  • ASP.NET MVC Image refreshing

    - by user295541
    Hi, I have an Employee object which has an image property. Image class contains image metadata as image caption, and image file name. If I upload a new image for an employee on async way without full post back the new image is not appeared on the page. I use GUID to name the image file to avoid the page caching. I do the image modifying the following way: ctrEmployee employee = Repository.Get(PassedItemID); if (employee.ctrImage != null) { string fullFileName = serverFolder + employee.ctrImage.FileName; FileInfo TheFile = new FileInfo(fullFileName); if (TheFile.Exists) { TheFile.Delete(); } fileName = Guid.NewGuid() + ".jpg"; employee.ctrImage.FileName = fileName; } resizedBmp.Save(string.Format("{0}{1}", serverFolder, fileName), System.Drawing.Imaging.ImageFormat.Jpeg); Repository.Edit<ctrEmployee>(employee); ImageID = employee.Image.Value; return PartialView(UserControlPaths.Thumbnail, new ThumbnailDataModel(employee.Image.Value, 150, 150)); The partial view has an image tag which gets the saved image url string which is a GUID. Anybody has an idea what I do wrong?

  • asp.net ajax, change asp:image imageurl

    - by maxxxee
    I have an update panel within which a sortable grid is present. While sorting, I have to change an image which shows the sort direction. The sort is an ajax operation initiated by a linkbutton for each column. Everything works fine except the image control. I am able to toggle visible property to show and hide it but, not able to change the ImageUrl property. imagesort.ImageUrl = "~/images/asc.jpg"; imagesort.Visible = true; The above code shows the image but the image is always the imageurl given in the markup not what is set in the code. If imageurl is not specified in the markup, no image(broken image) is shown irrespective of the above code.

  • Have VB.Net 2010 ErrorProvider Fire on Tabbing Out of BindingSource TextBox on a WinForm

    - by OneSource
    I have a TextBox control on a Windows Form that uses a DataSource custom object as its BindingSource. I have associated an ErrorProvider with the BindingSource like so: Dim dobExample As New DOExample ExampleBS.DataSource = dobExample epExample.DataSource = ExampleBS The ErrorProvider fires if I type a blank space in the TextBox and then press Tab to move to the next control, which is correct. But it doesn't fire if I just press Tab without entering anything. I want the ErrorProvider to show the Error, even if the TextBox is empty and not just validate when there is text in the TextBox. How do I accomplish this? As an additional bit of info, when I execute the following statement: epDOContact.GetError(TextBox) an empty string is returned even though the TextBox is empty when it is required to be present.

  • Working with DataBinding and Page_Load in ASP.NET MVP

    - by Joel
    I'm using WebForms MVP to create some simple reporting applications. Most of these applications consist of a few search criteria inputs and a ComponentArt datagrid that I'm populating with data from the database. Most of the markup is in a UserControl, which is in a content page with a master page. My problem is that the control's Page_Load event is firing before the control events that caused the postback in the first place. Basically, the user clicks the search button, and Page_Load is fired BEFORE Search_Click. This is messing with the databinding scheme I've been using. So that's the question: Why is my Page_Load event firing before the event handler, and what can I do about it? I don't THINK this problem is related to WebForms MVP or ComponentArt, but obviously I could be wrong. Thanks.

  • asp.net mvc log4postsharp

    - by mike
    Hi Iam trying to use log4post sharp for logging purposes, As far as Iam aware I have followed the instructions to get this up and running, I have not installed postsharp, rather I got the library files and midified my cs proj file to target those file, I have also tried installing postsharp on my machine. In either case I end up with this error Error 5 The plug-in "Log4PostSharp" required by the type "Log4PostSharp.LogAttribute" was not found. I have tried googling this and it seems there is no trace of this issue anywhere on the web. One difference between my implementation with other examples is that the postsharp dll that they use is PostSharp.public, mine is just PostSharp. I have tried searching for the former dll but cannot find it anywhere, the download only contains PostSharp.dll. I feel this may be the issue as I have followd all the insturctions to the letter to get this up and running. Any Ideas People?

  • Ajax call with jQuery in ASP.NET MVC does not pass parameters

    - by desmati
    The Route is: routes.MapRoute( "Ajax", // Route name "BizTalk/Services/{action}", // URL with parameters new { // Parameter defaults controller = "BizTalk" } ); My Controller is: public JsonResult AjaxTest(string s, int i, bool b) { return Json("S: " + s + "," + "I: " + i + "," + "B: " + b); } My jQuery Code: $(document).ready(function() { $("#btn_test").click(function() { var s = "test"; var i = 8; var b = true; $.ajax({ type: "POST", cache: false, url: "/BizTalk/Services/AjaxTest", data: { i: i, s: s, b: b }, contentType: "application/json; charset=utf-8", dataType: "json", success: function(msg) { } }); }); });

  • C# .NET: Descending comparison of a SortedDictionary?

    - by Rosarch
    I'm want a IDictionary<float, foo> that returns the larges values of the key first. private IDictionary<float, foo> layers = new SortedDictionary<float, foo>(new DescendingComparer<float>()); class DescendingComparer<T> : IComparer<T> where T : IComparable<T> { public int Compare(T x, T y) { return -y.CompareTo(x); } } However, this returns values in order of the smallest first. I feel like I'm making a stupid mistake here. Just to see what would happen, I removed the - sign from the comparator: public int Compare(T x, T y) { return y.CompareTo(x); } But I got the same result. This reinforces my intuition that I'm making a stupid error. This is the code that accesses the dictionary: foreach (KeyValuePair<float, foo> kv in sortedLayers) { // ... } UPDATE: This works, but is too slow to call as frequently as I need to call this method: IOrderedEnumerable<KeyValuePair<float, foo>> sortedLayers = layers.OrderByDescending(kv => kv.Key); foreach (KeyValuePair<float, ICollection<IGameObjectController>> kv in sortedLayers) { // ... } UPDATE: I put a break point in the comparator that never gets hit as I add and remove kv pairs from the dictionary. What could this mean?

  • Entity Framework Update Error in ASP.NET Mvc with related entity

    - by Barry
    I have run into a problem which have searched and tried everything i can to find a solution but to no avail. I am using the same repository and context throughout the process I have a booking entity and a userExtension Entity Below is my image i then get my form collection back from my page and create a new booking public ActionResult Create(FormCollection collection) { Booking toBooking = new Booking(); i then do some validation and property assignment and find an associated BidInstance toBooking.BidInstance = bid; i have checked and the bid is not null. finally i get the user extension file from the Current IPRINCIPAL USER as below UserExtension loggedInUser = m_BookingRepository.GetBookingCurrentUser(User); toBooking.UserExtension = loggedInUser; The Code to do the getUserExtension is : public UserExtension GetBookingCurrentUser(IPrincipal currentUser) { var user = (from u in Context.aspnet_Users .Include("UserExtension") where u.UserName == currentUser.Identity.Name select u).FirstOrDefault(); if (user != null) { var userextension = (from u in Context.UserExtension.Include("aspnet_Users") where u.aspnet_Users.UserId == user.UserId select u).FirstOrDefault(); return userextension; } else{ return null; } } It returns the userextension fine and assigns it fine. i originally used the aspnet_users but encountered this problem so tried to change it to the extension entity. as soon as i call the : Context.AddToBooking(booking); Context.SaveChanges(); i get the following exception and im completely baffled by how to fix it Entities in 'FutureFlyersEntityModel.Booking' participate in the 'FK_Booking_UserExtension' relationship. 0 related 'UserExtension' were found. 1 'UserExtension' is expected. then the final error that comes to the front end is: Metadata information for the relationship 'FutureFlyersModel.FK_Booking_BidInstance' could not be retrieved. Make sure that the EdmRelationshipAttribute for the relationship has been defined in the assembly. Parameter name: relationshipName.. But both the related entities are set in the booking entity passed thruogh PLEASE HELP Im at wits end with this

  • Handling button click in ASP.NET MVC 2 RTM

    - by Leniel Macaferi
    I have a View in which the user is able to upload a file to the server. In this view I also have 2 buttons: one to Upload a file and other to Download the last file imported. In my Controller I created 2 action methods: Import and Export. How could I manage to redirect each button click to the proper action method in my Controller? I have tried Html.ActionLink: <%= Html.ActionLink("Upload", "Import", "OracleFile")%> <%= Html.ActionLink("Download", "Export", "OracleFile")%> Html.ActionLink didn't do the trick. The action links were taking me to the right Action methods but they were generating a GET request. This way Request.Files.Count = 0. I need a POST request.

  • Conditional required field validation in an ASP.net ListView

    - by Jim Dagg
    I'm having a heck of a time trying to figure out how to implement validation in a ListView. The goal is to require the user to enter text in the comments TextBox, but only if the CheckBox is checked. Downside is that these controls are in the EditTemplate of a ListView. Below is a snippet of the relevant code portion of the EditTemplate: <tr style="background-color: #00CCCC; color: #000000"> <td> Assume Risk? <asp:CheckBox ID="chkWaive" runat="server" Checked='<%# Bind("Waive") %>' /> </td> <td colspan="5"> <asp:RequiredFieldValidator ID="RequiredFieldValidator1" runat="server" ErrorMessage="Comments required" ControlToValidate="txtComments" /> <asp:TextBox Width="95%" ID="txtComments" runat="server" Text='<%# Eval("Comment") %>'></asp:TextBox> </td> <td> <asp:Button ID="btnSave" runat="server" Text="Save" CommandName="Update" Width="100px" /> </td> </tr> Is there a way to do conditional validation using this method? If not, is there a way I could validate manually in the ItemUpdating event of the Listview, or somewhere else, and on a failure, alert the user of the error via a label or popup alert?

  • Return ArrayList from .net web service to android application using kSoap

    - by benjamin schultz
    My web service is returning quite a bit of data, so i'm storing it in an arraylist and returning that to my application. I don't know whether or not this is the preferred method or not. When the arraylist is returned and displayed in my application, it also displays the arraylists "anyType" section. I'm new to this whole process so i'm sure i'm missing something somewhere or going about this incorrectly. Can anyone point me in the right direction please?

  • DefaultSchedulerService in ASP.NET application

    - by Samir P
    Hi, My project has a requirement to implement look-ahead caching i.e. triggering another request on invokation of a specific request. The following details in short the implementation - HttpModule parses the SOAPRequest and matches entry in a configuration file for look-ahead candidate. If the request matches, it prepares the Parameters dictionary and starts appropriate workflow. Single workflow runtime is used across all requests is ensured through initializing the runtime instance at Application_Start event and stored in Application Dictionary. Using persistence service and DefaultScheduler service. We can't implement windows service model, as current requirement mandates passing the SOAPRequest parameters as arguments. ManualSchedulerService is not in contention due to synchronous nature of it's actual behaviour. Still the performance is pretty bad and product team is not happy. Can anybody suggest me better solution? Thanks, Samir

  • .Net ListView and System's Icon Size

    - by WhoaNow
    I have a ListView using the LargeIcon View mode with some 64x64 thumbnails. The problem is that the padding between ListViewItems is somehow based on the system's Icon size value (Display Properties Appearance Advanced Icon). The default for XP seems to be 32 and the ListView and its thumbnails look fine, but with higher Icon sizes, the items are spaced out horrendously. Is there any way to override this behavior and force it to use the same spacing?

  • doofus ASP.Net master page scrollbar question

    - by Stephen Falken
    Like happens to all of us sometimes, I inherited some crappy code I have to fix. We need to center our pages on widescreen machines, so we have a master page layout div like so: .MasterLayout { width:1100px; height: 100%; position:absolute; left:50%; margin-left:-550px; vertical-align:top; } I removed most of the detailed attributes for readability here, but here's how the table for the master page is laid out: <table border="0" cellpadding="0" cellspacing="0" style="width: 100%;"> <tr> <td style="width: 100%" align="center" colspan="2"> </td> </tr> <tr> <td colspan="2" style="height: 20px; background-color: #333;"> <asp:SiteMapPath/> </td> </tr> <tr> <td style="width: 86px; height: 650px; background-color: #B5C7DE; margin: 6px;" valign="top"> <asp:Menu /> <asp:SiteMapDataSource /> </td> <td style="background-color:#ffffff; margin:5px; width:1000px;" valign="top"> <asp:contentplaceholder id="ContentPlaceHolder1" runat="server"/> </td> </tr> </table> When resizing the browser window, the horizontal scrollbar only reaches as far as the left edge of the <asp:contentplaceholder/> control, and the <asp:menu/> that's in the 86px wide <td> is hidden. How can I fix this problem? THANKS IN ADVANCE
