简述：

　　手工以原生Grid的方式，自定义了一个仿弹窗效果，优点可以自定义，缺点需要自己实现以及维护整个弹窗的效果 

效果图：

　　

思路：

　　直接画好页面，控制它的展示消失即可

代码：

　　1.xaml的弹框，下面的按钮是自定义的样式

<!--确认xlsx的模态框自定义ConfirmedModalBox-->
        <Border x:Name="incConfirmedModalBox"  Grid.Column="1" Margin="-160,-80,30,10"  Width="430" Height="500"  BorderBrush="#000" BorderThickness="1" Background="White" Visibility="Collapsed">
            <!--Margin="6,6,6,6"-->

                </Grid>
            </Grid>
        </Border>

 　　2.cs后端的控制

 incConfirmedModalBox.Visibility = Visibility.Visible;

　　3.业务代码就不做展示了，就是把此控件放到xaml末尾，根据Grid布局定位到页面中间，控制它展示隐藏即可，他们确定取消按钮正常调用后台逻辑代码即可，调用完成之后将incConfirmeDModalBox隐藏，维护关联逻辑

备注：

　　本来这块想要讲很多的，但是涉及到没有准备现成的Demo，之前编写的业务不便公开，草草收尾了，下次重新补上一份
