Developer Express 之 XtraReport如何顯示設計窗體

XtraReport的設計器，其實用XRDesignFormEx就可以。

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using DevExpress.XtraReports.UI;
using DevExpress.XtraReports.UserDesigner;
using System.Drawing.Design;
using System.ComponentModel.Design;

namespace WFAXtraReport
{
    public partial class Form1 : Form
    {
        XtraReport r ;//這個可以是加載之前設計好的模板
        public Form1()
        {
            InitializeComponent();
        }

        private void designForm_FormClosing(object sender, FormClosingEventArgs e)
        {
            //在此處處理關閉設計器時的操作，主要用來自定義保存數據
            //r.SaveLayout(@"C:\1.repx");
        }

        private void designForm_ReportStateChanged(object sender, ReportStateEventArgs e)
        {
            //只要報表發生改變就立即將狀態設置為保存
            //避免系統默認保存對話框的出現
            if (e.ReportState == ReportState.Changed)
            {
                ((XRDesignFormEx)sender).DesignPanel.ReportState = ReportState.Saved;
            }
        }

        private void Form1_Load(object sender, EventArgs e)
        {
            r = new XtraReport();
            //r.LoadLayout(@"C:\1.repx");
            XRDesignFormEx designForm = new XRDesignFormEx();

            //隱藏按鈕
            designForm.DesignPanel.SetCommandVisibility(new ReportCommand[]{
                ReportCommand.NewReport,
                ReportCommand.SaveFileAs,
                ReportCommand.NewReportWizard,
                ReportCommand.OpenFile
            }, CommandVisibility.None);


            //更改狀態
            designForm.ReportStateChanged += new ReportStateEventHandler(designForm_ReportStateChanged);

            designForm.FormClosing += new FormClosingEventHandler(designForm_FormClosing);

            // 加載報表. 
            designForm.OpenReport(r);

            // 打開設計器
            designForm.ShowDialog();

            designForm.Dispose();
        }
    }
}
這樣我們就能在加載和銷毀設計窗體的時候要控制什么，你可以重載里面的數據。比如設計窗體顯示有點慢，我們在開始的時候加載個等待窗體，顯示出來后關閉這個
