The html code highlighted is the code for the DropDownList.

I write a code for SelectedIndexChanged Event like this : OnselectIndexChanged="ddlProductSelectIndexChanged"  and wrote a event to handle this, but in vain, not firing the event:-

protected void ddlProduct_SelectIndexChanged(object sender, GridViewRowEventArgs e)
        {
            try
            {
                string strCon = ConfigurationManager.ConnectionStrings["ORDERS"].ToString();
                SqlConnection sqlCon = new SqlConnection(strCon);
                sqlCon.Open();
                DropDownList ddlProduct = (DropDownList)GridView1.Rows[0].FindControl("ddlProduct");
                SqlCommand cmd = new SqlCommand("getProductRateforCombo", sqlCon);
                cmd.Parameters.Add("@as_itemValue", SqlDbType.Decimal).Value = ddlProduct.SelectedValue;
                cmd.CommandType = CommandType.StoredProcedure;
                SqlDataAdapter adapter = new SqlDataAdapter(cmd);
                DataSet ds=new DataSet();
                adapter.Fill(ds);
                if (ds.Tables[0].Rows.Count > 0)
                {
                    TextBox txtRate = (TextBox)GridView1.Rows[0].FindControl("txtRate");
                    txtRate.Text = ds.Tables[0].Rows[0]["Mrp"].ToString();
                }
            }
            catch (Exception ex)
            {
               
                throw;
            }
        }
