  • HTML5 Video Element on iPad doesn't fire onclick?

    - by bhups
    I am using the video element in my HTML as following:<div id="container" style="background:black; overflow:hidden;width:320px;height:240px" <video style="background:black;display:block" id="vdo" height="240px" width="320px" src="http://mydomain/vid.mp4"</video</div And in javascript I am doing this:var video=document.getElementById('vdo'); var container=document.getElementById('container'); video.addEventListener('click', function(e) { e.preventDefault(); console.log("clicked"); }, false); container.addEventListener('click', function(e) { e.preventDefault(); console.log("clicked"); }, false); On desktop safari/chrome everything is working fine. I can see two "clicked" in the console. But on ipad there is nothing. First I tried with iOS versin 3.2, then I updated it to the latest one 4.2.1 without any success.I found a similar question HTML5 Video Element on iPad doesn't fire onclick or touchstart events? where it suggests not to use controls in video tag and I am not using it.

  • How to Prevent PostBack Event Handler from Firing

    - by user331744
    I have a custom class (ServerSideValidator.vb) that validates user input on server side (it doesn't use any of the .NET built in validators, therefore Page.Validate() is not an option for me). I am calling the Validate() method on page.IsPostback event and the class performs without any problem My issue is, when validation fails (returns false), I want to stop the postback event handler from firing, but load the page along with all the controls and user-input values in them. If I do, Response.End(), the page comes up blank. I can programmatically instruct the page to go to the previous page (original form before postback), but it loses all user-inputs. I thought of creating a global boolean variable in the page code behind file and check the value before performing any postback method, but this approach takes away from my plan to provide all functionalities inside the class itself. The page object is being referenced to ServerSideValidator. Seems like all the postback related properties/variables I come across inside Page class are 'Readonly' and I can't assign value(s) to control/prevent postback event from firing. Any idiea on how I can accomplish this? Please let me know if you need further details

  • Problem with derived ControlTemplates in WPF

    - by Frank Fella
    The following xaml code works: <Window x:Class="DerivedTemplateBug.Window1" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:local="clr-namespace:DerivedTemplateBug" Title="Window1" Height="300" Width="300"> <Button> <Button.Template> <ControlTemplate> <Border BorderBrush="Black" BorderThickness="2"> <TextBlock>Testing!</TextBlock> </Border> </ControlTemplate> </Button.Template> </Button> </Window> Now, if you define the following data template: using System.Windows.Controls; namespace DerivedTemplateBug { public class DerivedTemplate : ControlTemplate { } } And then swap the ControlTemplate for the derived class: <Window x:Class="DerivedTemplateBug.Window1" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:local="clr-namespace:DerivedTemplateBug" Title="Window1" Height="300" Width="300"> <Button> <Button.Template> <local:DerivedTemplate> <Border BorderBrush="Black" BorderThickness="2"> <TextBlock>Testing!</TextBlock> </Border> </local:DerivedTemplate> </Button.Template> </Button> </Window> You get the following error: Invalid ContentPropertyAttribute on type 'DerivedTemplateBug.DerivedTemplate', property 'Content' not found. Can anyone tell me why this is the case?

  • Where to translate message strings - in the view or in the model?

    - by GrGr
    We have a multilingual (PHP) application and use gettext for i18n. There are a few classes in the backend/model that return messages or message formats for printf(). We use xgettext to extract the strings that we want to translate. We apply the gettext function T_() in the frontend/view - this seems to be where it belongs. So far we kept the backend clean from T_() calls, this way we can also unit-test messages. So in the frontend we have something like echo T_($mymodel->getMessage()); or printf(T_($mymodel->getMessageFormat()), $mymodel->getValue()); This makes it impossible to apply xgettext to extract the strings, unless we put some dummy T_("my message %s to translate") call in the MyModel class. So this leads to the more general question: Do you apply translation in the backend classes, resp. where do you apply translation and how do you keep track of the strings which you have to translate? (I am aware of Question: poedit workaround for dynamic gettext.)

  • What's the proper approach for writing multi-path "story" flows?

    - by Basiclife
    Hi, I wonder if you can help me. I'm writing a game (2d) which allows players to take multiple routes, some of which branch/merge - perhaps even loop. Each section of the game will decide which section is loaded next. I'm calling each section an IStoryElement - And I'm wondering how best to link these elements up in a way that is easily changed/configured and at the same time, graphable I'm going to have an engine/factory assembly which will load the appropriate StoryElement(s) based on various config options. I initially planned to give each StoryElement a NextElement() As IStoryElement property and a Completed() event. When the vent fires, the engine reads the NextElement property to find the next StoryElement. The downside to this is that if I ever wanted to graph all the routes through the game, I would be unable to - I couldn't determine all possible targets for each StoryElement. I considered a couple of other solutions but they all feel a little clunky - eg Do I need an additional layer of abstraction? ie StoryElementPlayers or similar - Each one would be responsible for stringing together multiple StoryElement perhaps a Series and a ChoicePlayer with each responsible for graphing its own StoryElement - But this will just move the problem up a layer. In short, I need some way of emulating a simple but dynamic workflow (but I'd rather not actually use WWF). Is there a pattern for something this simple? All the ones I've managed to find relate to more advanced control flow (parallel processing, etc.)

  • A rectangle drawn with DrawingContext.DrawRectangle blocks mouse

    - by dharmatech
    The WPF program below puts up a window which looks like this: Mouse-movement outside the black square causes the window title to be updated with the mouse's position. The updating stops when the mouse enters the square. I'd like for MouseMove to continue to trigger even when the mouse is over the square. Is there a way to do this? using System.Windows; using System.Windows.Controls; using System.Windows.Media; namespace Wpf_Particle_Demo { class DrawingVisualElement : FrameworkElement { public DrawingVisual visual; public DrawingVisualElement() { visual = new DrawingVisual(); } protected override int VisualChildrenCount { get { return 1; } } protected override Visual GetVisualChild(int index) { return visual; } } public partial class MainWindow : Window { public MainWindow() { InitializeComponent(); var canvas = new Canvas(); Content = canvas; var element = new DrawingVisualElement(); canvas.Children.Add(element); CompositionTarget.Rendering += (s, e) => { using (var dc = element.visual.RenderOpen()) dc.DrawRectangle(Brushes.Black, null, new Rect(0, 0, 50, 50)); }; MouseMove += (s, e) => Title = e.GetPosition(canvas).ToString(); } } }

  • I read 3 pages of a JQuery book and here's my reaction and question

    - by George
    My jQuery reaction to the language's flexible "selectors" is probably rooted in this experience: I once had managed a project where a developer constructed a web page that was used by users to provide very flexible search parameters for a search screen using dynamic sql string building based on the user's specified search parameter. The resulting queries were usually very complicated and involved joins to many tables. One of the options that the user had was to choose from one of 3 an options. Depending on the user's choice for this option, the resulting SQL would need to query a different set of database columns. For example, if choice option "A" were selected, the resulting database columns queried would be prefixed with "A_"; if option "B" were selected, he resulting database columns queried would be prefixed with "B_" and so on. The developer choice to write all the complete SQL assuming that the user selected, for example, option "A" and therefore first constructed SQLs of this type: SQL = "SELECT A_COL1, A_COL2, A_COL3 FROM TABLE ..." and then after constructing one of a million possible variations on the Query From Hell, did something like this: If UserOption = "B" then SQL = SQL.Replace("A_","B_") 'replace everywhere End if He insisted that this was the easiest was to code it, and while I understood that, I was concerned about maintenance of this code. You see, this worked for a while, but as the search options grew and the database columns evolved, the various "REPLACE small substring" with another small substring had unexpected consequences when applied to an evolving database and new search options. My feeling is that code should be written as much as possible such that you can add to it without fear of breaking what is already there. I feel a better approach, though a bit more work, would have been to write a function to return the appropriate target column based on a common set name and the user selected option. OK, so what does this have to do with jQuery selectors? Are the ultra flexible JQuery selectors kind of like perform a "replace all" on a SQL string? Handy as hell but potentially creating a maintenance nightmare?

  • Flex 3 (Action Script): How to access a function from a loaded swf-file ?

    - by Trantec
    Hi, i load in ActionScript a swf file. So far no Problem, but I didn't found a way to access one of it's functions, the best thing would be if I could access the main function in the mxml part of the swf. Here is the code of the main-mxml file that belongs to the swf that should load and access another swf: <?xml version="1.0" encoding="utf-8"?> <mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute" initialize="basket();"> <mx:Script> <![CDATA[ import mx.controls.SWFLoader; private function basket(): void { var swfLoader: SWFLoader = new SWFLoader(); swfLoader.addEventListener( Event.COMPLETE, handleSWFLoaded ); try { swfLoader.load( "../../data/InternalSWF.swf" ); } catch (error: Error) { trace( "Couldn't load file !" ); } } private function handleSWFLoaded( event: Event ): void { var swfApp:* = event.target.content; // This both ways don't work... //if (swfApp.hasOwnProperty("initApp")) { // var initApp:Function = (swfApp["initApp"] as Function); // initApp(); //} // swfApp.initApp(); } ]]> </mx:Script> <mx:Text id="output" width="100%" textAlign="center" /> </mx:Application> The if-Statement "if (swfApp.hasOwnProperty("initApp")) {" is never true and the call "swfApp.initApp()" says that this function does not exist. In the original version I added event listeners for HTTPStatusEvent.HTTP_STATUS, IOErrorEvent.IO_ERROR and SecurityErrorEvent.SECURITY_ERROR. But except for HTTP_STATUS = 0 none of them are called. Is the whole idea of how i try to do this wrong ?

  • ASP .NET Button event handlers do not fire on the first click, but on the second click after a PostB

    - by John
    Background: I am customizing an existing ASP .NET / C# application. It has it's own little "framework" and conventions for developers to follow when extending/customizing its functionality. I am currently extending some of it's administrative functionality, to which the framework provides a contract to enforce implementation of the GetAdministrationInterface() method, which returns System.Web.UI.Control. This method is called during the Page_Load() method of the page hosting the GUI interface. Problem: I have three buttons in my GUI, each of which have been assigned an Event Handler. My administration GUI loads up perfectly fine, but clicking any of the buttons doesn't do what I expect them to do. However, when I click them a second time, the buttons work. I placed breakpoints at the beginning of each event handler method and stepped through my code. On the first click, none of the event handlers were triggered. On the second click, they fired. Any ideas? Example of Button Definition (within GetAdministrationInterface) public override Control GetAdministrationInterface() { // more code... Button btn = new Button(); btn.Text = "Click Me!"; btn.Click += new EventHandler(Btn_Click); // more code... } Example of Event Handler Method Definition void Btn_Click(object sender, EventArgs e) { // Do Something } Page_Load Method that calls GetAdministrationInterface protected void Page_Load(object sender, System.EventArgs e) { if (!Page.IsAsync) { List<AdministrationInterface> interfaces = <DATABASE CALL>; foreach(AdministrationInteface ai in interfaces) { placeholderDiv.Controls.Add(ai.GetAdministrationInterface()); } } }

  • Division of text follow the cursor via Javascript/Jquery

    - by webzide
    Dear experts, I wanted have a dynamic division of content follow you with the cursor in the web browser space. I am not a pro at JS so I spent 2 hours to finally debugged a very stupid way to accomplish this. $(document).ready(function () { function func(evt) { var evt = (evt) ? evt : event; var div = document.createElement('div'); div.style.position = "absolute"; div.style.left = evt.clientX + "px"; div.style.top = evt.clientY + "px"; $(div).attr("id", "current") div.innerHTML = "CURSOR FOLLOW TEXT"; $(this).append($(div)); $(this).unbind() $(this).bind('mousemove', function () { $('div').remove("#current"); }); $(this).bind('mousemove', func); } $("body").bind('mousemove', func) }); As you can see this is pretty much Brute force and it slows down the browser quite a bit. I often experience a lag on the browser as a drag my mouse from one place to another. Is there a way to accomplish this easier and faster and more intuitive. I know you can use the cursor image technique but thats something I'm looking to avoid. Thanks in advance.

  • Why I can't get all UDP packets?

    - by Jack
    My program use UdpClient to try to receive 27 responses from 27 hosts. The size of the response is 10KB. My broadband incoming bandwidth is 150KB/s. The 27 responses are sent from the hosts almost at the same time and for every 10 secs. However, I can only receive 8 - 17 responses each time. The number of responses that I can receive is quite dynamic but within the range. Can anyone tell me why? why can't I receive all? I understand UDP is not reliable. but I tried receiving 5 - 10 responses at the same time, it worked. I guess the network links are not so bad. The code is very simple. ON the 27 hosts, I just use UdpClient to send 10KB to my machine. On my machine, I have one UdpClient receive datagrams. Each time I get a data, I create a thread to handle it (basically handling it means just print out "I received 10KB", but it runs in a thread). listener = new UDPListener(Port); listener.Start(); while (true) { try { UDPContext context = listener.Accept(); ThreadPool.QueueUserWorkItem(new WaitCallback(HandleMessage), context); } catch (Exception) { } } If I reduce the size of the response down to 3KB, the case gets much better that roughly 25 responses can be received. Any more idea? UDP buffer problems???

  • No event is firing when placing a custom data bound control in DataRepeater control in Windows forms

    - by Remo
    Hi, Custom events in a custom data bound control are not firing in DataRepeater control. When I debug it I found that the DataRepeater Control recreates the control using Activator.CreateInstance and Copies the Properties and Events. In my case copying events doesn't copy the custom events that I hooked in. For example public class MyClass : Control { public event EventHandler MyEvent; protected virtual void OnMyEvent() { if(this.MyEvent != null) { this.MyEvent(this,EventArgs.Empty); } } private int selectedIndex= -1; public int SelectedIndex { get { return this.selectedIndex; } set { if(this.selectedIndex != value) { this.selectedIndex = value; this.OnMyEvent(); } } } // // DataBinding stuff goes here // } public Form1() { InitialiseComponent(); ArrayList list = new ArrayList(); list.Add("one"); this.dataRepeater1.DataSource = list; // One Repeater MyClass test = new Myclass(); test.DataSource = GetDataTable(); this.dataRepeater1.ItemTemplate.Controls.Add(test); test.MyEvent +=new EventHandler(test_MyEvent); } // This Event should fire when selected index of Datatable is changed and is firing when placed directly in the form and not firing when place in DataRepeater control/////////////////////// private void test_MyEvent(object sender, EventArgss e) { // This event is not fired/////////////////////// } private DataTable GetDataTable() { ..// Create a data Table and return } Any help Appreciated.

  • Dynamically disable custom (VBA) Excel context menu buttons?

    - by Lopsided
    The Scenario Hi guys, I am about to add a few custom controls to the cell context menu in my Excel workbook using the instructions found on this MSDN page. The only problem I am having is that I need the items to only be enabled for a specific column/range of cells. I've looked around, and I've been unable to find any steps for this--there are some for VSTO development (written in C#), but that is not what I need. I plan to write this using the VBA IDE built into Office, and perhaps a bit of XML using the Custom UI Editor. The Question So basically, I'm looking for a way to run a function at the time the context menu is called (i.e., upon right-click) that validates the selection to make sure it is in the appropriate column. If it isn't, I would like my custom buttons to be greyed out. P.S. Please don't think I am asking you to write my code. Creating these buttons should be very simple, as I have created many before (albeit they were all Ribbon items), and I hope it is okay to ask for some quick assistance on this very specific issue. Thank you in advance!

  • How to allow all except part 1 and part 2 ?

    - by Stackfan
    This allows me to get easyly dynamic input variables instead of putting a static prefix like /en/etcetcetc, but the problem is all controllers are blocked. Everything goes to index/index. Question: How can i tell this rule allow evertying as it is now, but do not track if it contains http://site.com/donotcatch/me and http://site.com/iamnotbelongstodynamic1/blabla protected function _initRoutes() { ... $dynamic1 = new Zend_Controller_Router_Route( '/:variable0/:variable1', array( 'controller' => 'index', 'action' => 'index'), array( 'variable0' => '^[a-zA-Z0-9_]*$', 'variable1' => '^[a-zA-Z0-9_]*$', ) ); Follow up: Normally, i always belive yes we can, so, we can do that like this where dynamic1 does not the inter-fare with my other static controllers: // http://site/yeswecan/blabla // variable0 = yeswecan // variable1 = blabla $dynamic1 = new Zend_Controller_Router_Route( '/:variable0/:variable1', array( 'controller' => 'index', 'action' => 'index'), array( 'variable0' => '^[a-zA-Z]*$', 'variable1' => '^[a-z0-9_]*$', ) ); // http://site/ajax/whatever... // solves it $dynamic2 = new Zend_Controller_Router_Route( '/ajax/:variable0', array( 'controller' => 'ajax', 'action' => '' ), array( 'variable0' => '^[a-zA-Z0-9_]*$', ) ); // http://site/order/whatever... // solves it $dynamic3 = new Zend_Controller_Router_Route( '/order/:variable0', array( 'controller' => 'order', 'action' => ''), array( 'variable0' => '^[a-zA-Z0-9_]*$', ) ); Note: Still the controllers are getting failed for example http://site/ajax/whatever always goes to /ajax/index where i wanted to send it as /ajax/user-inserted-value How can i fix the $dynamic2 and $dynamic3 by keeping $dynamic1 ??

  • Using complex where clause in NHibernate mapping layer

    - by JLevett
    I've used where clauses previously in the mapping layer to prevent certain records from ever getting into my application at the lowest level possible. (Mainly to prevent having to re-write lots of lines of code to filter out the unwanted records) These have been simple, one column queries, like so this.Where("Invisible = 0"); However a scenario has appeared which requires the use of an exists sql query. exists (select ep_.Id from [Warehouse].[dbo].EventPart ep_ where Id = ep_.EventId and ep_.DataType = 4 In the above case I would usually reference the parent table Event with a short name, i.e. event_.Id however as Nhibernate generates these short names dynamically it's impossible to know what it's going to be. So instead I tried using just Id, from above ep_ where Id = ep_.EventId When the code is run, because of the dynamic short names the EventPart table short name ep_ is has another short name prefixed to it, event0_.ep_ where event0_ refers to the parent table. This causes an SQL error because of the . in between event0_ and ep_ So in my EventMap I have the following this.Where("(exists (select ep_.Id from [isnapshot.Warehouse].[dbo].EventPart ep_ where Id = ep_.EventId and ep_.DataType = 4)"); but when it's generated it creates this select cast(count(*) as INT) as col_0_0_ from [isnapshot.Warehouse].[dbo].Event event0_ where (exists (select ep_.Id from [isnapshot.Warehouse].[dbo].EventPart event0_.ep_ where event0_.Id = ep_.EventId and ep_.DataType = 4) It has correctly added the event0_ to the Id Was the mapping layer where clause built to handle this and if so where am I going wrong?

  • C++ MFC server app with sockets crashes and I cannot find the fault, help!

    - by usermeister
    My program has one dialog and two sockets. Both sockets are derived from CAsyncSocket, one is for listening, other is for receiving data from client. My program crashes when client tries to connect to server application and server needs to initialize receiving socket. This is my MFC dialog class. class CFileTransferServerDlg : public CDialog { ... ListeningSocket ListenSock; ReceivingSocket* RecvSock; void OnAccept(); // called when ListenSock gets connection attempt ... }; This is my derived socket class for receiving data that calls parent dialogs method when event is signaled. class ReceivingSocket : public CAsyncSocket { CFileTransferServerDlg* m_pDlg; // for accessing parent dialogs controls virtual void OnReceive(int nErrorCode); } ReceivingSocket::ReceivingSocket() { } This is dialogs function that handles incoming connection attempt when listening socket gets event notification. This is where the crash happens. void CFileTransferServerDlg::OnAccept() { RecvSock = new ReceivingSocket; /* CRASH */ } OR void CFileTransferServerDlg::OnAccept() { ReceivingSocket* tmpSock = new ReceivingSocket; tmpSock->SetParentDlg(this); CString message; if( ListenSock.Accept(*tmpSock) ) /* CRASH */ { message.LoadStringW(IDS_CLIENT_CONNECTED); m_txtStatus.SetWindowTextW(message); RecvSock = tmpSock; } } My program crashes when I try to create a socket for receiving file sent from client application. OnAccept starts when Listening socket signals incoming connection attempt, but my application then crashes. I've tried running it on another computer and connection attempt was succesful. What could be wrong? Error in debug mode: Unhandled exception at 0x009c30e1 in FileTransferServer.exe: 0xC0000005: Access violation reading location 0xccccce58.

  • Using in the same time Boost in release and debug mode

    - by Oodini
    Hello, The title is just for teasing. :-) I know it isn't possible, but here is my problem. My app (a DLL, actually) uses Boost. It also uses an external API, which also uses Boost. The external API is of course provided in a release binary, anlong the needed release Boost binaries. When I compile/link my DLL in release mode, I have no problem. I precise I link my app to Boost in a dynamic way (BOOST_ALL_DYN_LINK). In debug mode, I can't load my DLL. I am not sure it is because of Boost, but I suspect Windows doesn't like working with two Boost (the release one called by the external lib, and the debug one called by my code). Will it work better if I link my code statically with the release Boost ? I don't think it is related to CRT, because I have nothing in the Events Viewer. I use Visual Studio 2005 SP1. Thanks.

    - by haansi
    Hi, I am a asp.net developer and don't know much about patterns and architecture. I will very thankful if you can please guide me here. In my web applications I use 4 layers. Web site project (having web forms + code behind cs files, user controls + code behind cs files, master pages + code behind cs files) CustomTypesLayer a class library (having custom types, enumerations, DTOs, constructers, get, set and validations) BusinessLogicLayer a class library (having all business logic, rules and all calls to DAL functions) DataAccessLayer a class library( having just classes communicating to database.) -My user interface just calls BusinessLogicLayer. BusinessLogicLayer do proecessign in it self and for data it calls DataAccessLayer funtions. -Web forms do not calls directly DAL. -CustomTypesLayer is shared by all layers. Please guide me is this approach a pattern ? I though it may be MVC or MVP but pages have there code behind files as well which are confusing me. If it is no patren is it near to some patren ? pleaes guide thanks

  • Building a survey to put in a WordPress website using Python/Django

    - by chiurox
    So I've been given a task to build a survey to get data regarding time slot preferences of prospective students for a particular course. I know there are really quick solutions to this like Google Forms, SurveyMonkey, but since it's not unusually hard, I want to implement the survey myself in a totally new language as an opportunity to get started with it and also be able to customize and provide dynamic info to the users who are voting. Although I have done some stuff in PHP, C++, javascript, etc, I'm pretty new to Python+Django framework but it's something I've been meaning to get into since a long time ago. Initially, what I want is to make a grid with the days of the week as columns and time-durations as rows. In each cell I want to provide users a way to choose how strong (high/medium/low) their preference for this particular day+time is. I also want to show how many "votes" have already been cast for this particular preference because this will influence a lot in their decisions and as a result make this process easier when we are going to define the classes. I'll probably store the data in MySQL. Could anyone point me to some really good Python+Django tutorials for my particular purpose? Does anyone think I'm wasting my time with this trivial task by choosing new tools and that I should just use something I already know (like PHP) or a free service or plugin for Wordpress? Thanks!

  • How to make BoxLayout vertical but children flow top-aligned?

    - by user291701
    I'm trying to get get a vertical, top-aligned layout to work. This is what I have: JPanel pane = new JPanel(); pane.setLayout(new BoxLayout(pane, BoxLayout.Y_AXIS)); MyImagePanel panelImage = new MyImagePanel(); panelImage.setSize(400, 400); pane.add(new JComboBox()); pane.add(panelImage); pane.add(new JButton("1")); pane.add(new JButton("2")); pane.add(new JButton("3")); JFrame frame = new JFrame("Title"); frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); frame.setSize(800, 600); frame.add(pane); frame.pack(); frame.setVisible(true); All the controls appear, but it looks like padding is being applied at run time between their tops and bottoms so they're somewhat vertically centered. This is what I'm going for: ----------------------------------------------------- | ComboBox | | ------------ | | | | | Image | | | | | ------------ | | Button 1 | Any additional space fills the right | ------------ | | Button 2 | | ------------ | | Button 3 | | ------------ | | | | Any additional space fills the bottom | | | ----------------------------------------------------- How do I get BoxLayout to do that? Thanks ------------------------- Update ------------------------- Was able to use this: Box vertical = Box.createVerticalBox(); frame.add(vertical, BorderLayout.NORTH); vertical.add(new JComboBox()); vertical.add(new JButton("1")); ... to get what I wanted.

    - by chucknelson
    I have an ASP ListView, and have a very simple requirement to display numbers as formatted w/ a comma (12,123), while they need to bind to the database without formatting (12123). I am using a standard setup - ListView with a datasource attached, using Bind(). I converted from some older code, so I'm not using ASP.NET controls, just form inputs...but I don't think it matters for this: <asp:SqlDataSource ID="MySqlDataSource" runat="server" ConnectionString='<%$ ConnectionStrings:ConnectionString1 %>' SelectCommand="SELECT NUMSTR FROM MY_TABLE WHERE ID = @ID" UpdateCommand= "UPDATE MY_TABLE SET NUMSTR = @NUMSTR WHERE ID = @ID"> </asp:SqlDataSource> <asp:ListView ID="MyListView" runat="server" DataSourceID="MySqlDataSource"> <LayoutTemplate> <div id="itemplaceholder" runat="server"></div> </LayoutTemplate> <ItemTemplate> <input type="text" name="NUMSTR" ID="NUMSTR" runat="server" value='<%#Bind("NUMSTR")%>' /> <asp:Button ID="UpdateButton" runat="server" Text="Update" Commandname="Update" /> </ItemTemplate> </asp:ListView> In the example above, NUMSTR is a number, but stored as a string in a SqlServer 2008 database. I'm also using the ItemTemplate as read and edit templates, to save on duplicate HTML. In the example, I only get the unformatted number. If I convert the field to an integer (via the SELECT) and use a format string like Bind("NUMSTR", "{0:###,###}"), it writes the formatted number to the database, and then fails when it tries to read it again (can't convert with the comma in there). Is there any elegant/simple solution to this? It's so easy to get the two-way binding going, and I would think there has to be a way to easily format things as well... Oh, and I'm trying to avoid the standard ItemTemplate and EditItemTemplate approach, just for sheer amount of markup required for that. Thanks!

  • kQuery : Trying to find a specific instance of a class by number

    - by mattelliottIT
    I guess I have just hit a mental block with this one; maybe some fresh eyes will help. Basically I have a few instance of the class "menu-item" which when clicked call the click function via jQuery and bring up a video. Instead of giving each on an id as well as a class I am trying to find which instance of the class was clicked (1, 2, 3, etc). Just can't seem to get it though. //click listener for menu-items $('.menu-item').click(function(event) { var o = $('.menu-item'); var count = o.length(); // switch(count) { case 0 : filename == 'letters'; break; case 1 : filename == 'the-gift'; break; } var videoPlayer = '<video controls width="618px">'; videoPlayer += '<source src="_video/' + filename + '.mp4" />'; videoPlayer += '</video>'; //place video $('#videoCont').html(videoPlayer); }); I'm trying to create an array there where each instance of the 'menu-item' is one array item. (btw, for now I am just proofing this with an mp4 filetype before I add in the ogv and webm formats). Thanks for any and all help!

  • How do I post back information from a webpage that has post-generated content?

    - by meanbunny
    Ok so I am very new to html and the web. Right now I am trying to generate list items on the fly and then have them post back to the web server so I know what the person is trying to obtain. Here is the code for generating the list items: foreach (var item in dataList) { MyDataList.InnerHtml += "<li><a runat='server' onclick='li_Click' id='" + item.Name + "-button'></a></li>"; } Further down I have my click event. protected void li_Click(object sender, EventArgs e) { //How do I determine here which item was actually clicked? } My question is how do I determine which list item was clicked? Btw, the code running behind is C#. EDIT 1 LinkButton link = new LinkButton(); link.ID = "all-button"; link.Text = "All"; link.Click += new EventHandler(link_Click); MyDataList.Controls.Add(link); Then below I have my link_Click event that never seems to hit a breakpoint. void link_Click(object sender, EventArgs e) { if (sender != null) { if (sender.GetType() == typeof(LinkButton)) { LinkButton button = (LinkButton)sender; if (button.ID == "all-button") { } } } } I know this has to be possible I just cant figure out what I am missing. Edit 2 Ok ok I think I know what the problem is. I was trying to add a second list inside of another list. This was causing the whole thing to have problems. It is working now.
