WPF，自定义的UserControl怎么绑定属性？

<UserControl x:Class="WPF熊俊.UserControl1"

             xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

             xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

             xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" 

             xmlns:d="http://schemas.microsoft.com/expression/blend/2008" 

             mc:Ignorable="d" 

             d:DesignHeight="300" d:DesignWidth="300">

    <Grid>

        

    </Grid>

</UserControl>

自定义的用户控件，我想把Grid的Background属性绑定到控件的Background属性上，该怎么写？
------解决方案--------------------
类似于     Background="{Binding Background, ElementName=this}"
