小编ies*_*ras的帖子

美好时光.我在WPF中遇到数据绑定问题.如果我使用绑定:

<TextBlock Text="{Binding Key}" TextTrimming="CharacterEllipsis" 
MaxWidth="{Binding ActualWidth, RelativeSource={RelativeSource 
AncestorType={x:Type Expander}}, Converter={StaticResource string_cutter_width}}"/>

在下面的代码中,我Markup.IStyle.Connector.Connect在某些计算机上出错.我不明白为什么.如果你遇到这种行为或对此有一些想法.请分享.

            <DataGridTemplateColumn Header="{x:Static res:Resources.status_col_header}" Width="1*">
                <DataGridTemplateColumn.CellTemplate>
                    <DataTemplate>
                        <DataTemplate.Resources>
                            <local:Localizer2 x:Key="Localizer2" />
                        </DataTemplate.Resources>
                        <Expander Header="{Binding status.Text, Converter={StaticResource Localizer2}}" MouseEnter="Expander_MouseEnter" Tag="{Binding}">

请帮助我弄清楚如何在 WPF 的 DataGrid 中使用 ComboBoxColumn。我正在尝试创建一个设备列表，其中每个设备在“日志”字段中都有动态状态列表。

<DataGrid AutoGenerateColumns="False" Margin="12,6,12,12" Name="dataGrid1" Grid.Row="1"  SelectionUnit="FullRow">
    <DataGrid.Columns>
            ...
         <DataGridComboBoxColumn Header="Log" 
                                 ItemsSource="{Binding log, RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type local:Device}}}"/>
    </DataGrid.Columns>
</DataGrid>

public partial class MainWindow : Window
{
    public ObservableCollection<Device> devices;
    ...
}

public MainWindow() 
{
    ...
    dataGrid1.ItemSource = devices;
}

public class Device : INotifyPropertyChanged
{
    public event PropertyChangedEventHandler PropertyChanged;
    private void OnPropertyChanged(string propertyName)
    {
        if (PropertyChanged != null)
            PropertyChanged(this, new PropertyChangedEventArgs(propertyName));
    }
    public Device() {log = new ObservableCollection<string>();}
    ...
    private ObservableCollection<string> _log;
    public ObservableCollection<string> log …
