我有意見列表的ListView控件:出現MenuFlyout在ListView:元素已經被點擊了哪個
public class Comment
{
public Comment(String id, String user, String text, String date_time)
{
this.Id = id;
this.User = user;
this.Text = text;
this.DateTime = date_time;
}
public string Id { get; private set; }
public string User { get; private set; }
public string Text { get; private set; }
public string DateTime { get; private set; }
}
彈出菜單:
<ListView ItemsSource="{Binding Comments}">
<ListView.ItemTemplate>
<DataTemplate>
<Border Background="{Binding User, Converter={StaticResource UsernameToBackgroundColorConverter}}"
Margin="0,5"
HorizontalAlignment="Stretch"
FlyoutBase.AttachedFlyout="{StaticResource FlyoutBase1}"
Holding="BorderCommento_Holding">
<StackPanel>
<Grid Margin="5">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*" />
<ColumnDefinition Width="Auto" />
</Grid.ColumnDefinitions>
<TextBlock Text="{Binding User}"
FontSize="20"
Grid.Column="0"
FontWeight="Bold"
Style="{ThemeResource ListViewItemSubheaderTextBlockStyle}"/>
<TextBlock HorizontalAlignment="Right"
Text="{Binding DateTime}"
FontSize="20"
Grid.Column="1"
Style="{ThemeResource ListViewItemSubheaderTextBlockStyle}"/>
</Grid>
<TextBlock Margin="5,0,5,5"
Text="{Binding Text}"
FontSize="20"
TextWrapping="Wrap"/>
</StackPanel>
</Border>
</DataTemplate>
</ListView.ItemTemplate>
</ListView>
評論類當持有評論時在Page.Resources中定義:
<Page.Resources>
<MenuFlyout x:Name="flyout1" x:Key="FlyoutBase1">
<MenuFlyoutItem x:Name="ReportCommentFlyout"
Text="{Binding User, Converter={StaticResource ReportOrDeleteComment}}"
Click="ReportCommentFlyout_Click"/>
</MenuFlyout>
</Page.Resources>
現在,在ReportCommentFlyout_Click中,我需要知道正在報告/刪除的評論ID。 我該怎麼辦?
我已經試過
string CommentId = ((Comment)e.OriginalSource).Id;
但應用程序崩潰...
完美!它工作,謝謝 –
