水平拉伸 ItemsControl 中的内容 [英] Horizontally Stretch Content in an ItemsControl

问题描述

我有一个项目控件，但是，项目向左对齐，我不知道如何水平拉伸它们.

I have a itemscontrol, but, the items are being aligned to the left and I can't figure out how to Stretch them Horizontally.

这是我的 XAML:

    <ItemsControl x:Name="ItemsSnaps" ItemsSource="{Binding}" HorizontalContentAlignment="Stretch">
    <ItemsControl.ItemsPanel>
        <ItemsPanelTemplate>
            <StackPanel Orientation="Vertical" HorizontalAlignment="Stretch" VerticalAlignment="Stretch">

            </StackPanel>
        </ItemsPanelTemplate>
    </ItemsControl.ItemsPanel>
    <ItemsControl.ItemTemplate>
        <DataTemplate>
            <Button x:Name="ButtonSnap" HorizontalAlignment="Stretch" Style="{StaticResource EmptyItemSourceAction}" Tag="{Binding}" 
                    toolkit:TiltEffect.IsTiltEnabled="{Binding Converter={StaticResource IValueCheckIfSnapWasRecieved}}"
                    Click="ButtonSnap_Click" 
                    ManipulationCompleted="ButtonSnap_ManipulationCompleted" 
                    ManipulationStarted="ButtonSnap_ManipulationStarted">
                <Grid Tag="{Binding}" Height="80">
                    <Grid.ColumnDefinitions>
                        <ColumnDefinition Width="80" />
                        <ColumnDefinition Width="*" />
                        <ColumnDefinition Width="60" />
                    </Grid.ColumnDefinitions>

                    <Image Grid.Column="0" Source="{Binding Converter={StaticResource IValueIconFromSnapMediaType}}" Margin="10" Stretch="UniformToFill" />

                    <StackPanel Grid.Column="1" VerticalAlignment="Center">
                        <StackPanel Orientation="Horizontal">
                            <TextBlock Foreground="#FF616161" Text="{Binding FallbackValue=alexerax, Converter={StaticResource IValueActiveUserFromSnap}}" FontSize="18.667"></TextBlock>

                            <TextBlock Foreground="#FF616161" FontSize="18.667" Text="-" Margin="5,0,5,0" />

                            <TextBlock Foreground="#FF616161" FontSize="18.667" TextTrimming="WordEllipsis" Text="{Binding Path=Timestamp, FallbackValue=18/08/94 - 14:34, Converter={StaticResource IValueFriendlyTimeFromSnapChatTimestamp}}" />
                        </StackPanel>
                        <TextBlock FontSize="13.333" Text="{Binding FallbackValue=Pending..., Converter={StaticResource IValueFriendlySnapStatus}}">
                            <TextBlock.Foreground>
                                <SolidColorBrush Color="{StaticResource FapAccent}"/>
                            </TextBlock.Foreground>
                        </TextBlock>
                        <ProgressBar Width="150" Visibility="{Binding Converter={StaticResource IValueCheckIfSnapIsDownloading}}" HorizontalAlignment="Stretch" IsIndeterminate="True"></ProgressBar>
                    </StackPanel>

                    <ContentControl VerticalAlignment="Center" Grid.Column="2">
                        <TextBlock Text="10" >
                            <TextBlock.Foreground>
                                <SolidColorBrush Color="{StaticResource FapAccent}"/>
                            </TextBlock.Foreground>
                        </TextBlock>
                    </ContentControl>
                </Grid>
            </Button>
        </DataTemplate>
    </ItemsControl.ItemTemplate>
</ItemsControl>

推荐答案

因此，问题在于我将 Horizo​​ntalAlignment 设置为 Left 的空按钮的样式.VS 大小的方式使那部分代码从屏幕上消失了，所以我看了过去.

So, the issue was with my style for the empty button having HorizontalAlignment set to Left. The way VS was sized made that part of the code go off the screen so i looked right past it.
