如何使用Devexpress获取已经在C#.Net中创建的模板/报告

本文关键字：创建 报告 Net Devexpress 何使用 获取 | 更新日期: 2023-09-27 18:20:56

我在C#.Net中使用DevExpress工具进行项目。我创建了一些模板/报告（XtraReport），并通过此链接创建了单独显示这些模板的按钮。

现在我需要获得所有模板的名称，并希望在DropDown中显示，最终用户选择并单独查看每个模板？？

我可以从设计器中获得我创建的模板，并从bin>Debug>UserTemplates.repx格式文件外部存储这些模板，并使用此代码存储在下拉列表中并显示在预览中。

printBarManager1.PrintControl = printControl1;
XtraReport RptObj = XtraReport.FromFile(Application.StartupPath + @"'UserTemplates'" + CBL_QuoteTempList.EditValue + ".repx", true);
RptObj.CreateDocument();
printControl1.PrintingSystem = RptObj.PrintingSystem;

但是我需要得到我创建的模板吗？如何获取？去哪里？建议我或帮助我解决这个问题。

提前谢谢。Srihari

如何使用Devexpress获取已经在C#.Net中创建的模板/报告

据我所知，您有一个包含*.repx文件的文件夹，但您不知道如何让用户选择其中一个。

您可以使用此代码加载组合

public static void loadCombo(ComboBoxEdit control) 
{
        string path = @"C:'FolderWithRepxFiles'";
        string[] filePaths = Directory.GetFiles(path, "*.repx");
        control.Properties.Items.Clear();
        foreach (string item in filePaths)
            control.Properties.Items.Add(System.IO.Path.GetFileNameWithoutExtension(item));
}

然后您可以使用此打印/打印预览报告

public static void PrintPreview(ComboBoxEdit control)
{
      string selection = control.SelectedItem as string;
      string fullPath = @"C:'FolderWithRepxFiles'" + selection + ".repx";
      XtraReport rr = XtraReport.FromFile(fullPath, true);
      ReportPrintTool printTool = new ReportPrintTool(rr);
      printTool.ShowRibbonPreview();
      //printTool.Print();
}

若要自定义保存过程，必须创建一个自定义命令处理程序。以下是您的操作方法：

XRDesignRibbonForm designForm = new XRDesignRibbonForm();
designForm.OpenReport(Your_Report_Object);
XRDesignPanel panel = designForm.ActiveDesignPanel;
designForm.ActiveDesignPanel.SetCommandVisibility(ReportCommand.SaveFileAs, DevExpress.XtraReports.UserDesigner.CommandVisibility.None);
designForm.ActiveDesignPanel.SetCommandVisibility(ReportCommand.SaveAll, CommandVisibility.None);
designForm.ActiveDesignPanel.SetCommandVisibility(ReportCommand.ShowPreviewTab, CommandVisibility.None);
designForm.ActiveDesignPanel.SetCommandVisibility(ReportCommand.ShowHTMLViewTab, CommandVisibility.None);
designForm.ActiveDesignPanel.SetCommandVisibility(ReportCommand.ShowTabbedInterface, CommandVisibility.None);
if (panel != null)
      panel.AddCommandHandler(new SaveCommandHandler(panel));
designForm.ShowDialog();

您将需要此类

 public class SaveCommandHandler : DevExpress.XtraReports.UserDesigner.ICommandHandler
 {
        XRDesignPanel panel;
        string NewPathX = null;
        public SaveCommandHandler(XRDesignPanel panel)
        {
            this.panel = panel;
        }
        void Save()
        {
            //Show a form with a textbox and ask the user to give you a name for the report
            string fileName = "UserSelectedFileName";
            fileName = @"C:'YourDefaultFolder" + fileName + ".repx";
            panel.Report.SaveLayout(fileName);

            panel.ReportState = ReportState.Saved;
        }
        public bool CanHandleCommand(ReportCommand command, ref bool useNextHandler)
        {
            useNextHandler = command != ReportCommand.SaveFile;
            return command == ReportCommand.SaveFile;
        }
        public void HandleCommand(ReportCommand command, object[] args)
        {
            bool handled = false;
            if (!CanHandleCommand(command, ref handled)) return;
            Save();
        }
    }
