• Auto-generate WebControls

  - by Adrian K

  I want to generate .net code from a template so that it more rapid, so lazy developers (and I mean that in the nicest possible way!) don't have to write them in the IDE, compile them, etc... I know I can roll my own tool which generates the code using reflection (by reading in some text file, etc), but I just wondered if there was an easier than starting from scratch since this is what ASP.NET basically does already; so is there anyway to leverage this? E.g. to quote Peter A. Bromberg: Even an ASPX page with no code on it gets turned into an instance of the System.Web.UI.Page class. The page is parsed by the ASP.NET engine when it is first requested, and then its JIT compiled version is cached in the Temporary ASP.NET Files folder as long as the application is running and the .aspx page hasn't been changed. Ideally I want to auto-generate WebControls, but examples of anything closely related will do. C# Examples preferred also, but anything considered :)

• Refreshing a binding that uses a value converter

  - by Hadi Eskandari

  I have a WPF UI that is bound to an object. I'm using a ValueConverter to convert a property to a specific image by a business rule: public class ProposalStateImageConverter : IValueConverter { public object Convert(object value, Type targetType, object parameter, CultureInfo culture) { var proposal = value as Proposal; var basePath = "pack://application:,,,/ePub.Content;component/Images/General/Flag_{0}.png"; string imagePath; if(proposal.Invoice != null) { imagePath = string.Format(basePath, "Good"); } else { imagePath = string.Format(basePath, "Warning"); } var uri = new Uri(imagePath); var src = uri.GetImageSource(); //Extention method return src; } } It is working fine, but later, when the object's state changes, I want to refresh the image and make the value converter reevaluate. How is this possible?

• View centric design with Django

  - by wishi_

  Hi! I'm relatively new to Django and I'm designing a website that primarily needs usability experience, speaking of optimized CSS, HTML5 and UI stuff. It's very easy to use Django for data/Model centric design. Just designing a couple of Python classes and ./manage.py syncdb - there's your Model. But I'm dealing with a significant amount of View centric challenges. (Different user classes, different tasks, different design challenges.) The official Django tutorial cursorily goes through using a "Template". Is there any Design centric guide for Django, or a set of Templates that are ready and useable? I don't want to start from scratch using JS, HTML5, Ajax and everything. From the Model layer perspective Django is very rapid and delivering a working base system. I wonder whether there's something like that for the Views.

• QML 5.3 iOS compilation of pure QML app

  - by Nathaniel Johnson

  I have an application written in QML. Initially, I used the standard C++ bootstrap for the app. int main(int argc, char *argv[]) { QApplication app(argc, argv); // A bunch of components and data models written in C++ QQmlApplicationEngine engine; engine.load(QUrl(QStringLiteral("qrc:///main.qml"))); return app.exec(); } The bulk of the app is in QML and the more I work with QML, the happier I am with it and the more I feel comfortable converting the C++ pieces to QML. So, it comes to one risk that I wanted to ask about. If I convert the app to a pure QML application like the kind generated by the Qt Quick UI application wizard with no C++ and designed to be run with qmlscene will I be able to compile it for iOS when the time to port it comes or will I end up just converting it back to the C++ loader form? TL;DR Can pure QML (no C++) apps be compiled and run on iOS devices?

• jQuery - events won't fire for dynamically created tab elements..

  - by Amit

  Hi, I am using jQuery UI Tabs. <div id="tabs"> <ul id="tablist"> <li><a href="#fragment-1"><span>One</span></a></li> </ul> </div> I have a button that adds new tabs. I use the following code: var newTabId = $('#tabs').tabs('option', 'selected') + 1; $('#tabs').tabs("add",'someUrl.htm','New Tab',newTabId); (Tab will be added next to the currently selected tab) Now none of the newly added tabs fire any events such as a click or hover $('#tablist li').click(function(){ alert('test message'); }); But events fire properly for the tabs that were there in the initial source code. How to resolve?

• Hook for redraw event in Blackberry

  - by Bendlas

  Is there a way to add a redraw callback to a live screen object, i.e. not via inheritance? Reasoning: I want to draw an overlay from an extension for widget sdk (substituting defunct position:absolute), so the screen is created by the bbwp stub. I can get it by Ui.getUiEngine().getActiveScreen() and draw on it quite nicely, but I need a way to redraw when appropriate. Note: I've abandoned the approach to push the overlay as a screen, because i couldn't make it transparent / find a way to pass events through.

• Accessing Linq data in telerik grid ItemCreated method

  - by Jack

  Not sure if the title of this question makes sense, but here's my problem: I have a telerik grid bound to a Linq data object, however, I limit the fields returned: <IQueryable>filter = data.Select(x => new {x.ID, x.Name, x.Age}); I would like to access these fields in the ItemCreated method of the grid: protected void rgPeople_ItemCreated(object sender, GridItemEventArgs e) { Telerik.Web.UI.GridDataItem item = (GridDataItem)e.Item; ?????? Person = (???????)e.Item.DataItem; } What do I declare ?????? as so that I can use: String ID = Person.ID; String Name = Person.Name; etc

• How do I create a MessageBox in C# ?

  - by Nick Stinemates

  I have just installed C# for the first time, and at first glance it appears to be very similar to VB6. I decided to start off by trying to make a 'Hello, World!' UI Edition. I started in the Form Designer and made a button named "Click Me!" proceeded to double-click it and typed in MessageBox("Hello, World!"); I received the following error: MessageBox is a 'type' but used as a 'variable' Fair enough, it seems in C# MessageBox is an Object. I tried the following MessageBox a = new MessageBox("Hello, World!"); I received the following error: MessageBox does not contain a constructor that takes '1' arguments Now I am stumped. Please help.

• Unhandled exceptions in BackgroundWorker

  - by edg

  My WinForms app uses a number of BackgroundWorker objects to retrieve information from a database. I'm using BackgroundWorker because it allows the UI to remain unblocked during long-running database queries and it simplifies the threading model for me. I'm getting occasional DatabaseExceptions in some of these background threads, and I have witnessed at least one of these exceptions in a worker thread while debugging. I'm fairly confident these exceptions are timeouts which I suppose its reasonable to expect from time to time. My question is about what happens when an unhandled exception occurs in one of these background worker threads. I don't think I can catch an exception in another thread, but can I expect my WorkerCompleted method to be executed? Is there any property or method of the BackgroundWorker I can interrogate for exceptions?

• Architectural decision : QT or Eclipse Platform ?

  - by umanga

  We are in the process of designing a tool to be used with HDEM(High Definition Electron Microscope).We get stacks of 2D images from HDEM and first step is 'detecting borders' on the sections.After detecting edges of 2D slices ,next step is construct the 3D model using these 2D slices. This 'border detecting' algorithm(s) is/are implemented by one of professor and he has used and suggests to use C.(to gain high performance and probably will parallelise in future) We have to develop comprehensive UI ,3D viewer ,2D editor...etc and use this algorithm. Application should support usual features like project save/open.Undo,Redo...etc Our technology decisions are: A) Build entire platform from the scratch using QT. B) Use Eclipse Platform Our concerns are, if we choose A) we can easily integrate the 'border detecting' algorithm(s) because the development environment is C/C++ But we have to implement the basic features from the scratch. If we choose B) we get basic features from the Eclipse platform , but integrating C libraries going to be a tedious task. Any suggestions on this?

• Adobe After Effects Plugin With Cocoa (Overriding malloc)

  - by mustISignUp

  Messing about a bit, i have a working Adobe After Effects plugin with a bit of Obj-c / Cocoa in it (NSArray and custom objects - not ui stuff). The SDK guide states:- Always use After Effects memory allocation functions. In low-memory conditions (such as during RAM preview), it’s very important that plug-ins not compete with After Effects for OS memory, and deal gracefully with out-of-memory conditions. Failing to use our functions can cause lock-ups, crashes, and tech support calls. Don’t do that. If you’re wrapping existing C++ code, overloading new and delete to use our functions will save substantial reimplementation. On Windows, derive all classes from a common base class which implements new and delete. so my question.. is something compatible with the above statement possible in Obj-c?

• Is ASP.Net Server Control, Postback Architecture failed in current Web 2.0 World.

  - by Lalit

  What i am looking around me is the drastically change in ASP.Net Architecture. More and more company are following the approach of JSON based wcf service in middle tier. Plain HTML based UI tier with JQuery/Ajax. No Postback at all, This contradicts the Default behaviour of Asp.Net Server Control/Code Behind Event handler/Postback. I am a Asp.Net Web Developer for around 4 years, and concerned about the future of ASP.Net. Is the Default Architecture of ASP.Net is Outdated at all? Does MVC or ASP.Net 4.0 Tries to solve the Issue?

• How to change the layout of the CreateUserWizard control?

  - by Bazzz

  How to change just the layout (template) of the CreateUserWizard control programmatically? I would to define another layout (not using the horrid table) but continue to use all the event handling and the creation of the user of the CreateUserWizard control. Just for reference, the following code doesn't work, and produces an unexpected result not representing my Template at all. The "InstantiateIn" method of the ITemplate is not called. public partial class b : System.Web.UI.Page { protected void Page_Init(object sender, EventArgs e) { CreateUserWizard createUserWizard = new CreateUserWizard(); createUserWizard.CreateUserStep.ContentTemplate = new Template(); Panel1.Controls.Add(createUserWizard); } } public class Template : ITemplate { void ITemplate.InstantiateIn(Control container) { container.Controls.Add(new TextBox() { ID = "UserName" }); container.Controls.Add(new TextBox() { ID = "Password" }); container.Controls.Add(new TextBox() { ID = "ConfirmPassword" }); container.Controls.Add(new TextBox() { ID = "Email" }); container.Controls.Add(new PlaceHolder() { ID = "ErrorMessage" }); } } }

• multiple occurences of HandleCreated for a single control

  - by Asher

  I’m using control that needs to be register to asynchronous events. The events will be raised in the UI thread using the ISynchronizeInvoke interface implemented by WinForms controls I can’t register to the event at the constructor because it will allow calling the event handler before the control is fully created. during which calls to ISynchronizeInvoke are not allowed. Solution to that problem is to use the perform the asynchronous event registration from an event handler to the HandleCreated instead of registering from the constructor. however, this poses another issue, in some scenations the HandleCreated event is raised multiple times as result of change at the control state. For example, each changing of the “RightToLeft” property causes a WMCreate message that cause raising the “HandleCreated” event. How can I prevent the multiply times of event rising? Is there is another way to know when the control is created and display for the first time? I can keep a boolean flag in the HandleCreated, however it feels like a hack and I am wondering if there is a better way to handle this issue.

• Is it faster to do the pages first and CSS second, or should I do them at the same time?

  - by Fred Haslam

  I have been tasked with building a new web project from scratch, with the exception of reusing CSS files (the look and feel) from an existing project. In the past I have always completed development of the functionality and the web-ui before considering the appearance. This is mostly due to CSS development overlapping with the tail end of the project. I now have the opportunity to integrate a static set of CSS as I build the application. I have no experience with this circumstance. Would it be faster to develop the project and web-pages first, then integrate the CSS; or would it be faster to integrate the CSS as part of page development?

• Approaches to wrapping access to functionality in .NET MVC?

  - by Kevin

  What are some different solutions to wrapping access to functionality within a .NET MVC application? For example, I have six tabs that represent different areas of the application and within area 1, there is the ability to add, edit, upload, whatever. I need a central way to say: Build some dictionary of what the user can do Wrap tabs, buttons, links, etc, validate the user can access this piece of functionality and show/hide appropriately. I know I can restrict access to actions via action filters and roles, but what about from the UI? Any help would be appreciated. I am sure I am not the only one who has needed to do this, thanks!

• TextBox.TextChanged & ICommandSource

  - by Brad Leach

  I am following the M-V-VM pattern for my WPF UI. I would like to hook up a command to the TextChanged event of a TextBox to a command that is in my ViewModel class. The only way I can conceive of completing this task is to inherit from the TextBox control, and implement ICommandSource. I can then instruct the command to be fired from the TextChanged event. This seems to be too much work for something which appears to be so simple. Is there an easier way (than subclassing the TextBox and implementing ICommandSource) to hook up the TextChanged event to my ViewModel class?

• Detect if touch device

  - by Kilnr

  Hello, I'm writing a MIDlet using the Kuix UI toolkit, and I want to make changes to the toolkit depending on whether the current device is a touch screen device. (These changes include making buttons bigger, for easier tapping.) Is there a way to detect whether the device has a touch screen using J2ME (MIDP 2)? [edit] as a (crappy) workaround I check for the screen height instead. A screen width a height of higher than 240 is likely a touch screen... Please let me know if there are any more effective ways.

• UISplitViewController: how to get toolbar if details controller is UITableView?

  - by Krumelur

  Hi, I checked out Apple's example on how to exchange detail views in the UISplitViewController (http://developer.apple.com/library/ios/#samplecode/MultipleDetailViews/Introduction/Intro.html#//apple_ref/doc/uid/DTS40009775) and it seems that they put the UIToolbar in every detail controller. Then, if the device is rotated, they hide the toolbar or show it and add a popover button which will show the root controller. I'd like to adopt this pattern to show my root controller in a popover using a button in the toolbar, but unfortunately, my detail controllers are all UITableViewControllers and they do not allow adding other UI elements than a table view. So how do I deal with that? Is there an example around? René

• How to fetch data for AutoCompleteTextView in separate thread?

  - by Laimoncijus

  For my AutoCompleteTextView I need to fetch the data from a webservice. As it can take a little time I do not want UI thread to be not responsive, so I need somehow to fetch the data in a separate thread. For example, while fetching data from SQLite DB, it is very easy done with CursorAdapter method - runQueryOnBackgroundThread. I was looking around to other adapters like ArrayAdapter, BaseAdapter, but could not find anything similar... Is there an easy way how to achieve this? I cannot simply use ArrayAdapter directly, as the suggestions list is dynamic - I always fetch the suggestions list depending on user input, so it cannot be pre-fetched and cached for further use... If someone could give some tips or examples on this topic - would be great!

• Using file-path to images stored within the Application Settings

  - by Bill

  I am trying to develop an application that uses a number of images that are stored in a seperate remote file location. The file-paths to the UI elements are stored within the Application Settings. Although I understand how to access and use the file-path from Settings in C# (Properties.Settings.Default.pathToGridImages + "OK.png"), I am at a loss to figure out how to utilize the Settings paths in WPF, and can only seem to access the file if I include the file-path, such as: <Grid.Background> <ImageBrush ImageSource="C:\Skins\bottomfill.png" TileMode="Tile" /> </Grid.Background> I would have thought that concatenating "Properties.Settings.Default.pathToGridImages" with "bottomfill.png" in WPF could be done much like it can be done in C#. Can anyone please point me in the right direction?

• Not able to override CSS within IFrame

  - by Madhur Ahuja

  I am using disqus comments for my jekyll blog with some CSS styles overriden in my stylesheet and used to work perfectly. Recently, disqus has introduced a new UI for their comments system which has completely broken the font colors. Since my site has dark background, I am trying to apply styles based on new disqus HTML structure generated. However, it seems that none of my styles get applied. It seems that is because disqus is loaded within iframe. Any ideas how can I fix the font colors. Example of the post: http://www.madhur.co.in/blog/2012/03/27/codeplexmovegit.html UPDATE Based on this question How to apply CSS to iFrame? it seems that you cannot style a child IFrame cross domain. I am wondering how it used to work earlier. Disqus even has documentation on it http://docs.disqus.com/help/69/

• Multiple Controls on a Page with Multiple Instances of Javascript

  - by mattdell

  I have created a Web Control in ASP for use in integrating with Telligent CommunityServer. The control is written in ASP with some 10 lines of C# backend for controlling visibility of the UI elements based on permissions, but I'd say 90% of the functionality is straight-up Javascript. The control works beautifully, until you drop two instances of the Control on the same page--since they reference the exact same Javascript functions, only one control works. How can I take this functionality that I have, this 1200 lines of Javascript, and make it so that each instance of the control can reference its each unique instance of Javascript?
