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 …

我在 WPF 中创建了一个自定义组合框

<!-- Combobox template -->
    <ControlTemplate x:Key="CustomComboBoxToggleButton" TargetType="ToggleButton">
        <Grid>
            <Grid.ColumnDefinitions>
                <ColumnDefinition/>
                <ColumnDefinition Width="20"/>
            </Grid.ColumnDefinitions>
            <Border x:Name="Border" Grid.ColumnSpan="2" CornerRadius="3" Background="{StaticResource CustomDarkBlue}" BorderBrush="{StaticResource CustomWhite}" BorderThickness="2"/>
            <Border x:Name="Border2" Grid.Column="0" CornerRadius="3,0,0,3" Margin="1" Background="{StaticResource CustomBackground}" BorderBrush="{StaticResource CustomWhite}" BorderThickness="1,1,2,1"/>
            <Path x:Name="Arrow" Grid.Column="1" Fill="{StaticResource CustomGlyph}" HorizontalAlignment="Center" VerticalAlignment="Center" Data="M 0 0 L 4 4 L 8 0 Z"/>
        </Grid>
        <ControlTemplate.Triggers>
            <Trigger Property="ToggleButton.IsMouseOver" Value="True">
                <Setter TargetName="Border" Property="Background" Value="{StaticResource CustomDarkBlue}"/>
            </Trigger>
            <Trigger Property="ToggleButton.IsChecked" Value="True">
                <Setter TargetName="Border" Property="Background" Value="{StaticResource CustomDarkBlue}"/>
            </Trigger>
            <Trigger Property="IsEnabled" Value="False">                    
                <Setter TargetName="Border" Property="BorderBrush" Value="{StaticResource CustomGray}"/> …

我实际上想UPDATE在Access数据库（通过ADO.NET）中的表上运行命令，但我希望它向后运行（即从最后一条记录到第一个记录），以避免重复相同的记录'ID'。

我尝试添加，& " ORDER BY ID DESC;"但这会引发错误，因为不允许这样做。

救命！

谢谢安迪

Dim dsxcmd As OleDbCommand

strSelect = "UPDATE Items SET ID=ID+1 WHERE ID>=" & lInsert.ToString 
dsxcmd = New OleDbCommand(strSelect, cn)
dsxcmd.ExecuteNonQuery()
dsxcmd.Dispose()
