Question

我制作了一个列表，我的需求是能够在行中点击（触摸）用户，点击后我应该能够通过＆＃39; mid ＆＃ 39;对于事件，我隐藏在代码中，然后点击该记录。它有可能吗？

<Grid Grid.Row="1" Grid.ColumnSpan="2">
            <ScrollViewer VerticalScrollBarVisibility="Hidden" PanningMode="Both">
                <ItemsControl ItemsSource="{Binding Path=NextMeetingList}">
                    <ItemsControl.ItemTemplate>
                        <DataTemplate>
                            <StackPanel Grid.Column="0" Grid.Row="0">                                    
                                <Border Grid.Column="0" Grid.Row="0" Margin="10" Height="60" Background="GhostWhite" CornerRadius="3" BorderBrush="{Binding BorderColor}" BorderThickness="0,8,0,0">
                                    <Grid>
                                        <Grid.ColumnDefinitions>
                                            <ColumnDefinition Width="118"></ColumnDefinition>
                                            <ColumnDefinition Width="*"></ColumnDefinition>

Answer 1

一种可能的解决方案是将您的内容包装在一个不可见的按钮中，并将id或整个对象作为CommandParameter传递给ViewModel上的Command。

<Button Command="{Binding DataContext.MyCommmand, ElementName=mainGrid}"
    CommandParameter="{Binding}">
           <!-- Content -->
</Button>

Answer 2

通常，如果我想处理任何事情的Click事件，我只需使用Button并覆盖它的.Template。

<ItemsControl.ItemTemplate>
    <DataTemplate>
        <Button Template="{StaticResource ContentOnlyTemplate}"
                CommandParameter="{Binding mid}"
                Click/Command=...>
            <StackPanel Grid.Column="0" Grid.Row="0">                                    
                ...
            </StackPanel>
        </Button>
    </DataTemplate>
</ItemsControl>

WPF控件意味着“看起来很”，因此在这种情况下Button控件是理想的，因为它包含处理Click和/或Command / CommandParameter的功能。

单击ItemsControl的行并传递一个id
