动态移除控件后调整大小答案

【问题标题】：Adjust size after dynamically removing a controle动态移除控件后调整大小

【问题描述】：

我有一个自定义图形用户控件，我已将它放在堆栈面板中。堆栈面板中最多可以随时显示 4 个图形控件。我有复选框来控制图表的可见性。

我遇到的问题是，当我取消选中一个复选框时，堆栈面板中的剩余图形不会调整大小以弥补额外的空间。我正在寻找的是当所有图表都可见时，它们适合屏幕而不滚动，但如果只有一个图表可见，我希望调整其大小以占用所有空间。

有人有什么想法吗？

这是我目前所拥有的：

<UniformGrid Grid.Row="2" Name="uniformGrid1" >
                <UniformGrid.Resources>
                    <Utilities:BooleanToVisibilityConverter x:Key="BooleanToVisibilityConverter"/>
                </UniformGrid.Resources>

            <StackPanel Grid.Row="1" Height="700"  Name="graphControls" Orientation="Vertical">
                <!--Cross Correlation Graph-->
                <View:Graph Width="Auto" Height="Auto" MinHeight="175" Margin="5" x:Name="CrossCorrelationGraph" x:FieldModifier="public"                                                
                        Visibility="{Binding Path=IsChecked, ElementName=crossCorrelationViewCheck, Converter={StaticResource BooleanToVisibilityConverter}}"
                        GraphMetadata="{Binding Path=Processor.CrossCorrelation.CrossCorrelationGraphData}"
                        StartPointAlignment="CenterVertical"
                        GraphTitle="Cross Correlation"
                        IsDetailed="True"/>

                <!--Power Spectrum Graph-->
                <View:Graph Width="Auto" Height="Auto" MinHeight="175" Margin="5" x:Name="PowerSpectrumGraph" x:FieldModifier="public"
                        Visibility="{Binding Path=IsChecked, ElementName=powerSpectrumViewCheck, Converter={StaticResource BooleanToVisibilityConverter}}"
                        GraphMetadata="{Binding Path=Processor.CrossCorrelation.PowerSpectrumGraphData}"
                        StartPointAlignment="Left"
                        GraphTitle="Power Spectrum"
                        IsDetailed="True"/>

            <!--Phase Spectrum-->
                <View:Graph  Width="Auto" Height="Auto" MinHeight="175" Margin="5" x:Name="PhaseSpectrum" x:FieldModifier="public"
                        Visibility="{Binding Path=IsChecked, ElementName=phaseSpectrumViewCheck, Converter={StaticResource BooleanToVisibilityConverter}}"
                        GraphMetadata="{Binding Path=Processor.CrossCorrelation.PhaseSpectrumGraphData}"
                        StartPointAlignment="CenterHorizontal"
                        GraphTitle="Cross Phase Spectrum"
                        IsDetailed="True"/>

                <!--Amplitude Spectrum-->
                <View:Graph  Width="Auto" Height="Auto" MinHeight="175" Margin="5" x:Name="AmplitudeSpectrumGraph" x:FieldModifier="public"

                        StartPointAlignment="Left"
                        GraphTitle="Cross Amplitude Spectrum"
                        IsDetailed="True"/>
            </StackPanel>
        </UniformGrid>

【解决方案1】：

玩了一段时间后，我找到了解决方案。我会在这里发布，以便其他人受益。

首先，我放弃了堆栈面板，只使用了 UniformGrid。我将 UniformGrid 上的 columns 属性设置为 1，因此所有内容都将一个在另一个之上。现在一切正常。

<UniformGrid  Grid.Row="2"  Height="Auto"  Columns="1">                
                    <UniformGrid.Resources>
                        <Utilities:BooleanToVisibilityConverter x:Key="BooleanToVisibilityConverter"/>
                    </UniformGrid.Resources>
                    <!--Cross Correlation Graph-->
            <View:Graph Width="Auto" Height="Auto" MinHeight="175" Margin="5" x:Name="CrossCorrelationGraph" x:FieldModifier="public"                                                
                        Visibility="{Binding Path=IsChecked, ElementName=crossCorrelationViewCheck, Converter={StaticResource BooleanToVisibilityConverter}}"
                        GraphMetadata="{Binding Path=Processor.CrossCorrelation.CrossCorrelationGraphData}"
                        StartPointAlignment="CenterVertical"
                        GraphTitle="Cross Correlation"
                        IsDetailed="True"/>

                    <!--Power Spectrum Graph-->
            <View:Graph Width="Auto" Height="Auto" MinHeight="175" Margin="5" x:Name="PowerSpectrumGraph" x:FieldModifier="public"
                        Visibility="{Binding Path=IsChecked, ElementName=powerSpectrumViewCheck, Converter={StaticResource BooleanToVisibilityConverter}}"
                        GraphMetadata="{Binding Path=Processor.CrossCorrelation.PowerSpectrumGraphData}"
                        StartPointAlignment="Left"
                        GraphTitle="Power Spectrum"
                        IsDetailed="True"/>

                    <!--Phase Spectrum-->
            <View:Graph  Width="Auto" Height="Auto" MinHeight="175" Margin="5" x:Name="PhaseSpectrum" x:FieldModifier="public"
                        Visibility="{Binding Path=IsChecked, ElementName=phaseSpectrumViewCheck, Converter={StaticResource BooleanToVisibilityConverter}}"
                        GraphMetadata="{Binding Path=Processor.CrossCorrelation.PhaseSpectrumGraphData}"
                        StartPointAlignment="CenterHorizontal"
                        GraphTitle="Cross Phase Spectrum"
                        IsDetailed="True"/>

                    <!--Amplitude Spectrum-->
            <View:Graph  Width="Auto" Height="Auto" MinHeight="175" Margin="5" x:Name="AmplitudeSpectrumGraph" x:FieldModifier="public"
                        Visibility="{Binding Path=IsChecked, ElementName=amplitudeSpectrumViewCheck, Converter={StaticResource BooleanToVisibilityConverter}}"
                        StartPointAlignment="Left"
                        GraphTitle="Cross Amplitude Spectrum"
                        IsDetailed="True"/>
                </UniformGrid>
