这两个部分协同工作,XAML 定义了界面的结构和外观,而 code-behind 文件包含处理用户输入、更新界面状态等逻辑。这种分离使开发人员可以更好地组织代码,并且设计人员可以专注于界面的外观和布局,而不用涉及代码的编写。 2. 什么是 WPF? WPF(WindowsPresentationFoundation)是由Microsoft开发的一种用于创建Windows桌面应用程...
Those triggers never fire. I assume it can be done with text factories, added into a template, but in this case I don't know how to create a property trigger programmatically. How can I makeDataTemplates, created from code behind, to react toIsMouseOverchanges? UPD:I've moved the DataTe...

I have tried setting the DataContext="{Binding RelativeSource={RelativeSource Self}}" (instead of setting the DataContext in the code behind) of the items that are bound to the Color Properties in XAML, a rectangle and a polygon, but that didn't seem to work. Thanks in advanc...
这个需求在使用 CodeBehind 的场景很容易实现,但 MVVM 模式就有点难,因为 ViewModel 应该不能直接调用 View 上的任何元素的函数。 如果可以的话,最好通过 ViewModel 上的属性控制UI元素,让这个 UI 元素获得焦点。 这篇文章介绍了两种方式实现这个需求。
So when a Window is initialized, there will be a DataSet instance created. The 2nd and 3rd lines of code are doing master-details data-binding leveraging CollectionViewSource.The generated C# code behind is:private void Window_Loaded(object sender, RoutedEventArgs e){WpfApplication1.Northwind...
where I wrote most of my tools in Python but now I am in a windows heavy environment, and need to share my tools with my team and some need to be GUI driven so I am trying to learn C#/WPF. I'm getting confused on Data Binding to an ObservableCollection in the code behind. I can...
Data Binding on DataGridIn our window we’ll add a DataGrid control, named DataGrid1. Having our structure defined code-side, we must work on this side to link the control to its data source. The binding will be obtained using the control’s ItemsSource property. Our Loaded event will be...

My question is how can i get the binding to work correctly and have my event fire as well. I have tried setting theDataContext="{Binding RelativeSource={RelativeSource Self}}"(instead of setting the DataContext in the code behind) of the items that are bound to the Color Properties in XAML...
