Developer Express 之 XtraReport如何显示设计窗体，打开已设计过的报表

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
