c# - 如何使用 Devexpress 获取已在 C#.Net 中创建的模板/报告？

Question

我正在使用 DevExpress 工具在 C#.Net 中做项目。我创建了一些模板/报告 (XtraReport) 并创建了按钮来单独显示来自此 link 的模板.

现在我需要获取所有模板名称并希望在 DropDown 中显示，最终用户可以单独选择和查看每个模板 ??

我可以使用此代码获取从设计器创建并从 bin>Debug>UserTemplates .repx 格式文件外部存储的模板，并存储在下拉列表中并在预览中显示。

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

RptObj.CreateDocument();
printControl1.PrintingSystem = RptObj.PrintingSystem;

但我需要获取我创建的模板吗？如何获得 ？从哪里得到？建议我或帮助我解决这个问题。

提前致谢。斯里哈里

据我了解，您有一个包含 *.repx 文件的文件夹，但您不知道如何让您的用户选择其中一个文件。

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));
}

然后你可以用这个打印/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();
}

要自定义保存过程，您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();

你需要这门课

 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();
        }
    }
