various ui controls. The performance is incredibly slow. There seems to be no way to unload the dll so the memory never gets cleaned up. When we close our managed app, we get another memory exception. At the moment we import each method call as such: [DllImport("dllname.dll", EntryPoint = "MethodName", SetLastError = true, CharSet = CharSet.Auto, ExactSpelling = true, CallingConvention = CallingConvention.StdCall)]

  • Fix a font size for .NET GUI

    - by Dmi
    Hi, Depending on the font settings (DPI and such) on the user's computers, I can have text become too big to fit in a button and moves down to the next line (wrap), so if it is a small button that says "Do xyz", it will only show "Do" unless I increase the height on the user's computer, but it looks fine on mine. Is there any way to force it to stick to original font size?

  • Validating primitive types in ASP.NET MVC

    - by Alex
    I've implemented the following classes to validate data public abstract class Validated { public bool IsValid { get { return (GetRuleViolations().Count() == 0); } } public abstract IEnumerable<RuleViolation> GetRuleViolations(); } public partial class User: Validated { public override IEnumerable<RuleViolation> GetRuleViolations() { if (this.Age < 1) yield return new RuleViolation("Age can't be less than 1"); } } It works great! When the form is submitted I just do if (user.IsValid == false) blah... But I still need to validate that the Age is an integer int a = 0; if (!int.TryParse(age, out a)) { error = "Not integer"; // ... } How can I move this to my model?

  • ASP.NET MVC 2 Model object validation

    - by Jimmy
    Hey guys, I'm trying to validate a model object outside of the context of ModelState within a controller, I currently have a parser that creates model objects from an excel file and I want to be able to report how many entries were added to the database and how many failed, is there a way to validate a model object on its data annotations outside of model binding? I'm looking for something similar to the rails model method of model.valid? or a way for me to implement that myself. My current solution is just manually checking if a few key fields are present but this duplicates requirements between my model class and its metadata, there has to be a better way to hook into the model validation checking that is done by mvc 2. Thanks

  • Help me convert .NET 1.1 Xml validation code to .NET 2.0 please.

    - by Hamish Grubijan
    It would be fantastic if you could help me rid of these warnings below. I have not been able to find a good document. Since the warnings are concentrated in just the private void ValidateConfiguration( XmlNode section ) section, hopefully this is not terribly hard to answer, if you have encountered this before. Thanks! 'System.Configuration.ConfigurationException.ConfigurationException(string)' is obsolete: 'This class is obsolete, to create a new exception create a System.Configuration!System.Configuration.ConfigurationErrorsException' 'System.Xml.XmlValidatingReader' is obsolete: 'Use XmlReader created by XmlReader.Create() method using appropriate XmlReaderSettings instead. http://go.microsoft.com/fwlink/?linkid=14202' private void ValidateConfiguration( XmlNode section ) { // throw if there is no configuration node. if( null == section ) { throw new ConfigurationException("The configuration section passed within the ... class was null ... there must be a configuration file defined.", section ); } //Validate the document using a schema XmlValidatingReader vreader = new XmlValidatingReader( new XmlTextReader( new StringReader( section.OuterXml ) ) ); // open stream on Resources; the XSD is set as an "embedded resource" so Resource can open a stream on it using (Stream xsdFile = XYZ.GetStream("ABC.xsd")) using (StreamReader sr = new StreamReader(xsdFile)) { vreader.ValidationEventHandler += new ValidationEventHandler(ValidationCallBack); vreader.Schemas.Add(XmlSchema.Read(new XmlTextReader(sr), null)); vreader.ValidationType = ValidationType.Schema; // Validate the document while (vreader.Read()) { } if (!_isValidDocument) { _schemaErrors = _sb.ToString(); throw new ConfigurationException("XML Document not valid"); } } } // Does not cause warnings. private void ValidationCallBack( object sender, ValidationEventArgs args ) { // check what KIND of problem the schema validation reader has; // on FX 1.0, it gives a warning for "<xs:any...skip" sections. Don't worry about those, only set validation false // for real errors if( args.Severity == XmlSeverityType.Error ) { _isValidDocument = false; _sb.Append( args.Message + Environment.NewLine ); } }
