首先看下布局designer

细节：

　　分组一定要用到GroupHeather

 

设置好有 右边会出现

 

 接下来是代码部分

 

　　Form1中代码

　　

using DevExpress.XtraReports.UI;

  private DataSet getds()
        {

            DataSet ds = new DataSet();
            string constr = "server=192.168.100.222;user=sa;pwd=p@ssw1rd;database=pwd1";
            SqlConnection mycon = new SqlConnection(constr);

            try
            {
                mycon.Open();
                SqlCommand mycom = new SqlCommand("select * from mulittb", mycon);
                SqlDataAdapter dpt = new SqlDataAdapter(mycom);
                dpt.Fill(ds, "mulittb");
                mycon.Close();


            }
            catch (Exception ex)
            {

                MessageBox.Show(ex.Message);
            }

            return ds;
        }
        //显示
        private void simpleButton1_Click(object sender, EventArgs e)
        {
            DataSet ds = getds();
            XtraReport1 report = new XtraReport1(ds);
            report.Landscape = true;
            documentViewer1.DocumentSource = report;
            report.CreateDocument();
        }
        //预览
        private void simpleButton2_Click(object sender, EventArgs e)
        {
            DataSet ds = getds();
            XtraReport1 report = new XtraReport1(ds);
            report.Landscape = true;
            report.ShowPreviewDialog();
        }

Xtrareport代码

　　

   public XtraReport1(DataSet ds)
        {
            InitializeComponent();
            this.DataSource = ds;
            this.DataMember = "mulittb";
            xrTableCell1.DataBindings.Add("Text",ds,"type");
            //设置groupHeader分组字段 (type  ,报表列 排序类型.上升asc) 可以不写
            GroupField fz = new GroupField("type",XRColumnSortOrder.Ascending);
            //把分组字段添加进GroupHeader1 
            ((GroupHeaderBand)(this.FindControl("GroupHeader1", true))).GroupFields.Add(fz);
            //绑定显示多列的字段
            this.xrTableCell2.DataBindings.Add("Text",ds,"name");

        }
