Question

如何在WPF中创建ListView填充所有可用空间？我尝试过很多很多东西，但都没有。

最近我尝试将ListView嵌套在DockPanel中，然后使用ListView上的绑定来获取DockPanel的ActualHeight。这很好用，但容器中还有其他控件，需要适应它们。

我真的不想编写OnControlLoaded（）和OnControlResized（）事件并在代码中调整ListView的大小。我该怎么办？

这是XAML，第10行有违规的SortableListView。

    <DockPanel>
        <StackPanel DockPanel.Dock="Top" Orientation="Horizontal" Margin="15 5 5 5">
            <Button x:Name="btnAddCost" Padding="3" ToolTip="Add Cost" Margin="0 0 5 0" Click="btnAddCost_Click"  >
                Add Cost
            </Button>
            <Button x:Name="btnDeleteCost" Padding="3" ToolTip="Delete Cost" Margin="0 0 5 0" Click="btnDeleteCost_Click" IsEnabled="{Binding ElementName=lvCosts, Path=SelectedItem, Converter={StaticResource falseWhenNullConverter}}" >
                Delete Cost
            </Button>
        </StackPanel>
        <ctrls:SortableListView DockPanel.Dock="Top" x:Name="lvCosts" Margin="1" SelectionMode="Single" VerticalAlignment="Stretch" HorizontalAlignment="Stretch"

您的DockPanel包含：

StackPanel
a SortableListView和
另一个StackPanel

1＆amp; 2都停靠在顶部; 3停靠在底部。这意味着你中间没有任何东西，即。介于2和2之间3.重新排列元素的顺序以放置SortableListView第三个，并删除其DockPanel.Dock属性，以便占用剩余空间。

换句话说，而不是你现在拥有的：

<DockPanel>
    <StackPanel DockPanel.Dock="Top" ... >
    <ctrls:SortableListView DockPanel.Dock="Top" ... >
    <StackPanel DockPanel.Dock="Bottom" ... >
</DockPanel>

将其更改为：

<DockPanel>
    <StackPanel DockPanel.Dock="Top" ... >
    <StackPanel DockPanel.Dock="Bottom" ... >
    <ctrls:SortableListView ... >
</DockPanel>

WPF中的ListView未填充所有可用空间
