我该如何修改以下代码实现，我按用户控件的最大化按钮时，用户控件占满整个主窗口，点击最小化按钮时回归原来的大小；
遇到的问题：点击最大化按钮，用户控件只能在网格grid里面最大化，无法突破网格，这该如何解决呀
用户控件的xmal代码如下：

MainWindow窗口添加用户控件的xaml代码：
Height="760" Width="1360" WindowStyle="None" ResizeMode="CanMinimize" WindowStartupLocation="CenterScreen" Loaded="Window_Loaded">
Grid.RowDefinitions>
<RowDefinition Height="auto"></RowDefinition>
<RowDefinition Height="*"></RowDefinition>
</Grid.RowDefinitions>
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="auto"></ColumnDefinition>
<ColumnDefinition Width="*"></ColumnDefinition>
</Grid.ColumnDefinitions>
<Grid Grid.Row="0" Grid.Column="2" Margin="0,0,1,1">
<local:LineChart_UserControl x:Name="LeftOutSideMargin"></local:LineChart_UserControl>
</Grid>
主窗口的后台代码中设置了主窗口的大小：
// 窗口工作区域大小
this.Height = SystemParameters.WorkArea.Height-20;
this.Width = SystemParameters.WorkArea.Width-20;
