The default databinding on TextBox is TwoWay and it commits the text to the property only when TextBox lost its focus. Is there any easy XAML way to make the databinding happen when I press the Enter key on the TextBox ?. I know it is pretty easy to do in the code behind, but imagine if this TextBox is inside some complex DataTemplate . You can make yourself a pure XAML approach by creating
TextBox上的默认数据绑定是TwoWay ，它仅在TextBox失去焦点时才将文本提交给属性。 当按下TextBox上的Enter键时，是否有任何简单的XAML方法可以使数据绑定发生？ 我知道在后面的代码中很容易做到，但想象一下，如果这个TextBox是在一些复杂的DataTemplate 。 您可以通过创建一个附加行为来使自己成为纯粹的XAML方法。 像这样的东西： public static class InputBindingsManager { public static readonly Dependency
I am really struggling with data binding and the MVVM Methodology, though I like the concept I am just struggling. I have created a WPF for that has multiple comboboxes and a button. The first combobox will list database instance names. the remaining comboboxes will be populated after the button is clicked. Since I am having issues with the first, database instances, combobox I will only show
我真的很困惑数据绑定和MVVM方法，尽管我喜欢我只是在挣扎的概念。 我创建了一个WPF，它有多个组合框和一个按钮。 第一个组合框将列出数据库实例名称。 点击按钮后将填充剩余的组合框。 由于我遇到第一个问题，数据库实例，combobox，我只会显示我的代码。 当应用程序启动时，加载组合框并按预期选择第一个项目。 问题是当我选择一个新名称时，我希望被调用的方法不会。 有人可以帮助我理解为什么我的方法public DBInstan
could someone help me to solve an issue with combobox behaviour. Here is my combobox control (WPF): <ComboBox Grid.Row="1" Grid.Column="1" Margin="6,0,6,6" Name="comboBoxRegionTown" IsEditable="True" IsTextSearchEnabled="True" PreviewKeyUp="comboBoxRegionTown_PreviewKeyUp" IsTextSearchCaseSensitive="False" /> The idea is to make it autocomplete (IsEditable="True" IsTextSearchE
有人可以帮助我解决组合框行为的问题。 这是我的组合框控件（WPF）： <ComboBox Grid.Row="1" Grid.Column="1" Margin="6,0,6,6" Name="comboBoxRegionTown" IsEditable="True" IsTextSearchEnabled="True" PreviewKeyUp="comboBoxRegionTown_PreviewKeyUp" IsTextSearchCaseSensitive="False" /> 这个想法是让它自动完成（IsEditable =“True”IsTextSearchEnabled =“True”）。 所以然后我将任何文本输入到组合框中，
I'm doing a custom control for our company, and I want to define DataTemplate of elements into a ResourceDictionary, for more genericity and skin handling. My control has a ItemsSource property that contains all collection. I also have a DependencyProperty into my control that specificy the name of the property of current Item to bind on. Some code : <DataTemplate x:Key="VEGA_TokenTem
我正在为我们公司进行自定义控制，并且我想将元素的DataTemplate定义到ResourceDictionary中，以获得更多的通用性和皮肤处理。 我的控件有一个包含所有集合的ItemsSource属性。 我还有一个DependencyProperty放入我的控件中，具体指定要绑定的当前Item的属性名称。 一些代码： <DataTemplate x:Key="VEGA_TokenTemplate"> <Border x:Name="Bd" BorderBrush="{StaticResource VEGA_TokenBorderBrush}" BorderThick
I have an ItemsControl with ItemsSource binded to a list of SystemModels. It has to generate an usercontrol for every system in the list. And in those usercontrols it has some textboxes that show the name, is and location of the system. My code creates the usercontrols but doesn't fill the textboxes in the usercontrol. View: <UserControl x:Name="SystemListScreen"> <Scr
我有一个ItemsSource绑定到SystemModels列表的ItemsControl。 它必须为列表中的每个系统生成一个用户控件。 在这些用户控件中，它有一些文本框显示系统的名称，位置和位置。 我的代码创建usercontrols但不填充usercontrol中的文本框。 视图： <UserControl x:Name="SystemListScreen"> <ScrollViewer Grid.Row="1"> <ItemsControl x:Name="SystemList" ItemsSource="{Binding Path
I'm trying to bind the ItemsSource property of an ItemsControl contained in my UserControl (a group of radiobuttons) to a property of the same UserControl. This should be driven by the DependencyProperty when the UserControl is used. But I am not able to make it work, if instead I hardcode the control name the assignment works correctly. This is the class : public partial class GroupList
我试图将包含在我的UserControl（一组单选按钮）中的ItemsControl的ItemsSource属性绑定到同一个UserControl的属性。 当使用UserControl时，这应该由DependencyProperty驱动。 但是我不能使它工作，如果我改写控件名称，分配工作正常。 这是班级： public partial class GroupListBox : UserControl { public GroupListBox() { InitializeComponent(); } private List<RadioButton> _itemsLi
I' writing a control library. In this library there are some custom panels which are populated with user UIElements. Since every child element in my lib must have a "Title" property, I wrote the following: // Attached properties common to every UIElement public static class MyLibCommonProperties { public static readonly DependencyProperty TitleProperty = DependencyPro
我正在写一个控制库。 在这个库中有一些用户UIElements填充的自定义面板。 由于我的lib中的每个子元素都必须具有“Title”属性，因此我写了以下内容： // Attached properties common to every UIElement public static class MyLibCommonProperties { public static readonly DependencyProperty TitleProperty = DependencyProperty.RegisterAttached( "Title", typeof(String),
Is there a way to specify a default property to be referenced by the Path with data binding within XAML? I am looking to be able to do something like what CollectionViewSource does when using Binding. When you bind to a CollectionViewSource within XAML, it is automatically hooking up Path to the View property. Eg: {Binding Source={StaticResource cvs}} is the same as {Binding Path=View, Sourc
有没有一种方法可以指定一个默认属性，由XAML中的数据绑定路径引用？ 我期待能够做到像使用Binding时CollectionViewSource所做的一样。 当绑定到XAML中的CollectionViewSource时，它会自动将Path连接到View属性。 例如：{Binding Source = {StaticResource cvs}}与{Binding Path = View，Source = {StaticResource cvs}}相同 是否可以在自定义的DependencyObject或POCO中做同样的事情？ 将您的属性设置为DataContext。
I need to dynamically load shared objects in Linux (and in the future, OS X, but one thing at a time) and it seems that actually trying to ld-linux.so.2 will always fail with DllNotFoundException. Trying to load it in a C program seems to fail as well (dlopen returns null). Is there any other way to dynamically link libraries in Mono without DllImport, possibly a workaround? You're using
我需要动态加载Linux中的共享对象（以及将来的OS X，但每次只能做一件事），而且似乎实际上试图使用ld-linux.so.2总是会因为DllNotFoundException而失败。 试图加载它在C程序中似乎也失败了（dlopen返回null）。 有没有其他的方式来动态链接单声道没有DllImport库，可能是一种解决方法？ 你正在使用错误的'图书馆'。 你应该使用libdl（它可以在Linux和OSX上运行）。 如果您使用DllImport，但如果需要动态支持，
I need to load a library from a specific directory. Instead of using specific functions like LoadLibrary (Windows) or dlopen (Linux) I would like to temporary add this folder to the search path. So I have: public static void AddOrUpdateDllPath(string dllDirectory) { dllDirectory = dllDirectory.NormalizePathDelimiters("\"); var path = ""; switch (RunningPlatform)
我需要从一个特定的目录加载一个库。 我不想使用LoadLibrary（Windows）或dlopen（Linux）等特定功能，而是暂时将此文件夹添加到搜索路径中。 所以我有： public static void AddOrUpdateDllPath(string dllDirectory) { dllDirectory = dllDirectory.NormalizePathDelimiters("\"); var path = ""; switch (RunningPlatform) { case OperatingSystem.Windows:
