从资源重用WPF中的UI

Question

我在UI上有几个标签，我需要在每个标签上显示以下内容：

<StackPanel Orientation="Horizontal">
     <Button Content="&lt;" Command="{Binding MoveToPreviousCommand}" />
     <TextBlock Text="{Binding SelectedItem.Name}" />
     <Button Content="&gt;" Command="{Binding MoveToNextCommand}" />
</StackPanel>

有没有办法避免在XAML中为每个选项卡复制此代码，只需在参考资料中指定上述内容一次并指向每个选项卡下的该资源？

Answer 1

使用ContentControl

 <Window.Resources>       
    <StackPanel x:Key="Content" x:Shared="False" Orientation="Horizontal">
        <Button Content="&lt;" Command="{Binding MoveToPreviousCommand}" />
        <TextBlock Text="{Binding SelectedItem.Name}" />
        <Button Content="&gt;" Command="{Binding MoveToNextCommand}" />
    </StackPanel>

    <DataTemplate x:Key="template1">
        <StackPanel  Orientation="Horizontal">
            <Button Content="&lt;" Command="{Binding MoveToPreviousCommand}" />
            <TextBlock Text="{Binding SelectedItem.Name}" />
            <Button Content="&gt;" Command="{Binding MoveToNextCommand}" />
        </StackPanel>
    </DataTemplate>
</Window.Resources>

<StackPanel>
    <ContentControl Content="{StaticResource Content}"></ContentControl>
    <ContentControl Name="contCtrl" ContentTemplate="{StaticResource template1}" Content="This is the content of the content control."/>
</StackPanel>

使用usercontrol

<UserControl x:Class="WpfApplication2.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">
 <StackPanel  Orientation="Horizontal">
        <Button Content="&lt;" Command="{Binding MoveToPreviousCommand}" />
        <TextBlock Text="{Binding SelectedItem.Name}" />
        <Button Content="&gt;" Command="{Binding MoveToNextCommand}" />
</StackPanel>

<Window x:Class="WpfApplication2.MainWindow"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    Title="MainWindow" Height="350" Width="525"
    xmlns:local="clr-namespace:WpfApplication2">

<Grid>
    <local:UserControl1></local:UserControl1>
</Grid>
