搜索问题，发现答案都是如果使控件闪烁的答案，最后去stackflow找答案，如果希望鼠标进入就显示控件，可以使用Opacity属性控制显隐。

code:

<WrapPanel.Resources>
                                                <Style x:Key="WrapPanelStyle" TargetType="WrapPanel">
                                                    <Style.Setters>
                                                        <Setter Property="Opacity" Value="0"></Setter>
                                                    </Style.Setters>
                                                    <Style.Triggers>
                                                        <Trigger Property="IsMouseOver" Value="True">
                                                            <Setter Property="Opacity" Value="1"></Setter>
                                                        </Trigger>

                                                        <Trigger Property="IsMouseOver" Value="False">
                                                            <Setter Property="Opacity" Value="0"></Setter>
                                                        </Trigger>

                                                        <Trigger Property="IsFocused" Value="True">
                                                            <Setter Property="Background" Value="AliceBlue"></Setter>
                                                        </Trigger>
                                                    </Style.Triggers>
                                                </Style>
                                            </WrapPanel.Resources>
