WPF 列表框包装

Question

我有一个列表框，我在其中使用 ListBox.ItemsPanel - WrapPanel。

<ListBox ItemsSource="{Binding Path=Applets}" Margin="10,92,10,10" ScrollViewer.HorizontalScrollBarVisibility="Disabled" >

        <ListBox.ItemsPanel>
            <ItemsPanelTemplate>

                <WrapPanel Orientation="Vertical" IsItemsHost="True">

                </WrapPanel>
            </ItemsPanelTemplate>
        </ListBox.ItemsPanel>



        <ListBox.ItemTemplate>...

我试图让 wrappanel 具有这样一种行为，即当宽度变宽时，项目向右填充，并在窗口变窄时根据需要进行包裹。我玩过它，但正确的组合让我望而却步。有人有建议吗？

我的下一个目标是能够重新排序/排序项目并更新渲染。

TIA

Answer 1

I am trying to have the wrappanel have a behavior such that the items fill in to the right as the width is made wider and wrap as needed when the window is made narrower. I have played with it but the correct combination eludes me. Does anyone have a suggestion?

您拥有的代码几乎正确，只需更改 Orientation至 Horizontal它应该像你描述的那样工作

My next goal would be able to reorder/ sort the items and have the render update.

你不必为此做任何特别的事情，这是 ListBox 的正常行为。 .只需更改排序顺序(使用 ICollectionView.SortDescriptions )，UI 将反射(reflect)更改
