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 Width="430" Height="500" Background="White" >

xaml

　　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
