文本框数据绑定到字符串依赖项参数不起作用 [英] Text Box data binding to the string dependency parameter is not working

问题描述

当我尝试使用字符串控件绑定文本框时，在文本框中更改的文本不会显示在消息框中.代码片段为:

//.xaml文件

When I try to bind a text box with the string control, the text changed in the text box is not displayed in the messagebox. The code snippets are:

//The .xaml file

<Window x:Class="Databinding3.Window1"

    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

    Title="Window1" Height="207" Width="300">
    <Grid>
        <StackPanel Margin="28,44,20,36" Name="stackPanel1" Orientation="Horizontal">
            <TextBox Height="23" Name="textBox1" Width="120" Text="{Binding Path=FullName}"/>
            <Separator Width="20" Visibility="Hidden"></Separator>
            <Button  Height="23" Name="button1" Width="75" Click="button1_Click">Button</Button>
        </StackPanel>
    </Grid>
</Window>

.cs文件

The .cs file

namespace Databinding3
{
    /// <summary>
    /// Interaction logic for Window1.xaml
    /// </summary>
    public partial class Window1 : Window
    {
        public Window1()
        {
            InitializeComponent();
        }



        public string FullName
        {
            get { return (string)GetValue(FullNameProperty); }
            set { SetValue(FullNameProperty, value); }
        }

        // Using a DependencyProperty as the backing store for FullName.  This enables animation, styling, binding, etc...
        public static readonly DependencyProperty FullNameProperty =
            DependencyProperty.Register("FullName", typeof(string), typeof(Window1), new UIPropertyMetadata(string.Empty));

        private void button1_Click(object sender, RoutedEventArgs e)
        {
            MessageBox.Show(FullName, "Full Name");
        }
    }
}

推荐答案

在哪里设置文本框以将窗口用作数据上下文? IMO，这对现实世界代码不是有用的.

Where do you set the Textbox to use the window as it''s data context ? This is not useful real world code, IMO.

我是WPF的初学者.您能否帮助我如何将数据上下文设置为文本框
