datagird中显示报表中不显

[chpst]

private void BindIOProductData(int nStoreInOutID)
{
///定义获取数据的类
MisStock.Components.IOProduct product = new MisStock.Components.IOProduct();
SqlDataReader recp = product.GetProductByStoreInOut(nStoreInOutID);

///创建DataSet数据源
DataTable dataTable = SystemTools.ConvertDataReaderToDataTable(recp);
DataSet dataSet = new DataSet("IOProduct");
dataSet.Tables.Add(dataTable);

///设定控件的数据源
IOProductList.DataSource = dataSet;
///绑定控件的数据
IOProductList.DataBind();
}

绑定到DataGrid上显示没问题。

===============================

private void BindProductData(int nStoreInOutID)
{
MisStock.Components.IOProduct product = new MisStock.Components.IOProduct();
SqlDataReader recp = product.GetProductByStoreInOut(nStoreInOutID);

//创建DataSet数据源
DataTable dataTable = SystemTools.ConvertDataReaderToDataTable(recp);
CrystalReport2 oCR= new CrystalReport2();
DataSet1 ds = new DataSet1();
ds.Tables.Add(dataTable);
oCR.SetDataSource(ds);
oCR.SetDatabaseLogon("sa","","HWB","ASPNETMisDB");

this.CrystalReportViewer1.ReportSource=oCR;
this.CrystalReportViewer1.Zoom(1);
}
=====================================

就不显示是空的用的是模式数据集，那位高手指点一二，谢谢！

单从语法上看不出来什么错误，
用oCR.SetDataSource(ds.Tables[0]);试试--指定到table

你的CrystalReport2是不是有問題？你看看CS源碼。
public class CrystalReport2 : ReportClass {

public CrystalReport2() {
}

public override string ResourceName {
get {
return "CrystalReport2.rpt";//是否讀入正確的報表
}
set {
// Do nothing
}
}

[chpst]

private void BindProductData(int nStoreInOutID)
{
int i;
string strProvider="Server=(local);Database=ASPNETMisDB;UID=sa;PWD=";
CrystalReport2 oCR = new CrystalReport2();
DataSet1 ds = new DataSet1();
SqlConnection MyConn=new SqlConnection(strProvider);
MyConn.Open();
StoreInOutID = " + nStoreInOutID ;
string strSel = "SELECT IOProduct.*,[Product].ProName FROM IOProduct INNER JOIN [Product] ON [Product].ProductID = IOProduct.ProductID WHERE StoreInOutID = " + nStoreInOutID ;
SqlDataAdapter MyAdapter = new SqlDataAdapter(strSel,MyConn);
MyAdapter.Fill(ds,"IOProduct");
MyAdapter.Fill(ds,"Product");
oCR.SetDataSource(ds);
this.CrystalReportViewer1.ReportSource=oCR;
this.CrystalReportViewer1.Zoom(1);
}
这样就可以。
