[UWP] StackPanel as ItemsControl.ItemsPanel - 项目大小 [英] [UWP]StackPanel as ItemsControl.ItemsPanel - item sizes

问题描述

我有一个ItemsControl，我想垂直添加项目，但我需要它们缩小​​到相同的大小。 基本上，我想要相同的行为，就好像我为每个添加的控件都有一个RowDef为Height = *的Grid。 但是，当我使用
StackPanel作为ItemsPanel时，每个项目都是ItemsControl的大小，因此我必须滚动才能看到我的新项目。 我根本不想滚动，但我也不希望剪切我的项目 - 我需要调整大小。但是，我无法在UWP中找到任何允许我这样做的
。 我假设我错过了一些属性，因为这必须是可能的，但我只是没有看到它。

I've got an ItemsControl where I want to add items vertically, but I need them all to shrink to be of equal size.  Basically, I want the same behavior as if I had a Grid with a RowDef of Height=* for each control I add.  However, when I use a StackPanel as the ItemsPanel, every item is the size of the ItemsControl such that I have to scroll to see my new items.  I don't want to scroll at all, but I also don't want my items to be clipped - I need to resized. However, I cannot find anything in UWP that would allow me to do this.  I'm assuming I am missing some property, as this has to be possible, but I'm just not seeing it.

您可以在  ItemContainerStyle中为项目设置固定高度 

You can just set fixed Height for Items in ItemContainerStyle 

    <Page.Resources>
        <Style x:Key="ListViewItemStyle1" TargetType="ListViewItem" >
            <Setter Property="Height" Value="50" />
        </Style>
    </Page.Resources>
    <Grid Background="{ThemeResource ApplicationPageBackgroundThemeBrush}">
        <ItemsControl x:Name="MyListView" HorizontalAlignment="Stretch" 
                  Margin="10" VerticalAlignment="Stretch"
                  ItemContainerStyle="{StaticResource ListViewItemStyle1}">
            <ListViewItem>
                <Button Height="500" Width="300"/>
            </ListViewItem>
            <ListViewItem>
                <Button Height="500" Width="300"/>
            </ListViewItem>
            <ListViewItem>
                <Button Height="500" Width="300"/>
            </ListViewItem>
        </ItemsControl>
    </Grid>
