WPF 用戶控件的使用

    我們來新建一個用戶控件UserControl1.xaml

<UserControl x:Class="WpfApplicationDemo.Control.UserControl1"
             xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
             xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
             xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" 
             xmlns:d="http://schemas.microsoft.com/expression/blend/2008" 
             mc:Ignorable="d" 
             d:DesignHeight="300" d:DesignWidth="300">
    <Grid>
        <Border BorderThickness="3" CornerRadius ="5"
               Background="#FFFFCC" BorderBrush="#FF6633">
            <StackPanel Orientation="Vertical" Margin="5"                      HorizontalAlignment="Center">
                <Image Name="goodsImage" Height="80" Width="80" Margin="5"></Image>
                <TextBlock Name="goodsPrice" Margin="5"></TextBlock>
                <TextBlock Name="goodsQty" Margin="5"></TextBlock>
                <Image Name="goodsBuy" Source="/images/fbxq_an.gif"                      Height="25" Width="25" Cursor="Hand" Margin="5">
                    <Image.ToolTip>Add Quantity</Image.ToolTip>
                </Image>
            </StackPanel>
        </Border>
    </Grid>

</UserControl>

 在新建一個Window窗體，把用戶控件添加到Window窗體中

方法如下：

方法一：在xmal中添加

首先、要引用用戶控件的命名控件 xmlns:my="clr-namespace:WpfApplicationDemo.Control"

然后、把用戶控件添加到窗體中

<my:UserControl1 HorizontalAlignment="Left" Margin="38,46,0,0" x:Name="userControl11" VerticalAlignment="Top" Height="183" Width="215" />

代碼如下：

<Window x:Class="WpfApplicationDemo.UserControlDemo"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:my="clr-namespace:WpfApplicationDemo.Control"
    Title="UserControlDemo" Height="300" Width="300" Loaded="Window_Loaded">
    <Grid>
        <TextBlock Height="23" HorizontalAlignment="Left" Margin="10,10,0,0" Name="textBlock1" Text="下面是用戶控件" VerticalAlignment="Top" />
        <StackPanel Height="175" HorizontalAlignment="Left" Margin="20,57,0,0" Name="stackPanel1" VerticalAlignment="Top" Width="246" />
        <my:UserControl1 HorizontalAlignment="Left" Margin="38,46,0,0" x:Name="userControl11" VerticalAlignment="Top" Height="183" Width="406" />

    </Grid>
</Window>

方法二：在cs代碼中添加

比如我們把用戶控件放到容器中

 <StackPanel Height="175" HorizontalAlignment="Left" Margin="20,57,0,0" Name="stackPanel1" VerticalAlignment="Top" Width="246" ></StackPanel> 

然后在后台代碼中，實例化用戶控件，添加到容器中即可

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

        private void Window_Loaded(object sender, RoutedEventArgs e)
        {
            UserControl1 demo = new UserControl1();
            this.stackPanel1.Children.Add(demo);
        }
    }
