我將如何將串列視圖的寬度設定為與其內部的擴展器的寬度相同？
<Expander x:Name="expander"
IsExpanded="False"
ExpandDirection="Down"
Header="Main"
HorizontalAlignment="Stretch"
Grid.Column="1"
Grid.Row="1">
<Expander.Content>
<ListView x:Name="listView"
SelectionMode="None"
IsItemClickEnabled="True"
HorizontalAlignment="Stretch"
ItemClick="ListItemClicked"
ItemTemplate="{StaticResource ListViewTemplate}"/>
</Expander.Content>
</Expander>
uj5u.com熱心網友回復：
添加HorizontalContentAligment="Stretch"到Expander這樣的。
<Expander
x:Name="expander"
Grid.Row="1"
Grid.Column="1"
HorizontalAlignment="Stretch"
HorizontalContentAlignment="Stretch"
ExpandDirection="Down"
Header="Main"
IsExpanded="False">
<Expander.Content>
<ListView
x:Name="listView"
HorizontalAlignment="Stretch"
IsItemClickEnabled="True"
SelectionMode="None" >
<ListViewItem Content="Test"/>
</ListView>
</Expander.Content>
</Expander>
