  • ASP.NET catching controls from html generated from the database

    - by Drahcir
    I have a set of websites that basically do the exact same thing in terms of functionality, the only thing that varies is the css and how the html is laid out. Is there a way to generate the html from a database (ie retreiving the html from a table) and then catching the controls (like buttons, textboxes etc) from the code behind? UPDATE: Here is an example of what I want to acheive: <html> <div id="generatedContent" runat="server"> <!-- the following content has been generated from the database on the page load event --> <div> This is a textbox <input id="tb1" runat="server" type="text" /> This is a button <input type="submit" id="btn1" runat="server" value="My Button" /> </div> </div> </html> This is the code behind var tb1 = new HtmlControls.HtmlInputText(); tb1 = FindControl("tb1"); var btn1 = new New HtmlControls.HtmlInputSubmit(); btn1 = FindControl("btn1"); Now obviously since the html has been generated from the database (ie after the page has already been initialised) the FindControl method will return null.

  • Asp.net mvc small amount data storage

    - by Trimack
    Hi there, I am writing some learning tests (i.e. what's the answer for...; choose correct options...). Now my question is, how should I store them. SQL db seems quite an overkill, but I really don't know what would be the best choice if I wanted to select random subset of questions etc. Perhaps some simple xml files? Thanks for advice.

  • how to pass an id number string to this class (asp.net, c#)

  • Login time out when calling opening a new window from modal popup (ASP.NET)

    - by Harsh Shah
    I have a weird problem. I have a window, on a button click I open a modal popup (using ModelPopupExtender), that let's you select a few criteria and then click a submit button. On click of submit button, I open a new window (using window.open()) that shows the status of what happened to your submitted request. However, every time this status window is opened, it goes to the login page. I am thinking the modal popup can't pass the authentication cookie to the newly opened window, but I'm not sure. Here's my web.config portion:

    here is my view code: <%=Model.HtmlData %> here is my controller code: public ActionResult GetPage() { ContentPageViewModel vm = new ContentPageViewModel(); vm.HtmlData = _htmlPageRepository.Get("key"); return View(vm); } my repository class basically queries a database table that has the fields: id, pageName, htmlContent the .Get() method passes in a pageName (or key) and returns the htmlContent value.

  • Asp Dot Net : IHttpModule + m_context.Server.Transfer = session state error

    - by tinky05
    I have an IHttpModule that implements IRequiresSessionState. The session state is at "on" on the page directive and I also added it to the web.config. In the method "OnBeginRequest" in the IHttpModule, I make a Server.Transfer but I get the error : Session state can only be used when enableSessionState is set to true, either in a configuration file or in the Page directive. When I access the page directly or with a Response.Redirect, there is no error. Any idea?

  • ASP MVC Populate drop down list on jQuery add table row

    - by Jacob Huggart
    I have a page with several drop down lists that all have the same contents. The page starts out with only three ddls, but more need to be added based on user input. There is also other information associated with the drop down lists that is all in a table. So, when the user clicks a link I add a new row of textboxes and drop down lists to a table. When I add a row to my table, the new drop down lists are empty because there is no view data associated with them. How can I use ajax or jquery to pull the viewdata that I need to populate new drop down lists?

  • Setting current culture with threads in ASP.NET MVC

    - by mare
    Here's an example of SetCulture attribute which inside does something like this: public void OnActionExecuting(ActionExecutingContext filterContext) { string cultureCode = SetCurrentLanguage(filterContext); if (string.IsNullOrEmpty(cultureCode)) return; HttpContext.Current.Response.Cookies.Add( new HttpCookie("Culture", cultureCode) { HttpOnly = true, Expires = DateTime.Now.AddYears(100) } ); filterContext.HttpContext.Session["Culture"] = cultureCode; CultureInfo culture = new CultureInfo(cultureCode); System.Threading.Thread.CurrentThread.CurrentCulture = culture; System.Threading.Thread.CurrentThread.CurrentUICulture = culture; } I was wondering how does this affect a site with multiple users logged on and each one setting their own culture? What is the scope of a thread here with regards to the IIS worker process (w3wp) that the site is running in?

  • jquery-ui autocomplete with ASP MVC suggestions not displaying

    - by adamnickerson
    I have been trying to get a simple example of the jquery-ui autocomplete to work. I have a controller setup to handle the query, and it returns the json that looks to be in order, but I am getting no suggestions showing up. Here are the js libraries I am including: <script type="text/javascript" language="javascript" src="/Scripts/jquery-1.4.1.js"></script> <script type="text/javascript" language="javascript" src="/Scripts/jquery-ui-1.8.1.custom.min.js"></script> <link href="/Content/jquery-ui-1.8.1.custom.css" rel="stylesheet" type="text/css" /> and here is the javascript and the form tags: <script type="text/javascript"> $(function () { $("#organization").autocomplete({ source: function (request, response) { $.ajax({ url: '/Organization/OrganizationLookup', dataType: "json", data: { limit: 12, q: request.term } }) }, minLength: 2 }); }); </script> <div class="ui-widget"> <label for="organization">Organization: </label> <input id="organization" /> </div> I get back a json response that looks reasonable from my controller: [{"id":"Sector A","value":"Sector A"},{"id":"Sector B","value":"Sector B"},{"id":"Sector C","value":"Sector C"}] id and value seem to be the default naming that autocomplete is looking for. But I get no joy at all. Any thoughts?

  • asp.net mvc How to test controllers correctly

    - by Simon G
    Hi, I'm having difficulty testing controllers. Original my controller for testing looked something like this: SomethingController CreateSomethingController() { var somethingData = FakeSomethingData.CreateFakeData(); var fakeRepository = FakeRepository.Create(); var controller = new SomethingController(fakeRepository); return controller; } This works fine for the majority of testing until I got the Request.IsAjaxRequest() part of code. So then I had to mock up the HttpContext and HttpRequestBase. So my code then changed to look like: public class FakeHttpContext : HttpContextBase { bool _isAjaxRequest; public FakeHttpContext( bool isAjaxRequest = false ) { _isAjaxRequest = isAjaxRequest; } public override HttpRequestBase Request { get { string ajaxRequestHeader = ""; if ( _isAjaxRequest ) ajaxRequestHeader = "XMLHttpRequest"; var request = new Mock<HttpRequestBase>(); request.SetupGet( x => x.Headers ).Returns( new WebHeaderCollection { {"X-Requested-With", ajaxRequestHeader} } ); request.SetupGet( x => x["X-Requested-With"] ).Returns( ajaxRequestHeader ); return request.Object; } } private IPrincipal _user; public override IPrincipal User { get { if ( _user == null ) { _user = new FakePrincipal(); } return _user; } set { _user = value; } } } SomethingController CreateSomethingController() { var somethingData = FakeSomethingData.CreateFakeData(); var fakeRepository = FakeRepository.Create(); var controller = new SomethingController(fakeRepository); ControllerContext controllerContext = new ControllerContext( new FakeHttpContext( isAjaxRequest ), new RouteData(), controller ); controller.ControllerContext = controllerContext; return controller; } Now its got to that stage in my controller where I call Url.Route and Url is null. So it looks like I need to start mocking up routes for my controller. I seem to be spending more time googling on how to fake/mock objects and then debugging to make sure my fakes are correct than actual writing the test code. Is there an easier way in to test a controller? I've looked at the TestControllerBuilder from MvcContrib which helps with some of the issues but doesn't seem to do everything. Is there anything else available that will do the job and will let me concentrate on writing the tests rather than writing mocks? Thanks

  • Can't send smtp email from network using C#, asp.net website

    - by Kaysar
    Hi, I have my code here, it works fine from my home, where my user is administrator, and I am connected to internet via a cable network. But, problem is when I try this code from my work place, it does not work. Shows error: "unable to connect to the remote server" From a different machine in the same network: "A socket operation was attempted to an unreachable network 209.xxx.xx.52:25" I checked with our network admin, and he assured me that all the mail ports are open [25,110, and other ports for gmail]. Then, I logged in with administrative privilege, there was a little improvement, it did not show any error, but the actual email was never received. Please note that, the code was tested from development environment, visual studio 2005 and 2008. Any suggestion will be much appreciated. Thanks in advance try { MailMessage mail_message = new MailMessage("[email protected]", txtToEmail.Text, txtSubject.Text, txtBody.Text); SmtpClient mail_client = new SmtpClient("SMTP.y7mail.com"); NetworkCredential Authentic = new NetworkCredential("[email protected]", "xxxxx"); mail_client.UseDefaultCredentials = true; mail_client.Credentials = Authentic; mail_message.IsBodyHtml = true; mail_message.Priority = MailPriority.High; try { mail_client.Send(mail_message); lblStatus.Text = "Mail Sent Successfully"; } catch (Exception ex) { System.Diagnostics.Debug.WriteLine(ex.Message); lblStatus.Text = "Mail Sending Failed\r\n" + ex.Message; } } catch (Exception ex) { lblStatus.Text = "Mail Sending Failed\r\n" + ex.Message; }
