  • ASP.NET MVC pass information from controller to view WITHOUT ViewData, ViewModel, or Session

    - by josh
    I have a unique scenario where I want a base controller to grab some data and store it in a list. The list should be accessible from my views just as ViewData is. I will be using this list on every page and would like a cleaner solution than just shoving it in the ViewDataDictionary. After attempting to come up with a solution, I thought I would create a custom ViewPage with a property to hold my list. My custom ViewPage would inherit from System.Web.MVC.ViewPage. However, I do not know where MVC passes the viewdata from the controller off to the view. More importantly, how do I get it to pass my list down to the view? Thanks for the help.

  • Splitting a string in ASP Classic

    - by Sam
    So here's my string: Lorem ipsum dolor sit amet, consectetur adipiscing elit. Nullam elit lacus, dignissim quis laoreet non, cursus id eros. Etiam lacinia tortor vel purus eleifend accumsan. Pellentesque habitant morbi tristique senectus et netus et malesuada fames ac turpis egestas. Quisque bibendum vestibulum nisl vitae volutpat. I need to split it every 100 characters (full words only) until all the characters are used up. So we'd end up with: Lorem ipsum dolor sit amet, consectetur adipiscing elit. Nullam elit lacus, dignissim quis laoreet non, and cursus id eros. Etiam lacinia tortor vel purus eleifend accumsan. Pellentesque habitant morbi tristique and senectus et netus et malesuada fames ac turpis egestas. Quisque bibendum vestibulum nisl vitae volutpat. Any ideas on the best way to do that?

  • Setting the ASP.NET version via MSBUILD

    - by dovholuk
    I am trying to create a new website on a remote server via msbuild (I like to call it "msdeploy"). I've downloaded and used the SDC tasks, the MSBuildExtension tasks and the MSBuildCommunity tasks but I simply can't get it right. I figure that WebDirectorySetting (from MSBuild.Community.Tasks.IIS) is my best bet but I can't find the right SettingName to pass. I'd like to use some sort of MSBuild task to accomplish this but maybe it just doesn't exist. Custom VBS or WMI are my last resort... Thanks

  • .net user control event handler lost on postback

    - by user154008
    I have a menu usercontrol called LeftMenu that has a bulletedlist of linkitems. It's on the ascx page as such: <asp:BulletedList ID="PublisherList" DisplayMode="LinkButton" OnClick="PublisherList_Click" cssClass="Menu" runat="server"></asp:BulletedList> I databind the list in the page_load under if(!isPostBack) I'm having an issue on a page that loads the control. When the page first loads, the event handler fires. However, when the page posts back it no longer fires and in IE8, when I'm debugging, I get "Microsoft JScript runtime error: Object expected" in Visual Studio pointing at "doPostBack('LeftMenu$PublisherList','0')." In FF I don't get the error, but nothing happens. I'm **not loading the control dynamically, it's loaded on the aspx page using: <%@ Register TagPrefix="Standards" TagName="LeftMenu" Src="LeftMenu.ascx" %> <Standards:LeftMenu ID="LeftMenu" runat="server"/> Any ideas of where I'm losing the event handler? I just realized this is happening on another user control I have as well. A text box and a button and I'm using the default button to make sure pressing the enter key uses that button. .Net converts that in the html to: <div id="SearchBarInclude_SearchBar" onkeypress="javascript:return WebForm_FireDefaultButton(event, 'SearchBarInclude_QuickSearchButton')"> so as soon as i enter a key in the box I get a javascript error at the line saying "object expected." It seems like the two issues are related. Edit Again: I think I need to clarify. It's not that I'm clicking on the menu item and it can't find the selected item on postback. I have this search page with the left navigation on it and then the main content of the page is something that causes a postback. Everything is fine with this postback. Once that page has been posted back, now if I click on the bulleted list in the left navigation I get a javascript error and it fails. The page_init for the LeftMenu control is never called.

  • ASP.NET - fast Segmented downoad of file through webservice

    - by H4mm3rHead
    Hi, Im doing this project where i need to download files through a webservice (images, videos). The download MUST go through an existing webservice. The existing webservice was made when there were no need to upload and download files but the project has changed and now we need to do It through a webservice. Right now I have implemented the download as a method that returns a byte[], I open a streamreader and resds the entire file into a byte[] and returns it to my method. This is working file on small files <~1Mb, above it takes too long time. I want to show some progress (e.g. when the user downlaods a 20Mb video) which i cannot do right now. And i want to make it download much faster (is a strategy to use multithreading and several threads that downloads a part of the file?). It is within a WPF application i need to do this. Any ideas on how to approach this?

  • Generic data input form in asp.net mvc application

    - by Diego
    Hello, I have an application that have EF 16 classes that share this information: They all are classes only with a key field and a description. I think it should be a waste if I make a controller with just 1 method just to present a form to fill these classes info, then I was thinking in to make a generic form(with key, description) and dynamically fill the right class through a sort of selection the selected info in any way, any good suggestion or pattern to do that? Where the generic methods should be located.

  • Providing SaaS functionality to a .NET portal with DLLs

    - by Abdullah Jibaly
    I'm not sure I'm asking the right question here, but I'm looking to provide web based functionality from one ASP.NET application to another remote 'portal-like' application. Is it possible to simply give the portal a DLL? As an example, let's say the SaaS web app has a patient-entry form that I want to be able to use from the portal application. I would like the portal app to be able to set preferences (permissions, color, style, etc), make a function call, and have that capability presented within a certain div or something. Is there any .NET technologies that provide this kind of integration?

  • NHibernate session management in ASP.NET MVC

    - by Kevin Pang
    I am currently playing around with the HybridSessionBuilder class found on Jeffrey Palermo's blog post: http://jeffreypalermo.com/blog/use-this-nhibernate-wrapper-to-keep-your-repository-classes-simple/ Using this class, my repository looks like this: public class UserRepository : IUserRepository { private readonly ISessionBuilder _sessionBuilder; public UserRepository(ISessionBuilder sessionBuilder) { _sessionBuilder = sessionBuilder; } public User GetByID(string userID) { using (ISession session = _sessionBuilder.GetSession()) { return session.Get<User>(userID); } } } Is this the best way to go about managing the NHibernate session / factory? I've heard things about Unit of Work and creating a session per web request and flushing it at the end. From what I can tell, my current implementation isn't doing any of this. It is basically relying on the Repository to grab the session from the session factory and use it to run the queries. Are there any pitfalls to doing database access this way?

  • ASP.Net MVC Outbound Route Matching Problem When Using ActionLink

    - by Godders
    Hi there, Hoping for some help after reading into MVC routing and not coming up with the answer myself. I have the following routes registered: public static void RegisterRoutes(RouteCollection routes) { routes.IgnoreRoute("{resource}.axd/{*pathInfo}"); routes.MapRoute( null, "YourFeedback/Article/{resourceId}", new { controller = "YourFeedback", action = "Index", contentTypeId = new Guid(ConfigurationManager.AppSettings["ArticleLibraryId"]) }); routes.MapRoute( "Default", // Route name "{controller}/{action}/{id}", // URL with parameters new { controller = "Home", action = "Index", id = "" } // Parameter defaults ); } I have the following ActionLink in an aspx view: <%=Html.ActionLink("Your Feedback", "Article", "YourFeedback", new { resourceId = Model.ContentId.ResourceId }, new { @class = "yourFeedback" })%> My understanding of MVC routing is that this would render a anchor link with href of "/YourFeedback/Article/101" where 101 comes from Model.ContentId.ResourceId. Yet the anchor link href is rendered as "YourFeedback/Article/resourceId=101". Any ideas where I'm going wrong? Thanks in advance.

  • Hide Non-Displayed ASP Elements in Design View

    - by Steven
    Is there a way to prevent non-displayed elements from appearing in the ASPX Design View editor? By "non-displayed elements", I mean the background elements (Managers, DataSources, Validators, etc) that show up as grey boxes containing the type and id. If I have several of those at the top of the page, I can't see much of the preview of my page.

  • How do I 'donut cache' in ASP.NET MVC for something more than a date

    - by Simon_Weaver
    All the examples for donut caching I've seen are just like this : <%= Html.Substitute( c => DateTime.Now.ToString() )%> Thats fine if I just want the date, but what other options are there? I know there is a delegate 'MvcSubstitutionCallback' which has the following signature : public delegate string MvcSubstitutionCallback(HttpContextBase httpContext); but RenderAction and RenderPartial returns void so i cant just return them from the delegate method. How can I effectively use this callback for more complex situations. I've looked at both of Phil Haacked's articles here and here, but neither seems to do exactly what I want.

  • Force lowercase property names from Json() in ASP.NET MVC

    - by kouPhax
    Given the following class, public class Result { public bool Success { get; set; } public string Message { get; set; } } I am returning one of these in a Controller action like so, return Json(new Result() { Success = true, Message = "test"}) However my client side framework expects these properties to be lowercase success and message. Without actually having to have lowercase property names is that a way to acheive this thought the normal Json function call?

  • ASP.NET: Turning on errors

    - by JamesBrownIsDead
    This is what I see when I visit my web site. How do I instead get the Yellow Screen of Death so I know what the error is? I have GoDaddy shared hosting and I think the problem is that I don't have the correct MVC binaries in the /bin folder. My web.config shows this: <add assembly="System.Web.Mvc, Version=2.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/> <add assembly="System.Web.Abstractions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/> <add assembly="System.Web.Routing, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/> But I'm not positive I copied the right .DLL files into /bin. I've got like 8 of each file--which version is which?!

  • ASP .net MVC Jqgrid data binding

    - by SARAVAN
    Hi, I am using a jqgrid with a column named 'Comments'. My controller code returns data as follows: var jsonData = new { rows= .... .... select new { col1.... col2.... Comments = _Model.GetComments(id), }) ....... ..... return Json(jsonData, JsonRequestBehavior.AllowGet); } _Model.GetComments(id) will return a ClientComments Object which has a few properties say CommentID, FirstName, MiddleName etc., which will be bound to each row in the grid Now in my jqgrid I need to build a tool tip based on Comments column properties and for that I need to use the properties of my Comments in JQGrid for each row. May I know How I can manipulate Comment's properties for each row? Any help would be appreciated. I tried in my javascript that for each row rowObject.Comments.FirstName and it did not work.

  • C# ASP.NET Binding Controls via Generic Method

    - by OverTech
    I have a few web applications that I maintain and I find myself very often writing the same block of code over and over again to bind a GridView to a data source. I'm trying to create a Generic method to handle data binding but I'm having trouble getting it to work with Repeaters and DataLists. Here is the Generic method I have so far: public void BindControl<T>(T control, SqlCommand sql) where T : System.Web.UI.WebControls.BaseDataBoundControl { cmd = sql; cn.Open(); SqlDataReader dr = cmd.ExecuteReader(); if (dr.HasRows) { control.DataSource = dr; control.DataBind(); } dr.Close(); cn.Close(); } That way I can just define my CommandText then make a call to "BindControls(myGridView, cmd)" instead of retyping this same basic block of code every time I need to bind a grid. The problem is, this doesn't work with Repeaters or DataLists. Each of these controls inherit their respective "DataSource" and "DataBind" methods from different classes. Someone on another forum suggested that I implement an interface, but I'm not sure how to make that work either. The GridView, Datalist and Repeater get their respective "DataBind" methods from BaseDataBoundControl, BaseDataList, and Repeater classes. How would I go about creating a single interface to tie them all together? Or am I better off just using 3 overloads for this method? Dave

  • 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.net-mvc feature - one css file per (view / master-page / user-control)

    - by Mendy
    I'm trying to implement the following feature: I want just one css file to be attached for any page that I rendered. For example take StackOverflow site. For the questions page, we will have questions.css file. so.com/questions ---> questions.css so.com/question/1234/title ---> question.css so.com/about ---> about.css so.com/faq ---> faq.css Now, I know that this css files share code in common, because they may have the same MasterPage(s) / UserControls. So, the solution need to take into account MasterPages, views and usercontrols as well. So, what will be the right solution for this kind of problem? I'm thinking about one solution, I'll put is as an answer, but maybe you have a better solution for this?
