C# 根据密码值WPF停止动画

C# 根据密码值WPF停止动画,c#,wpf,xaml,animation,passwordbox,C#,Wpf,Xaml,Animation,Passwordbox,我在文本块上有一个动画-“labelTextBlock”,它是文本块聚焦时密码框的一部分。。但是当密码框有一个值时,我希望这个动画停止 我用一个文本框来管理它,但我知道这与密码框完全不同。我尝试使用下面的代码,并将动画放在参考资料中,但这导致了这个错误。。 其他信息:在…的名称范围中找不到“Border”名称 代码如下 private void pwdBox_PasswordChanged(object sender, RoutedEventArgs e) { TextBlock La

我在文本块上有一个动画-“labelTextBlock”,它是文本块聚焦时密码框的一部分。。但是当密码框有一个值时,我希望这个动画停止

我用一个文本框来管理它,但我知道这与密码框完全不同。我尝试使用下面的代码,并将动画放在参考资料中,但这导致了这个错误。。 其他信息:在…的名称范围中找不到“Border”名称

代码如下

private void pwdBox_PasswordChanged(object sender, RoutedEventArgs e)
{

    TextBlock LabelTextBlock = pwdBox.Template.FindName("LabelTextBlock", pwdBox) as TextBlock;
    if (pwdBox.SecurePassword.Length == 1)
    {
       Storyboard LabelStoryboard2 = this.Resources["LabelStoryboard2"] as Storyboard;
       LabelStoryboard2.Stop();
    }
    else
    {
       Storyboard LabelStoryboard2 = this.Resources["LabelStoryboard2"] as Storyboard;
       LabelStoryboard2.Begin();
    }
}
这是主要代码

我不确定是否需要删除Isfocused触发器并将其添加到C#?如果我错过了什么,我会道歉

编辑,我也试过这么做?但什么都不做
