DevExpress组件之——ChartControl组件打印

        由于项目中需要将ChartControl中的图表打印出来，自带的只有个预览方法ShowPrintPreview()，经过资料查找，并对DevExpress打印进行了一些整理，现把具体思路贴供大家参考。

 

实现打印需要用到的主要类有PrintingSystem、XtraPageSettings、PrintableComponentLink 。
1、PrintingSystem类

      该类负责提供生成报表的一些方法，还提供了对页面进行设置和打印报表的一些函数，这个类的属性包含了访问其他管理报表的对象，如Document类，BrickGraphics类(在报表上进行画图的类)。

2、XtraPageSettings类(提供对打印页面进行设置的操作)

3、PrintableComponentLink类

      该类对实现DevExpress.XtraPrinting.IPrintable接口的所有控件进行打印，它提供了一些基本的生成和打印报表的功能。在生成报表以后可以通过PrintingSystem将报表打印出来。

 4、代码实现：

 5、通过以上这两个类就能完全实现各种控件的打印了，只要一个控件实现了DevExpress.XtraPrinting.IPrintable这个接口就能够对该控件进行打印，如GridControl,CharControl等。
