  • asp.net mvc 1.0 - how to render a partial view as a string

    - by Chev
    Hi There I need to render a partial view to a string within a controller action. I have the following sample code, but the ControllerContext.ParentActionViewContext does not seem to exist in mvc 1.0 // Get the IView of the PartialView object. var view = PartialView("MyPartialView").View; // Initialize a StringWriter for rendering the output. var writer = new StringWriter(); // Do the actual rendering. view.Render(ControllerContext.ParentActionViewContext, writer); Any tips greatly appreciated.

  • ASP.NET - Overriding Gridview OnRowCreated to add sort images -- columns are null

    - by Zach
    I'm overriding the onrowcreated to add sort images to the header row of a gridview. This works, but actually adding a sortexpression doesn't. What I want to do is set the images as imagebuttons and set their commandarguments to the sort expression of the column they are sorting for. I would assume I could get the cell and from it's index get the gridviewcolumn. Then, I could just get the sortexpression of the gridview column, but this does not work. The columns are null. OnRowCreated Code snippet below: //if this is the header row, we add sort images to each cell if (row.RowType == DataControlRowType.Header) { //iterate through the cells for (int i = 0; i < row.Cells.Count; i++) { //if the column is sortable and visible if (this.Columns[i].SortExpression != string.Empty && this.Columns[i].Visible) { string strSort = this.Columns[i].SortExpression; } } } Can we not get columns in OnRowCreated like this?

  • Dependency Injection Question - ASP.NET

    - by Paul
    I'm starting a web application that contains the following projects: Booking.Web Booking.Services Booking.DataObjects Booking.Data I'm using the repository pattern in my data project only. All services will be the same, no matter what happens. However, if a customer wants to use Access, it will use a different data repository than if the customer wants to use SQL Server. I have StructureMap, and want to be able to do the following: Web project is unaffected. It's a web forms application that will only know about the services project and the dataobjects project. When a service is called, it will use StructureMap (by looking up the bootstrapper.cs file) to see which data repository to use. An example of a services class is the error logging class: public class ErrorLog : IErrorLog { ILogging logger; public ErrorLog() { } public ErrorLog(ILogging logger) { this.logger = logger; } public void AddToLog(string errorMessage) { try { AddToDatabaseLog(errorMessage); } catch (Exception ex) { AddToFileLog(ex.Message); } finally { AddToFileLog(errorMessage); } } private void AddToDatabaseLog(string errorMessage) { ErrorObject error = new ErrorObject { ErrorDateTime = DateTime.Now, ErrorMessage = errorMessage }; logger.Insert(error); } private void AddToFileLog(string errorMessage) { // TODO: Take this value from the web.config instead of hard coding it TextWriter writer = new StreamWriter(@"E:\Work\Booking\Booking\Booking.Web\Logs\ErrorLog.txt", true); writer.WriteLine(DateTime.Now.ToString() + " ---------- " + errorMessage); writer.Close(); } } I want to be able to call this service from my web project, without defining which repository to use for the data access. My boostrapper.cs file in the services project is defined as: public class Bootstrapper { public static void ConfigureStructureMap() { ObjectFactory.Initialize(x => { x.AddRegistry(new ServiceRegistry()); } ); } public class ServiceRegistry : Registry { protected override void configure() { ForRequestedType<IErrorLog>().TheDefaultIsConcreteType<Booking.Services.Logging.ErrorLog>(); ForRequestedType<ILogging>().TheDefaultIsConcreteType<SqlServerLoggingProvider>(); } } } What else do I need to get this to work? When I defined a test, the ILogger object was null. Thanks,

  • DataAnnotations in ASP.NET MVC 2 - Stop MVC from applying RequiredAttribute to Non-nullable DateTime

    - by jwwishart
    Im trying to create a custom version of the RequiredAttribute to replace the built in one and I've got it working for properties that have strings values, but with properties that are DateTime or integer for example, the default RequiredAttribute seems to be applied automatically (IF the property is not nullable!) My problem is that i want to be able to specify a DateTime property as required using my custom required validator which gets the error message from a resources file (I don't want to have to tell the RequiredAttribute the type of the resource file and the key every time i apply it. That is why I'm making a custom one.) How can i prevent the framework from applying the required attribute to properties of type DateTime and int etc without changing them to nullable. Thanks

  • ASP.NET custom routes for simple requirements management tool

    - by Andrew
    I am implementing a very simple requirements management tool. I want the URLs to look like this: Shows home page for "Project One": http://projectmanager/Project/Project%20One Shows a list of requirements being worked on for "Project One" http://projectmanager/Project/Project%20One/Requirements Shows requirement 1 for "Project One" http://projectmanager/Project/Project%20One/Requirement/1 How could I set up routes so that http://projectmanager/Project/Project%20One is handled by the project controller http://projectmanager/Project/Project%20One/Requirements and http://projectmanager/Project/Project%20One/Requirements/1 is handled by the requirements controller. Is it even possible?

  • Switching AM/PM in ASP.NET AJAX MaskedEdit localization

    - by Greg
    The sample page for the MaskedEdit says "Tip: Type 'A' or 'P' to switch AM/PM". Are these keys hardcoded? Does the control automatically change itself for cultures that use 12-hour designators that don't start with A or P? Or is just broken for those? example: Arabic (Saudi Arabia) - AM: ? Arabic (Saudi Arabia) - PM: ? Chinese (Taiwan) - AM: ?? Chinese (Taiwan) - PM: ?? Greek (Greece) - AM: pµ Greek (Greece) - PM: µµ Korean (Korea) - AM: ?? Korean (Korea) - PM: ?? Albanian (Albania) - AM: PD Albanian (Albania) - PM: MD Persian (Iran) - AM: ?.? Persian (Iran) - PM: ?.? Vietnamese (Vietnam) - AM: SA Vietnamese (Vietnam) - PM: CH Afrikaans (South Africa) - PM: nm Punjabi (India) - AM: ????? Punjabi (India) - PM: ??? Syriac (Syria) - AM: ?.? Syriac (Syria) - PM: ?.? If this control doesn't handle this situation, does anyone know of a control that does?

  • ASP.NET - Display Message While Page Is Loading

    - by Chris
    I have a page that performs a long-running task (10 to 15 seconds) in the page_load method. I have client-side javascript code that will display a decent "page loading" animated gif to the user. I am able to invoke the JavaScript method from the code-behind, to display the "page loading" animated gif, however, the long-running task is hanging up the UI such that the animated gif doesn't actually display until after the long-running task is complete, which is the exact opposite of what I want. To test this out, in my page_load method I make a call to the JavaScript method to display the animated gif. Then, I use Thread.Sleep(10000). What happens is that the animated gif doesn't display until after Thread.Sleep is complete. Obviously I am doing something incorrect. Any advice would be appreciated. Thanks. Chris

  • Updating a DLL in a Production ASP.NET Web Site bin folder

    - by Josh Stodola
    I want to update a class library (a single DLL file) in a production web application. This web app is pre-compiled (published). I read an answer on StackOverflow (sorry, can't seem to find it anymore because the Search function does not work very well), that led me to believe that I could just paste the new DLL in the bin folder and it would be picked up without problems (this would cause the WP to recycle, which is fine with me because we do not use InProc session state). However, when I tried this, my site blows up and gives a FileLoadException saying that the assembly manifest definition does not match the assembly reference. What in the world is this?! Updating the DLL in Visual Studio and re-deploying the entire site works just fine, but it is a huge pain in the rear. What is the point of having a separate DLL if you have to re-deploy the entire site to implement any changes? Here's the question: How can I update a DLL on a production web site without breaking the app and without re-deploying all of the files?

  • Alternative to COM blind aggregation in .NET for class with private interface

    - by Philip
    When extending a COM class in unmanaged C++ where the original class has private interfaces, one way to do this is through the concept of blind aggregation. The idea is that any interface not explicitly implemented on the outer aggregating class is 'blindly' forwarded to the inner aggregated class. Now .NET as far as I can figure out does not support COM aggregation natively. A somewhat tedious workaround is to create a .NET class where you implement all the required COM interfaces directly on the .NET class and simply forward to an instance of the actual COM class for any methods you don't want to override. The problem I have is when the original COM object has one or more private interfaces, i.e. undocumented interfaces that are nonetheless used by some consumers of the original class. Using blind aggregation in unmanaged C++ this is a non-issue as the calls to the private interfaces are automatically forwarded to the original class, however I can't find any way of doing the same thing in .NET. Are there any other ways of accomplishing this with .NET?

  • .net open auth?

    Hi I know stackoverflow uses open authentication. I want to try and use this as well. I am using asp.net mvc 2.0 with C#. I found this http://www.dotnetopenauth.net/ and I am wondering if this is what was used for stackoverflow. Also any tutorials would be nice as well.

  • Custom DateTime model binder in Asp.net MVC

    - by Robert Koritnik
    I would like to write my own model binder for DateTime type. First of all I'd like to write a new attribute that I can attach to my model property like: [DateTimeFormat("d.M.yyyy")] public DateTime Birth { get; set,} This is the easy part. But the binder part is a bit more difficult. I would like to add a new model binder for type DateTime. I can either implement IModelBinder interface and write my own BindModel() method inherit from DefaultModelBinder and override BindModel() method My model has a property as seen above (Birth). So when the model tries to bind request data to this property, my model binder's BindModel(controllerContext, bindingContext) gets invoked. Everything ok, but. How do I get property attributes from controller/bindingContext, to parse my date correctly? How can I get to the PropertyDesciptor of property Birth? Edit Because of separation of concerns my model class is defined in an assembly that doesn't (and shouldn't) reference System.Web.MVC assembly. Setting custom binding (similar to Scott Hanselman's example) attributes is a no-go here.

  • Generate links for routes with non-parameter url segments on ASP.NET MVC 2

    - by spapaseit
    I have a route defined with several hardcoded (non-parameter) segments: routes.MapRoute(null, "suggestion/list/by/{tag}", new { controller = "Suggestion", action = "List", tag = UrlParameter.Optional }); Suppose I'm in the Index view of SuggestionController, which has a Suggestion object for Model, how can I create a link that matches that route? I'd rather use one of the provided helpers and keep the route name as null in order to avoid hard-coding to much on my views, but I can't figure out how to user these non-parameter segments in Html.ActionLink or RouteLink methods. I've even tried to render the link using plain ol' html <a href="/suggestion/list/by/<%=Model.Tag %>"><%=Model.Tag %></a> but this somehow didn't match the route either. There's probably a very simple solution and I might be over-complicating things in mi mind, but I'm at a loss. Any ideas? Thanks in advance.
