如何查看我的 silverlight 控件是否已“最小化”?或“最大化”

Silverlight 新手,所以如果这个问题的措辞不正确,我深表歉意。

我正在玩 Richtextbox 和故事板动画。基本上,在 mouseenter 上动画为 100px,在 mouseleave 上动画为 0px。

这是相当基本的,但我不知道如何查看它是否处于最小化或最大化状态。

这是 XAML:

<UserControl x:Class="AnotherTester.MainPage"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
mc:Ignorable="d"
d:DesignHeight="300" d:DesignWidth="400">
<UserControl.Resources>
    <Storyboard x:Name="Shrink">
        <DoubleAnimation Storyboard.TargetName="textBox" 
            Storyboard.TargetProperty="Height"
            From="100" To="0" Duration="00:00:00.5" />
    </Storyboard>
    <Storyboard x:Name="Grow">
        <DoubleAnimation Storyboard.TargetName="textBox" 
            Storyboard.TargetProperty="Height"
            From="0" To="100" Duration="00:00:00.5" />
    </Storyboard>
</UserControl.Resources>
    <Grid x:Name="LayoutRoot" Background="White">
    <StackPanel HorizontalAlignment="Left" VerticalAlignment="Top" Width="100">
        <Rectangle x:Name="rectangle" Fill="#FF0202F9" Height="20" Stroke="Black" Width="100" MouseEnter="rectangle_MouseEnter" MouseLeave="rectangle_MouseLeave" />
        <RichTextBox x:Name="textBox" Height="100">
            <Paragraph><Run Text="This"/></Paragraph>
            <Paragraph><Run Text="is"/></Paragraph>
            <Paragraph><Run Text="some"/></Paragraph>
            <Paragraph><Run Text="awesome"/></Paragraph>
            <Paragraph><Run Text="text"/></Paragraph>
        </RichTextBox>
    </StackPanel>

</Grid>

以及背后的代码:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Net;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Documents;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Animation;
using System.Windows.Shapes;

namespace AnotherTester
{
public partial class MainPage : UserControl
{

    public MainPage()
    {
        InitializeComponent();
    }

    private void rectangle_MouseEnter(object sender, MouseEventArgs e)
    {
        Grow.Begin();
    }

    private void rectangle_MouseLeave(object sender, MouseEventArgs e)
    {    
        Shrink.Begin();
    }
}
}

编辑: 好吧,我只是将控件的起始高度更改为 0px,这给了我想要的效果(所有折叠的框,直到我们将鼠标悬停在它们上方),但我仍然想知道如何检查这样的事情..

Silverlight newbie here, so I apologize if this question isn't even worded correctly.

I am playing around with a richtextbox and storyboard animations. Basically, on mouseenter animate to 100px, on mouseleave animate to 0px.

This is fairly basic, but what I can't figure out is how to see if it is in the minimize or maximize state.

Here is the XAML:

<UserControl x:Class="AnotherTester.MainPage"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
mc:Ignorable="d"
d:DesignHeight="300" d:DesignWidth="400">
<UserControl.Resources>
    <Storyboard x:Name="Shrink">
        <DoubleAnimation Storyboard.TargetName="textBox" 
            Storyboard.TargetProperty="Height"
            From="100" To="0" Duration="00:00:00.5" />
    </Storyboard>
    <Storyboard x:Name="Grow">
        <DoubleAnimation Storyboard.TargetName="textBox" 
            Storyboard.TargetProperty="Height"
            From="0" To="100" Duration="00:00:00.5" />
    </Storyboard>
</UserControl.Resources>
    <Grid x:Name="LayoutRoot" Background="White">
    <StackPanel HorizontalAlignment="Left" VerticalAlignment="Top" Width="100">
        <Rectangle x:Name="rectangle" Fill="#FF0202F9" Height="20" Stroke="Black" Width="100" MouseEnter="rectangle_MouseEnter" MouseLeave="rectangle_MouseLeave" />
        <RichTextBox x:Name="textBox" Height="100">
            <Paragraph><Run Text="This"/></Paragraph>
            <Paragraph><Run Text="is"/></Paragraph>
            <Paragraph><Run Text="some"/></Paragraph>
            <Paragraph><Run Text="awesome"/></Paragraph>
            <Paragraph><Run Text="text"/></Paragraph>
        </RichTextBox>
    </StackPanel>

</Grid>

And the code Behind:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Net;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Documents;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Animation;
using System.Windows.Shapes;

namespace AnotherTester
{
public partial class MainPage : UserControl
{

    public MainPage()
    {
        InitializeComponent();
    }

    private void rectangle_MouseEnter(object sender, MouseEventArgs e)
    {
        Grow.Begin();
    }

    private void rectangle_MouseLeave(object sender, MouseEventArgs e)
    {    
        Shrink.Begin();
    }
}
}

EDIT:
Ok, I just changed the starting height of the control to 0px, which gave me the effect I was looking for (all collapsed boxes until we mouse over them), but I would still like to know how to check against things like this..

解决方案是使用情节提要完成事件来让您设置状态。

例子

Grow.Completed += (o,e) => _isCollapsed = true;

on solution would be to use the storyboards completed event to let you set the state.

example

Grow.Completed += (o,e) => _isCollapsed = true;
