  • ASP.NET MVC 2 loading partial view using jQuery - no client side validation

    - by brainnovative
    I am using jQuery.load() to render a partial view. This part looks like this: $('#sizeAddHolder').load( '/MyController/MyAction', function () { ... }); The code for actions in my controller is the following: public ActionResult MyAction(byte id) { var model = new MyModel { ObjectProp1 = "Some text" }; return View(model); } [HttpPost] public ActionResult MyAction(byte id, FormCollection form) { // TODO: DB insert logic goes here var result = ...; return Json(result); } I am returning a partial view that looks something like this: <% using (Html.BeginForm("MyAction", "MyController")) {%> <%= Html.ValidationSummary(true) %> <h3>Create my object</h3> <fieldset> <legend>Fields</legend> <div class="editor-label"> <%= Html.LabelFor(model => model.ObjectProp1) %> </div> <div class="editor-field"> <%= Html.TextBoxFor(model => model.Size.ObjectProp1) %> <%= Html.ValidationMessageFor(model => model.ObjectProp1) %> </div> div class="editor-label"> <%= Html.LabelFor(model => model.ObjectProp2) %> </div> <div class="editor-field"> <%= Html.TextBoxFor(model => model.ObjectProp2) %> <%= Html.ValidationMessageFor(model => model.ObjectProp2) %> </div> <p> <input type="submit" value="Create" /> </p> </fieldset> <% } %> Client side validation does not work in this case. What is more the script that contains validation messages also isn't included in the view that's returned. Both properties in my model class have Required and StringLength attributes. Is there any way to trigger client side validation in a view which has been loaded like this?

  • Memory leak on CollectionView.View.Refresh

    - by Dabblernl
    I have defined my binding thus: <TreeView ItemsSource="{Binding UsersView.View}" ItemTemplate="{StaticResource MyDataTemplate}" /> The CollectionViewSource is defined thus: private ObservableCollection<UserData> users; public CollectionViewSource UsersView{get;set;} UsersView=new CollectionViewSource{Source=users}; UsersView.SortDescriptions.Add( new SortDescription("IsLoggedOn",ListSortDirection.Descending); UsersView.SortDescriptions.Add( new SortDescription("Username",ListSortDirection.Ascending); So far, so good, this works as expected: The view shows first the users that are logged on in alphabetical order, then the ones that are not. However, the IsLoggedIn property of the UserData is updated every few seconds by a backgroundworker thread and then the code calls: UsersView.View.Refresh(); on the UI thread. Again this works as expected: users that log on are moved from the bottom of the view to the top and vice versa. However: Every time I call the Refresh method on the view the application hoards 3,5MB of extra memory, which is only released after application shutdown (or after an OutOfMemoryException...) I did some research and below is a list of fixes that did NOT work: The UserData class implements INotifyPropertyChanged Changing the underlying users collection does not make any difference at all: any IENumerable<UserData as a source for the CollectionViewSource causes the problem. -Changing the ColletionViewSource to a List<UserData (and refreshing the binding) or inheriting from ObservableCollection to get access to the underlying Items collection to sort that in place does not work. I am out of ideas! Help? EDIT: I found it: The Resource MyDataTemplate contains a Label that is bound to a UserData object to show one of its properties, the UserData objects being handed down by the TreeView's ItemsSource. The Label has a ContextMenu defined thus: <ContextMenu Background="Transparent" Width="325" Opacity=".8" HasDropShadow="True"> <PrivateMessengerUI:MyUserData IsReadOnly="True" > <PrivateMessengerUI:MyUserData.DataContext> <Binding Path="."/> </PrivateMessengerUI:MyUserData.DataContext> </PrivateMessengerUI:MyUserData> </ContextMenu> The MyUserData object is a UserControl that shows All properties of the UserData object. In this way the user first only sees one piece of data of a user and on a right click sees all of it. When I remove the MyUserData UserControl from the DataTemplate the memory leak disappears! How can I still implement the behaviour as specified above?

  • Cancel UITouch Events When View Covered By Modal UIViewController

    - by kkrizka
    Hi there, I am writing an application where the user has to move some stuff on the screen using his fingers and drop them. To do this, I am using the touchesBegan,touchesEnded... function of each view that has to be moved. The problem is that sometimes the views are covered by a view displayed using the [UIViewController presentModalViewController] function. As soon as that happens, the UIView that I was moving stops receiving the touch events, since it was covered up. But there is no event telling me that it stopped receiving the events, so I can reset the state of the moved view. The following is an example that demonstrates this. The functions are part of a UIView that is being shown in the main window. It listens to touch events and when I drag the finger for some distance, it presents a modal view that covers everything. In the Run Log, it prints what touch events are received. - (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event { NSLog(@"touchesBegan"); touchStart=[[touches anyObject] locationInView:self]; } - (void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event { CGPoint touchAt=[[touches anyObject] locationInView:self]; float xx=(touchAt.x-touchStart.x)*(touchAt.x-touchStart.x); float yy=(touchAt.y-touchStart.y)*(touchAt.y-touchStart.y); float rr=xx+yy; NSLog(@"touchesMoved %f",rr); if(rr > 100) { NSLog(@"Show modal"); [viewController presentModalViewController:[UIViewController new] animated:NO]; } } - (void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event { NSLog(@"touchesEnded"); } - (void)touchesCancelled:(NSSet *)touches withEvent:(UIEvent *)event { NSLog(@"touchesCancelled"); } But when I test the application and trigger the modal dialog to be displayed, the following is the output in the Run Log. [Session started at 2010-03-27 16:17:14 -0700.] 2010-03-27 16:17:18.831 modelTouchCancel[2594:207] touchesBegan 2010-03-27 16:17:19.485 modelTouchCancel[2594:207] touchesMoved 2.000000 2010-03-27 16:17:19.504 modelTouchCancel[2594:207] touchesMoved 4.000000 2010-03-27 16:17:19.523 modelTouchCancel[2594:207] touchesMoved 16.000000 2010-03-27 16:17:19.538 modelTouchCancel[2594:207] touchesMoved 26.000000 2010-03-27 16:17:19.596 modelTouchCancel[2594:207] touchesMoved 68.000000 2010-03-27 16:17:19.624 modelTouchCancel[2594:207] touchesMoved 85.000000 2010-03-27 16:17:19.640 modelTouchCancel[2594:207] touchesMoved 125.000000 2010-03-27 16:17:19.641 modelTouchCancel[2594:207] Show modal Any suggestions on how to reset the state of a UIView when its touch events are interrupted by a modal view?

  • Multiple View App shows Blank Screen in Simulator

    - by Brett Coburn
    Hello; I am developing a simple app that first shows a menu screen, and when a button is pressed, a game screen appears. I was able to develop the game screen without any issues, but when I changed the code to first display the menu, the simulator showed a blank screen.

  • Silverlight with MVVM Inheritance: ModelView and View matching the Model

    - by moonground.de
    Hello Stackoverflowers! :) Today I have a special question on Silverlight (4 RC) MVVM and inheritance concepts and looking for a best practice solution... I think that i understand the basic idea and concepts behind MVVM. My Model doesn't know anything about the ViewModel as the ViewModel itself doesn't know about the View. The ViewModel knows the Model and the Views know the ViewModels. Imagine the following basic (example) scenario (I'm trying to keep anything short and simple): My Model contains a ProductBase class with a few basic properties, a SimpleProduct : ProductBase adding a few more Properties and ExtendedProduct : ProductBase adding another properties. According to this Model I have several ViewModels, most essential SimpleProductViewModel : ViewModelBase and ExtendedProductViewModel : ViewModelBase. Last but not least, according Views SimpleProductView and ExtendedProductView. In future, I might add many product types (and matching Views + VMs). 1. How do i know which ViewModel to create when receiving a Model collection? After calling my data provider method, it will finally end up having a List<ProductBase>. It containts, for example, one SimpleProduct and two ExtendedProducts. How can I transform the results to an ObservableCollection<ViewModelBase> having the proper ViewModel types (one SimpleProductViewModel and two ExtendedProductViewModels) in it? I might check for Model type and construct the ViewModel accordingly, i.e. foreach(ProductBase currentProductBase in resultList) if (currentProductBase is SimpleProduct) viewModels.Add( new SimpleProductViewModel((SimpleProduct)currentProductBase)); else if (currentProductBase is ExtendedProduct) viewModels.Add( new ExtendedProductViewModels((ExtendedProduct)currentProductBase)); ... } ...but I consider this very bad practice as this code doesn't follow the object oriented design. The other way round, providing abstract Factory methods would reduce the code to: foreach(ProductBase currentProductBase in resultList) viewModels.Add(currentProductBase.CreateViewModel()) and would be perfectly extensible but since the Model doesn't know the ViewModels, that's not possible. I might bring interfaces into game here, but I haven't seen such approach proven yet. 2. How do i know which View to display when selecting a ViewModel? This is pretty the same problem, but on a higher level. Ended up finally having the desired ObservableCollection<ViewModelBase> collection would require the main view to choose a matching View for the ViewModel. In WPF, there is a DataTemplate concept which can supply a View upon a defined DataType. Unfortunately, this doesn't work in Silverlight and the only replacement I've found was the ResourceSelector of the SLExtensions toolkit which is buggy and not satisfying. Beside that, all problems from Question 1 apply as well. Do you have some hints or even a solution for the problems I describe, which you hopefully can understand from my explanation? Thank you in advance! Thomas

  • Problem with Landscape and Portrait view in a TabBar Application

    - by JoshD
    I have an TabBar app that I would like to be in landscape and portrait. The issue is when I go to tab 2 make a selection from my table then select tab 1 and rotate the device, then select tab 2 again the content does not know that the device rotated and will not display my custom orientated content correctly. I am trying to write a priovate method that tells the view what orientation it is currently in. IN viewDidLoad I am assuming it is in portrait but in shouldAutoRotate I have it looking in the private method for the correct alignment of the content. Please Help!! Here is my code: #import "DetailViewController.h" #import "ScheduleTableViewController.h" #import "BrightcoveDemoAppDelegate.h" #import "Constants.h" @implementation DetailViewController @synthesize CurrentLevel, CurrentTitle, tableDataSource,logoName,showDescription,showDescriptionInfo,showTime, showTimeInfo, tableBG; - (void)layoutSubviews { showLogo.frame = CGRectMake(40, 20, 187, 101); showDescription.frame = CGRectMake(85, 140, 330, 65); showTime.frame = CGRectMake(130, 10, 149, 119); tableBG.frame = CGRectMake(0, 0, 480, 320); } /* // The designated initializer.

  • Showing ImageView next to TextView in a ListView

    - by KDEx
    So I have a listview that is displaying correctly. When the item is "turned on" the text is white and when it's turned off it's grey. That part all functions great. However when I add the ImageView into the mix I get a null pointer exception. I don't understand why. I've tried using bitmaps as well and get the same problem. Here is some code: @Override public void bindView(View view, Context context, Cursor cursor) { TextView rRule = (TextView) view.findViewById(R.id.rule_text); TextView rType = (TextView) view.findViewById(R.id.rule_type); ImageView iChecked = (ImageView) view.findViewById(R.id.checkBox); String ruleName = cursor.getString(1); int ruleType = cursor.getInt(2); String ruleEnabled = cursor.getString(3); switch (ruleType) { /*...some irrelevant code */ } if (ruleEnabled.equals("true")) { rRule.setTypeface(null, Typeface.BOLD); rRule.setTextColor(Color.WHITE); iChecked.setVisibility(View.VISIBLE); //line 271 } else if (ruleEnabled.equals("false")) { rRule.setTypeface(null, Typeface.NORMAL); rRule.setTextColor(Color.GRAY); iChecked.setVisibility(View.GONE); } rRule.setText(ruleName); } Per request the error log: (Sorry was under the impression null pointers dont say anything helpful..I know the error is the imageview) 06-29 10:29:02.777: E/AndroidRuntime(29516): FATAL EXCEPTION: main 06-29 10:29:02.777: E/AndroidRuntime(29516): java.lang.NullPointerException 06-29 10:29:02.777: E/AndroidRuntime(29516): at com.company.app.DefaultRulesList$RulesAdapter.bindView(DefaultRulesList.java:271) 06-29 10:29:02.777: E/AndroidRuntime(29516): at com.company.app.DefaultRulesList$RulesAdapter.newView(DefaultRulesList.java:284) 06-29 10:29:02.777: E/AndroidRuntime(29516): at android.widget.CursorAdapter.getView(CursorAdapter.java:246) 06-29 10:29:02.777: E/AndroidRuntime(29516): at android.widget.AbsListView.obtainView(AbsListView.java:2033) 06-29 10:29:02.777: E/AndroidRuntime(29516): at android.widget.ListView.makeAndAddView(ListView.java:1772) 06-29 10:29:02.777: E/AndroidRuntime(29516): at android.widget.ListView.fillDown(ListView.java:672) 06-29 10:29:02.777: E/AndroidRuntime(29516): at android.widget.ListView.fillFromTop(ListView.java:732) 06-29 10:29:02.777: E/AndroidRuntime(29516): at android.widget.ListView.layoutChildren(ListView.java:1625) 06-29 10:29:02.777: E/AndroidRuntime(29516): at android.widget.AbsListView.onLayout(AbsListView.java:1863) 06-29 10:29:02.777: E/AndroidRuntime(29516): at android.view.View.layout(View.java:11278) 06-29 10:29:02.777: E/AndroidRuntime(29516): at android.view.ViewGroup.layout(ViewGroup.java:4224) 06-29 10:29:02.777: E/AndroidRuntime(29516): at android.widget.LinearLayout.setChildFrame(LinearLayout.java:1628) 06-29 10:29:02.777: E/AndroidRuntime(29516): at android.widget.LinearLayout.layoutVertical(LinearLayout.java:1486) 06-29 10:29:02.777: E/AndroidRuntime(29516): at android.widget.LinearLayout.onLayout(LinearLayout.java:1399) 06-29 10:29:02.777: E/AndroidRuntime(29516): at android.view.View.layout(View.java:11278) 06-29 10:29:02.777: E/AndroidRuntime(29516): at android.view.ViewGroup.layout(ViewGroup.java:4224) 06-29 10:29:02.777: E/AndroidRuntime(29516): at android.widget.FrameLayout.onLayout(FrameLayout.java:431) 06-29 10:29:02.777: E/AndroidRuntime(29516): at android.view.View.layout(View.java:11278) 06-29 10:29:02.777: E/AndroidRuntime(29516): at android.view.ViewGroup.layout(ViewGroup.java:4224) 06-29 10:29:02.777: E/AndroidRuntime(29516): at android.widget.LinearLayout.setChildFrame(LinearLayout.java:1628) 06-29 10:29:02.777: E/AndroidRuntime(29516): at android.widget.LinearLayout.layoutVertical(LinearLayout.java:1486) 06-29 10:29:02.777: E/AndroidRuntime(29516): at android.widget.LinearLayout.onLayout(LinearLayout.java:1399) 06-29 10:29:02.777: E/AndroidRuntime(29516): at android.view.View.layout(View.java:11278) 06-29 10:29:02.777: E/AndroidRuntime(29516): at android.view.ViewGroup.layout(ViewGroup.java:4224) 06-29 10:29:02.777: E/AndroidRuntime(29516): at android.widget.FrameLayout.onLayout(FrameLayout.java:431) 06-29 10:29:02.777: E/AndroidRuntime(29516): at android.view.View.layout(View.java:11278) 06-29 10:29:02.777: E/AndroidRuntime(29516): at android.view.ViewGroup.layout(ViewGroup.java:4224) 06-29 10:29:02.777: E/AndroidRuntime(29516): at android.view.ViewRootImpl.performTraversals(ViewRootImpl.java:1489) 06-29 10:29:02.777: E/AndroidRuntime(29516): at android.view.ViewRootImpl.handleMessage(ViewRootImpl.java:2442) 06-29 10:29:02.777: E/AndroidRuntime(29516): at android.os.Handler.dispatchMessage(Handler.java:99) 06-29 10:29:02.777: E/AndroidRuntime(29516): at android.os.Looper.loop(Looper.java:137) 06-29 10:29:02.777: E/AndroidRuntime(29516): at android.app.ActivityThread.main(ActivityThread.java:4424) 06-29 10:29:02.777: E/AndroidRuntime(29516): at java.lang.reflect.Method.invokeNative(Native Method) 06-29 10:29:02.777: E/AndroidRuntime(29516): at java.lang.reflect.Method.invoke(Method.java:511) 06-29 10:29:02.777: E/AndroidRuntime(29516): at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:784) 06-29 10:29:02.777: E/AndroidRuntime(29516): at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:551) 06-29 10:29:02.777: E/AndroidRuntime(29516): at dalvik.system.NativeStart.main(Native Method) Code for iChecked (where the id is called) <ImageView android:id="@+id/checkBox" android:padding="2dip" android:layout_width="wrap_content" android:layout_height="wrap_content" android:background="@android:drawable/checkbox_on_background"/>

  • Android 1.6: "android.view.WindowManager$BadTokenException: Unable to add window -- token null is no

    - by Dan Monego
    I'm trying to open a dialog window, but every time I try to open it it throws this exception: E/AndroidRuntime( 206): Uncaught handler: thread main exiting due to uncaught exception E/AndroidRuntime( 206): android.view.WindowManager$BadTokenException: Unable to add window -- token null is not for an application E/AndroidRuntime( 206): at android.view.ViewRoot.setView(ViewRoot.java:460) E/AndroidRuntime( 206): at android.view.WindowManagerImpl.addView(WindowManagerImpl.java:177) E/AndroidRuntime( 206): at android.view.WindowManagerImpl.addView(WindowManagerImpl.java:91) E/AndroidRuntime( 206): at android.app.Dialog.show(Dialog.java:238) E/AndroidRuntime( 206): at android.app.Activity.showDialog(Activity.java:2413) I'm creating it by calling showDialog with the display's id. The onCreateDialog handler logs fine and I can step through it without an issue, but I've attached since it seems like I'm missing something in it: @Override public Dialog onCreateDialog(int id) { Dialog dialog; Context appContext = this.getApplicationContext(); switch(id) { case RENAME_DIALOG_ID: Log.i("Edit", "Creating rename dialog..."); dialog = new Dialog(appContext); dialog.setContentView(R.layout.rename); dialog.setTitle("Rename " + noteName); break; default: dialog = null; break; } return dialog; } Is there something missing from this? Some questions have talked about having this problem when creating a dialog from onCreate, which happen because the activity isn't created yet, but this is coming from a call from a menu object, and the appContext variable seems like it is correctly populated in the debugger.

  • In an iPad SplitView, how do I add a Date Picker control to the Root View?

    - by Dr Dork
    I'm diving into iPhone OS development on the iPad and one of the things I'm playing with is the SplitView template. The template provides a window with a UISplitView view, containing the Root View (on the left of the window) and the Detail View (on the right of the window). The Root View is a subclass of a TableView. Rather than having the entire Root View consist of a TableView, I'd like it to contain a DatePicker view along with the TableView under it. When I go into IB and try and drop a DatePicker into the Root View, it won't let me. It will only let me add a DatePicker view to the Detail View. Why wont IB let me drop a DatePicker view into the Root View? How can I add a DatePicker to the RootView in addition to the TableView? I'm still learning this new platform, so I apologize if these questions are absurd in any way. Thanks so much in advance for your help, I'm going to continue researching these questions right now.

  • Iphone xCode - Navigation Controller on second xib view?

    - by Frames84
    Everything is fine, my navigation controller display's my 'Menu 1' item, but when i click it there appears to be a problem with the: [self.navigationController pushViewController:c animated:YES]; line it doesn't connect to the break point in the myClass file. so I think i've not joined something? but unsure what? my second view with the navigation controller doesn't have direct access to the AppDelegate so can't join it like i see in some tutorials. 1st view is just a button when clicked calls: [self presentModalViewController:mainViewController animated:YES]; my second View 'MainViewController' header looks like: @interface MainViewController :UITableViewController <UITableViewDelegate, UITableViewDataSource> { NSArray *controllers; UINavigationController *navController; } @property (nonatomic, retain) IBOutlet UINavigationController *navControllers; @property (nonatomic, retain) NSArray *controller; Then I have my MainViewController.m @synthesize controllers; @synthesize navController; - (void) viewDidLoad { NSMutableArray *array = [[NSMutaleArray alloc] init]; myClass *c = [[myClass alloc] initWithStyle:UITableViewStylePlain]; c.Title = @"Menu 1"; [array addObject:c]; self.Controllers = array; [array release]; } implemented numberOfRowsInSection and cellForRowAtIndexPath - (void) tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { NSUInteger row = [indexPath row]; myClass *c = [self.controllers objectAtIndex:row]; [self.navigationController pushViewController:c animated:YES]; // doesn't load myClass c // [self.navController pushViewController:c animated:YES]; } Also in interface designer I dragged a Navigation Controller onto my new XIB and changed the Root View Controller class to MainViewController and also connected the File Owner connector to the Navigation Controller to connect the navController Outlet. Thanks for you time.

  • What is the standard convention for defining nested view:viewmodel mapping in MVVM Light

    - by firoso
    so in classic MVVM examples ive seen DataTemplate definitions are used to map up View Models to Views, what is the standard way to do this in MVVM Light framework, and where should the mappings be located? Following are examples of what I'm doing now and what I'm talking about, blendability is important to me! Main Window: <Window xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:d="http://schemas.microsoft.com/expression/blend/2008" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" mc:Ignorable="d" x:Class="STS2Editor.MainWindow" Title="{Binding ApplicationTitle, Mode=OneWay}" DataContext="{Binding RootViewModel, Source={StaticResource Locator}}"> <Window.Resources> <ResourceDictionary> <ResourceDictionary.MergedDictionaries> <ResourceDictionary Source="Skins/ApplicationSkin.xaml" /> <ResourceDictionary Source="Resources/ViewMappings.xaml" /> </ResourceDictionary.MergedDictionaries> </ResourceDictionary> </Window.Resources> <Grid> <ContentControl Content="{Binding ApplicationManagementViewModel}" HorizontalAlignment="Left" VerticalAlignment="Top"/> </Grid> </Window> In the above code, my RootViewModel class has an instance of the class ApplicationManagementViewModel with the same property name: public ApplicationManagementViewModel ApplicationManagementViewModel {get {...} set {...} } I reference the ResourceDictionary "ViewMappings.xaml" to specify how my view model is represented as a view. <ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:local="clr-namespace:STS2Editor.ViewModel"> <DataTemplate DataType="{x:Type local:ApplicationManagementViewModel}"> <local:ApplicationManagementView/> </DataTemplate> </ResourceDictionary> should I be doing things like this using ViewModelLocator? what about collections of view models?

  • Notifying view controller when subview touch events occur.

    - by Nebs
    I have a UIViewController whose view has a custom subview. This custom subview needs to track touch events and report swipe gestures. Currently I put touchesBegan, touchesMoved, touchesEnded and touchesCancelled in the subview class. With some extra logic I am able to get swipe gestures and call my handleRightSwipe and handleLeftSwipe methods. So now when I swipe within the subview it calls its local swipe handling methods. This all works fine. But what I really need is for the handleRightSwipe and handleLeftSwipe methods to be in the view controller. I could leave them in the subview class but then I'd have to bring in all the logic and data as well and that kind of breaks the MVC idea. So my question is is there a clean way to handle this? Essentially I want to keep my touch event methods in the subview so that they only trigger for that specific view. But I also want the view controller to be informed when these touch events (or in this case swipe gestures) occur. Any ideas? Thanks.

  • How to Put Javascript into an ASP.NET MVC View

    - by Maxim Z.
    I'm really new to ASP.NET MVC, and I'm trying to integrate some Javascript into a website I'm making as a test of this technology. My question is this: how can I insert Javascript code into a View? Let's say that I start out with the default ASP.NET MVC template. In terms of Views, this creates a Master page, a "Home" View, and an "About" view. The "Home" View, called Index.aspx, looks like this: <%@ Page Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage" %> <asp:Content ID="indexTitle" ContentPlaceHolderID="TitleContent" runat="server"> Home Page </asp:Content> <asp:Content ID="indexContent" ContentPlaceHolderID="MainContent" runat="server"> <h2><%= Html.Encode(ViewData["Message"]) %></h2> <p> To learn more about ASP.NET MVC visit <a href="http://asp.net/mvc" title="ASP.NET MVC Website">http://asp.net/mvc</a>. </p> <p>Welcome to this testing site!</p> </asp:Content> Adding a <script> tag here didn't work. Where and how should I do it? P.S.: I have a feeling I'm missing something very basic... Thanks in advance!

  • iphone app scroll view is horizontal but i want it vertical - how do i change this?

    - by Billy Jones
    Hi Folks, Got this code for a viewscroller from the apple developers site. @synthesize scrollView1, scrollView2; const CGFloat kScrollObjHeight = 467.0; const CGFloat kScrollObjWidth = 320.0; const NSUInteger kNumImages = 6; (void)layoutScrollImages { UIImageView *view = nil; NSArray *subviews = [scrollView1 subviews]; // reposition all image subviews in a horizontal serial fashion CGFloat curXLoc = 0; for (view in subviews) { if ([view isKindOfClass:[UIImageView class]] && view.tag 0) { CGRect frame = view.frame; frame.origin = CGPointMake(curXLoc, 0); view.frame = frame; curXLoc += (kScrollObjWidth); } } // set the content size so it can be scrollable [scrollView1 setContentSize:CGSizeMake((kNumImages * kScrollObjWidth), [scrollView1 bounds].size.height)]; } it works brilliantly the images are rotated by pulling them left or right. but I want to pull the images up and down to change them. Can anyone help me out with this? this part in the code looks as if it controls the direction but i'm not sure how to change it. // reposition all image subviews in a horizontal serial fashion CGFloat curXLoc = 0; for (view in subviews) { if ([view isKindOfClass:[UIImageView class]] && view.tag 0) { CGRect frame = view.frame; frame.origin = CGPointMake(curXLoc, 0); view.frame = frame; curXLoc += (kScrollObjWidth); } } Any help most appreciated, thanks!

  • Presenting UINavigationController modally -- problem setting up tool and nav bar items in root view controller viewDidLoad

    - by Bogatyr
    In my iOS app I'm creating and presenting a UINavigationController modally like so: MyViewController *myvc = [[[MyViewController alloc] initWithNibName:@"MyViewController" bundle:nil] autorelease]; UINavigationController *navVC = [[[UINavigationController alloc] initWithRootViewController:myvc] autorelease]; [self presentModalViewController:navVC animated:YES]; In the MyViewController viewDidLoad I'm creating and setting toolbar items for the navigation controller's toolbar, like so: self.navigationController.toolbar.items = [NSArray arrayWithObjects:(items...), nil]; the problem I'm having is that the items don't show up. If instead I call a method from MyViewController's viewDidLoad method that adds the toolbar items via performSelector:withObject:afterDelay:0, then it works perfectly. So there's obviously some race condition going on here with the initial presentation of the UINavigationController, initialization of its toolbar/navbar, and the initialization of the nav bar's specified initial root view controller. I verified in the debugger that the root view controller's viewDidLoad is called after the UINavigationController's viewDidLoad method. In fact, the root view controller's viewDidLoad method is not called until presentModalViewController: is called, and the UINavigationController's viewDidLoad is called within initWithRootViewController, so doesn't that imply that the UINavigationController object should be "all ready to go", including its nav bar and toolbars? I thought at first that the navigation controller's toolbar object may not exist yet at MyViewController's viewDidLoad time, but it clearly does. At least, NSLog shows that it is not nil during MyViewController's viewDidLoad method. In fact, the UINavigationController's toolbar object is identical at both times: in the root view controller's viewDidLoad, and in the "setupToolbar" method that I called with performSelector:withObject:afterDelay, so it's not getting "re-initialized" somehow. So, what's going on here? Why aren't my toolbar modifications "sticking" in MyViewController's viewDidLoad, and why does performing them in the next iteration of the runloop (performSelector:withObject:afterDelay:0) make it work? What is the "right" way of setting up initial navbar / toolbar items in code from the rootViewController of the UINavigationController?

  • WPF Usercontrol interaction with parent view / viewmodel

    - by obaylis
    Hi I have a mainView window which has its dataContext set to it's own viewModel. On that viewModel is a DateTime property which in turn is bound to a datepicker on my main view using 2 way binding. <toolkit:DatePicker DateSelected="{Binding mainDateTimeProperty, Mode=TwoWay}" /> This is all fine so far. On the change of my datetime property I create a list which is then bound to a datagrid elsewhere on the mainview. This all works fine. My question is to do with a usercontrol I want to add to the main view. I want this usercontrol to be self contained so have created it with it's own viewmodel but it does also need access to mainDateTimeProperty I thought that best way to go would be to create a dependencyProperty on the usercontrol and when I create my control in the main view I bind the dp to the datetime as follows. <uc:MyNewUserControl DateProperty="{Binding mainDateTimeProperty}" /> Trouble is how do I have the usercontrol maintain datacontext with it's viewmodel and yet still have the dependency property bound to a property on the main view model? Hope this is clear. Can post some more code if necessary. Looking for a best practice approach if possible. Thanks very much for any advice.

  • Strange UIKit bug, table view row stays selected

    - by Can Berk Güder
    I'm facing what appears to be a UIKit bug, and it takes the combination of two less commonly used features to reproduce it, so please bear with me here. I have quite the common view hierarchy: UITabBarController -> UINavigationController -> UITableViewController and the table view controller pushes another table view controller onto the navigation controller's stack when a row is selected. There's absolutely nothing special or fancy in the code here. However, the second UITableViewController, the "detail view controller" if you will, does two things: It sets hidesBottomBarWhenPushed to YES in its init method, so the tab bar is hidden when this controller is pushed: - (id)initWithStyle:(UITableViewStyle)style { if(self = [super initWithStyle:style]) { self.hidesBottomBarWhenPushed = YES; } return self; } It calls setToolbarHidden:NO animated:YES and setToolbarHidden:YES animated:YES on self.navigationController in viewWillAppear: and viewWillDisappear: respectively, causing the UIToolbar provided by UINavigationController to be displayed and hidden with animations: - (void)viewWillAppear:(BOOL)animated { [super viewWillAppear:animated]; [self.navigationController setToolbarHidden:NO animated:YES]; } - (void)viewWillDisappear:(BOOL)animated { [super viewWillDisappear:animated]; [self.navigationController setToolbarHidden:YES animated:YES]; } Now, if the second UITableViewController was pushed by selecting the row at the bottom of the screen (it doesn't have to be the last row) in the first controller, this row does not automatically get deselected when the user immediately or eventually returns to the first controller. Further, the row cannot be deselected by calling deselectRowAtIndexPath:animated: on self.tableView in viewWillAppear: or viewDidAppear: in the first controller. I'm guessing this is a bug in UITableViewController's drawing code which of course only draws visible rows, but unfortunately fails to determine correctly if the bottommost row will be visible in this case. I failed to find anything on this on Google or OpenRadar, and was wondering if anyone else on SO had this problem or knew a solution/workaround.

  • ASP.NET Ajax - Asynch request has separate session???

    - by Marcus King
    We are writing a search application that saves the search criteria to session state and executes the search inside of an asp.net updatepanel. Sometimes when we execute multiple searches successively the 2nd or 3rd search will sometimes return results from the first set of search criteria. Example: our first search we do a look up on "John Smith" - John Smith results are displayed. The second search we do a look up on "Bob Jones" - John Smith results are displayed. We save all of the search criteria in session state as I said, and read it from session state inside of the ajax request to format the DB query. When we put break points in VS everything behaves as normal, but without them we get the original search criteria and results. My guess is because they are saved in session, that the ajax request somehow gets its own session and saves the criteria to that, and then retrieves the criteria from that session every time, but the non-async stuff is able to see when the criteria is modified and saves the changes to state accordingly, but because they are from two different sessions there is a disparity in what is saved and read. EDIT::: To elaborate more, there was a suggestion of appending the search criteria to the query string which normally is good practice and I agree thats how it should be but following our requirements I don't see it as being viable. They want it so the user fills out the input controls hits search and there is no page reload, the only thing they see is a progress indicator on the page, and they still have the ability to navigate and use other features on the current page. If I were to add criteria to the query string I would have to do another request causing the whole page to load, which depending on the search criteria can take a really long time. This is why we are using an ajax call to perform the search and why we aren't causing another full page request..... I hope this clarifies the situation.

  • Data Transfer Objects VS Domain/ActiveRecord Entities in the View in RoR

    - by leypascua
    I'm coming from a .NET background, where it is a practice to not bind domain/entity models directly to the view in not-so-basic CRUD-ish applications where the view does not directly project entity fields as-is. I'm wondering what's the practice in RoR, where the default persistence mechanism is ActiveRecord. I would assert that presentation-related info should not be leaked to the entities, not sure though if this is how real RoR heads would do it. If DTOs/model per view is the approach, how will you do it in Rails? Your thoughts? EDIT: Some examples: - A view shows a list of invoices, with the number of unique items in one column. - A list of credit card accounts, where possibly fraudulent transactions were executed. For that, the UI needs to show this row in red. For both scenarios, The lists don't show all of the fields of the entities, just a few to show in the list (like invoice #, transaction date, name of the account, the amount of the transaction) For the invoice example, The invoice entity doesn't have a field "No. of line items" mapped on it. The database has not been denormalized for perf reasons and it will be computed during query time using aggregate functions. For the credit card accounts example, surely the card transaction entity doesn't have a "Show-in-red" or "IsFraudulent" invariant. Yes it may be a business rule, but for this example, that is a presentation concern, so I would like to keep it out of my domain model.

  • Adding a UITapGestureRecognizer to a view then removing seems to short circuit button events

    - by heymon
    In the code below I am popping up a ImageView as the result of a users touchUpInside on a simple info button. There are other buttons on the view. To dismiss the info I added a UITapGestureRecognizer to my controllers view, and hide the view when the tap is detected. If I don't remove the tapGestureRecognizer, the action is called every time some. Even when I do remove the gesture action, no bottons receive touchUpInside events once this gesture recognizer is added. Why? Code from my MainViewController (void) dismissInfo: (UITapGestureRecognizer *)gesture { [kInfoView setHidden: YES]; [gesture removeTarget: self action: NULL]; } (IBAction) displayInfo { CGRect startFrame = CGRectMake(725, 25, 0, 0), origFrame; CGFloat yCenter = [kInfoView frame].size.height/2 + 200; CGPoint startCenter = CGPointMake(724, 25), displayCenter = CGPointMake(384, yCenter); UITapGestureRecognizer *g = [[UITapGestureRecognizer alloc] initWithTarget: self action: @selector(dismissInfo:)]; [self.view addGestureRecognizer: g]; origFrame = [kInfoView frame]; [kInfoView setCenter: startCenter]; [kInfoView setHidden: NO]; [kInfoView setFrame: startFrame]; [UIView beginAnimations: @"info" context: nil]; [UIView setAnimationDuration: .5]; [UIView setAnimationDelegate: self]; [kInfoView setFrame: origFrame]; [kInfoView setCenter: displayCenter]; [UIView commitAnimations]; }

  • MVC View Model Intellisense / Compile error

    - by Marty Trenouth
    I have one Library with my ORM and am working with a MVC Application. I have a problem where the pages won't compile because the Views can't see the Model's properties (which are inherited from lower level base classes). They system throws a compile error saying that 'object' does not contain a definition for 'ID' and no extension method 'ID' accepting a first argument of type 'object' could be found (are you missing a using directive or an assembly reference?) implying that the View is not seeing the model. In the Controller I have full access to the Model and have check the Inherits from portion of the view to validate the correct type is being passed. Controller: return View(new TeraViral_Blog()); View: <%@ Page Title="" Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage<com.models.TeraViral_Blog>" %> <asp:Content ID="Content1" ContentPlaceHolderID="TitleContent" runat="server"> Index2 </asp:Content> <asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server"> <h2>Index2</h2> <fieldset> <legend>Fields</legend> <p> ID: <%= Html.Encode(Model.ID) %> </p> </fieldset> </asp:Content>

  • Java design: too many getters

    - by dege
    After writing a few lesser programs when learning Java the way I've designed the programs is with Model-View-Control. With using MVC I have a plethora of getter methods in the model for the view to use. It feels that while I gain on using MVC, for every new value added I have to add two new methods in the model which quickly get all cluttered with getter & setters. So I was thinking, maybe I should use the notifyObserver method that takes an argument. But wouldn't feel very smart to send every value by itself either so I figured, maybe if I send a kind of container with all the values, preferably only those that actually changed. What this would accomplish would be that instead of having a whole lot of getter methods I could just have one method in the model which put all relevant values in the container. Then in the view I would have a method called from the update which extracted the values from the container and assigning them to the correct fields. I have two questions concerning this. First: is this actually a viable way to do this. Would you recommend me doing something along these lines? Secondly: if I do use this plan and I don't want to keep sending fields that didn't actually change. How would I handle that without having to have if statements to check if the value is not null for every single value?

  • Custom view with nib as subview doesn't seem to be loading

    - by Ben Collins
    I've created a custom view that loads its content from a nib, like this: /* PricingDataView.h */ #import <UIKit/UIKIt.h> @interface PricingDataView : UIView { UIView *contentView; } @property (nonatomic, retain) IBOutlet UIView *contentView; @end /* PricingDataView.m */ #import "PricingDataView.h" @implementation PricingDataView @synthesize contentView; - (id)initWithFrame:(CGRect)frame { if ((self = [super initWithFrame:frame])) { [[NSBundle mainBundle] loadNibNamed:@"PricingDataView" owner:self options:nil]; [contentView setFrame:frame]; [self addSubview:contentView]; } return self; } /* ... */ In the nib file I set PricingDataView as the type of the File's Owner, and connected the contentView outlet in IB. I placed a regular UIView from the Interface Library onto the full-sized view shown to the user, and then changed it's class name to PricingDataView. It all builds, but at runtime, nothing is rendered where my custom view is supposed to be. I put breakpoints in PricingDataView.initWithFrame, but they don't hit, so I know I'm missing something that would cause the view to be initialized. What I'm curious about is that int the process of loading my other views from nibs, all the initialization happens for me, but not with this one. Why?
