  • UpdateModel() fails after migration from MVC 1.0 to MVC 2.0

    - by Alastair Pitts
    We are in the process of migrating our ASP.NET MVC 1.0 web app to MVC 2.0 but we have run into a small snag. In our report creation wizard, it is possible leave the Title text box empty and have it be populated with a generic title (in the post action). The code that does the update on the model of the Title is: if (TryUpdateModel(reportToEdit, new[] { "Title" })) { //all ok here try to create (custom validation and attach to graph to follow) //if title is empty get config subject if (reportToEdit.Title.Trim().Length <= 0) reportToEdit.Title = reportConfiguration.Subject; if (!_service.CreateReport(1, reportToEdit, SelectedUser.ID, reportConfigID, reportCategoryID, reportTypeID, deviceUnitID)) return RedirectToAction("Index"); } In MVC 1.0, this works correctly,the reportToEdit has an empty title if the textbox is empty, which is then populated with the Subject property. In MVC 2.0 this fails/returns false. If I add the line above: UpdateModel(reportToEdit, new[] { "Title" }); it throws System.InvalidOperationException was unhandled by user code Message="The model of type 'Footprint.Web.Models.Reports' could not be updated." Source="System.Web.Mvc" StackTrace: at System.Web.Mvc.Controller.UpdateModel[TModel](TModel model, String prefix, String[] includeProperties, String[] excludeProperties, IValueProvider valueProvider) at System.Web.Mvc.Controller.UpdateModel[TModel](TModel model, String[] includeProperties) at Footprint.Web.Controllers.ReportsController.Step1(FormCollection form) in C:\TFS Workspace\ExtBusiness_Footprint\Branches\apitts_uioverhaul\Footprint\Footprint.Web\Controllers\ReportsController.cs:line 398 at lambda_method(ExecutionScope , ControllerBase , Object[] ) at System.Web.Mvc.ActionMethodDispatcher.Execute(ControllerBase controller, Object[] parameters) at System.Web.Mvc.ReflectedActionDescriptor.Execute(ControllerContext controllerContext, IDictionary`2 parameters) at System.Web.Mvc.ControllerActionInvoker.InvokeActionMethod(ControllerContext controllerContext, ActionDescriptor actionDescriptor, IDictionary`2 parameters) at System.Web.Mvc.ControllerActionInvoker.<>c__DisplayClassd.<InvokeActionMethodWithFilters>b__a() at System.Web.Mvc.ControllerActionInvoker.InvokeActionMethodFilter(IActionFilter filter, ActionExecutingContext preContext, Func`1 continuation) InnerException: Reading the MVC2 Release notes I see this breaking change: Every property for model objects that use IDataErrorInfo to perform validation is validated, regardless of whether a new value was set. In ASP.NET MVC 1.0, only properties that had new values set would be validated. In ASP.NET MVC 2, the Error property of IDataErrorInfo is called only if all the property validators were successful. but I'm confused how this is affecting me. I'm using the entity framework generated classes. Can anyone pinpoint why this is failing?

  • Conditional Regular Expression testing of a CSV

    - by Alastair Pitts
    I am doing some client side validation in ASP.NET MVC and I found myself trying to do conditional validation on a set of items (ie, if the checkbox is checked then validate and visa versa). This was problematic, to say the least. To get around this, I figured that I could "cheat" by having a hidden element that would contain all of the information for each set, thus the idea of a CSV string containing this information. I already use a custom [HiddenRequired] attribute to validate if the hidden input contains a value, with success, but I thought as I will need to validate each piece of data in the csv, that a regular expression would solve this. My regular expression work is extremely weak and after a good 2 hours I've almost given up. This is an example of the csv string: true,3,24,over,0.5 to explain: true denotes if I should validate the rest. I need to conditionally switch in the regex using this 3 and 24 are integers and will only ever fall in the range 0-24. over is a string and will either be over or under 0.5 is a decimal value, of unknown precision. In the validation, all values should be present and at least of the correct type Is there someone who can either provide such a regex or at least provide some hints, i'm really stuck!

  • SQL INSTR() using CSV. Need exact match rather than part

    - by Alastair Pitts
    This is a follow up issue relating to the answer for http://stackoverflow.com/questions/2445029/sql-placeholder-in-where-in-issue-inserted-strings-fail Quick background: We have a SQL query that uses a placeholder value to accept a string, which represents a unique tag/id. Usually, this is only a single tag, but we needed the ability to use a csv string for multiple tags, returning a combined result. In the answer we received from the vendor, they suggested the use of the INSTR function, ala: select * from pitotal where tag IN (SELECT tag from pipoint WHERE INSTR(?, tag) <> 0) and time between 'y' and 't' This works perfectly well 99% of the time, the issue is when the tag is also a subset of 2 parts of the CSV string. Eg the placeholder value is: 'northdom,southdom,eastdom,westdom' and possible tags include: north or northdom What happens, as north is a subset of northdom, is that the two tags are return instead of just northdom, which is actually what we want. I'm not strong on SQL so I couldn't work out how to set it as exact, or split the csv string, so help would be appreciated. Is there a way to split the csv string or make it look for an exact match?

  • Determining which form input failed validation?

    - by Alastair Pitts
    I am designing a creation wizard in ASP.NET MVC 1 and instead of posting back each step, I'm using javascript to toggle the display of the different steps divs. This is a quick sample of the code, just to explain. <% using (Html.BeginForm()) {%> <fieldset> <legend>Fields</legend> <div id="wizardStep1"> <% Html.RenderPartial("CreateStep1", Model); %> </div> <div id="wizardStep2"> <% Html.RenderPartial("CreateStep2", Model); %> </div> <div id="wizardStep3"> <% Html.RenderPartial("CreateStep3", Model); %> </div> </fieldset> <% } %> I have javascript that just toggles the visibility of the divs, with each partial view containing a different section of the input form (which is pretty large by itself) My question is, if the form fails validation and I reload the page with the validation errors, is there a way for me to determine which div contains the error? Either in javascript or other? Failing that, is there a good client-side validation library for MVC 1? Ideally I'd love to move to MVC2 and the client side validation built into that, but I am required to use MVC1

  • Updating a Foreign Key constraint with ON DELETE CASCADE not updating?

    - by Alastair Pitts
    We've realised in our SQL Server 2005 DB that some Foreign Keys don't have the On Delete Cascade property set, which is giving us a couple of referential errors when we try and delete some records. Use the Management Studio I scripted the DROP and CREATESQL's, but it seems that the CREATE isn't working correctly. The DROP: USE [FootprintReports] GO IF EXISTS (SELECT * FROM sys.foreign_keys WHERE object_id = OBJECT_ID(N'[dbo].[FK__SUBSCRIPTIONS_Reports]') AND parent_object_id = OBJECT_ID(N'[dbo].[_SUBSCRIPTIONS]')) ALTER TABLE [dbo].[_SUBSCRIPTIONS] DROP CONSTRAINT [FK__SUBSCRIPTIONS_Reports] and the CREATE USE [FootprintReports] GO ALTER TABLE [dbo].[_SUBSCRIPTIONS] WITH CHECK ADD CONSTRAINT [FK__SUBSCRIPTIONS_Reports] FOREIGN KEY([PARAMETER_ReportID]) REFERENCES [dbo].[Reports] ([ID]) ON DELETE CASCADE GO ALTER TABLE [dbo].[_SUBSCRIPTIONS] CHECK CONSTRAINT [FK__SUBSCRIPTIONS_Reports] If I manually change the value of the On Delete in the GUI, after dropping and recreating, the On Delete isn't correctly updated. As a test, I set the Delete rule in the GUI to Set Null. It dropped correctly, and recreated without error. If I got back into the GUI, it is still showing the Set Null as the Delete Rule. Have I done something wrong? or is there another way to edit a constraint to add the ON DELETE CASCADE rule?

  • multiple redirect??

    - by Ryan Pitts
    Ok, i won't go into the full details (too much to explain) but here is what i am trying to do. I have a button on a webpage (we'll call page-1) that links to a page (we'll call it page-2). This page opens in the same window. However, i need the page (page-2) that opens to open up a new window with another page (we'll call this one page-3) when it loads. So virtually when you click the initial button (on page-1) it will go to a new page (page-2) AND a window will open as well with a different page (page-3). This is where it gets tricky. I need page-2 to automatically redirect back to page-1 after it launches page-3. Is this possible and if so, how?? Could it be a JQuery thing? Please just give some answers...i know this is way crazy and a huge workaround - but this is my last resort for this particular website. I have to do it this way because of the lack of control over some of the code.

  • ASP.NET MVC: Problem generating thumbnails...need help!

    - by Ryan Pitts
    Ok, so i'm new to asp.net mvc and i'm trying to make a web application photo gallery. I've posted once on here about this issue i am having of trying to generate thumbnails on-the-fly on the page instead of the actual full-size images. Basically, the functionality i am looking for is to be able to have thumbnails on the page and then be able to click the images to see the full-size version. I am pulling the images and images info from an XML file. So, i did this so i could display them dynamically and so it would be easier to make changes later. Later, i am going to add functionality to upload new images to specific galleries (when i figure out how to do that as well). I am providing a link to download the project i am working on so you can see the code. I would appreciate any help with this! Thanks! URL to project: http://www.diminished4th.com/TestArtist.zip Ryan

  • SQL placeholder in WHERE IN issue, inserted strings fail.

    - by Alastair Pitts
    As part of my jobs, I need to writes SQL queries to connect to our PI database. To generate a query, I need to pass an array of tags (essentially primary keys), but these have to be inserted as strings. As this will be a modular query and used for multiple tags, a placeholder is being used. The query relies upon the use of the WHERE IN statement, which is where the placeholder is, like below: SELECT SUM(value * 5/1000) as "Hourly Flow [kL]" from piarchive..pitotal WHERE tag IN (?) AND time between ? and ? and timestep = '1d' and calcbasis = 'Eventweighted' and value <> '' The issue is the format in which the tags are to be passed in as. If I add them directly into the query (for testing), they go in the format (these are example numbers): '000000012','00000032','005050236','4560236' and the query looks like: SELECT SUM(value * 5/1000) as "Hourly Flow [kL]" from piarchive..pitotal WHERE tag IN ('000000012','00000032','005050236','4560236') AND time between ? and ? and timestep = '1d' and calcbasis = 'Eventweighted' and value <> '' which works. If I try and add the same tags into the placeholder, the query fails. If I only add 1 tag, with no quotes (using the placeholder), the query works. Why is this happening? Is there anyway around it?

  • BackgroundWorker and instance variables

    - by Alastair Pitts
    One thing that's always confused me is how a BackgroundWorker seems to have thread-safe access to the instance variables of the surrounding class. Given a basic class: public class BackgroundProcessor { public List<int> Items { get; private set; } public BackgroundProcessor(IEnumerable<int> items) { Items = new List<int>(items); } public void DoWork() { BackgroundWorker worker = new BackgroundWorker(); worker.RunWorkerCompleted += new RunWorkerCompletedEventHandler(worker_RunWorkerCompleted); worker.DoWork += new DoWorkEventHandler(worker_DoWork); worker.RunWorkerAsync(); } void worker_DoWork(object sender, DoWorkEventArgs e) { var processor = new ProcessingClass(); processor.Process(this.Points); //Accessing the instance variable } void worker_RunWorkerCompleted(object sender, RunWorkerCompletedEventArgs e) { //Stuff goes here } } Am I erroneous in my assumption the the call to processor.Process(this.Points); is a thread-safe call? How don't I get a cross-thread access violation? I'm sure it's obvious, but it always has confused me.

  • Updating Silverlight with data. JSON or WCF?

    - by Alastair Pitts
    We will be using custom Silverlight 4.0 controls on our ASP.NET MVC web page to display data from our database and was wondering what the most efficient method was? We will be having returned values of up to 100k records (of 2 properties per record). We have a test that uses the HTML Bridge from Javascript to Silverlight. First we perform a post request to a controller action in the MVC web app and return JSON. This JSON is then passed to the Silverlight where it is parsed and the UI updated. This seems to be rather slow, with the stored procedure (the select) taking about 3 seconds and the entire update in the browser about 10-15sec. Having a brief look on the net, it seems that WCF is another option, but not having used it, I wasn't sure of it's capability or suitability. Does anyone have any experiences or recommendations?

  • How do I attach a link (to a View) to an image in ASP.NET MVC?

    - by Ryan Pitts
    Ok, so here is my situation. I am creating a web application using ASP.NET MVC 2 using the C# language. I have programmed in HTML, CSS, and PHP for several years and I am very new to ASP.NET. The part that I am having trouble with is the image gallery. The setup: I have a link on the navigation bar that goes to a "Galleries" page. This page will show a list of galleries. Each gallery has a title, an image, and a description. All of this information is pulled from an XML file. I'm using the XML file like a database. I wanted to use this method so that i could easily update the list of galleries and have the updated XML file automatically be reflected by the website. Now, the galleries should link to an "Images" page. This page will display a list of images within the gallery based on what gallery was selected. This page will also pull from an XML file. The problem: I cannot seem to attach a dynamic link to the image? I am also stuck and not sure how to get the correct View to display. I know I need to do something with the controllers and models, right? I have some code if needed? I would greatly appreciate any help or direction for this! Thanks!

  • Innovation, Adaptability and Agility Emerge As Common Themes at ACORD LOMA Insurance Forum

    - by [email protected]
    Helen Pitts, senior product marketing manager for Oracle Insurance is blogging from the show floor of the ACORD LOMA Insurance Forum this week. Sessions at the ACORD LOMA Insurance Forum this week highlighted the need for insurance companies to think creatively and be innovative with their technology in order to adapt to continuously shifting market dynamics and drive business efficiency and agility.  LOMA President & CEO Robert Kerzner kicked off the day on Tuesday, citing how the recent downtown and recovery has impacted the insurance industry and the ways that companies are doing business.  He encouraged carriers to look for new ways to deliver solutions and offer a better service experience for consumers.  ACORD President & CEO Gregory Maciag reinforced Kerzner's remarks, noting how the industry's approach to technology and development of industry standards has evolved over the association's 40-year history and cited how the continued rise of mobile computing will change the way many carriers are doing business today and in the future. Drawing from his own experiences, popular keynote speaker and Apple Co-Founder Steve Wozniak continued this theme, delving into ways that insurers can unite business with technology.  "iWoz" encouraged insurers to foster an entrepreneurial mindset in a corporate environment to create a culture of creativity and innovation.  He noted that true innovation in business comes from those who have a passion for what they do.  Innovation was also a common theme in several sessions throughout the day with topics ranging from modernization of core systems, automated underwriting, distribution management, CRM and customer communications management.  It was evident that insurers have begun to move past the "old school" processes and systems that constrain agility, implementing new process models and modern technology to become nimble and more adaptive to the market.   Oracle Insurance executives shared a few examples of how insurers are achieving innovation during our Platinum Sponsor session, "Adaptive System Transformation:  Making Agility More Than a Buzzword." Oracle Insurance Senior Vice President and General Manager Don Russo was joined by Chuck Johnston, vice president, global strategy and alliances, and Srini Venkatasantham, vice president of product strategy.  The three shared how Oracle's adaptive solutions for insurance, with a focus on how the key pillars of an adaptive systems - configurable applications, accessible information, extensible content and flexible process - have helped insurers respond rapidly, perform effectively and win more business. Insurers looking to innovate their business with adaptive insurance solutions including policy administration, business intelligence, enterprise document automation, rating and underwriting, claims, CRM and more stopped by the Oracle Insurance booth on the exhibit floor.  It was a premiere destination for many participating in the exhibit hall tours conducted throughout the day. Finally, red was definitely the color of the evening at the Oracle Insurance "Red Hot" customer celebration at the House of Blues. The event provided a great opportunity for our customers to come together and network with the Oracle Insurance team and their peers in the industry.  We look forward to visiting more with of our customers and making new connections today. Helen Pitts is senior product marketing manager for Oracle Insurance.

UserSrn | QuestionId | ResponseScore ==================================== ABC2 | 1 | 5 ABC2 | 3 | 4 ABC4 | 16 | 3 ... What I am trying to do sounds pretty simple but I am struggling to find a neat, quick way of doing it. I want to create a sproc that takes an Srn and returns back all the staff under that Srn in the structure. If there is a score for QuestionId of 16 then that indicates a completed survey. I would like to return a line for the Srn entered (The top manager) with a count of completed surveys for the direct reports under that manager. Under that I would like each manager under the original manager with a count of completed surveys for each of their direct reports and so on. I would like to see the data as such below when I set the top manager to be Joe (ABC2). UserName | Completed | Total ============================ Joe | 2 | 2 Paul | 1 | 2 David | 0 | 2 TOTAL | 3 | 6

  • ACORD LOMA Session Highlights Policy Administration Trends

    - by [email protected]
    Helen Pitts, senior product marketing manager for Oracle Insurance, attended and is blogging from the ACORD LOMA Insurance Forum this week. Above: Paul Vancheri, Chief Information Officer, Fidelity Investments Life Insurance Company. Vancheri gave a presentation during the ACORD LOMA Insurance Systems Forum about the key elements of modern policy administration systems and how insurers can mitigate risk during legacy system migrations to safely introduce new technologies. When I had a few particularly challenging honors courses in college my father, a long-time technology industry veteran, used to say, "If you don't know how to do something go ask the experts. Find someone who has been there and done that, don't be afraid to ask the tough questions, and apply and build upon what you learn." (Actually he still offers this same advice today.) That's probably why my favorite sessions at industry events, like the ACORD LOMA Insurance Forum this week, are those that include insight on industry trends and case studies from carriers who share their experiences and offer best practices based upon their own lessons learned. I had the opportunity to attend a particularly insightful session Wednesday as Craig Weber, senior vice president of Celent's Insurance practice, and Paul Vancheri, CIO of Fidelity Life Investments, presented, "Managing the Dynamic Insurance Landscape: Enabling Growth and Profitability with a Modern Policy Administration System." Policy Administration Trends Growing the business is the top issue when it comes to IT among both life and annuity and property and casualty carriers according to Weber. To drive growth and capture market share from competitors, carriers are looking to modernize their core insurance systems, with 65 percent of those CIOs participating in recent Celent research citing plans to replace their policy administration systems. Weber noted that there has been continued focus and investment, particularly in the last three years, by software and technology vendors to offer modern, rules-based, configurable policy administration solutions. He added that these solutions are continuing to evolve with the ongoing aim of helping carriers rapidly meet shifting business needs--whether it is to launch new products to market faster than the competition, adapt existing products to meet shifting consumer and /or regulatory demands, or to exit unprofitable markets. He closed by noting the top four trends for policy administration either in the process of being adopted today or on the not-so-distant horizon for the future: Underwriting and service desktops New business automation Convergence of ultra-configurable and domain content-rich systems Better usability and screen design Mitigating the Risk When Making the Decision to Modernize Third-party analyst research from advisory firms like Celent was a key part of the due diligence process for Fidelity as it sought a replacement for its legacy policy administration system back in 2005, according to Vancheri. The company's business opportunities were outrunning system capability. Its legacy system had not been upgraded in several years and was deficient from a functionality and currency standpoint. This was constraining the carrier's ability to rapidly configure and bring new and complex products to market. The company sought a new, modern policy administration system, one that would enable it to keep pace with rapid and often unexpected industry changes and ahead of the competition. A cross-functional team that included representatives from finance, actuarial, operations, client services and IT conducted an extensive selection process. This process included deep documentation review, pilot evaluations, demonstrations of required functionality and complex problem-solving, infrastructure integration capability, and the ability to meet the company's desired cost model. The company ultimately selected an adaptive policy administration system that met its requirements to: Deliver ease of use - eliminating paper and rework, while easing the burden on representatives to sell and service annuities Provide customer parity - offering Web-based capabilities in alignment with the company's focus on delivering a consistent customer experience across its business Deliver scalability, efficiency - enabling automation, while simplifying and standardizing systems across its technology stack Offer desired functionality - supporting Fidelity's product configuration / rules management philosophy, focus on customer service and technology upgrade requirements Meet cost requirements - including implementation, professional services and licenses fees and ongoing maintenance Deliver upon business requirements - enabling the ability to drive time to market for new products and flexibility to make changes Best Practices for Addressing Implementation Challenges Based upon lessons learned during the company's implementation, Vancheri advised carriers to evaluate staffing capabilities and cultural impacts, review business requirements to avoid rebuilding legacy processes, factor in dependent systems, and review policies and practices to secure customer data. His formula for success: upfront planning + clear requirements = precision execution. Achieving a Return on Investment Vancheri said the decision to replace their legacy policy administration system and deploy a modern, rules-based system--before the economic downturn occurred--has been integral in helping the company adapt to shifting market conditions, while enabling growth in its direct channel sales of variable annuities. Since deploying its new policy admin system, the company has reduced its average time to market for new products from 12-15 months to 4.5 months. The company has since migrated its other products to the new system and retired its legacy system, significantly decreasing its overall product development cycle. From a processing standpoint Vancheri noted the company has achieved gains in automation, information, and ease of use, resulting in improved real-time data edits, controls for better quality, and tax handling capability. Plus, with by having only one platform to manage, the company has simplified its IT environment and is well positioned to deliver system enhancements for greater efficiencies. Commitment to Continuing the Investment In the short and longer term future Vancheri said the company plans to enhance business functionality to support money movement, wire automation, divorce processing on payout contracts and cost-based tracking improvements. It also plans to continue system upgrades to remain current as well as focus on further reducing cycle time, driving down maintenance costs, and integrating with other products. Helen Pitts is senior product marketing manager for Oracle Insurance focused on life/annuities and enterprise document automation.
