namespace CustomController.controller.NewFolder1
{
    public class Find:ContentControl
    {
        private string findStr = string.Empty;
        private TextBox testTextBox;
        private Button testButton;

        public Find()
        {
            this.DefaultStyleKey = typeof(Find);
        }

        public override void OnApplyTemplate()
        {
            base.OnApplyTemplate();

            this.testTextBox = GetTemplateChild("testTextBox") as TextBox;
            this.testButton = GetTemplateChild("testButton") as Button;

            this.testTextBox.Text = "测试一哈，获取或设置ContentControl中元素的值";

            this.testButton.Click += delegate(object sender, RoutedEventArgs e)
            {
                MessageBox.Show(this.testTextBox.Text);
                findStr = this.testTextBox.Text;
            };
        }

        /// <summary>
        /// 外部获取TextBox的值 
        /// </summary>
        /// <returns></returns>
        public string FindStr()
        {
            return findStr;
        }
    }
}

Find.xaml

<ResourceDictionary 
                   xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
                   xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
                   xmlns:local="clr-namespace:CustomController.controller.NewFolder1">
    <Style TargetType="local:Find">
        <Setter Property="Template">
            <Setter.Value>
                <ControlTemplate TargetType="local:Find">
    
                    <Grid HorizontalAlignment="Stretch"
                          VerticalAlignment="Stretch">
                        <Grid.RowDefinitions>
                            <RowDefinition></RowDefinition>
                            <RowDefinition></RowDefinition>
                        </Grid.RowDefinitions>

                        <TextBox x:Name="testTextBox"
                                 Grid.Row="0"></TextBox>
                        <Button x:Name="testButton"
                                    Grid.Row="1"
                                    Content="测试"></Button>
                    </Grid>
                   
                </ControlTemplate>
            </Setter.Value>
        </Setter>
    </Style>
</ResourceDictionary>

在genera.xaml中添加路径:

<ResourceDictionary Source="/CustomController;component/controller/NewFolder1/Find.Theme.xaml"/>

最后在页面中引用

   public MainPage()
        {
            InitializeComponent();

            Find contentControl = new Find();

            Button button = new Button();
            button.Width = 260;
            button.Height = 250;
            button.Content = contentControl;

            this.LayoutRoot.Children.Add(button);

            if (contentControl.FindStr().Trim().Length > 0)
                MessageBox.Show(contentControl.FindStr());
        }

这样就可以实现，自定义的ControlTemplate，读取其中的控件信息；
