c# – 引用ControlTemplate内部的控件

作者:互联网

我如何在代码隐藏中形成我的构造函数,在下面的XAML中获取对OuterBorder控件的引用?

<Window Template="{DynamicResource WindowTemplate}">
    <Window.Resources>      
        <ControlTemplate x:Key="WindowTemplate" TargetType="{x:Type Window}">
            <AdornerDecorator>
                <Border Name="OuterBorder" Background="Black" BorderBrush="Red" BorderThickness="1" CornerRadius="0">
                    <!-- Implementation here... -->
                </Border>
            </AdornerDecorator>
        </ControlTemplate>
    </Window.Resources>
</Window>

解决方法:

两种可能的解决方

解决方案1

在XAML中放置一个Loaded事件

<Border Name="OuterBorder" Loaded="Border_Loaded" ...

并在代码后面存储它在私人领域:

private Border border;

void Border_Loaded(object sender, RoutedEventArgs e)
{
    this.border = (Border)sender;
}

要么:

解决方案2

覆盖窗口的OnApplyTemplate:

private Border border;

public override void OnApplyTemplate()
{
    base.OnApplyTemplate();
    this.border = (Border) Template.FindName("OuterBorder", this);
}
