[WPF] 仿Windows文件管理器,鼠标拖动选择ListBox列表项+自动分栏Canvas面板

效果图:

 

 

鼠标拖动选择ListBoxItem的单独演示:

使用方式:修改ListBox模板,使用自定义面板ListBoxDragSelectViewer替代ScrollViewer;ListBoxDragSelectViewer里面封装了ScrollViewer;

<ControlTemplate TargetType="{x:Type ListBox}">
    <pp:ListBoxDragSelectViewer Background="{TemplateBinding Background}" ScrollViewer.HorizontalScrollBarVisibility="{TemplateBinding ScrollViewer.HorizontalScrollBarVisibility}" ScrollViewer.CanContentScroll="False">
        <ItemsPresenter />
    </pp:ListBoxDragSelectViewer>
</ControlTemplate>

 

自动分栏效果单独演示:

 

使用方式:像ListBox一样绑定ItemsSource以及修改ItemTemplate;行列将根据实际大小分成接近正方形的小格;子项支持鼠标拖动,做了自动吸附效果;目前控件分割线效果还不理想;

<pp:AutoGridCanvas x:Name="agc" Margin="5" Background="LightGray" StrokeThickness="1" Stroke="Black">
    <pp:AutoGridCanvas.ItemTemplate>
        <DataTemplate>
            <Border Background="LightCyan">
                <TextBlock VerticalAlignment="Center" HorizontalAlignment="Center" FontSize="36" Text="{Binding}" />
            </Border>
        </DataTemplate>
    </pp:AutoGridCanvas.ItemTemplate>
</pp:AutoGridCanvas>
