Question

我在旋转控件中设置listboxitem的样式有问题。我想拉伸它。我不确定我是否应该提及它因为它不应该对它产生影响，但是这个列表框是通过捕获滚动事件来动态填充的。我试过这个解决方案，但没有成功：

    <ListBox.ItemContainerStyle>
           <Style TargetType="ListBoxItem">
                 <Setter Property="HorizontalAlignment" Value="Stretch"/>
                 <Setter Property="HorizontalContentAlignment" Value="Stretch"/>
           </Style>
</ListBox.ItemContainerStyle>

以下是整个pivotItem的代码：

<controls:PivotItem Header="Indeks">
            <Grid Name="grd_Content" HorizontalAlignment="Stretch" Background="Transparent">
                <Grid.RowDefinitions>
                    <RowDefinition></RowDefinition>
                    <RowDefinition></RowDefinition>
                </Grid.RowDefinitions>

                <ListBox x:Name="lbx_Index" HorizontalAlignment="Left" Margin="10,10,0,0" VerticalAlignment="Top" Foreground="White" Loaded="lbx_Index_Loaded" Template="{StaticResource ListBoxControlTemplate}" Grid.Row="1" Tap="lbx_Index_Tap" Background="{x:Null}">
                        <ListBox.ItemContainerStyle>
                            <Style TargetType="ListBoxItem">
                                <Setter Property="HorizontalAlignment" Value="Stretch"/>
                                <Setter Property="HorizontalContentAlignment" Value="Stretch"/>
                            </Style>
                        </ListBox.ItemContainerStyle>
                        <ControlTemplate TargetType="ListBox">
                        <ScrollViewer x:Name="scrollViewer" 
                              BorderBrush="Transparent"
                              BorderThickness="0"
                              Background="MediumAquamarine"
                              Foreground="Transparent"
                              HorizontalAlignment="Stretch"       
                              Padding="{TemplateBinding Padding}"
                              Loaded="ScrollViewer_Loaded">
                            <ItemsPresenter HorizontalAlignment="Stretch"/>
                        </ScrollViewer>
                    </ControlTemplate>
                    <ListBox.DataContext>
                        <local:ListBoxPart/>
                    </ListBox.DataContext>
                    <ListBox.ItemTemplate>

                                        <RowDefinition/>
                                        <RowDefinition/>
                                    </Grid.RowDefinitions>
                                    <Grid.ColumnDefinitions>

注意，您不需要将Horrizontal对齐设置设置为拉伸，除非它位于覆盖它的容器中。默认情况下，大多数XAML控件都设置为占用最多空间。

同时检查您的边距是否没有将容器缩小到您想要的位置。（注意你也可以使用负边距来拉伸）

列表框项目不想拉伸
