这是我几天来一直试图解决的问题,但我还没有找到一个好的解决方案。
我有一个包含 StackPanel 的主 WPF 窗口。我还有一个名为“MessageManagement”的类,其中包含一个名为“MessagePreview”的自定义 WPF 控件列表。
消息预览

<Label Content="-ERROR-" Height="28" HorizontalAlignment="Left" Margin="2,1,0,0" Name="senderLabel" VerticalAlignment="Top" Foreground="#FF0000B4" Grid.RowSpan="2" />
<Label Content="-ERROR-" Height="33" HorizontalAlignment="Left" Name="previewLabel" VerticalAlignment="Top" Margin="-1,17,0,0" Grid.RowSpan="3" />
<Label Content="-Error-" Grid.Row="1" Height="28" HorizontalAlignment="Left" Margin="0,16,6,0" Name="timeLabel" VerticalAlignment="Top" Grid.RowSpan="2" Width="196" />
</Grid>
<Grid Name="grid3">
<Grid.RowDefinitions>
<RowDefinition Height="29*" />
<RowDefinition Height="27*" />
</Grid.RowDefinitions>
<Image Height="38" HorizontalAlignment="Center" Margin="3,0,6,20" Name="image1" Stretch="Fill" VerticalAlignment="Bottom" Width="41" Source="/FinalYearProject;component/Images/twitter-bird-light-bgs.png" Grid.RowSpan="2" />
<CheckBox Height="16" Margin="15,0,22,6" Name="checkBox" VerticalAlignment="Bottom" Grid.Row="1" IsChecked="False" />
</Grid>
</Grid>
消息管理
List<MessagePreview> unread = new List<MessagePreview>();
public bool messagesLocked()
{
foreach (MessagePreview m in unread)
{
if ((bool)m.checkBox.IsChecked)
return true;
}
return false;
}
主窗口 C#
MessageManagement messageManagement;
MessagesPanel1 是 MainWindow 内的空白 StackPanel
if (!messageManagement.messagesLocked())
{
foreach (Message m in messageManagement.getListOfMessages()
{
MessagesPanel1.Children.Add(m)
}
}
当您将自定义控件添加到 StackPanel 时,它会创建原始控件的副本,这意味着更改 StackPanel 中控件的值不会影响我的 MessageManagement List 中的控件。
有没有办法可以引用我的原始控件,以便它们一起更改?我查看了 DataBinding,但我不确定这是否是正确的区域。
