DevExpress GridControl使用教程：打印详解

通过几天的学习，终于对打印有了初步的认识，并实现了打印功能，下面将详细介绍下如何使用DevExpress下的打印功能。
首先要实现打印功能必须添加一个引用：DevExpress.XtraPrint
实现打印需要用到的主要的类：
1. public class PrintingSystem : Component, ISupportInitialize,IPrintingSystem,IAccessible,IExporter,IPrintingSystemContext
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）、XtraPageSettings类（提供对打印页面进行设置的操作）
2. public class PrintableComponentLink : Link
该类的功能是对实现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。
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等等，下面给出具体的实现方法：
public class PrintSettingController
{
PrintingSystem ps =  null ;
string formName =  null ;
 
         PrintableComponentLink link =  null ;
 
         string _PrintHeader =  null ;
/// <summary>
/// 打印时的标题
/// </summary>
public string PrintHeader
{
set
{
_PrintHeader = value;
}
}
 
         string _PrintFooter =  null ;
/// <summary>
/// 打印时页脚
/// </summary>
public string PrintFooter
{
set
{
_PrintFooter = value;
}
}
 
         bool _landScape;
/// <summary>
/// 页面横纵向
/// </summary>
public bool LandScape
{
set { _landScape = value; }
}
 
         System.Drawing.Printing.PaperKind _paperKind;
/// <summary>
/// 纸型
/// </summary>
public System.Drawing.Printing.PaperKind PaperKind
{
set { _paperKind = value; }
}
 
         /// <summary>
/// 打印控制器
/// </summary>
/// <param name="control">要打印的部件</param>
public PrintSettingController(IPrintable control)
{
if (control ==  null )  return ;
Control c = (Control)control;
formName = c.FindForm().GetType().FullName +  "." + c.Name;
ps =  new DevExpress.XtraPrinting.PrintingSystem();
link =  new DevExpress.XtraPrinting.PrintableComponentLink(ps);
ps.Links.Add(link);
link.Component = control;
}
 
         /// <summary>
/// 打印预览
/// </summary>
public void Preview()
{
try
{
if (DevExpress.XtraPrinting.PrintHelper.IsPrintingAvailable)
{
Cursor.Current = Cursors.AppStarting;
if (_PrintHeader !=  null )
{
PageHeaderFooter phf = link.PageHeaderFooter  as PageHeaderFooter;
 
                         //设置页眉
phf.Header.Content.Clear();
phf.Header.Content.AddRange( new string [] {  "" , _PrintHeader,  "" });
phf.Header.Font =  new System.Drawing.Font( "宋体" , 14, System.Drawing.FontStyle.Bold);
phf.Header.LineAlignment = BrickAlignment.Center;
 
                         //设置页脚
phf.Footer.Content.Clear();
phf.Footer.Content.AddRange( new string [] {  "" ,  "" , _PrintFooter });
phf.Footer.Font =  new System.Drawing.Font( "宋体" , 9, System.Drawing.FontStyle.Regular);
phf.Footer.LineAlignment = BrickAlignment.Center;
 
                     }
link.PaperKind = ps.PageSettings.PaperKind ;
link.Margins = ps.PageSettings.Margins;
link.Landscape = ps.PageSettings.Landscape;
link.CreateDocument();
 
//汉化
DevExpress.XtraPrinting.Localization.PreviewLocalizer.Active =  new Dxperience.LocalizationCHS.DxperienceXtraPrintingLocalizationCHS();
ps.PreviewFormEx.Show();
 
                 }
else
{
Cursor.Current = Cursors.Default;
MessageBox.Show( "打印机不可用 " ,  "提示" , MessageBoxButtons.OK, MessageBoxIcon.Information);
}
}
finally
{
Cursor.Current = Cursors.Default;
}
}
 
         /// <summary>
/// 打印
/// </summary>
public void Print()
{
try
{
if (DevExpress.XtraPrinting.PrintHelper.IsPrintingAvailable)
{
if (_PrintHeader !=  null )
{
PageHeaderFooter phf = link.PageHeaderFooter  as PageHeaderFooter;
 
                         //设置页眉
phf.Header.Content.Clear();
phf.Header.Content.AddRange( new string [] {  "" , _PrintHeader,  "" });
phf.Header.Font =  new System.Drawing.Font( "宋体" , 14, System.Drawing.FontStyle.Bold);
phf.Header.LineAlignment = BrickAlignment.Center;
 
                         //设置页脚
phf.Footer.Content.Clear();
phf.Footer.Content.AddRange( new string [] {  "" ,  "" , _PrintFooter });
phf.Footer.Font =  new System.Drawing.Font( "宋体" , 9, System.Drawing.FontStyle.Regular);
phf.Footer.LineAlignment = BrickAlignment.Center;
 
                     }
link.PaperKind = ps.PageSettings.PaperKind;
link.Margins = ps.PageSettings.Margins;
link.Landscape = ps.PageSettings.Landscape;
link.CreateDocument();
link.CreateDocument();
//汉化
DevExpress.XtraPrinting.Localization.PreviewLocalizer.Active =  new Dxperience.LocalizationCHS.DxperienceXtraPrintingLocalizationCHS();
ps.Print();
}
else
{
Cursor.Current = Cursors.Default;
MessageBox.Show( "打印机不可用 " ,  "提示" , MessageBoxButtons.OK, MessageBoxIcon.Information);
}
}
finally
{
}
}
 
         //获取页面设置信息
public void LoadPageSetting()
{
 
             System.Drawing.Printing.Margins margins =  new System.Drawing.Printing.Margins(60, 60, 60, 60);
ps.PageSettings.Assign(margins, _paperKind, _landScape);
 
         }
}
客户端如何使用：实例化PrintSettingController，进行参数设置，包括页眉页脚横纵向纸型，当然所有这些设置信息也可以在PrintSettingControll类里进行设置了，我这里是需求的需要，所以加在了外面，PrintSystem.PageSettings属性是XtraPageSettings类型，XtraPageSettings类封装了所有的页面设置信息，你可以在LoadPageSetting()函数里面进行修改，来实现自己想要的功能，例如可以把设置信息保存成XML文件
PrintSettingController psc =  new PrintSettingController( this .gridControl1);
//页眉
psc.PrintHeader =  this .Text;
 
//页脚
psc.PrintFooter =  this .dateTimePicker1.Text.ToString();
 
//横纵向
psc.LandScape =  this .rbtnHorizon.Checked;
 
//纸型
psc.PaperKind = System.Drawing.Printing.PaperKind.A4;
//加载页面设置信息
psc.LoadPageSetting();
 
psc.Preview();
