好呀，請幫忙。修改文本
protected System.Web.UI.WebControls.Button btnChangeText;
protected CrystalDecisions.Web.CrystalReportViewer cRV;
myReport ReportDoc = new myReport();
private void Page_Load(object sender, System.EventArgs e)
{
// 在此处放置用户代码以初始化页面
string strProvider = "Server=(local);DataBase=Northwind;UID=sa;PWD=111";
SqlConnection MyConn = new SqlConnection(strProvider);
MyConn.Open();
string strSelOrders = "Select * from orders";
string strSelOrdersDetails = "Select * from [Order Details]";
SqlDataAdapter daOrder = new SqlDataAdapter(strSelOrders,MyConn);
SqlDataAdapter daOrderDetails = new SqlDataAdapter(strSelOrdersDetails,MyConn);
DataSet ds = new DataSet();
daOrder.Fill(ds,"orders");
daOrderDetails.Fill(ds,"Order Details");
ReportDoc.SetDataSource(ds);
cRV.ReportSource = ReportDoc;
}
private void btnChangeText_Click(object sender, System.EventArgs e)
{
TextObject tb = (TextObject )ReportDoc.ReportDefinition.ReportObjects["Text2"];
tb.Text = "订单号";
}
