在开发 WPF UserControls 时,将子控件的 DependencyProperty 公开为 UserControl 的 DependencyProperty 的最佳方法是什么?以下示例显示了我当前如何在 UserControl 中公开 TextBox 的 Text 属性。当然有更好/更简单的方法来实现这一点?
<UserControl x:Class="WpfApplication3.UserControl1"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
<StackPanel Background="LightCyan">
<TextBox Margin="8" Text="{Binding Text, RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type UserControl}}}" />
</StackPanel>
</UserControl>
using System;
using System.Windows;
using System.Windows.Controls;
namespace WpfApplication3
{
public partial class UserControl1 : UserControl
{
public static DependencyProperty TextProperty = DependencyProperty.Register("Text", typeof(string), typeof(UserControl1), new PropertyMetadata(null));
public string Text
{
get { return GetValue(TextProperty) as string; }
set { SetValue(TextProperty, value); }
}
public UserControl1() { InitializeComponent(); }
}
}
