  • Telerik RadGrid doesn't display on first Page_Load but does on postback

    - by Mark
    I have a page with a drop-down. Based on the selection in the drop-down, data gets loaded and populates a RadGrid. I am using a custom user control for the EditTemplate, so I can't use radGrid.DataBind(). Instead, I have to use radGrid.MasterTableView.Rebind() in association with a NeedDataSource event handler. My problem is that when I load the page initially, I populate the drop-down and automatically select a value (first item in the list) which triggers the databinding on the RadGrid. I can step through the code in debug mode and see that the grid is being populated with data, but when the page displays, it doesn't get rendered. When I then manually choose an item from the drop-down, which triggers the same grid databinding code, it displays properly the second time. How do I get it to display the grid the first time the page loads?

  • Google Chrome: XMLHttpRequest.send() not working while doing POST.

    - by Dave Van den Eynde
    I'm working on an application that allows the user to send a file using a form (a POST request), and that executes a series of GET requests while that file is being uploaded to gather information about the state of the upload. It works fine in IE and Firefox, but not so much in Chrome and Safari. The problem is that even though send() is called on the XMLHttpRequest object, nothing is being requested as can be seen in Fiddler. To be more specific, an event handler is placed on the "submit" event of the form, that places a timeout function call on the window: window.setTimeout(startPolling, 10); and in this function "startPolling" sequence is started that keeps firing GET requests to receive status updates from a web service that returns text/json that can be used to update the UI. Is this a limitation (perhaps security-wise?) on WebKit based browsers? Is this a Chrome bug? (I'm seeing the same behaviour in Safari though).

  • Need explanation for this boost::asio timer example

    - by ApplePieIsGood
    There is a line in the 3rd tutorial on Boost asio that shows how to renew a timer and yet prevent there from being drift. The line is the following: t->expires_at(t->expires_at() + boost::posix_time::seconds(1)); Maybe it's me but I wasn't able to find documentation on the 2nd usage of expires_at(), with no parameters. expires_at(x) sets the new expiration, cancelling any pending completion handlers. So presumably expires_at() does what, return time of the last expiry? So by adding one second, if there should be some number of ms, say n ms, then it will in essence be "subtracted" from the next expiry since the time is being accounted for? What happens then if the time it takes to perform this handler is greater than 1 second in this example? Does it fire immediately?

  • The directory or file specified does not exist on the Web server.

    - by Guy
    I have a hybrid asp.net web forms / mvc application that I recently converted to .net 4 with mvc2. I have set-up that application to run on IIS 7.5 (on Windows 7) and the web forms part of the site is running okay but the MVC part is not. Whenever I try and access a page that needs to go through the routing engine I get HTTP Error 404.0 - Not Found The resource you are looking for has been removed, had its name changed, or is temporarily unavailable. Module IIS Web Core Notification MapRequestHandler Handler StaticFile Error Code 0x80070002 I'm debugging this web site through VS2010 (so I've set-it-up to use IIS instead of Cassini) and when I put a break point in the Application_Start function it is never hit so the routes are never registered. When I put a break point in the Page_Load function in one of the aspx page code-behinds it gets hit. So it seems that the problem is that the route is not being registered. What am I missing?

  • Snow Leopard & Ruby on Rails - SQLite3 issue

    - by spin-docta
    I just upgraded to snow leopard.

  • Asp.Net 3.5 Routing to Asmx Webservice?

    - by Maushu
    I was looking for a way to route http://www.example.com/WebService.asmx to http://www.example.com/service/ using only the ASP.NET 3.5 Routing framework without needing to configure the IIS server. Until now I have done what most tutorials told me, added a reference to the routing assembly, configured stuff in the web.config, added this to the Global.asax: protected void Application_Start(object sender, EventArgs e) { RouteCollection routes = RouteTable.Routes; routes.Add( "WebService", new Route("service/{*Action}", new WebServiceRouteHandler()) ); } ...created this class: public class WebServiceRouteHandler : IRouteHandler { public IHttpHandler GetHttpHandler(RequestContext requestContext) { // What now? } } ...and the problem is right there, I don't know what to do. The tutorials and guides I've read use routing for pages, not webservices. Is this even possible? Ps: The route handler is working, I can visit /service/ and it throws the NotImplementedException I left in the GetHttpHandler method.

  • Shell extension installation not recognized by Windows 7 64-bit shell

    - by Avalanchis
    I have a Copy Hook Handler shell extension that I'm trying to install on Windows 7 64-bit. The shell extension DLL is compiled in two separate versions for 32-bit and 64-bit Windows. The DLL implements DLLRegisterServer which adds the necessary registry entries. After adding the registry entries, it calls the following line of code to nofity the Windows shell: SHChangeNotify(SHCNE_ASSOCCHANGED, SHCNF_IDLIST, NULL, NULL); Everything works great on Windows7 32-bit. The shell recognizes the extension immediately. On 64-bit, the shell extension is only recognized after the shell is restarted. Is there anything I can do to cause the extension to be recognized without restarting the 64-bit shell?

  • WPF Custom Buttons below ListBox Items

    - by Ryan
    WPF Experts - I am trying to add buttons below my custom listbox and also have the scroll bar go to the bottom of the control. Only the items should move and not the buttons.

  • Is there a dojo enhanced grid example with context menu

    - by user102023
    I am looking for an example of a dojo enhanced grid that contains a context menu on either a cell or row menu where the cell or row data is accessed. I have managed to create an enhanced grid with a row context menu. I can create a function that captures the event of clicking on the row menu item. However, I am not sure how to access the row data in the context of the menu item handler. I have not seen any example in the tests of the nightly build. Is there an example of this available online?

  • WatiN LogonDialogHandlers not working correctly in Windows 7

    - by Clint
    I have recently updated to Windows 7, VS2010 and IE8. We have an automation suite running tests against IE using WatiN. These tests require the logon dialog handler to be used in order to log different AD Users into the IE Browser. This works perfectly when using Windows XP and IE8, but now using Windows 7 has resulted in the Windows Security dialog box no longer being recognised, the dialogue box is just being ignored. This is the method being used to startup the browser: public static Browser StartBrowser(string url, string username, string password) { Browser browser = new IE(); WatiN.Core.DialogHandlers.LogonDialogHandler ldh = new WatiN.Core.DialogHandlers.LogonDialogHandler(username, password); browser.DialogWatcher.Add(ldh); browser.GoTo(url); return browser; } any suggestions or help would be greatly appreciated...

  • What is the difference between NavigationService.Navigate() method and PhoneApplicationFrame.Source

    - by afriza
    Taken from Exercise 1: Creating Windows Phone Applications with Microsoft Visual Studio 2010 Express for Windows Phone Task 3: Step 9 // navigate this.NavigationService.Navigate(new Uri("/PuzzlePage.xaml", UriKind.Relative)); Note: The PhoneApplicationPage class provides methods and properties to navigate to pages through its NavigationService property. You can call the Navigate method of the NavigationService and pass the URI for the page as a parameter. You can also use the GoBack and GoForward methods to navigate backward or forward in the navigation history. The hardware back button also provides backward navigation within an application. The event handler shown above uses the NavigationService to go to the PuzzlePage.xaml page. Task 4: Step 3 (RootVisual as Microsoft.Phone.Controls.PhoneApplicationFrame).Source = new Uri("/ErrorPage.xaml", UriKind.Relative); Note: ... Whenever you set the Source property to a value that is different from the displayed content, the frame navigates to the new content. ... What are the differences and similarities of both techniques?

  • Using WPF controls in a background or ASP.Net environment

    - by Moo
    Hi, I have noticed that some WPF controls have some decent effects available to them (drop shadow, reflection etc), and was wondering if it was possible to use these WPF controls solely for their available effects? For example, I have an image manipulation library that resizes and letterboxes disparate sized images but I would like to add drop shadow effects to the resulting images. The WPF image control has this effect available, but how easy is it to use in an environment where there will never be a GUI (console app or ASP.Net library/handler for example). Thoughts? Cheers Moo

  • SmtpClient.SendAsync code review

    - by Lieven Cardoen
    I don't know if this is the way it should be done: { ... var client = new SmtpClient {Host = _smtpServer}; client.SendCompleted += SendCompletedCallback; var userState = mailMessage; client.SendAsync(mailMessage, userState); ... } private static void SendCompletedCallback(object sender, AsyncCompletedEventArgs e) { // Get the unique identifier for this asynchronous operation. var mailMessage= (MailMessage)e.UserState; if (e.Cancelled) { Log.Info(String.Format("[{0}] Send canceled.", mailMessage)); } if (e.Error != null) { Log.Error(String.Format("[{0}] {1}", mailMessage, e.Error)); } else { Log.Info("Message sent."); } mailMessage.Dispose(); } Disposing the mailMessage after the client.SendAsync(...) throws an error. So I need to dispose it in the Callback handler.

  • App.config connection string Protection error

    - by MikeScott8
    I am running into an issue I had before; can't find my reference on how to solve it. Here is the issue. We encrypt the connection strings section in the app.config for our client application using code below: config = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None) If config.ConnectionStrings.SectionInformation.IsProtected = False Then config.ConnectionStrings.SectionInformation.ProtectSection(Nothing) ' We must save the changes to the configuration file.' config.Save(ConfigurationSaveMode.Modified, True) End If The issue is we had a salesperson leave. The old laptop is going to a new salesperson and under the new user's login, when it tries to to do this we get an error. The error is: Unhandled Exception: System.Configuration.ConfigurationErrorsException: An error occurred executing the configuration section handler for connectionStrings. ---> System.Configuration.ConfigurationErrorsException: Failed to encrypt the section 'connectionStrings' using provider 'RsaProtectedConfigurationProvider'.

  • SelectionChanged event binding in Silverlight+MVVM-Light

    - by Budda
    The handler of the "SelectionChanged" event of the ComboBox control has the following signature: void SelectionChangedMethod(object sender, SelectionChangedEventArgs e) How to bind to that property under Silverlight 4 and MVVM-Light to the corresponding method of the ViewModel object? As far as I know, I need to do something like this: public void Changed(Object obj, SelectionChangedEventArgs e) { // .... implement logic here } RelayCommand<Object, SelectionChangedEventArgs> _command; public ICommand ObjectSelectionChanged { get { if (_command == null) { _command = new RelayCommand<Object, SelectionChangedEventArgs>(Changed); } return _command; } } The problem is that RelayCommand class in the MVVM-Light framework doesn't support 2 generic parameters... Is there any solution or workaround for this case? How bind control event to the method with 2 parameters?

  • Websocket TLS Node Server and wss://

    - by CNelson
    I'm looking to start using javascript on the server, most likely with node.js, as well as use websockets to communicate with clients. However, there doesn't seem to be a lot of information about encrypted websocket communication using TLS and the wss:// handler. In fact the only server that I've seen explicitly support wss:// is Kaazing. This TODO is the only reference I've been able to find in the various node implementations. Am I missing something or are the websocket js servers not ready for encrypted communication yet? Another option could be using something like lighttpd or apache to proxy to a node listener, has anyone had success there?

  • trying to override getView in a SimpleCursorAdapter gives NullPointerException

    - by Dimitry Hristov
    Would very much appreciate any help or hint on were to go next. I'm trying to change the content of a row in ListView programmatically. In one row there are 3 TextView and a ProgressBar. I want to animate the ProgressBar if the 'result' column of the current row is zero. After reading some tutorials and docs, I came to the conclusion that LayoutInflater has to be used and getView() - overriden. Maybe I am wrong on this. If I return row = inflater.inflate(R.layout.row, null); from the function, it gives NullPointerException.

  • android maps: How to Long Click a Map?

    - by vamsibm
    Hi. How do I long click on a mapview so that a place marker appears at that point on the map? I tried a couple ways without success: 1) Using setOnLongClickListener on the MapvView which never detected the longclicks. 2) My other idea was to extend MapView to override dispatchTouchEvent .. Create a GestureDetector to respond to longpress callback. But I was stuck midway here as I could not get a handle to my subclassed Mapview. i.e. MyMapview mymapview; //MyMapView extends MapView mymapView = (MyMapView) findViewById(R.id.map); //results in a classcast exception 3) The only other way I know how to try this is: Detect a MotionEvent.ACTION_DOWN and post a delayed runnable to a handler and detect longpress if the two other events: acton_move or an action_up, have not happened. Can someone provide thoughts on any of these methods to detect long presses? Thanks in advance. Bd

  • SAT Thread and Process output capture in c#

    - by alex
    Hi: This is a strange problem I encountered. I have an window application written in c# to do testing. It has a MDI parent form that is hosting a few children forms. One of the forms launch test cripts by creating processes and capture the scripts output to a text box. Another form open serial port and monitoring the status of the device I am working on(like a shell). If I ran both of them together, the output of the script seems only appear in the text box after the test is done. However, If I don't open the serial port form, the output of the script is captured in real time. Does anyone knows what's causing the problem? I notice the onDataReceived even handler for serial port form has a [SAThread] header to it. Will this cause the serial port thread having higher priority than other processes? Thanks in advance.

  • ASP.Net GridView Sorting

    - by Ali Shafai
    I have a grid view with AllowSorting set to true. I get an event onsorting when a sortable header is clicked on. the handler has a parameter "GridViewSortEventArgs e" which has a SortDirection property on it. regardless of how many times you click on the same heading, the SortDirection is always Ascending. I think I'm missing something, like a way to tell the grid "now you are sorted based on column one and in ascending order", so that next time the grid sees a click on the "column one" heading, it decides to go descending. any help appreciated. Cheers, Ali

  • Getting started with zxing on android

    - by amitlicht
    Hi I'm trying to add zxing to my project (add a button which calls the scanner upon press). I found this: http://groups.google.com/group/android-developers/browse_thread/thread/788eb52a765c28b5 and of course the zxing homesite: http://code.google.com/p/zxing/, but still couldn't figure out what to include in the project classpath to make it all work! as for now, I copied the classes in the first link to my project (with some package name changes), and it runs but crashes after pressing the button and trying to install the barcode scanner. some code: private void setScanButton(){ Button scan = (Button) findViewById(R.id.MainPageScanButton); scan.setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { IntentIntegrator.initiateScan(MyActivity.this); } }); } resulting error (from logcat): 06-13 15:26:01.540: ERROR/AndroidRuntime(1423): Uncaught handler: thread main exiting due to uncaught exception 06-13 15:26:01.560: ERROR/AndroidRuntime(1423): android.content.ActivityNotFoundException: No Activity found to handle Intent { act=android.intent.action.VIEW dat=market://search?q=pname:com.google.zxing.client.android } Ideas?

  • WPF TreeView drag and drop using preview

    - by imekon
    I'm handling drag and drop events in a TreeView using PreviewMouseDown, PreviewMouseMove and PreviewMouseUp, however, there is an issue. In my PreviewMouseDown handler, I set everything ready in case there's a drag started (detected in the Move event), however I set e.Handled = true. This means that standard selection events don't get generated on my tree! What I want to be able to do in my Up event is to invoke the standard treeview selection changed event - except I cannot call events outside of the tree. So what's the correct way to do this? I have tried using the standard MouseDown, MouseMove and MouseUp events however there's an issue with messing up my multiple selection feature that means I need to use the Preview version of those events.

  • How can I resolve exception: Error executing child request for ChartImg.axd

    - by macleojw
    I'm using the Chart Controls for Mircosoft .NET Framerwork. Most of the time they work perfectly. However, if I leave a page for longer than 20-30 mins and then try to refresh the page, I get an error saying: Error executing child request for ChartImg.axd. Exception Details: System.Web.HttpException: Error executing child request for ChartImg.axd. If I update the page using an AJAX update panel I get the following error: Sys.WebForms.PageRequestManagerServerErrorException: Error executing child request for ChartImg.axd It seems that the chart handler stops after a period of inactivity. Most of the webpages I've looked at for this error are for situations when this error is displayed all the time. In my case it is only displayed after a period of inactivity. Can someone provide a better explanation of what is happening and suggest a solution?
