FastReport.NET v2021 打印动态图片报表 | 软件开发平台

作为CSFrameworkV6旗舰版软件开发平台重要demo, 使用FastReport.NET v2021 打印动态图片报表。

C# 源码

C# Code:

/// <summary>
/// 生成报表实例
/// </summary>
/// <returns></returns>
private FastReport.Report InitializeReport()
{
//报表文件
string file = Application.StartupPath + @"\Reports\rptUser.frx";
FastReport.Report rptUser = new FastReport.Report();
rptUser.Load(file);//加载报表模板文件

//取报表数据
List<tb_MyUser> data = new bllUser().GetUserReportData(txtAccount.Text,
txtFrom.DateTime, txtTo.DateTime);
rptUser.RegisterData(data, "tb_MyUser"); //注册数据源,单表

//给DataBand(明细数据)绑定数据源
DataBand band = rptUser.FindObject("Data1") as DataBand;
DataSourceBase dataSource = rptUser.GetDataSource("tb_MyUser");
dataSource.Enabled = true; //重要！！！
band.DataSource = dataSource;

//自定义处理
band.BeforePrint += new EventHandler(band_BeforePrint);

(rptUser.FindObject("TextCustom") as TextObject).Text = Loginer.CurrentUser.AccountName;
rptUser.Parameters.FindByName("pPrintUser").Value = Loginer.CurrentUser.AccountName;
rptUser.Parameters.FindByName("pPrintTime").Value = DateTime.Now;

return rptUser;
}

C# Code:

/// <summary>
/// DataBand 打印时间处理图片
/// </summary>
/// <param name="sender"></param>
/// <param name="e"></param>
void band_BeforePrint(object sender, EventArgs e)
{
//取出当前打印的记录。
var row = (sender as DataBand).DataSource.CurrentRow as tb_MyUser;

//做其它特殊处理：
FastReport.Report rpt = (sender as DataBand).Report;
int i = (sender as DataBand).DataSource.CurrentRowNo;
(rpt.FindObject("TextCustom") as TextObject).Text = "Object行号:" + i.ToString();

//从后台获取图片
var data = new bll_Images().GetByDocType(Models.OtherModels.ImageDocType.User, row.Account, true, false);
if (data != null)
{
Image img = ImageHelper.FromBytes(data.ImgSmall);//将字节转换为图片
PictureObject pic = rpt.FindObject("Picture1") as PictureObject;
pic.Image =new Bitmap(img); //注意：必须是Bitmap, Image不受支持！
}
}
