dev中 ，usercontrol打印界面内容，打印预览和打印

首先，在对应的文件夹下面添加引用，如下图

如果没有就下载下来包。

预先在本地文件夹下面建立.frx文件，像这样的，

然后在触发事件下面写

//打印预览

private void btn_Preview_Click(object sender, EventArgs e)
{
string path = GetReportPath();    //该方法是获取绝对路径下面的.frx文件
if (string.IsNullOrWhiteSpace(path)) { return; }
FastReport.Report _report = new FastReport.Report();
_report.Load(path);
_report.PrintSettings.ShowDialog = true;
EnvironmentSettings FPEnvironmentSettings = new EnvironmentSettings();
FPEnvironmentSettings.ReportSettings.ShowProgress = true;
_report.RegisterData(GetPrintData());  //GetPrintData()方法是创建打印样式，和填充要打印的数据，绑定数据源，，，，，方法在下面

if (IsDesgin)
{
_report.Design();
}
else
{
_report.Show();
}
}

//打印

private void btn_Print_Click(object sender, EventArgs e)
{
string path = GetReportPath();
if (string.IsNullOrWhiteSpace(path)) { return; }
FastReport.Report _report = new FastReport.Report();
_report.Load(path);
_report.PrintSettings.ShowDialog = true;
EnvironmentSettings FPEnvironmentSettings = new EnvironmentSettings();
FPEnvironmentSettings.ReportSettings.ShowProgress = true;
_report.RegisterData(GetPrintData());
_report.Print();
}

//全局静态变量

public static String g_FolderPath = System.AppDomain.CurrentDomain.BaseDirectory + ReportConst.REPORT_SAVE_DIR + "\";

private bool IsDesgin = false;

//重写此方法

protected override bool ProcessCmdKey(ref Message msg, Keys keyData)
{
if (keyData == (Keys.Control | Keys.O | Keys.K))
{
if (IsDesgin) { IsDesgin = false; }
else
{
IsDesgin = true;
}
}
return base.ProcessCmdKey(ref msg, keyData);
}

//获取.frx文件路径

public string GetReportPath()
{
return g_FolderPath + "HD_" + "电子交接班" + ".frx";
}

//绑定要打印的数据源

{
DataSet dataSetPrint = new DataSet();   //先创建一个DataSet数据集
DataTable _EleCtronicHandover = new DataTable("电子交接班信息");    //创建要打印的表
