C# bindinglist中的对象属性更改时datagrid单元格不更新

我有一个带有datagrid的WPF应用程序，其ItemsSource是一个BindingList。当我更改BindingList中的对象时，datagrid不会被更新。当我修改BindingList中的对象时，如何确保datagrid更新

以下是XAML：

<DataGrid CanUserAddRows="False" AutoGenerateColumns="False" HorizontalAlignment="Stretch" Name="dgLocalPlugins" VerticalAlignment="Stretch" SelectionMode="Single" AlternatingRowBackground="#CDEBEBEB" Margin="5,85,5,143" Width="Auto" SelectionChanged="dgLocalPlugins_SelectionChanged">
    <DataGrid.Columns>
        <DataGridCheckBoxColumn Header="Enabled" Binding="{Binding Path=Enabled}" Width="55" >
            <DataGridCheckBoxColumn.CellStyle>
                <Style>
                    <EventSetter Event="CheckBox.Checked" Handler="OnChecked"/>
                    <EventSetter Event="CheckBox.Unchecked" Handler="OnUnchecked"/>
                </Style>
            </DataGridCheckBoxColumn.CellStyle>
        </DataGridCheckBoxColumn>
        <DataGridTextColumn Header="Plugin" Binding="{Binding Path=Type}" IsReadOnly="True" Width="*" />
        <DataGridTextColumn Header="Status" Binding="{Binding Path=Status}" IsReadOnly="True" Width="*" />
    </DataGrid.Columns>
</DataGrid>

现在，当我修改一个PluginDescription对象的属性时，DataGrid并没有被更新。我认为在PluginDescription类上实现INotifyPropertyChange接口就是我所需要的。是否需要执行其他操作？

必须为

PropertyChanged

事件提供属性的准确名称。在您的代码中，存在一些不匹配的情况：

WikiUrl

属性使用

“Wiki”

引发

PropertyChanged

事件，而

Status

属性使用

“Statua”

。试着先把它们修好

---

如果仍然不起作用，请指定要更改的属性好吗？

您已经找到了错误的原因。但为了避免将来出现此类问题，我建议在可接受的情况下使用Lambda表达式

请注意，这会带来一些性能损失，但有人在这里描述了这一点：

但属性更改通知通常很少触发，因此这并不是一个真正的问题。然而，这取决于你的使用

谢谢。真不敢相信我漏掉了那个打字错误。现在似乎正在按预期工作。
