【原创】DevExpress控件GridControl中的布局详解

在进行DevExpress控件GridControl的使用时，因控件的灵活性，所以用户会经常进行拖动控件的列，以达到自己满意的样式，

但下次再打开时系统就会重新还原到原有的布局风格，为了能够保持用户之前设置的风格，下次再打开时依然保持原有的风格。

在gridView中有两个方法：SaveLayoutToXml（保存布局）,RestoreLayoutFromXml（恢复布局)

 以下是具体的代码：

  
    

   
      
   
     private
   
      
   
     string
   
      systempath 
   
     =
   
      
   
     "
   
     C:\\Program Files\\
   
     "
   
     ;
 
   
     ///
   
      
   
     <summary>
