简单的WPF绑定不起作用

本文介绍了简单的WPF绑定不起作用的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

我正在学习WPF，但是我一直坚持使用数据绑定.我有一个TreeView，将ItemSource设置为ObserveableCollection<UIBrowserItem>.

I'm learning WPF, and I'm stuck with Data Bindings. I have a TreeView, which ItemSource is set to a ObserveableCollection<UIBrowserItem>.

我的绑定看起来像:

<TreeView> <TreeView.ItemContainerStyle> <Style TargetType="TreeViewItem"> <Setter Property="Header" Value="{Binding Path=Title}"/> </Style> </TreeView.ItemContainerStyle> </TreeView>

我的UIBrowserItem非常基础:

public class UIBrowserItem { public string Title = "Test"; }

但是TreeView中的项目不会设置标题.

But the Items in the TreeView won't have a header set ..

推荐答案

您只能绑定到公共属性，因为您具有公共字段.您的代码应为:

You can only bind to public properties, you have a public field. Your code should be:

public class UIBrowserItem { private String title = "Test"; public string Title { get { return title; } set { title = value; } }

如果标题可以在运行时更改，则还需要实现INotifyPropertyChanged.

If the title can change at run time, you also need to implement INotifyPropertyChanged.
