  • ASP.NET MVC Generic Partial

    - by gnome
    Is is possible to have a partial view inherit more than one model? I have three models (Contacts, Clients, Vendors) that all have address information (Address). In the interest of being DRY I pulled the address info into it's own model, Addresses. I created a partial create / update view of addresses and what to render this in other other three model's create / update views.

  • Adding Refresh Tag to View

    - by RJL
    I need a view to refresh automatically every 20 seconds, and have added the following code to the view header via the views GUI - with no success. The code (or portions of it) are simply displayed on the view and no updating is performed. I've tried omitting both and just the ending ?php statement. If someone can tell me the proper code to use, or a better approach at updating the view automatically, I'd be very appreciative. Thanks. print ";

  • How to build MVC Views that work with polymorphic domain model design?

    - by Johann de Swardt
    This is more of a "how would you do it" type of question. The application I'm working on is an ASP.NET MVC4 app using Razor syntax. I've got a nice domain model which has a few polymorphic classes, awesome to work with in the code, but I have a few questions regarding the MVC front-end. Views are easy to build for normal classes, but when it comes to the polymorphic ones I'm stuck on deciding how to implement them. The one (ugly) option is to build a page which handles the base type (eg. IContract) and has a bunch of if statements to check if we passed in a IServiceContract or ISupplyContract instance. Not pretty and very nasty to maintain. The other option is to build a view for each of these IContract child classes, breaking DRY principles completely. Don't like doing this for obvious reasons. Another option (also not great) is to split the view into chunks with partials and build partial views for each of the child types that are loaded into the main view for the base type, then deciding to show or hide the partial in a single if statement in the partial. Also messy. I've also been thinking about building a master page with sections for the fields that only occur in subclasses and to build views for each subclass referencing the master page. This looks like the least problematic solution? It will allow for fairly simple maintenance and it doesn't involve code duplication. What are your thoughts? Am I missing something obvious that will make our lives easier? Suggestions?

  • android listview set dynamically background color of views

    - by Sephy
    Hi everybody, I know that there have quite a lot of answers to similar questions but I couldn't find any solution to my question, so new topic : I'm creating a listview, with one basic view per row, my try is to change the background color of the view by .setbackgroundcolor, but nothing's doing the trick... I define an array of color at the beginning of my resources and i'm trying to display it, I also tried to put the array in the class, write the color like #00FF00, int, and I wanted to try 0x...... but as my colors are in an array, I can't do 0x+myColorsArray[i] because Eclipse tells me that it's not a proper hex color... I'm getting a bit desperate... thanks for any help

  • Segmented Control to change views

    - by Goods
    I have created an up/down arrow segmented control button on the right side of the navigation bar in my detail view. In a table based application, how can I use these up/down arrows to move through cells in the parent table? The apple "NavBar" sample code has an example of this but the controls are not functional. The iBird program has this functionality as well and it is very nice. Download the "iBird 15" program for free. Any thoughts? Thanks!

  • Appcelerator Titanium - auto height table views break with shortish text

    - by ceejayoz
    I posted this on the Appcelerator Titanium dev Q&A site, but maybe someone here has had this issue... KitchenSink 1.1 illustrates this issue. In table_view_api_auto_height.js, changing row: addRow(0,'This is some long text. This is some long text. This is some long text. This is some long text. This is some long text. This is some long text. This is some long text. This is some long text. This is some long text. This is some long text. This is some long text. This is some long text. This is some long text. This is some long text. This is some long text. This is some long text. This is some long text. This is some long text.'); to something like: addRow(0,'This is some long text. This is some long text.'); results in incorrect left padding on the row. See screenshot:

  • UISplitView show different views in the detail pane

    - by Mark
    How can I change the view in the Details pane of the UISplitView so that its a completely different view? Im having a fair amount of trouble understanding how its all wired up and where things should go at the moment, could someone please enlighten me? What I would love to be able to do is to show a specific view based on what the user has selected in the UITableView on the left pane (this view could be an image, or a more complex view of a news article, etc... many different options) then when the user turns the iPad into portrait view, that view that was in the details pane changes to be its equivalent portrait view version. Does this make sense? How on earth would I do that? Just to brainstorm, here is what I was thinking: Create a Split View project Create 2 NIBs for each view: (with accompanying view controllers???) * PortraitNewsStory * LandscapeNewsStory * PortraitImageBrowser * LandscapeImageBrowser * etc... Create a UISplitView control using XCode Capture when a user rotates the iPad (should this be done in the RootViewController.m ?) Change the view of the DetailViewController how should I do this? profit??? Thanks Mark

  • How do I present Prism module views?

    - by Maciek
    Heya, I'm writing a prism application, I've just created my 1st module, fired it all up and amazingly - it works. The application is going to grow soon(TM), and I'll be facing the need to host those modules in separate GUI elements. What type of GUI elements would you recommend to host the modules? Is it possible to data-bind a module to some control like a tab-control? How is it done? Is there some kind of a dock manager (similiar to AvalonDock) for Silverlight?

  • sharp architecture question - no strongly typed views

    - by csetzkorn
    Hi, I am trying to get my head around the sharp architecture and used the visual studio template as described on the web: http://wiki.sharparchitecture.net/VSTemplatesAndCodeGen.ashx This is all cool. Unfortunately, I cannot add a strongly typed view as easily as I am used to ‘under’ asp.net mvc. What can I do to ‘enable’ this in VS 2008 Prof? I have also installed asp.net mvc 2.0 and would like to reflect this in my ‘vs studio sharp environment’. Any pointers would be very much appreciated. Many thanks in advance. Best wishes, Christian

  • switch views using a button, going to a table view, iphone

    - by Jaime Rae
    My program has 4 buttons and each button calls a different table view. That works fine, but my problem is, the view controller I'm using brings up a table view that covers up my navigation bar and my tab bar. I need to replace that coding with something that will bring up a table and not cover up my nav and tab bars. Here is the coding I'm using: -(IBAction)buttonNorthWest { NorthWestViewController *nwController = [[NorthWestViewController alloc] initWithNibName:@"NorthWestView" bundle:nil]; self.nwViewController = nwController; [self.view insertSubview:nwViewController.view atIndex:0]; [self presentModalViewController:nwViewController animated:YES]; [nwController release]; } The [self presentModalViewController....] is the problem. Does anyone know how I can replace that code with something that keeps my nav and tab bars? Thanks, Jaime

  • Cannot get Google Analytics API to register page views on iPhone

    - by Sebastien
    I would like to gather usage statistics for my iPhone app using Google Analytics so I'm trying to configure it using the following tutorial: http://code.google.com/intl/fr-FR/apis/analytics/docs/tracking/mobileAppsTracking.html I think I did everything they indicate in the documentation, and I get no error on the iPhone side, but I don't see any visits in Google Analytics. - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions{ [self initGoogleAnalytics]; //... } -(void)initGoogleAnalytics{ [[GANTracker sharedTracker] startTrackerWithAccountID:[[NSBundle mainBundle] objectForInfoDictionaryKey:@"GoogleAnalyticsCode"] dispatchPeriod:-1 delegate:nil NSError *error; if(![[GANTracker sharedTracker] trackPageview:@"/home" withError:&error]){ NSLog(@"%@", [error localizedDescription], nil); } [[GANTracker sharedTracker] dispatch]; } Any idea why this is not working?

  • Good example usage of get_or _create in Django views and raising a Form error

    - by Rik Wade
    I would like to use get_or_create to check whether an object already exists in my database. If it does not, then it will be created. If it does exist, then I will not create the new object, but need to raise a form error to inform the user that they need to enter different data (for example, a different username). The view contains: p, created = Person.objects.get_or_create( email = registration_form.cleaned_data['email'], defaults = { 'creationDate': datetime.datetime.now(), 'dateOfBirth': datetime.date(1970,1,1) }) So 'p' will contain the existing Person if it exists, or the new Person if not. I would like to act on the boolean value in 'created' in order to skip over saving the Person and re-display the registration_form and raise an appropriate form validation error. The alternative I'm considering is doing a check in a custom Form validation method to see whether a Person exists with the data in the provided 'email' field, and just raising a validation error.

  • How to avoid re-drawing all views in an ArrayAdapter

    - by Hamy
    Hey all, I have an ArrayAdapter powering a ListView. I would like to change the data behind the ArrayAdapter and update the ListView's. Sounds like notifyDataSetChanged(); would be exactly what I am looking for, but it updates the entire ListView, and I would prefer to update on a row-by-row basis. Is there a way to do this with ArrayAdapter, or do I need to manage my data some other way if I want this functionality?

  • MkMapView setRegion animation prevents touch events on Annotation Views

    - by Vlad Gurovich
    Hi there! We have a MKmapView with a bunch of Image Annotation where each Image annotation responds to touch by overriding these methods of AnnotationView subclass: -(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event; -(void) touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event Our map region is updated using [MkMapView setRegion:animated:] whenever the new location is received and is far enough from the old location to make a difference. What I noticed is that if we set animated flag to YES the touches on our annotation are rarely detected(probably due to the fact that main thread is busy animating between two map regions. When we set animated flag to NO, everything is fine, but map transition may(or may not) become jerky. The question I have is whether this is an expected behavior of animated flag of [MkMapView setRegion:animated] function or whether there is a workaround for this issue. Thanks in advance

  • UIScrollView only works if the child views aren't hit

    - by dny238
    I have a scroll view that doesn't scroll right, I've simplified the code for below. It draws the view and some horizontal buttons that i add more stuff to in the real code. If you drag the whitespace between the buttons the view scrolls. If you happen to put your finger on a button, it won't scroll. After a related suggestion, I tried to add the delaysContentTouches = YES line, but it doesn't seem to make a difference. http://stackoverflow.com/questions/650437/iphone-uiscrollview-with-uibuttons-how-to-recreate-springboard What am I doing wrong? TIA, Rob Updated the code - (void)viewDidLoad { l = [self landscapeView]; [self.view addSubview:l]; [l release]; } - (UIScrollView *) landscapeView { // LANDSCAPE VIEW UIScrollView *landscapeView = [[UIScrollView alloc] initWithFrame:CGRectMake(0, 0, 320, 325)]; landscapeView.backgroundColor = [UIColor whiteColor]; landscapeView.delaysContentTouches = YES; NSInteger iMargin, runningY, n; iMargin = 3; runningY = iMargin; for (n = 1; n <= 38; n++) { //add day labels UIButton *templabel = [[UIButton alloc] initWithFrame:CGRectMake(iMargin,runningY,320 - ( 2 * iMargin),20)]; templabel.backgroundColor = [UIColor grayColor]; [landscapeView addSubview:templabel]; [templabel release]; runningY = runningY + 30; } landscapeView.contentSize = CGSizeMake( 320, runningY); return landscapeView; }

  • iphone cannot rotate views in TabBar controller

    - by Luc
    Hello, I am working on an application that consists of a TabBar controller. Within on of its tab, I have a subclass of UITableViewController, within this list I have a Core-plot graph in the first cell and some other data in the 4 following cells. When I return YES in the shouldAutorotateToInterfaceOrientation method, I would expect the autoresizing of the list view to happen, but... nothing. When I add some log in the willRotateToInterfaceOrientation method, they are not displayed. Is there something I missed ? Thanks a lot, Luc // Override to allow orientations other than the default portrait orientation. - (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation { // Return YES for supported orientations //return (interfaceOrientation == UIInterfaceOrientationPortrait); NSLog(@"Orientation"); return YES; } - (void)willRotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation duration:(NSTimeInterval)duration { [super willRotateToInterfaceOrientation:toInterfaceOrientation duration:duration]; NSLog(@"Rotating"); if (toInterfaceOrientation == UIInterfaceOrientationLandscapeRight) { NSLog(@"view land:%@", self.view); } if (toInterfaceOrientation == UIInterfaceOrientationPortrait) { NSLog(@"view portrait:%@", self.view); } }

  • ArrayIndexOutOfBoundsException with custom Android Adapter for multiple views in ListView

    - by Dan Watling
    I am attempting to create a custom Adapter for my ListView since each item in the list can have a different view (a link, toggle, or radio group), but when I try to run the Activity that uses the ListView I receive an error and the app stops. The application is targeted for the Android 1.6 platform. The code: public class MenuListAdapter extends BaseAdapter { private static final String LOG_KEY = MenuListAdapter.class.getSimpleName(); protected List<MenuItem> list; protected Context ctx; protected LayoutInflater inflater; public MenuListAdapter(Context context, List<MenuItem> objects) { this.list = objects; this.ctx = context; this.inflater = (LayoutInflater)this.ctx.getSystemService(Context.LAYOUT_INFLATER_SERVICE); } @Override public View getView(int position, View convertView, ViewGroup parent) { Log.i(LOG_KEY, "Position: " + position + "; convertView = " + convertView + "; parent=" + parent); MenuItem item = list.get(position); Log.i(LOG_KEY, "Item=" + item ); if (convertView == null) { convertView = this.inflater.inflate(item.getLayout(), null); } return convertView; } @Override public boolean areAllItemsEnabled() { return false; } @Override public boolean isEnabled(int position) { return true; } @Override public int getCount() { return this.list.size(); } @Override public MenuItem getItem(int position) { return this.list.get(position); } @Override public long getItemId(int position) { return position; } @Override public int getItemViewType(int position) { Log.i(LOG_KEY, "getItemViewType: " + this.list.get(position).getLayout()); return this.list.get(position).getLayout(); } @Override public int getViewTypeCount() { Log.i(LOG_KEY, "getViewTypeCount: " + this.list.size()); return this.list.size(); } } The error I receive: java.lang.ArrayIndexOutOfBoundsException at android.widget.AbsListView$RecycleBin.addScrapView(AbsListView.java:3523) at android.widget.ListView.measureHeightOfChildren(ListView.java:1158) at android.widget.ListView.onMeasure(ListView.java:1060) at android.view.View.measure(View.java:7703) I do know that the application is returning from getView and everything seems in order. Any ideas on what could be causing this would be appreciated. Thanks, -Dan

  • Custom UITableViewCell not properly hiding views

    - by adamweeks
    I am using apple's custom table view cell code and modifying the drawRect code within the cell's view to look like I want it to. I've changed it to have some UILabels as well as a UIProgressView. If the data the cell is being built on doesn't have a certain field, I want the UIProgressView to be hidden. This works for a little while, but when a cell gets requeued, the progress view will start displaying again, even when I set it to hidden = YES. I've tried just not creating the ProgressView unless the data was there and that didn't work either. I thought the answer was in the [self setNeedsDisplay] but that doesn't seem to help. Here is the code for the progressview from drawRect that continues to be displayed: UIProgressView *c1Progress = [[UIProgressView alloc]initWithFrame:CGRectMake(20.0, 70.0, 280.0, 12.0)]; float iProgress = (value / target); c1Progress.progress = iProgress; if (!dataExists) { c1Progress.hidden = YES; } [self addSubview:criteria1Progress]; [c1Progress release];

  • Metamorphs Messing Up CSS in Ember.js Views

    - by Austin Fatheree
    I'm using Ember.js / handlebars to loop through a collection and spit out some items that I'd like bootstrap to handle nice and responsive like. Here is the issue: The bootstrap-responsive css has some declrations in it like: .row-fluid > [class*="span"]:first-child { margin-left: 0; } and .row-fluid:before, .row-fluid:after { display: table; content: ""; } These rules seem to target the first children. When I loop through my collection in handlebars I end up with a bunch of metamorph code around my items: <div class="row-fluid"> {{#each restaurantList}} {{view GS.vHomePageRestList content=this class="span6"}} {{/each}} </div> Here is what is produced: <div class="row-fluid"> <script id="metamorph-9-start" type="text/x-placeholder"></script> <script id="metamorph-104-start" type="text/x-placeholder"></script> <div id="ember2527" class="ember-view span6"> My View </div> <script id="metamorph-104-end" type="text/x-placeholder"></script> <script id="metamorph-105-start" type="text/x-placeholder"></script> <div id="ember2574" class="ember-view span6"> My View 2 </div> <script id="metamorph-105-end" type="text/x-placeholder"></script> <script id="metamorph-9-end" type="text/x-placeholder"></script> </div> So my question is this: 1. How can I tell css to ignore script tags? or 2. How can I edit the css bindings so that they skip over script tags when selecting the first or first child? or 3. How can I structure this so that Ember uses fewer/no metamorph tags? Here is a fiddle: http://jsfiddle.net/skilesare/SgwsJ/
