  • Neither IE or Firefox respects the control values that are output

    - by Luke Rohde
    I'm writing a survey designer asp.net mvc. It has buttons to move questions up and down. The buttons post the whole form back and the affected questions are swapped on the server. When the form returns the only thing that is changed are the values for each survey question. Both firefox and IE seem to ignore this change. Nothing is persisted to the database (until save) and url doesn't change so the post just returns the same view but I've stepped through my code to ensure the sequence of values being rendered in the view reflects the swap which is ok. However "view - source" doesn't show the change suggesting caching issue (maybe auto complete). I've tried autocomplete="off" in my form. Response.Cache.SetNoStore(); in my global.asax [System.Web.Mvc.OutputCache(NoStore = true, Duration = 0, VaryByParam = "*")] before my controller and the following in my page header NOTHING!!! This must be real common. Anyone got a clue?

  • WPF ComboBox SelectedItem - change to previous value

    - by Taylor
    Hello, I have a ComboBox that has the SelectedItem bound to the ViewModel. <ComboBox SelectedItem="{Binding SelItem, Mode=TwoWay}" ItemsSource="{Binding MyItems}"> When the user selects a new Item in the View ComboBox, I want to display a prompt and verify that they want to make the change. In the SetItem Property setter in the View Model, I display a Dialog to confirm the selection. When they say yes, it works fine. My problem is, when the user clicks on "No" I am not sure who to get the ComboBox to revert back to the previous value. The Property in the ViewModel has the correct older value, however in the View the ComboBox displays the newly Selected Value. I want the user to select an item, confirm they want to go ahead with it, and if they decide not to, I want the ComboBox to revert back to the previous item. How can I accomplish this? Thanks!

  • Modifying generator.yml views in Symfony

    - by Alex Ciminian
    Hey! I'm currently working on a web app written in Symfony. I'm supposed to add an "export to CSV" feature in the backend/administration part of the app for some modules. In the list view, there should be an "Export" button which should provide the user with a csv file of the elements that are displayed (considering filtering criteria). I've created a method in the actions class of the module that takes a comma separated list of ids and generates the CSV, but I'm not really sure how to add the link to it in the view. The problem is that the view doesn't exist anywhere, it's generated on the fly from the data in the generator.yml configuration file. I've posted the relevant part of the file below. list: display: [=name, indemn, _status, _participants, _approved_, created_at] title: Lista actiuni object_actions: _edit: ~ _delete: ~ filters: [name, county_id, _status_filter, activity_id] fields: name: name: Nume Actiune indemn: name: Îndemn la actiune description: name: Descriere approved_: name: Operatiune created_at: name: Creata la status: name: Status Actiune I'm new to Symfony, so any help would be appreciated :). Thanks, Alex

  • Rails Custom Plugin/Gem with Partials

    - by Jason
    I am writing a gem which provides helpers for views. The HTML I want to insert via the helper is complex enough that I'd rather write it in a _partial.html.erb file. How do I get the gem's view path include in the application's load_path? Note: the only gem I've found that does something like this is Devise. When a view cannot be found, Rails prints the load path which (on my machine) looks like: Missing partial sortable_nested_set/tree with {:handlers=>[:erb, :rjs, :builder, :rhtml, :rxml], :formats=>[:html], :locale=>[:en, :en]} in view paths "/home/jason/VirtualRestaurant3/app/views", "/home/jason/.rvm/gems/ruby-1.9.2-preview3/gems/devise-1.1.rc0/app/views" How does Devise do it? My gem: http://github.com/jrmurad/SortableNestedSet Devise gem: +http://+github.com/plataformatec/devise

  • Iphone UIView implementation

    - by Joo Park
    How does one code this scenerio in iphone sdk? In an expense app, when you want to add an expense, this view comes up. After selecting "Clothing," another view slides up with a UIPickerView control that has a "done" button which will dismiss the UIPickerView. Below is a screen shot after hitting "Clothing." I'm trying to figure out how one would slide up the UIPickerView half way up the screen with a "done" button on top of the "New Expense" view? thank you in advance!

  • Position a UIView at the middle of a UITableView with CGRectZero frame

    - by Thomas Joulin
    Hi, I have a UITableViewController view a UITableView that I alloc/init with a frame of CGRectZero : self.tableView = [[UITableView alloc] initWithFrame:CGRectZero style:UITableViewStyleGrouped]; I want to add a view at the middle of the tableView (a loading view with a UIActivityIndicatorView and a UILabel), but I don't know how to position it, since I don't know the tableView frame. x = (self.tableview.frame.size.width - loadingView.frame.size.width) / 2.0; y = (self.tableview.frame.size.height - loadingView.frame.size.height) / 2.0; [loadingView setCenter:CGPointMake(x, y)]; I did init my tableView with CGRectZero frame so it can take the whole place available on screen (which it did), but I thought its frame would update or something. Any ideas ? Thanks !

  • Adding Listeners at runtime? - Java MVC

    - by Halo
    My model in my MVC pattern, generates components at runtime and gives them to the View to be displayed on the screen through update() method (you know, model is the observable and the view is the observer). But I also need to add listeners to these components, and the controller has the listener methods (because they say the MVC pattern is like this) and it's not involved in this update process. So I can't add the listeners at runtime, but only in the controller's constructor at startup. I've got an idea, that is making the controller the observer and then giving the data to the view, as well as adding the listeners. Do you think this would be OK?

  • problem with adding tool bar to UITableView

    - by chnet
    I'm writing a Navigation-Based iPhone app, and I'd like to have a UIToolBar docked at the bottom of my screen, with a UITableView scrolling between the tool bar and the navigation bar. I used [[self navigationController] setToolbarHidden:NO] and - (void)setToolbarItems:(NSArray *)toolbarItems animated:(BOOL)animated to set the UIToolBar. UIToolBar correctly shows in current view. If I drill down into a detail view using the button on navigation bar, i cannot return back to previous view. Before I add the tool bar, it can return back. I am wondering is there anything else should be noted when use UIToolbar?

  • How to SET ARITHABORT ON for connections in Linq To SQL

    - by Laurence
    By default, the SQL connection option ARITHABORT is OFF for OLEDB connections, which I assume Linq To SQL is using. However I need it to be ON. The reason is that my DB contains some indexed views, and any insert/update/delete operations against tables that are part of an indexed view fail if the connection does not have ARITHABORT ON. Even selects against the indexed view itself fail if the WITH(NOEXPAND) hint is used (which you have to use in SQL Standard Edition to get the performance benefit of the indexed view). Is there somewhere in the data context I can specify I want this option ON? Or somewhere in code I can do it?? I have managed a clumsy workaround, but I don't like it .... I have to create a stored procedure for every select/insert/update/delete operation, and in this proc first run SET ARITHABORT ON, then exec another proc which contains the actual select/insert/update/delete. In other words the first proc is just a wrapper for the second. It doesn't work to just put SET ARITHABORT ON above the select/insert/update/delete code.

  • Android - Notification bar height from a service

    - by Vitaliy
    Hi, The application I'm working on is a service which runs in the background in android. The problem is that I need to determine the height of the notification bar for some functionality of the service. I found a number of solutions for this, for regular activities - a view inside an activity can determine its own height without the notification bar, based on checking its actual view size from its onSizeChanged event, after it is already drawn. However, this is not applicable to a service which has no physical view drawn. I would really appreciate any ideas on getting the size of the notification bar at a system level, perhaps? Thanks so much! Vitaliy

  • Anything wrong with this code?

    - by ct2k7
    I am using this to determine which view to go to next, from the result as input from UITableView. The following code isn't working, but I think it should be! Do you see anything wrong with it? NSString *option = [menuArray objectAtIndex:indexPath.row]; if (option == @"New Transaction"){ NTItems *nTItemsController = [[NTItems alloc] initWithNibName:@"NTItems" bundle:nil]; // Pass the selected object to the new view controller. [self.navigationController pushViewController:nTItemsController animated:YES]; [NTItems release];} else if (option == @"Previous Transactions"){} else if (option == @"Reprint a reciept"){} else if (option == @"Settings"){} else if (option == @"Logout"){ LoginViewController *nTItemsController = [[LoginViewController alloc] initWithNibName:@"LoginViewController" bundle:nil]; // Pass the selected object to the new view controller. [self.navigationController pushViewController:nTItemsController animated:YES]; [LoginViewController release]; }

  • Add UIView behind UITableView in UITableViewController code

    - by Drew C
    I would like to use a fixed image as the background in a simple grouped table view in my iPhone program. Unfortunately, no matter what I do, the background is always solid white. I have followed several supposed solutions on this site and others to no avail. Here is the relavant code in the viewDidLoad method of the table view controller class (note, this code uses a solid blue color rather than an image for simplicity's sake): self.tableView.opaque = NO; self.tableView.backgroundColor = [UIColor clearColor]; UIView *backgroundView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 320, 480)]; backgroundView.backgroundColor = [UIColor blueColor]; [self.tableView.window addSubview:backgroundView]; [backgroundView release]; I suspect that I am not positioning the backgroundView view in the right place. I have tried sendToBack:, bringToFront:, and others but I always just get a white background. Is it possible to do this from within the UITableViewController? Must I use Interface Builder?

  • Resize Ext.form.ComboBox to fit its content

    - by ITRushn
    There are quite few solutions on Ext forums, but I wasn’t able to get any of them work. It seems I am missing something minor. I need to resize combobox to fit its content when it’s first created. I do not need to worry about resizing it when content is changing. Is there any working examples using Extjs 3.2? Current Code: var store = new Ext.data.ArrayStore({ fields: ['view', 'value', 'defaultselect'], data: Ext.configdata.dataCP }); comboCPU = new Ext.form.ComboBox({ tpl: '<tpl for="."><div class="x-combo-list-item"><b>{view}</b><br /></div></tpl>', store: store, displayField: 'view', width: 600, typeAhead: true, forceSelection: true, mode: 'local', triggerAction: 'all', editable: false, emptyText: 'empty text', selectOnFocus: true, listeners: { select: AdjustPrice, change: AdjustPrice, beforeselect: function (combo, record, index) { return ('false' == record.data.disabled); } }, applyTo: 'confelement' }); I've also tried removing width: 600 and replacing it with minListWidth: 600 but that result following and didnt fix the issue.

  • iPhone: Using plist to populate a grouped table

    - by Jack Griffiths
    Hi there, I was wanting to use a plist to populate my grouped table. I've had a look at the DrillDownSave sample project, and I'm still none-the-wiser. Although, I did learn that I could store hierarchies and suchlike in there. So here's the questions: How can I use my plist to add new items to my grouped table? I'm currently feeding the table with an array, and I've noticed that an array isn't going to be the best thing for me. When a user taps on an item in the plist, how can I push the view to the corresponding item? In other words, how can I push the view based on the selected row (which was generated by the plist) to it's next "view"? If that makes any sense, please reply. Thanks, Jack.

  • Dynamically loading hi-res images into UIScrollView

    - by Jeff
    I've been looking into creating a gallery mode in my application. The functionality will be identical to the built in Photos App. Here's the flow: 1. You touch on a thumbnail and ... 2. a modal view displays a large detail version of the image 3. You have the ability to scroll horizontally through all the images in the gallery while in this modal view I'm stuck on step 3. How do I dynamically load hi res images into a scroll view? I understand I need to set the contentSize for the the scrollView but how do I do that when I've only selected and loaded one image? What delegate methods do I need to implement and what does the heavy lifting look like? Thanks in advance!

  • Drupal: Content in blocks from node_reference fields?

    - by Marco
    After only a few weeks of working with Drupal I've come up with a recurring problem, which I don't really have an optimal solution to, so I'm hoping that someone here might be able to give some best practice pointers. What I have is a region inside my node.tpl.php, which is populated with blocks that display content from two different CCK fields of the type node_reference. This works fine when displaying a single node. The problem appears when I need to use a view. For example, lets say I have a news listing, and a single news item view. When I display the single news item I can use the news node node_reference field to reference whatever material I would like to have in my sidebar, but when on the news listing view I would like to reference nodes separately. What would be the best practice to solve this? I'm having a few ideas, but none seem like the logical choice, how would you do?

  • Limit to area that receives touch events

    - by Typeoneerror
    Is there's a bounding box on an application that receives touch events? I created a few sample round rect buttons and placed them in different places in my view. The ones in the center of the view receive touch events (and show the highlighted blue color) but if I place a button near the edges of the view, only parts of them are clickable in the simulator. Is this because of Apples style guidelines? I placed a button exactly where a UITabNavigationItem would appear and only the bottom half of it is clickable.

  • NSAlert pops up for 3 times

    - by Marco
    Hello community i have a big problem. i implemented an NSAlert in the viewDidLoad() of my app: UIAlertView *alert = [[UIAlertView alloc] initWithTitle:title message:alertMessage delegate:self cancelButtonTitle:ok otherButtonTitles:nil]; But the Alert pops up for 3 times, and then i can klick on it. Could it be that the viewDidLoad() starts for 3 times? This is the viewDidLoad in the rootViewController, that manages the views: - (void)viewDidLoad { Kundenkarte *kartenAnsicht = [[Kundenkarte alloc] initWithNibName:@"Kundenkarte" bundle:nil]; kartenAnsicht.rootViewController = self; kartenAnsicht.viewDidLoad; self.map = kartenAnsicht; [self.view addSubview:kartenAnsicht.view]; [kartenAnsicht release]; // [super viewDidLoad]; } kartenAnsicht is the view where the problem is. I hope someone could help me because my ideas are over!

  • Android VideoView plays 2 videos at the same time

    I ma trying to play a videoview on top of another video view. the first video view is paused, while the second is playing. It appears to work but no second video appears on he screen (though I hear the audio and see the controls that would normally appear on top). I am assuming this is some sort of Zorder issue. Any thoughts. By the way, I have no problem displaying other views on top of the main video view and having the video fill the background.

  • logic of button to be disabled or not in mvc

    - by rod
    Hi All, Here's an excerpt from a book I'm reading about application design with MVC: Ideally, the view is so simple and logic-free as to need virtually no testing. Users (and developers before users) can reasonably test the view by simply looking at the pixels on the screen. Anything else beyond pure graphical rendering should ideally be taken out of the view and placed in the controller and model. This includes, for example, the logic that determines whether a certain button should be enabled or grayed out at some point. what does the bold statement mean to you? what would this look like? thanks, rod.

  • Tiling solution for the iPhone that can handle infinite # of tiles

    - by rickharrison
    I have been looking at ways to implement a tiling solution on the iPhone/iPad similar to something like Google Maps. I have looked at examples of how to implement a CATiledLayer into a view that is inside a UIScrollView. Then when you scroll the view, the tiles request the new data to be shown. However, this seems to work when you have a finite view size (ie: 3000x3000). However, how could I work this into a tiling solution for much larger sizes. Basically, I want to be able to show data as needed for tiles as large as I can. Can I somehow use CATiledLayer to do this? Any direction would be greatly appreciated.
