DataTemplate中grid的宽度问题

[wxcnl]

看下面代码,listbox引用的数据模板,并且邦定了一个集合数据,现在想实现点击每一个item的内容触发command,问题是listbox item的宽度为自动伸展的,也就是100%了,但是grid的宽度却是随着文本的宽度的变化而变化,也就是说grid的宽度和文本的宽度一样,后果是点击文本内容才能触发command,但我现在需要点击整个item的内容也要触发command,也就是说如何让grid或者stackpanel的宽度和listbox item的宽度一样长?或者说让他们伸展到100%?

<DataTemplate x:Key="RecentProjectTemplate">
            <Grid Margin="0,10,0,0" HorizontalAlignment="Stretch" VerticalAlignment="Stretch" Width="auto">
                <Grid.ColumnDefinitions>
                    <ColumnDefinition Width="25" />
                    <ColumnDefinition Width="*" />                    
                </Grid.ColumnDefinitions>
                <Grid.RowDefinitions>
                    <RowDefinition ></RowDefinition>
                </Grid.RowDefinitions>                <StackPanel Grid.Column="1" Grid.Row="0" Background="Red" Margin="0,0,0,0">                   
                    <StackPanel.InputBindings>
                        <MouseBinding Command="{Binding DataContext.RecentProjectsCommand, RelativeSource={RelativeSource AncestorType=ListBox}}" MouseAction="LeftClick" />
                    </StackPanel.InputBindings>
                    <TextBlock Foreground="Black" Text="{Binding}" Margin="20,0,0,0">                    
                </TextBlock>
                </StackPanel>                              
            </Grid>           
        </DataTemplate>

<ListBox BorderThickness="0" Margin="0,0,0,0" ItemTemplate="{StaticResource RecentProjectTemplate}" ItemsSource="{Binding RecentProjects}">

模板里面修改你的大小啊

[Bonjour-你好]

ListBox中添加 HorizontalContentAlignment="Stretch" 试试

不行啊!之前都尝试过了

<ListBox.ItemContainerStyle> <Style TargetType="ListBoxItem"> <Setter Property="HorizontalContentAlignment" Value="Stretch" />
