binding

问题 This question already has answers here : Closed 7 years ago . Possible Duplicate: Enter “&” symbol into a text Label in Windows Forms? On a screen with label controls bound to user-filled properties, I'm getting underlined characters (mnemonics) on the label because the underlying data contains ampersands. For example, if the bound property contains "A&B Trucking", then the label shows as "AB Trucking" with the B underlined. Alt-B on the keyboard would focus that label. How do you prevent

The second TextBlock shows 0, but shouldn't, right? Workaround? 回答1: No, you didn't. ColumnDefinition does have an

问题 I show some items from the database in the list and I want the user to be able to mark some of them as favorites. The best way would be to show some star icon for user to click on which then would turn into slightly different star to indicate that the item is now favorite. What controls should I use for those stars? Could I bind them to some boolean property of the item? 回答1: You can also use vector graphics to achieve this without using png icons. I created this style a while a go, basically

问题 Edit: Old code removed I place it on my MainWindow.xaml <SpinTextBlock:SpinTextBlock Text="{Binding Path=DataContext.WelcomeTitle, ElementName=Window,UpdateSourceTrigger=PropertyChanged}" Height="60" Width="40" x:Name="TextBlock"/> And bind it to a property in MainViewModel.cs public string WelcomeTitle { get { return _welcomeTitle; } set { if (_welcomeTitle == value) { return; } _welcomeTitle = value; RaisePropertyChanged(WelcomeTitle); Dispatcher.CurrentDispatcher.BeginInvoke( new Action

问题 Hopefully a simple question but My google foo is failing me - I've got a maven project where we're using SLF4J with Log4J 1.2 bindings. We now want to move to Log4j 2 particularly for the performance improvement - however, I can't for the life of me find the maven dependency for the log4j 2.0 binding. I've found some notes at http://logging.apache.org/log4j/2.x/log4j-slf4j-impl/ but no mention of any dependency info. I'm also slightly confused by the fact there's apparently two ways to put

问题 I'm working in asp.net with Orckestra CMS (before Composite) and Razor Templates and trying to use Vue framework. All is fine when using {{option.text}} <select class="form-control" id="myExample1"> <option v-for="option in options">{{option.text}}</option> </select> But when I insert v-bind attribute, the page is broken: <select class="form-control" id="myExample1"> <option v-for="option in options" v-bind:value="option.value">{{option.text}}</option> </select> Rendering page fail and show

问题 So imagine this scenario, I have a list and it has a bit of pagination going on, when the user clicks next, the link is hijacked by jQuery, it uses the $.ajax function (of which I've provided below) to go and get the next page contents and display them in the original container. This includes the pagination links as well as we want them to update too. The first page change works fine, but at this stage we've lost the bind between our link element and our jQuery rule: $('#paging a').click

问题 In code I have a Hashtable named MyHashtable . This Hashtable contains an element with key= "Value" , value= 3 . I'm currently trying to bind this value to a textbox. This is my XAML code: <TextBlock Margin="4" Text="{Binding MyHashtable[Value]}" /> <TextBlock Margin="4" DataContext="{Binding MyHashtable}" Text="{Binding [Value]}" /> Q: Why does the second binding not work, while the first binding works just great? For the second binding I have tried other bindings for the text, such as:

问题 In my application I'm using the idle-time of the UI thread to offload expensive operations as described by MSDN article on the WPF Threading Model. GenerateDataAction = () => { GenerateData(); }; Dispatcher.BeginInvoke(GenerateDataAction, DispatcherPriority.Render, null); In the GenerateDate() method I access an MSSQL database, process the data in, and update bindings on the viewmodel. I have noticed since implementing this that some binding fail to update properly or not at all. I have check

问题 I wonder, how to create this binding, since Line.X2 IS NOT dependency property! :( <Line Y1="0" X1="0" Y2="0" Stroke="Blue" StrokeThickness="3" Margin="0 -2 0 -2" X2="{Binding Path=RenderSize.Width, RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type StackPanel}}}"/> 回答1: Line.X2 is a dependency property so you can do this in the normal way: myLine.SetBinding(Line.X2Property, new Binding("RenderSize.Width") { RelativeSource = new RelativeSource(RelativeSourceMode.FindAncestor,
