vs2010 下使用水晶报表 后台绑定代码如下
- C# code
private ReportDocument myArea; protected void Page_Load(object sender, EventArgs e) { if (!Page.IsPostBack) { Initialize(); } } private void Initialize() { CRBind(); } private void CRBind() { DataSet ds = new DataSet(); string strSql = "select p.name as Province,c.name as City, a.name as Area,a.code as ZIP from province p left join city c on p.code=c.fid left join area a on c.code=a.fid"; using (SqlConnection Conn = new SqlConnection(ConfigurationManager.ConnectionStrings["AreaDB"].ConnectionString)) { SqlDataAdapter sda = new SqlDataAdapter(strSql, Conn); sda.Fill(ds,"Area"); } string filePath = Server.MapPath("CrystalReportPush.rpt"); myArea = new ReportDocument(); myArea.Load(filePath); myArea.SetDataSource(ds.Tables["Area"]); CrystalReportViewer1.ReportSource = myArea; CrystalReportViewer1.DataBind(); } }页面就一个CrystalReportViewer 控件 ，有一个 ds.xsd的数据集文件 。
ds.table["Area"]是一个全国行政区划的表 ，字段在下边语句中。
select p.name as Province,c.name as City, a.name as Area,a.code as ZIP from province p left join city c on p.code=c.fid left join area a on c.code=a.fid
运行后显示第一页，北京的数据，其他数据不显示，翻页就提示 “没有有效的报表源”。看了很多问题提示什么的，都没有解决。初次接触水晶报表，彻底无解了。
附webconfig文件引用
- XML code
