public partial class MainForm : Form

{

XRDesignFormEx designForm = null;

XtraReport report = null;

public MainForm()

{

InitializeComponent();

designForm = new XRDesignFormEx();

report = new XtraReport();

InitReport();

this.WindowState = FormWindowState.Maximized;

}

//加载报表

private void InitReport()

Report.DefaultReport Default = new DefaultReport();
Default.SaveLayout(defaultFile);
Default.Dispose();
}
report.LoadLayout(defaultFile);

report.DataSource = CreateDataTable(); //此处是一个datatable自己创建

BindTableData(CreateDataTable());
report.ReportUnit = DevExpress.XtraReports.UI.ReportUnit.TenthsOfAMillimeter; //设置单位为mm
report.PaperKind = System.Drawing.Printing.PaperKind.Custom; //纸张类型自定义
//隐藏按钮
designForm.DesignPanel.SetCommandVisibility(new ReportCommand[]{
ReportCommand.NewReport,
ReportCommand.SaveFileAs,
ReportCommand.OpenFile
}, CommandVisibility.None);
//自动保存
designForm.ReportStateChanged += designForm_ReportStateChanged;
// 加载报表.
designForm.OpenReport(report);
designForm.TopLevel = false;

designForm.Dock = DockStyle.Fill;
this.splitContainer1.Panel2.Controls.Add(designForm);
//保存模板到指定位置
designForm.FileName = Path.Combine(FileSaveFilePath, "DefaultReport.repx");
designForm.Show();

}

//自动保存

void designForm_ReportStateChanged(object sender, ReportStateEventArgs e)
{
//只要报表发生改变就立即将状态设置为保存
//避免系统默认保存对话框的出现
if (e.ReportState == ReportState.Changed)
{

//中有tablecell绑定数据

private void BindTableData(DataSet ds)

XRTableCell2.TextAlignment = DevExpress.XtraPrinting.TextAlignment.TopLeft;
for (int i = 1; i < ds.Tables["Table"].Rows.Count; i++)
{
if (i > 11)
{
XRTableCell2.Text += "" + ds.Tables["Table"].Rows[i][0] + "\r\n";
}
