事件处理器、程序集、XAML注释

事件处理器与代码后置

事件模型：

事件拥有者：btn
事件：click
响应者：MainWindow窗体
处理器：btn1_Click（）方法
事件订阅：Click = “btn1_Click”

C#代码实现订阅 this.button.click+= xxx;

程序集-组件化程序设计

组件：WPF UserControl

<UserControl x:Class="UserControlLibrary.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" 
             xmlns:local="clr-namespace:UserControlLibrary"
             mc:Ignorable="d" 
             d:DesignHeight="300" d:DesignWidth="300" Background="LightBlue">
    <Canvas>
        <Label Content="基本工资" Canvas.Left="45" Canvas.Top="55"/>
        <Label Content="岗位工资" Canvas.Left="45" Canvas.Top="113"/>
        <Label Content="实际工资" Canvas.Left="45" Canvas.Top="171"/>
        <Button Content="Calc" Canvas.Left="54" Canvas.Top="219" RenderTransformOrigin="0.056,0.576" Width="192" Click="btn_Click"/>
        <TextBox x:Name="textBox1" Canvas.Left="126" Canvas.Top="59" Text="TextBox" TextWrapping="Wrap" Width="120"/>
        <TextBox x:Name="textBox2" Canvas.Left="126" Canvas.Top="117" Text="TextBox" TextWrapping="Wrap" Width="120"/>
        <TextBox x:Name="textBox3" Canvas.Left="126" Canvas.Top="175" Text="TextBox" TextWrapping="Wrap" Width="120"/>
    </Canvas>
</UserControl>

MainWindow:
1）添加引用-将组件的引用添加进入
2）xmlns:uercontrol = “”
3) 组件添加进去

<Window x:Class="GridAddUserControl.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
        xmlns:usercontrol="clr-namespace:UserControlLibrary;assembly=UserControlLibrary"
        xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
        xmlns:local="clr-namespace:GridAddUserControl"
        mc:Ignorable="d"
        Title="MainWindow" Height="450" Width="800">
    <Grid>
        <Grid.ColumnDefinitions>
            <ColumnDefinition/>
            <ColumnDefinition/>
        </Grid.ColumnDefinitions>
        <Grid.RowDefinitions>
            <RowDefinition/>
            <RowDefinition/>
        </Grid.RowDefinitions>
        <usercontrol:UserControl1 Grid.Column="0" Grid.Row="0"/>
        <usercontrol:UserControl1 Grid.Column="0" Grid.Row="1"/>
        <usercontrol:UserControl1 Grid.Column="1" Grid.Row="0"/>
        <usercontrol:UserControl1 Grid.Column="1" Grid.Row="1"/>
    </Grid>
</Window>
