Developer Express 之 XtraReport如何显示设计窗体

XtraReport的设计器，其实用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 ;//这个可以是加载之前设计好的模板
        public Form1()
        {
            InitializeComponent();
        }

        private void designForm_FormClosing(object sender, FormClosingEventArgs e)
        {
            //在此处处理关闭设计器时的操作，主要用来自定义保存数据
            //r.SaveLayout(@"C:\1.repx");
        }

        private 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)
            {
                ((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();

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


            //更改状态
            designForm.ReportStateChanged += new ReportStateEventHandler(designForm_ReportStateChanged);

            designForm.FormClosing += new FormClosingEventHandler(designForm_FormClosing);

            // 加载报表. 
            designForm.OpenReport(r);

            // 打开设计器
            designForm.ShowDialog();

            designForm.Dispose();
        }
    }
}
这样我们就能在加载和销毁设计窗体的时候要控制什么，你可以重载里面的数据。比如设计窗体显示有点慢，我们在开始的时候加载个等待窗体，显示出来后关闭这个
