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；
