Wp7：获取ControlTemplate中的元素信息

Find.cs类

View Code 
 1 using System;
 2 using System.Net;
 3 using System.Windows;
 4 using System.Windows.Controls;
 5 using System.Windows.Documents;
 6 using System.Windows.Ink;
 7 using System.Windows.Input;
 8 using System.Windows.Media;
 9 using System.Windows.Media.Animation;
10 using System.Windows.Shapes;
11 
12 namespace CustomController.controller.NewFolder1
13 {
14     public class Find:ContentControl
15     {
16         private string findStr = string.Empty;
17         private TextBox testTextBox;
18         private Button testButton;
19 
20         public Find()
21         {
22             this.DefaultStyleKey = typeof(Find);
23         }
24 
25         public override void OnApplyTemplate()
26         {
27             base.OnApplyTemplate();
28 
29             this.testTextBox = GetTemplateChild("testTextBox") as TextBox;
30             this.testButton = GetTemplateChild("testButton") as Button;
31 
32             this.testTextBox.Text = "测试一哈，获取或设置ContentControl中元素的值";
33 
34             this.testButton.Click += delegate(object sender, RoutedEventArgs e)
35             {
36                 MessageBox.Show(this.testTextBox.Text);
37                 findStr = this.testTextBox.Text;
38             };
39         }
40 
41         /// <summary>
42         /// 外部获取TextBox的值 
43         /// </summary>
44         /// <returns></returns>
45         public string FindStr()
46         {
47             return findStr;
48         }
49     }
50 }

Find.xaml

View Code 
 1 <ResourceDictionary 
 2                    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
 3                    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
 4                    xmlns:local="clr-namespace:CustomController.controller.NewFolder1">
 5     <Style TargetType="local:Find">
 6         <Setter Property="Template">
 7             <Setter.Value>
 8                 <ControlTemplate TargetType="local:Find">
 9     
10                     <Grid HorizontalAlignment="Stretch"
11                           VerticalAlignment="Stretch">
12                         <Grid.RowDefinitions>
13                             <RowDefinition></RowDefinition>
14                             <RowDefinition></RowDefinition>
15                         </Grid.RowDefinitions>
16 
17                         <TextBox x:Name="testTextBox"
18                                  Grid.Row="0"></TextBox>
19                         <Button x:Name="testButton"
20                                     Grid.Row="1"
21                                     Content="测试"></Button>
22                     </Grid>
23                    
24                 </ControlTemplate>
25             </Setter.Value>
26         </Setter>
27     </Style>
28 </ResourceDictionary>

在genera.xaml中添加路径:

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

最后在页面中引用

 1    public MainPage()
 2         {
 3             InitializeComponent();
 4 
 5             Find contentControl = new Find();
 6 
 7             Button button = new Button();
 8             button.Width = 260;
 9             button.Height = 250;
10             button.Content = contentControl;
11 
12             this.LayoutRoot.Children.Add(button);
13 
14             if (contentControl.FindStr().Trim().Length > 0)
15                 MessageBox.Show(contentControl.FindStr());
16         }

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