slide 技術 mar 另一個 創建 github tro file pos
簡介
"用戶控件"繼承自UserControl,而UserControl繼承自ContentControl,也就是內容控件
UserControl和Window是一個層次上的,都有xaml和cs文件
流程
創建用戶控件
寫好用戶控件
<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="這是一個用戶控件"></Label>
<Slider Minimum="0" Maximum="100" Grid.Row="1"></Slider>
</Grid>
</UserControl>
用戶控件也可以套用用戶控件,組成更復雜的界面
<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="這是另一個用戶控件,在這裏使用了OwnUserControl用戶控件"></Label>
<userControlDemo:OwnUserControl Grid.Row="1"></userControlDemo:OwnUserControl>
<Label Grid.Row="2" Content="這個用戶控件在OwnUserControl的基礎上再添加一個Slider"></Label>
<Slider Grid.Row="3" Minimum="0" Maximum="200" ></Slider>
</Grid>
</UserControl>
窗體引用用戶控件
<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用戶控件"></Label>
<userControlDemo:OwnUserControl Grid.Row="1"></userControlDemo:OwnUserControl>
<Label Grid.Row="2" Content="使用UseUserControlUserControl用戶控件"></Label>
<userControlDemo:UseUserControlUserControl Grid.Row="3"></userControlDemo:UseUserControlUserControl>
</Grid>
</Window>
