问题描述

我有以下代码

行的数据模板

<!-- Template for each item in ListView -->
    <DataTemplate x:Key="ItemTemplate">
        <Grid>                                
            <Grid.ColumnDefinitions>                    
                <ColumnDefinition Width="25"/>
                <ColumnDefinition Width="90"/>
                <ColumnDefinition Width="325"/>
                <ColumnDefinition Width="100"/>
                <ColumnDefinition Width="{Binding RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type l:ItemsView}}, Path=ParentColumnWidth}"/>
                <ColumnDefinition Width="100"/>
                <ColumnDefinition Width="100"/>                    
            </Grid.ColumnDefinitions>
            <CheckBox Grid.Column="0" x:Name="Statement" IsChecked="{Binding Path=statement}" Foreground="{StaticResource CustomWhite}" VerticalAlignment="Center" Style="{StaticResource SelectionCheckBox}"/>
            <TextBlock Grid.Column="1" Text="{Binding Path=idate, StringFormat=d MMM yy}" FontSize="15" Foreground="{StaticResource CustomWhite}"/>
            <TextBlock Grid.Column="2" Text="{Binding Path=fullcomment}" FontSize="15" Foreground="{StaticResource CustomWhite}"/>
            <TextBlock Grid.Column="3" Text="{Binding Path=amount, StringFormat={}{0:N2}}" FontSize="15" Foreground="{Binding Converter={StaticResource GetColourConverterItemAmount}}" TextAlignment="Right" Padding="0,0,25,0"/>
            <TextBlock Grid.Column="4" Text="{Binding Path=acc}"  FontSize="15" Foreground="{StaticResource CustomWhite}"/>
            <TextBlock Grid.Column="5" Text="{Binding Path=source}" FontSize="15" Foreground="{StaticResource CustomWhite}"/>
            <TextBlock Grid.Column="6" Text="{Binding Path=transfer}" FontSize="15" Foreground="{StaticResource CustomWhite}"/>                
        </Grid>
        <DataTemplate.Triggers>
            <DataTrigger Binding="{Binding Path=statement}" Value="{x:Null}">
                <Setter TargetName="Statement" Property="IsEnabled" Value="False"/>
            </DataTrigger>
        </DataTemplate.Triggers>
    </DataTemplate>

ListView的样式-使用上面的DataTemplate

Style for ListView - using above DataTemplate

<!-- ListView template -->
    <Style x:Key="HistoryListView" TargetType="{x:Type ListView}">
        <Setter Property="ItemTemplate" Value="{StaticResource ItemTemplate}"/>
        <Setter Property="Background" Value="{StaticResource CustomBackground}"/>
        <Setter Property="BorderThickness" Value="0"/>
        <Setter Property="HorizontalAlignment" Value="Left"/>
        <Setter Property="Margin" Value="10,10,10,10"/>
        <Setter Property="VerticalAlignment" Value="Top"/>
        <Setter Property="Padding" Value="0,0,50,0"/>
        <Setter Property="FocusVisualStyle" Value="{x:Null}"/>
        <Setter Property="ScrollViewer.HorizontalScrollBarVisibility" Value="Disabled"/>            
        <Style.Resources>
            <!-- Makes selection stay when focus lost (for context menu)-->
            <SolidColorBrush x:Key="{x:Static SystemColors.ControlBrushKey}" Color="{StaticResource CustomLightHighlightC}"/>
        </Style.Resources>
    </Style>        

    <Style x:Key="HistoryContainerStyle" TargetType="ListViewItem">
        <Setter Property="ContextMenu" Value="{StaticResource ItemMenu}"/>
        <Setter Property="FocusVisualStyle" Value="{x:Null}"/>
    </Style>

我的ListView定义为

And my ListView is defined as

<ListView x:Name="lstHistory" ItemsSource="{Binding Path=Items}" Style="{StaticResource HistoryListView}" MouseDoubleClick="lvShowItem" SelectionChanged="lstSelectionChanged" ItemContainerStyle="{StaticResource HistoryContainerStyle}"/>

这将产生一个正是我想要的ListView-除了我没有标题外-理想情况下，我会像可排序的标题我还想尽可能在​​样式中添加标题，以便在其他模块中重复使用。

This produces a ListView that is exactly what I want - except I have no headers - and ideally I would like sortable headers. I would also like to 'add' the headers in the Style if possible so I can reuse it in other modules.

Any help appreciated Thanks Andy

找到了答案。

定义ListView及其关联元素：

            </Setter.Value>
        </Setter>
    </Style>

并将模板定义为GridView：

And define template as a GridView:

        <!-- Template for each item in ListView -->
    <GridView x:Key="ItemView">
        <GridViewColumn Header="" Width="25">
            <GridViewColumn.CellTemplate>
                <DataTemplate>
                    <CheckBox x:Name="Statement" IsChecked="{Binding Path=statement}" Foreground="{StaticResource CustomWhite}" VerticalAlignment="Center" Style="{StaticResource SelectionCheckBox}"/>
                    <DataTemplate.Triggers>
                        <DataTrigger Binding="{Binding Path=statement}" Value="{x:Null}">
                            <Setter TargetName="Statement" Property="IsEnabled" Value="False"/>
                        </DataTrigger>
                    </DataTemplate.Triggers>
                </DataTemplate>
            </GridViewColumn.CellTemplate>
        </GridViewColumn>
        <GridViewColumn Header="Date" Width="90">
            <GridViewColumn.CellTemplate>
                <DataTemplate>
                    <TextBlock Text="{Binding Path=idate, StringFormat=d MMM yy}" Foreground="{StaticResource CustomWhite}"/>
                </DataTemplate>
            </GridViewColumn.CellTemplate>
        </GridViewColumn>
        <GridViewColumn Header="Comment" Width="325">
            <GridViewColumn.CellTemplate>
                <DataTemplate>
                    <TextBlock Text="{Binding Path=fullcomment}" Foreground="{StaticResource CustomWhite}"/>
                </DataTemplate>
            </GridViewColumn.CellTemplate>
        </GridViewColumn>
        <GridViewColumn Header="Amount" Width="100">
            <GridViewColumn.CellTemplate>
                <DataTemplate>
                    <TextBlock Text="{Binding Path=amount, StringFormat={}{0:N2}}" Foreground="{Binding Converter={StaticResource GetColourConverterItemAmount}}" TextAlignment="Right" Padding="0,0,25,0"/>
                </DataTemplate>                    
            </GridViewColumn.CellTemplate>
        </GridViewColumn>
        <GridViewColumn Header="Account" Width="{Binding RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type l:ItemsView}}, Path=ParentColumnWidth}">
            <GridViewColumn.CellTemplate>
                <DataTemplate>
                    <TextBlock Text="{Binding Path=acc}" Foreground="{StaticResource CustomWhite}"/>
                </DataTemplate>
            </GridViewColumn.CellTemplate>
        </GridViewColumn>
        <GridViewColumn Header="Source" Width="100">
            <GridViewColumn.CellTemplate>
                <DataTemplate>
                    <TextBlock Text="{Binding Path=source}" Foreground="{StaticResource CustomWhite}"/>
                </DataTemplate>
            </GridViewColumn.CellTemplate>
        </GridViewColumn>
        <GridViewColumn Header="Transfer" Width="100">
            <GridViewColumn.CellTemplate>
                <DataTemplate>
                    <TextBlock Text="{Binding Path=transfer}" Foreground="{StaticResource CustomWhite}"/>
                </DataTemplate>
            </GridViewColumn.CellTemplate>
        </GridViewColumn>
    </GridView>

仍在进行排序。将更新。

Still working on sorting. Will update.
