普通用户控件使用

Posted 2020-08-15 jeffery1010

我们来新建一个用户控件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>

 在新建一个Window窗体，把用户控件添加到Window窗体中

方法如下：

方法一：在xmal中添加

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

然后、把用户控件添加到窗体中

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

代码如下：

<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="下面是用户控件" 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代码中添加

比如我们把用户控件放到容器中

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

然后在后台代码中，实例化用户控件，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);
        }
    }
