ExpandableContentControl不会调整内容大小调整大小

Question

在树视图上展开并折叠ExpandableContentControl不调整大小。以下是相同的代码：

                    HorizontalContentAlignment="Stretch" 
                    HorizontalAlignment="Stretch"                        
                    MinWidth="225"                         
                    Height="Auto" 
                    >

            <layoutToolkit:AccordionItem  Header="A" >                                    
                <controls:TreeView Margin="5" SizeChanged="TreeView_SizeChanged" Grid.Row="0" Grid.Column="0" UseLayoutRounding="True">
                    <controls:TreeViewItem Header="Controls">
                        <controls:TreeViewItem Header="AutoCompleteBox"/>
                        <controls:TreeViewItem Header="Expander"/>
                        <controls:TreeViewItem Header="NumericUpDown"/>
                    </controls:TreeViewItem>
                    <controls:TreeViewItem Header="Layout">
                        <controls:TreeViewItem Header="DockPanel"/>
                        <controls:TreeViewItem Header="WrapPanel"/>
                        <controls:TreeViewItem Header="Viewbox"/>
                    </controls:TreeViewItem>
                    <controls:TreeViewItem Header="Charting">
                        <controls:TreeViewItem Header="ColumnSeries"/>
                        <controls:TreeViewItem Header="LineSeries"/>
                        <controls:TreeViewItem Header="PieSeries"/>
                    </controls:TreeViewItem>
                </controls:TreeView>

        </layoutToolkit:AccordionItem>


        <layoutToolkit:AccordionItem Content="item 2" Header="B -  long header"/>
        <system:String>regular string item 3</system:String>

    </layoutToolkit:Accordion>
