binding

问题 I am creating native library binding for the Wikitude SDK. The MonoTouch app fails linking : Undefined symbols for architecture armv7: "std::__1::basic_string, std::__1::allocator >::find_last_of(char const*, unsigned long, unsigned long) const", referenced from: WtUnzip::unzipFileTo(char const*, bool)in WikitudeSDK.a(wtunzip.o) ... My LinkWith: [assembly: LinkWith ("WikitudeSDK.a", LinkTarget.ArmV7, Frameworks = "CoreVideo Security SystemConfiguration CoreMedia AVFoundation CFNetwork

问题 In this example code, I'm trying to offset the Grid 's Canvas position by the height of one of its rows. Does anyone see what I might be doing wrong? As you can see, I tried moving the binding lower in the xaml file, just in case the RowDefinitions needed to be defined first. Either way, it doesn't seem to matter because Canvas.Top is always 0. <Canvas> <Grid Canvas.Top="{Binding ElementName=DetailsRow, Path=ActualHeight}"> <Grid.RowDefinitions> <RowDefinition x:Name="NameRow" />

问题 Hi I am binding a WPF textbox to an Entity Framework property as follows: <TextBox Grid.Column="1" Grid.Row="0" Margin="5,2" Text="{Binding Path=MyEntityObject.SizeLower, Mode=TwoWay}" /> It binds fine to the property and when I change it, it saves to the DB as expected. But if I delete the content of the Textbox I get the red error border around it. I dont have any validator in place so I am guessing the texbox is complaining about the value not being nullable. But in fact this property in

问题 Can anyone explain where the ModelName gets populated from? Looked in MSDN documentation and no explaination here. I am creating a custom model binder and within it I get null for the following: var result = bindingContext.ModelName); 回答1: The ModelBindingContext object is created and populated by whoever calls into the BindModel() method. If the model is coming in as an argument to your action method, this is done by ControllerActionInvoker.GetParameterValue(), and the ModelName property

问题 I was working on a small application using a simple binding in JavaFx 2.1 using java 1.7.0_04-b21 on MacOSX. Actually I currently compare the bind mechanisms of Cocoa on Mac OSX to the JavaFx and face several problems: The application uses a model holding an observableArrayList (called messageList) which is set as the items of a TableView. Adding a new Entry to the list works. The entry appears in the TableView. Issue 1: Deleting a selected item does not work. When I remove an item from the

问题 I used JAXB to bind my xsd's and then tried creating the JAXBContext: JAXBContext jaxbContext = JAXBContext.newInstance("my package name"); But JAXB gives 180 IllegalAnnotationsException. Most of the exceptions have the following messages: XXX is an interface, and JAXB can't handle interfaces XXX does not have a no-arg default constructor @XmlAttribute/@XmlValue need to reference a Java type that maps to text in XML. When I look at the classes generated none of them are interfaces and I can't

问题 I had made a class in C# Windows form to represent my database. It has a master/detail using List<> A record with Employee profile with Trainings(master) and TrainingDetails(detail) Now, how can I display this into 2 datagridview that whenever I select a "Training" from the first datagridview it will display the details on the 2nd datagridview. Its easy to change the datasource of the 2nd datagridview whenever the user select a new item from the first datagridview. But im wondering how it is

问题 Is it possible to bind all widgets to one command, with a single line? It would be nice if I could type in one line as opposed to doing each widget individually. 回答1: You would use the bind_all method on the root window. This will then apply to all widgets (unless you remove the bindtag "all" from some widgets). Note that these bindings fire last, so you can still override the application-wide binding on specific widgets if you wish. Here's a contrived example: import Tkinter as tk class App:
