How to achieve the join query in c# code behind file and display the result in gridview..

Quote:
Assume that there are two tables: Products and Sales

Products:

ProductID | Name | Manfacturer | Rate | Date
-------------------------------------------------------
1 Scooty TVS 35000 10/10/2012
2 Splendor Hero Honda 50000 5/6/2012

Sales:

SaleID | CustomerID | ProductID | Qty | SoldDate
------------------------------------------------------
1 1 2 1 12/12/2012

Here i want to join these two tables. It will return the matching records in both tables.

SELECT S.SaleID, P.ProductID, P.ProductName, P.Manfacturer, S.CustomerID, S.SoldDate, S.Qty,P.Rate, (s.Qty * P.Rate) AS [Total] FROM Products P INNER JOIN Sales S ON s.ProductID = P.ProductID

The above query returns the result set as

SaleID | ProductID | ProductName | Manfacturer | CustomerID | SoldDate | Qty | Rate | Total
---------------------------------------------------------------------------------------------------------
1 2 Splendor Hero Honda 1 12/12/2010 1 50000 50000.00

using (SqlConnection con = new SqlConnection("connectionString"))

    DataSet ds = new DataSet();
    sadp.Fill(ds);
