Question

我有一个名为reportviewer1.a报告的报告查看器，名为report.rldc。我使用以下代码获取数据并进入数据表。现在我想在报表查看器中显示数据表的数据。代码如下所述。请帮忙:(

SqlDataAdapter dataadapter = new SqlDataAdapter(command);
DataTable table = new DataTable();
table.TableName = "Report showing result for                 " +   
ComboBoxCategory.SelectedItem.ToString()+" +  
ComboBoxQueryChoice.SelectedItem.ToString() +" from " + 
dateTimePickerStarting.Value.ToString()+" to "+dateTimePickerEnding.Value.ToString();
table.Clear();
dataadapter.Fill(table);

命令文本是

SELECT Distinct Sale.Product_ID , S_Article , 
    S_Size , SUM(S_Quantity) AS QuantitySold,SUM(Profit) AS Profit 
FROM Product,Sale 
WHERE Product.Product_ID=Sale.Product_ID 
and(S_Date between (@Startdate) 
and (@Enddate))" + SelectedCateogry + 
" Group By Sale.Product_ID,(S_Article),(S_Size) 
Order BY Profit DESC"

        dataadapter= new SqlDataAdapter(cmd);
        new SqlDataAdapter(cmd).Fill(someDataTable);
    }
}
