  • No postback on any button click on ASP.NET 4.0 application

    - by Ashish Gupta
    The weird thing is If there is a javascript onClick() on a button, postback works otherwise, there is no postback. This was working very recently. I am not sure what recent changes made to the application made this happening throughout the site. The solution suggested by this link does not work as well (that link is applicable to .NET 1.1 though). Any idea whats going on?

  • Advanced ASP.NET Gridview Layout

    - by chief7
    So i had a feature request to add fields to a second table row for a single data row on a GridView. At first, I looked at extending the functionality of the GridView but soon realized this would be a huge task and since I consider this request a shim for a larger future feature decided against it. Also want to move to MVC in the near future and this would be throw away code. So instead I created a little jquery script to move the cell to the next row in the table. $(document).ready(function() { $(".fieldAttributesNextRow").each(function() { var parent = $(this).parent(); var newRow = $("<tr></tr>"); newRow.attr("class", $(parent).attr("class")); var headerRow = $(parent).parent().find(":first"); var cellCount = headerRow.children().length - headerRow.children().find(".hide").length; newRow.append($(this).attr("colspan", cellCount)); $(parent).after(newRow); }) }); What do you think of this? Is this a poor design decision? I am actually quite pleased with the ease of this solution. Please provide your thoughts.

  • Deselect dates in ASP.NET Calendar Control

    - by yomismo
    I'm trying to select and de-select dates on a C# Web Calendar control. The problem I have is that I can select or deselect dates except when there is only a single date selected. Clicking on it does not trigger the selection changed event, so Ineed to do something on the dayrender event but I'm not sure what or how. Edit: Added the Pre_Render event code. This seems to work now, however it seems a little bit erratic,e.g. select date A : OK Select date B :OK deselect them both: OK select date A: Does not work, need to select it twice deselect date A : Ok Select Date C: dates A and c are selected @John Yes, I am aware that the control is part of the .NET 2.0 framework and nothing to do with C# per se. Code so far: public static List<DateTime> list = new List<DateTime>(); protected void Calendar1_DayRender(object sender, DayRenderEventArgs e) { if (e.Day.IsSelected == true) { list.Add(e.Day.Date); } Session["SelectedDates"] = list; } protected void Calendar1_SelectionChanged(object sender, EventArgs e) { DateTime selection = Calendar1.SelectedDate; if (Session["SelectedDates"] != null) { List<DateTime> newList = (List<DateTime>)Session["SelectedDates"]; foreach (DateTime dt in newList) { Calendar1.SelectedDates.Add(dt); } if (searchdate(selection, newList)) { Calendar1.SelectedDates.Remove(selection); } list.Clear(); } } public bool searchdate(DateTime date, List<DateTime> dates) { var query = from o in dates where o.Date == date select o; if (query.ToList().Count == 0) { return false; } else { return true; } } protected void Calendar1_PreRender(object sender, EventArgs e) { if (Calendar1.SelectedDates.Count == 1) { foreach (DateTime dt in list) { if (searchdate(dt, list) && list.Count == 1) { Calendar1.SelectedDates.Clear(); break; } } } }

  • ASP.NET MVC Cookie loses value when page is changed

    - by Jova
    When a user logs in to my site, I create a cookie with some info in it. However, whenever they change page from logging in, the cookie loses it's value. Cookie is still there but it's empty. I've checked my code and the cookie doesn't get rewritten by anything I've done. Does anyone have any idea to why the cookie becomes empty when the page is changed?

  • paging helper asp.net mvc

    - by csetzkorn
    Hi, I have implemented a paging html helper (adapted from steven sanderson's book). This is the current code: public static string PageLinks(this HtmlHelper html, int currentPage, int totalPages, Func pageUrl) { StringBuilder result = new StringBuilder(); for (int i = 1; i <= totalPages; i++) { TagBuilder tag = new TagBuilder("a"); tag.MergeAttribute("href", pageUrl(i)); tag.InnerHtml = i.ToString(); if (i == currentPage) tag.AddCssClass("selectedPage"); result.AppendLine(tag.ToString()); } return result.ToString(); } This produces a bunch of links to each page of my items. If there are many pages this can be a bit overwhelming. I am looking for a similar implementation which produces something less overwhelming like this: where 6 is the current page. I am sure someone must have implemented something similar ... before I have to re-implement the wheel. Thanks. Christian

  • ASP.NET Theme stylesheet rendering

    - by Dan Appleyard
    When a page with theme is rendered, the stylesheets link tags in the given theme are rendered right before the closing head tag. Does anyone know of a way to change that? Is there a way that I could have those tags be placed right after the opening head tag? Thanks!

  • abandon session in asp.net on browser close..kill session cookie

    - by Tuviah
    So I have a website where I use session start and end events to track and limit open instances of our web application, even on the same computer. On page unload i call a session enabled page method which then called session.abandon. This triggers session end event and clears the session variable but unfortunately does not kill the session cookie!! as a result if other browser instances are open there are problems because their session state just disappeared...and much worse than this when I open the site again with the zombie session still not expired, I get multiple session start and session end events on any subsequent postbacks. This happens on all browsers. so how do I truly kill the session (force the cookie to expire)

  • ASP.NET MVC does not add ModelError when invoking from unit test

    - by Tomas Lycken
    I have a model item public class EntryInputModel { ... [Required(ErrorMessage = "Description is required.", AllowEmptyStrings = false)] public virtual string Description { get; set; } } and a controller action public ActionResult Add([Bind(Exclude = "Id")] EntryInputModel newEntry) { if (ModelState.IsValid) { var entry = Mapper.Map<EntryInputModel, Entry>(newEntry); repository.Add(entry); unitOfWork.SaveChanges(); return RedirectToAction("Details", new { id = entry.Id }); } return RedirectToAction("Create"); } When I create an EntryInputModel in a unit test, set the Description property to null and pass it to the action method, I still get ModelState.IsValid == true, even though I have debugged and verified that newEntry.Description == null. Why doesn't this work?

  • Separate functionality depending on Role in ASP.NET MVC

    - by Andrew Bullock
    I'm looking for an elegant pattern to solve this problem: I have several user roles in my system, and for many of my controller actions, I need to deal with slightly different data. For example, take /Users/Edit/1 This allows a Moderator to edit a users email address, but Administrators to edit a user's email address and password. I'd like a design for separating the two different bits of action code for the GET and the POST. Solutions I've come up with so far are: Switch inside each method, however this doesn't really help when i want different model arguments on the POST :( Custom controller factory which chooses a UsersController_ForModerators and UsersController_ForAdmins instead of just UsersController from the controller name and current user role Custom action invoker which choose the Edit_ForModerators method in a similar way to above Have an IUsersController and register a different implementation of it in my IoC container as a named instance based on Role Build an implementation of the controller at runtime using Castle DynamicProxy and manipulate the methods to those from role-based implementations Im preferring the named IoC instance route atm as it means all my urls/routing will work seamlessly. Ideas? Suggestions?

  • ASP.NET HTTPHandler not throwing exception when one is expected

    - by josephj1989
    I have an HttpHandler class (implements IHttphandler) where the path defined for the handler in web.config is *.jpg. I am requesting a Jpg image in my page. Within the HTTP Handler I am writing to a file in the filesystem. By mistake I was trying to write to a non existant directory. This should have thrown an exception but the execution simply proceeds.Ofcourse no file is written. But if I give a proper directory the file is written correctly.Is there anything special about HttpHandler Exceptions. See part of the code public void ProcessRequest(HttpContext context){ File.WriteAllLines(context.Request.ApplicationPath+@"\"+"resul.log",new string[]{"Entered JPG Handler"}); If I put a breakpoint on the File.WriteAllLines statement and then step over it I can see an exception occurring.

  • Linking jQuery UI to the ASP.NET MVC 2 project

    - by Tx3
    What I am trying to accomplish is using jQuery UI dialog method from my own JavaScript source code file. I have this kind of links in the Site.Master <script src="/Scripts/jquery-1.4.2.js" type="text/javascript"></script> <script src="/Scripts/jquery.validate.js" type="text/javascript"></script> <script src="/Scripts/jquery-ui.js" type="text/javascript"></script> <script src="/Scripts/Common.js" type="text/javascript"></script> Common.js is my own helper file. jQuery works fine there, but when I try to call for example: $(document).ready(function() { $("#dialog").dialog(); }); I'll get "Microsoft JScript runtime error: Object doesn't support this property or method" Any ideas why this happens? jQuery Works fine, but jQuery UI doesn't.

  • jQuery ajax post failing in asp

    - by Dave Kiss
    hey guys, this might be really stupid, but hopefully someone can help. I'm trying to post to an external script using ajax so i can mail the data, but for some reason my data is not making it to the script. $(document).ready(function() { $("#submitContactForm").click(function () { $('#loading').append('<img src="http://www.xxxxxxxx.com/demo/copyshop/images/loading.gif" alt="Currently Loading" id="loadingComment" />'); var name = $('#name').val(); var email = $('#email').val(); var comment = $('#comment').val(); var dataString = 'name='+ name + '&email=' + email + '&comment=' + comment; $.ajax({ url: 'http://www.xxxxx.com/demo/copyshop/php/sendmail.php', type: 'POST', data: '?name=Dave&[email protected]&comment=hiiii', success: function(result) { $('#loading').append('success'); } }); return false; }); }); the php script is simple (for now - just wanted to make sure it worked) <?php $name = $_POST['name']; $email = $_POST['email']; $comment = $_POST['comment']; $to = '[email protected]'; $subject = 'New Contact Inquiry'; $message = $comment; mail($to, $subject, $message); ?> the jquery is embedded in an .aspx page (a language i'm not familiar with) but is posting to a php script. i'm receiving emails properly but there is no data inside. am i missing something? i tried to bypass the variables in this example, but its still not working thanks

  • ASP.NET MVC download image rather than display in browser

    - by RSolberg
    Rather than displaying a PNG in the browser window, I'd like the action result to trigger the file download dialogue box (you know the open, save as, etc). I can get this to work with the code below using an unknown content type, but the user then has to type in .png at the end of the file name. How can I accomplish this behavior without forcing the user to type in the file extension? public ActionResult DownloadAdTemplate(string pathCode) { var imgPath = Server.MapPath(service.GetTemplatePath(pathCode)); return base.File(imgPath, "application/unknown"); }
