Hi shubhangi, You can do it in two ways in query as below str = "select customer.custid,customer.custname,customer.custaddress,product.prodname,product.prodprice from customer, product where customer.prodid = product.prodid"; str = "select cust.custid,cust.custname,cust.custaddress,prod.prodname,prod.prodprice FROM customer cust INNER JOIN product prod ON cust.prodid = prod.prodid"; Untitled Page using System; using System.Configuration; using System.Data; using System.Linq; using System.Web; using System.Web.Security; using System.Web.UI; using System.Web.UI.HtmlControls; using System.Web.UI.WebControls; using System.Web.UI.WebControls.WebParts; using System.Xml.Linq; using System.Data.SqlClient; public partial class _Default : System.Web.UI.Page { string connStr = ConfigurationManager.ConnectionStrings["ConnectionString"].ConnectionString; SqlCommand com; SqlDataAdapter sqlda; DataSet ds; string str; protected void Page_Load(object sender, EventArgs e) { if (!IsPostBack) { bindgrid(); } } void bindgrid() { SqlConnection con = new SqlConnection(connStr); con.Open(); str = "select customer.custid,customer.custname,customer.custaddress,product.prodname,product.prodprice from customer, product where customer.prodid = product.prodid"; //str = "select cust.custid,cust.custname,cust.custaddress,prod.prodname,prod.prodprice FROM customer cust INNER JOIN product prod ON cust.prodid = prod.prodid"; com = new SqlCommand(str, con); sqlda = new SqlDataAdapter(com); ds = new DataSet(); sqlda.Fill(ds, "customer"); GridView1.DataSource = ds; GridView1.DataMember = "customer"; GridView1.DataBind(); con.Close(); } } Thanks
