简介
"用户控件"继承自UserControl,而UserControl继承自ContentControl,也就是内容控件UserControl和Window是一个层次上的，都有xaml和cs文件
流程
创建用户控件
写好用户控件
<UserControl x:Class=
"WpfDemo.UserControlDemo.OwnUserControl"
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> <Grid.RowDefinitions> <RowDefinition Height="*"></RowDefinition> <RowDefinition Height="*"></RowDefinition> </Grid.RowDefinitions> <Label Content="这是一个用户控件"></Label> <Slider Minimum="0" Maximum="100" Grid.Row="1"></Slider> </Grid> </UserControl>
用户控件也可以套用用户控件，组成更复杂的界面
<UserControl x:Class="WpfDemo.UserControlDemo.UseUserControlUserControl"
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:userControlDemo="clr-namespace:WpfDemo.UserControlDemo" mc:Ignorable="d" d:DesignHeight="300" d:DesignWidth="300"> <Grid> <Grid.RowDefinitions> <RowDefinition Height="*"></RowDefinition> <RowDefinition Height="2*"></RowDefinition> <RowDefinition Height="*"></RowDefinition> <RowDefinition Height="*"></RowDefinition> </Grid.RowDefinitions> <Label Content="这是另一个用户控件，在这里使用了OwnUserControl用户控件"></Label> <userControlDemo:OwnUserControl Grid.Row="1"></userControlDemo:OwnUserControl> <Label Grid.Row="2" Content="这个用户控件在OwnUserControl的基础上再添加一个Slider"></Label> <Slider Grid.Row="3" Minimum="0" Maximum="200" ></Slider> </Grid> </UserControl>
窗体引用用户控件
<Window x:Class="WpfDemo.UserControlDemo.UseUserControlWindow"
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:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" xmlns:userControlDemo="clr-namespace:WpfDemo.UserControlDemo" mc:Ignorable="d" Title="UseUserControlWindow" Height="600" Width="400"> <Grid> <Grid.RowDefinitions> <RowDefinition Height="0.2*"></RowDefinition> <RowDefinition Height="*"></RowDefinition> <RowDefinition Height="0.2*"></RowDefinition> <RowDefinition Height="*"></RowDefinition> </Grid.RowDefinitions> <Label Content="使用OwnUserControl用户控件"></Label> <userControlDemo:OwnUserControl Grid.Row="1"></userControlDemo:OwnUserControl> <Label Grid.Row="2" Content="使用UseUserControlUserControl用户控件"></Label> <userControlDemo:UseUserControlUserControl Grid.Row="3"></userControlDemo:UseUserControlUserControl> </Grid> </Window>
