我用 DataGrid 和 TextBox 创建窗口：

    <DataGrid CanUserAddRows="False" ItemsSource="{Binding Path=CRow}" HorizontalAlignment="Left" Height="505" Margin="0,46,0,0" Grid.Row="0" VerticalAlignment="Top" Width="1152" Name="MainDataGrid" CellEditEnding="MainDataGridCellEditEnding" SelectedCellsChanged="MainDataGridSelectedCellsChanged" AutoGenerateColumns="False" PreviewMouseLeftButtonUp="MainDataGrid_PreviewMouseLeftButtonUp">
        <DataGrid.Resources>
            <ContextMenu x:Key="CellContextMenu">
                <MenuItem Name="DataGridUndoMenuItem" Command="Undo" Header="Undo">
                    <MenuItem.Icon>
                        <Image Source="Images/Undo.png" />

代码通过 ObservableCollection 填充一个表：

MainDataGrid.ItemsSource = Rows; //ObservableCollection<CRow> Rows

但是当我更改 TranslationTextBox 中的文本时，只有在我开始编辑单元格时才会出现 DataGrid 更改。如何解决？

Crow代码：

public enum RowSearchMode { IgnoreCase, MatchCase, Regex }
public class CRow : INotifyPropertyChanged
{
    public int Number { get; set; }
    public string Tags { get; set; }
    public string ID { get; set; }
    public string OriginalText { get; set; }
    public string Translation { get; set; }

    public CRow(int iNumber, string strID, string strOriginalText, string strTranslation)
    {
        Number = iNumber;
        ID = strID;
        OriginalText = strOriginalText;
        Translation = strTranslation;

        Tags = "";
    }

    public CRow():this(0,"","",""){}

    public event PropertyChangedEventHandler PropertyChanged;
    protected void RaisePropertyChanged(string strName)
    {
        if (PropertyChanged != null)
        {
            PropertyChanged(this, new PropertyChangedEventArgs(strName));
        }
    }

    public bool Contrains(string strText, RowSearchMode hMode = RowSearchMode.IgnoreCase)
    {
        switch (hMode)
        {
            case RowSearchMode.MatchCase:
                return ID.Contains(strText) || OriginalText.Contains(strText) || Translation.Contains(strText);
            case RowSearchMode.IgnoreCase:
                return ID.ToLower().Contains(strText.ToLower()) || OriginalText.ToLower().Contains(strText.ToLower()) || Translation.ToLower().Contains(strText.ToLower());
            case RowSearchMode.Regex:
                return Regex.IsMatch(ID, strText) || Regex.IsMatch(OriginalText, strText) || Regex.IsMatch(Translation, strText);
        }
        return false;
    }

    public void Replace(string strOldText, string strNewText, RowSearchMode hMode = RowSearchMode.IgnoreCase)
    {
        switch (hMode)
        {
            case RowSearchMode.MatchCase:
                ID = ID.Replace(strOldText, strNewText);
                Translation = Translation.Replace(strOldText, strNewText);
                OriginalText = OriginalText.Replace(strOldText, strNewText);
                break;
            case RowSearchMode.IgnoreCase:
                ID = ID.Replace(strOldText, strNewText);
                Translation = Translation.Replace(strOldText, strNewText);
                OriginalText = OriginalText.Replace(strOldText, strNewText);
                break;
            case RowSearchMode.Regex:
                var hRegex = new Regex(strOldText);
                ID = hRegex.Replace(ID, strNewText);
                Translation = hRegex.Replace(Translation, strNewText);
                OriginalText = hRegex.Replace(OriginalText, strNewText);
                break;
        }
    }
}

您必须像下面这样为您的属性提出属性更改，以便让 UI 知道它正在更改。

private string _translation;
public string Translation 
{ 
     get
     {
          return _translation;
     } 
     set
     {
         _translation = value;
        RaisePropertyChanged("Translation");
     }

}
