c# - 从 Xceed PropertyGrid 中的只读单元格复制文本

Question

我将只读属性绑定到 PropertyGrid，我希望用户能够从单元格中选择和复制文本。我需要使用不同的属性吗？如果是这样，我应该使用哪个？或者也许有不同的解决方案？

谢谢，

请不要在属性上使用 [ReadOnly(true)]。但是可以通过将其设置为 ReadOnly TextBox 来限制在 xceed 属性网格右侧编辑属性的值，如下所示：

.xaml：

<xctk:PropertyGrid x:Name="MyPrpGrid" HorizontalAlignment="Stretch"  VerticalAlignment="Stretch"
FontWeight="ExtraBold" ShowSearchBox="False" ShowSortOptions="False"
SelectedObject="{Binding BindedPropName, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}"
Background="#FF4A5D80" Foreground="White" >

<xctk:PropertyGrid.EditorDefinitions>
    <!-- For Id, Text and Type fields at left-side in the xceed property grid, replace right-side value area with ReadOnly TextBox -->
    <xctk:EditorDefinition>
        <xctk:EditorDefinition.PropertiesDefinitions>
            <xctk:PropertyDefinition Name="Id"/>     <!-- BindedPropName.Id -->
            <xctk:PropertyDefinition Name="Text" />  <!-- BindedPropName.Text -->
            <xctk:PropertyDefinition Name="Type" />  <!-- BindedPropName.Type -->
        </xctk:EditorDefinition.PropertiesDefinitions>
        <xctk:EditorDefinition.EditorTemplate>
                <DataTemplate>
                    <!-- Binded Value is a DependencyProperty which is defined in view model -->
                    <TextBox IsReadOnly="True" Text="{Binding Value}" BorderThickness="0"/>
                </DataTemplate>
        </xctk:EditorDefinition.EditorTemplate>
    </xctk:EditorDefinition>
</xctk:PropertyGrid.EditorDefinitions>

</xctk:PropertyGrid>

MyViewModel.cs 应该从 DependencyObject 派生。

MyViewModel.cs：

    public static readonly DependencyProperty ValueProperty = DependencyProperty.Register("Value", typeof(string), typeof(MyViewModel),
                                                                                      new FrameworkPropertyMetadata(null, FrameworkPropertyMetadataOptions.BindsTwoWayByDefault));
public string Value
{
    get { return (string)GetValue(ValueProperty); } // GetValue() is from derived DependencyObject class
    set { SetValue(ValueProperty, value); }         // SetValue() is from derived DependencyObject class
}
