Question

我有一个带有数据模板的清单, 显示文本和旁边的“ x” 按钮。我希望在极右显示“ X” btn, 所以它们都出现在同一位置。我使用的 XML 是 :

<ListBox Name="seiveListBox" ItemsSource="{Binding}" MinWidth="80" Height="120" ScrollViewer.VerticalScrollBarVisibility="Visible" >
                                <ListBox.ItemTemplate>
                                    <DataTemplate>
                                        <StackPanel Orientation="Horizontal">
                                            <TextBlock Text="{Binding}" />
                                            <Button Name="delSeiveFromListBtn" Content="X" ToolTip="Delete" Margin="8, 0, 0, 0" Click="delSeiveFromListBtn_Click"></Button>
                                        </StackPanel>
                                    </DataTemplate>
                                </ListBox.ItemTemplate>
                            </ListBox>

我试图添加StackPanel的网格内盘,但是没有成功。

我如何设计它或对齐列表中的“x”在每一个项目上处于极右位置。

Answer 1

在这里,我把它,使用网格如下方式:

<ListBox ItemsSource="{Binding Items}"
          Width="200" HorizontalContentAlignment="Stretch">
    <ListBox.ItemTemplate>
        <DataTemplate>
            <Grid>
                <Grid.ColumnDefinitions>
                    <ColumnDefinition Width="*"/>
                    <ColumnDefinition Width="Auto"/>
                </Grid.ColumnDefinitions>
                <TextBlock Grid.Column="0" Text="{Binding Data}"></TextBlock>
                <Button Grid.Column="1" Content="x"></Button>
            </Grid>
        </DataTemplate>
    </ListBox.ItemTemplate>
</ListBox>

If your item are supposed to be buttons then you have to specifiy HorizontalContentAlignment="Stretch". Here is the template I use for buttons with a cross on the right side:

    <DataTemplate x:Key="DeletableButtonCommandTemplate">
    <Button Command="{Binding}" Margin="0,1" HorizontalContentAlignment="Stretch">
        <Grid HorizontalAlignment="Stretch">
            <Grid.ColumnDefinitions>
                <ColumnDefinition Width="*"/>
                <ColumnDefinition Width="18"/>
            </Grid.ColumnDefinitions>
            <TextBlock Text="{Binding Caption}" HorizontalAlignment="Center" Grid.Column="0"></TextBlock>
            <shared:CrossButton Width="12" Height="12" Grid.Column="1"
                                cal:Message.Attach="[Event Click]=[DeleteCommandSource($Datacontext)]"
                                Visibility="{Binding Path=AssociatedObject.Owner, Converter={sharedConv:NotNullToVisibleConverter} }"  />
        </Grid>
    </Button>
</DataTemplate>
