wpf模板问题

怎么向模板里面的控件加内容啊，比如我做了个textbox控件的样式，里面有个controltemplate，里面有个grid，grid有2个元素：button和textbox1。我在主界面调用了这个模板的样式后，怎么读取textbox1的text？

Answer 1

模板内的属性可以绑定到控件本身的属性，关键字是TemplateBinding

<Window x:Class="WpfApplication5.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        Title="MainWindow" Height="350" Width="525" Loaded="Window_Loaded">
    <Grid>
        <TextBox Name="textBox1" HorizontalAlignment="Center" VerticalAlignment="Center">
            <TextBox.Template>
                <ControlTemplate TargetType="TextBox">
                    <Grid>
                        <Grid.ColumnDefinitions>
                            <ColumnDefinition/>
                            <ColumnDefinition Width="auto"/>
                        </Grid.ColumnDefinitions>
                        <TextBox Text="{TemplateBinding Text}" Background="LightBlue" MinWidth="50"/>
                        <Button Grid.Column="1">button1</Button>
                    </Grid>
                </ControlTemplate>
            </TextBox.Template>
        </TextBox>
    </Grid>
</Window>

    public partial class MainWindow : Window
    {
        public MainWindow()
        {
            InitializeComponent();
        }

        private void Window_Loaded(object sender, RoutedEventArgs e)
        {
            this.textBox1.Text = "Hello World!";
        }
    }
