找不到类型 'System.Windows.Controls.Grid' 的模板 属性 'Foreground'

Question

我正在尝试在选项卡控件的 ControlTemplate 触发器中添加 属性 'Foreground' :

                                <ControlTemplate.Triggers>
                                    <Trigger Property="IsSelected" Value="True">
                                        <Setter TargetName="Panel" Property="Background" Value="LightSkyBlue" />
                                    </Trigger>
                                    <Trigger Property="IsSelected" Value="False">
                                        <Setter TargetName="Panel" Property="Background" Value="Gray" />
                                        <Setter  Property="Foreground" TargetName="Panel" Value="White"/>
                                    </Trigger>
                                </ControlTemplate.Triggers>
                            </ControlTemplate>

Error Cannot find the Template Property 'Foreground' on the type 'System.Windows.Controls.Grid'.

这里有什么问题？

我通过添加修复了错误：

 <Setter Property="TextElement.Foreground" TargetName="Panel" Value="White"></Setter>

所以完整的代码将是：

                  <ControlTemplate.Triggers>
                            <Trigger Property="IsSelected" Value="True">
                                <Setter TargetName="Panel" Property="Background" Value="LightSkyBlue" />
                            </Trigger>
                            <Trigger Property="IsSelected" Value="False">
                                <Setter TargetName="Panel" Property="Background" Value="Gray" />
 <Setter Property="TextElement.Foreground" TargetName="Panel" Value="White"/>

                            </Trigger>
                        </ControlTemplate.Triggers>
                    </ControlTemplate>
