我在WPF页面上有一个标签LabelMessage
和一个ComboBox ComboBoxSelection
。这是XAML:
<Label Name="LabelMessage" Content="" Margin="0,20" HorizontalAlignment="Stretch" VerticalAlignment="Center" />
<ComboBox x:Name="ComboBoxSelection" SelectionChanged="OnComboBoxSelectionChanged" Height="20" Margin="112,10,0,0" HorizontalAlignment="Stretch" VerticalAlignment="Top" IsEnabled="True" >
<ComboBoxItem Content="North" />
<ComboBoxItem Content="South" />
<ComboBoxItem Content="East" />
<ComboBoxItem Content="West" />
</ComboBox>
这是C#:
private void OnComboBoxSelectionChanged(object sender, SelectionChangedEventArgs e)
{
LabelMessage.Content = ComboBoxSelection.Text;
}
标签显示ComboBox的之前内容,而不是当前选择。谢谢,如果我选择North
然后选择East
,则标签会显示North
。如果我然后选择South
,则标签会显示East
。
可能导致此问题的原因,我该如何解决?
感谢。
