binding

问题 I try to understand (without success) why binding behaves differentially when source object is string[] and List<string> . I have two lists, their only difference is ItemsSource - in one case array in second List : XAML code: <StackPanel Background="{ThemeResource ApplicationPageBackgroundThemeBrush}"> <Button Content="Modify items" Click="Button_Click"/> <StackPanel Orientation="Horizontal"> <StackPanel.Resources> <DataTemplate x:Key="ItemTemplate"> <TextBlock Text="{Binding}" FontSize="16"/

问题 Is there any feature of the TextBlock that allows scrolling to the end always? I've seen a number of examples that do this in the code behind , I want to keep the principle of MVVM and not touch the code behind, I'm looking for a way to do this in XAML . Have one? 回答1: I am assuming your TextBlock is nested within a ScrollViewer . In this case you are going to have to create an attached property. See this related question: How to scroll to the bottom of a ScrollViewer automatically with Xaml

问题 Let's pretend I am building a tic-tac-toe game (becouse it's pretty similar as a structure) I want the result to be shown in a popup, with a new game button, and I want this popup to let me access settings (with another button) and change them, always staying within the popup, then leave and finally close it and start a new game. I wish i could keep things ordered and therefore have a separate popup class where i can build my custom popup. I have the newgame method and reset method as method

问题 i have a small code generation question. I have a EJB3 backend that serves DTO objects to a frontend. The frontend uses a configurable binding procedure to map the attributes of the DTO to their forms. At the moment they are doing it by specifing the attributes as strings in ther configuration. The binding implementation uses reflection to acces the attributes. Sounds nice but the problem is, each time we change an attribute name in a DTO, this will not lead to a compile error in the frontend

问题 Where is the best place to find information on binding redirects? or maybe just a basic explanation of where you put these redirects within a project? 回答1: Where you put it can only be configuration. Find details here. 回答2: Why not start from the beginning? after understood what it does, you will end up with something like: <configuration> <runtime> <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1"> <dependentAssembly> <assemblyIdentity name="myAssembly" publicKeyToken=

问题 When I try to set show a toggle inside a loop of value from a dictionary, I get very little help from the error message. If I un-comment the 3 lines of commented code below, trying to add a toggle for each of the properties in the loop, I get the following error: Cannot convert value of type 'HStack, Text, ConditionalContent)>>' to closure result type '_' import SwiftUI struct properties { var id : Int var property : String var isOn : Bool } struct ContentView: View { @State var

问题 I'm currently recoding a bar chart in my app to make use of the Chart class in the WPF Toolkit. Using MVVM, I'm binding the ItemsSource of a ColumnSeries in my chart to a property on my viewmodel. Here's the relevant XAML: <charting:Chart> <charting:ColumnSeries ItemsSource="{Binding ScoreDistribution.ClassScores}" IndependentValuePath="ClassName" DependentValuePath="Score"/> </charting:Chart> And the property on the viewmodel: // NB: viewmodel derived from Josh Smith's BindableObject public
