  • Wpf datagrid row not updating when binded collection updated?

    - by RAJ K
    I have product class class Products { public int ProductID { get; set; } public int Quantity { get; set; } public string Description { get; set; } public decimal Price { get; set; } public decimal SubTotal { get; set; } } public List<Products> ProductsList = new List<Products>(); I have binded this "ProductList" to wpf datagrid. This datagrid shows item already in collection (before DataGrid.DataContext applied) but not showing new item added. I am using List< instead of ObservableCollection< because I want to update items if user changes quantity. I don't know how to do that using ObservableCollection<. Some code will help thanks

  • C++ compiler errors in xamltypeinfo.g.cpp

    - by Richard Banks
    I must be missing something obvious but I'm not sure what. I've created a blank C++ metro app and I've just added a model that I will bind to in my UI however I'm getting a range of compiler warnings related to xamltypeinfo.g.cpp and I'm not sure what I've missed. My header file looks like this: #pragma once #include "pch.h" #include "MyColor.h" using namespace Platform; namespace CppDataBinding { [Windows::UI::Xaml::Data::Bindable] public ref class MyColor sealed : Windows::UI::Xaml::Data::INotifyPropertyChanged { public: MyColor(); ~MyColor(); virtual event Windows::UI::Xaml::Data::PropertyChangedEventHandler^ PropertyChanged; property Platform::String^ RedValue { Platform::String^ get() { return _redValue; } void set(Platform::String^ value) { _redValue = value; RaisePropertyChanged("RedValue"); } } protected: void RaisePropertyChanged(Platform::String^ name); private: Platform::String^ _redValue; }; } and my cpp file looks like this: #include "pch.h" #include "MyColor.h" using namespace CppDataBinding; MyColor::MyColor() { } MyColor::~MyColor() { } void MyColor::RaisePropertyChanged(Platform::String^ name) { if (PropertyChanged != nullptr) { PropertyChanged(this, ref new Windows::UI::Xaml::Data::PropertyChangedEventArgs(name)); } } Nothing too tricky, but when I compile I get errors in xamltypeinfo.g.cpp indicating that MyColor is not defined in CppDataBinding. The relevant generated code looks like this: if (typeName == "CppDataBinding.MyColor") { userType = ref new XamlUserType(this, typeName, GetXamlTypeByName("Object")); userType->Activator = ref new XamlTypeInfo::InfoProvider::Activator( []() -> Platform::Object^ { return ref new CppDataBinding::MyColor(); }); userType->AddMemberName("RedValue", "CppDataBinding.MyColor.RedValue"); userType->SetIsBindable(); xamlType = userType; } If I remove the Bindable attribute from MyColor the code compiles. Can someone tell me what blindingly obvious thing I've missed so I can give myself a facepalm and fix the problem?

  • WPF - Dynamic tooltip

    - by Al Mackenzie
    I have a class ToolTipProvider which has a method string GetToolTip(UIElement element) which will return a specific tooltip for the UIElement specified, based on various factors including properties of the UIElement itself and also looking up into documentation which can be changed dynamically. It will also probably run in a thread so when the form first fires up the tooltips will be something like the visual studio 'Document cache is still being constructed', then populated in the background. I want to allow this to be used in any wpf form with the minimum effort for the developer. Essentially I want to insert an ObjectDataProvider resource into the Window.Resources to wrap my ToolTipProvider object, then I think I need to create a tooltip (called e.g. MyToolTipProvider) in the resources which references that ObjectDataProvider, then on any element which requires this tooltip functionality it would just be a case of ToolTip="{StaticResource MyToolTipProvider}" however I can't work out a) how to bind the actual elemnt itself to the MethodParameters of the objectdataprovider, or b) how to force it to call the method each time the tooltip is opened. Any ideas/pointers on the general pattern I need? Not looking for complete solution, just any ideas from those more experienced

  • WCF, net.tcp, and ASP.NET development server

    - by bryanjonker
    I'm setting up a net.tcp WCF service using instructions here: http://blogs.msdn.com/swiss_dpe_team/archive/2008/02/08/iis-7-support-for-non-http-protocols.aspx One of the steps says to do the following: "If you open the IIS7 management console and you look at the advance setting of our IIS7HostedService Web Application, you will see that in the Enabled Protocols section just http is defined. You now have to add net.tcp (separated by a comma), so that our service will be able to respond also to TCP requests." This is fine, but what if I want to use the Cassini / VS2010 ASP.NET development server to debug (hitting F5 or cntrl-F5)? I don't think there's a way to change the settings in that IIS. Or is there? Are other programmers just so awesome that they don't need to go through the debugger? Or do they use wsHttpBinding?

  • How to explicitly select the row in ListView in WPF?

    - by Ashish Ashu
    I have a ListView in which one of the column contains combo box. I have binded the selectedItem of a Listview, so that I get the current object (selected row ) in the listview.

Please Help!!

  • Current Date in Silverlight XAML TextBlock

    - by user292110
    I am coming from Flex where you can do just about anything inside of curly braces. I am trying to get a TextBlock to display today's Date and Time without just coding it in C#. I have tried many different variations of the following with no luck. TextBlock Text="{Source=Date, Path=Now, StringFormat='dd/MM/yyyy'}" I know I could probably just set a property MyDate and bind to that but why can't I bind directly to the DateTime.Now property?

  • How can I make a grid of clickable images from a list of data in WPF?

    - by mico
    Hello, I am a seasoned C and Java programmer, but an absolute WPF newbie. I am creating a kiosk application that will display a list of images of products that the user will click to see product details and maybe place an order. I am trying to structure my app with MVVM Foundation because I am used to the benefits of structure and tests. I wonder what is the most natural way to create a grid of clickable images that will fill the screen left to right, top to bottom (or the other way round, I have no exact requirements). Any image should be bound to an object that will become current and be displayed in the next screen. Thanks for your help.

  • WPF - Have a list source defined at runtime but still have sample data for design time

    - by Vaccano
    I have some ListBoxes in my WPF app. I would like to be able to view how the design looks with out having to run the app. But I still want to be able to bind to ItemsSource to my View Model. I know I saw a blog post on how to do this, but I cannot seem to find it now. To reiterate, I want dummy data at design time, but real data at run time and not break the MVVM pattern. Any ideas?

  • How do I dinamically load raw assemblies that contains unmanaged code?(bypassing 'Unverifiable code

    - by Thiado de Arruda
    I'm going to give an example of using System.Data.SQLite.DLL which is a mixed assembly with unmanaged code: If I execute this : var assembly= Assembly.LoadFrom("System.Data.SQLite.DLL") No exceptions are thrown, but if I do this : var rawAssembly = File.ReadAllBytes("System.Data.SQLite.DLL"); var assembly = Assembly.Load(rawAssembly); The CLR throws a FileLoadException with "Unverifiable code failed policy check. (Exception from HRESULT: 0x80131402)". Let's say I'm trying to load this assembly on a child AppDomain, how can I customize the AppDomain's security to allow me pass the policy check?

  • Passing Certificate to Svcutil to generate proxy for OSB Service

    - by webwires
    We are wanting to implement Two-Way SSL security from WCF to OSB Services. We have successfully deployed the certificates so that when you browse to the service with IE you get the appropriate prompt for certificate and then it takes you immediately to the WSDL. But, when you attempt to generate a proxy using svcutil as defined in steps 8 and 9 in this MSDN article. http://msdn.microsoft.com/en-us/library/cc949005.aspx I get the error: A reply message was received for operation 'Get' with action 'http://schemas.xmlsoap.org/ws/2004/09/transfer/Get'. However, your client code requires action 'http://schemas.xmlsoap.org/ws/2004/09/transfer/GetResponse'. The OSB services are set to use Soap 1.2 and the svcutil.exe.config we use is identicle to the article except for the findValue and x509FindType. Instead we used the FindByThumbprint pointing to the "My" store name and "CurrentUser" store location. The cert is there and is the same cert we select from the IE prompt.

  • WPF Validation with ContentPresenter

    - by Chris
    Hi, I have a WPF user control which needs to validate some fields. It is bound to a class implementing IDataErrorInfo. When I set the user control as the content of my ContentPresenter in another, already open, window, I can see validation occurring, and error messages being returned, however, I don't get any validation adorner - e.g. the default red outline. If I enter the field and leave it (triggering re-validation) the validation adorner appears. Also, if I show the user control in it's own window it shows the validation adorner immediately. (I'm using Caliburn IResults to do this underneath, e.g. Show.Dialog<VM>(); but I suspect this isn't related) Can anyone offer any suggestion why the validation adorners aren't appearing immediately. (I had guessed animation on my ContentPresenter ContentChanged, however, I have removed this and still experience the problem. thanks, Chris

  • BindAttribute, Exclude nested properties for complex types

    - by David Board
    I have a 'Stream' model: public class Stream { public int ID { get; set; } [Required] [StringLength(50, ErrorMessage = "Stream name cannot be longer than 50 characters.")] public string Name { get; set; } [Required] [DataType(DataType.Url)] public string URL { get; set; } [Required] [Display(Name="Service")] public int ServiceID { get; set; } public virtual Service Service { get; set; } public virtual ICollection<Event> Events { get; set; } public virtual ICollection<Monitor> Monitors { get; set; } public virtual ICollection<AlertRule> AlertRules { get; set; } } For the 'create' view for this model, I have made a view model to pass some additional information to the view: public class StreamCreateVM { public Stream Stream { get; set; } public SelectList ServicesList { get; set; } public int SelectedService { get; set; } } Here is my create post action: [HttpPost] [ValidateAntiForgeryToken] public ActionResult Create([Bind(Include="Stream, Stream.Name, Stream.ServiceID, SelectedService")] StreamCreateVM viewModel) { if (ModelState.IsValid) { db.Streams.Add(viewModel.Stream); db.SaveChanges(); return RedirectToAction("Index", "Service", new { id = viewModel.Stream.ServiceID }); } return View(viewModel); } Now, this all works, apart from the [Bind(Include="Stream, Stream.Name, Stream.ServiceID, SelectedService")] bit. I can't seem to Include or Exclude properties within a nested object.

  • jQuery Autocomplete: how to refresh list?

    - by cinematic
    I have a form with a variable number of autocomplete fields that use the same select list. These fields are added and removed as needed. Whenever a parameter on the page is changed, I (try to) update the list for all the fields by first calling unbind() then autocomplete() with a new parameter added to the url. $('input.foo').unbind().autocomplete(url?new_param=bar); The problem is that unbind() does not seem to be unbinding. When I type in the input field, it fires off the entire history of autocomplete events. I also tried flushCache to no avail. How do I clear out the old events? Thanks.

  • Can a WCF Service provide publish/subscribe activity to a Linux-based C++ client application?

    - by Jeremy Roddingham
    I have a WCF service written to provide certain functionality to intranet-based clients. This is easy when a client is running Windows. I want to implement the same functionality for my Windows clients that is available to my linux clients. My questions are? How can I communicate to a linux c++ based client (supporting callback operations for a publish subscribe) type situation? I am aware of using SOAP over the HTTPBinding but is that the only way (does not support callbacks I believe)? Would the same apply if I were using TCPBinding on the service-side? Currently, the service is set up using TCP but what are my options for the linux client communcation? I read somewhere that messages can also be sent (via webservices I believe) in XML rather than SOAP? Which would be a better approach or how to determine which is a better approach? I am trying to understand the options I would have for a WCF data service if I wanted to communicate with it from a linux client. I appreciate all your help. Thank You, Jeremy

  • C# - Disable Dynamic Keyword

    Is there any way to disable the use of the "dynamic" keyword in .net 4? I thought the Code Analysis feature of VS2010 might have a rule to fail the build if the dynamic keyword is used but I couldn't fine one.

  • ASP.net - First build fails with 'Unknown server tag'

    - by Sophia
    I have multiple custom controls used on a ASPX (and C#) page registered from within the page rather than in Web.Config. On the first build (or rebuild), build fails with error messages for wherever I've used the custom controls. Subsequent builds are successful. The error message: Unknown server tag 'prefix:ExampleControl'. What might cause this, and how can I fix it? Register syntax: <%@ Register Src="ControlsFolder/ExampleControl.ascx" TagName="ExampleControl" TagPrefix="prefix" %> <!-- etc --> Usage syntax: <prefix:ExampleControl runat="server" ID="ExampleControl1" /> <!-- etc -->
