Wpf 折叠/展开分组框
我有以下XAML,其中有三个分组框。在这些组框的标题中有复选框 我想要实现的是:当我选中/取消选中一个框时,我希望相应的groupbox以平滑的动画慢慢展开/折叠 我在Blend 4中尝试了这个,但我还是个新手。关于如何实现这一点有什么帮助吗?特别是,动画可以在XAML中自包含吗 更新:,但我不太明白Wpf 折叠/展开分组框,wpf,xaml,animation,Wpf,Xaml,Animation,我有以下XAML,其中有三个分组框。在这些组框的标题中有复选框 我想要实现的是:当我选中/取消选中一个框时,我希望相应的groupbox以平滑的动画慢慢展开/折叠 我在Blend 4中尝试了这个,但我还是个新手。关于如何实现这一点有什么帮助吗?特别是,动画可以在XAML中自包含吗 更新:,但我不太明白 <UserControl xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x=

您可能应该为此(这就是它们的用途)和使用
如果您不喜欢它们的外观,您可以使它们看起来像一个分组框。刚刚编辑了简单代码中的第一个分组框:
<GroupBox Margin="8,0" BorderBrush="#FF88B1D8" Height="150">
<GroupBox.Resources>
<Style TargetType="GroupBox">
<Style.Triggers>
<EventTrigger RoutedEvent="CheckBox.Unchecked">
<BeginStoryboard>
<Storyboard>
<DoubleAnimation Storyboard.TargetProperty="Height" Duration="0:0:.2" To="30" />
</Storyboard>
</BeginStoryboard>
</EventTrigger>
<EventTrigger RoutedEvent="CheckBox.Checked">
<BeginStoryboard>
<Storyboard>
<DoubleAnimation Storyboard.TargetProperty="Height" Duration="0:0:.2" />
</Storyboard>
</BeginStoryboard>
</EventTrigger>
</Style.Triggers>
</Style>
</GroupBox.Resources>
<GroupBox.Header>
<WrapPanel>
<CheckBox IsChecked="True" VerticalAlignment="Center" />
<Label Content="Volatility" Background="#00000000" Foreground="#FF0033FF" FontWeight="Bold" />
</WrapPanel>
</GroupBox.Header>
<UniformGrid Columns="2">
<Label Content="Spots"></Label>
<TextBox AcceptsReturn="False" AcceptsTab="True" AllowDrop="True" IsTabStop="True" />
<Label Content="Hist. references" />
<TextBox AcceptsReturn="False" AcceptsTab="True" AllowDrop="True" IsTabStop="True" />
<Label Content="Tenors" />
<TextBox AcceptsReturn="False" AcceptsTab="True" AllowDrop="True" IsTabStop="True" />
</UniformGrid>
</GroupBox>
但是,如何指定from=“Auto”?目前,默认值也有点奇怪,如何获得更小的时间跨度?我试过0:0:0.5和0:0:0:1,两种方法都会导致exceptions@jeromeG您必须在20%的时间内这样指定它(0:0:.2:)不指定“to”会在运行时引发异常非常感谢所有这些答案;)
