Implicit wait Command Not Working-selenium webdriver C#

Question

Guys, I have started to work on selenium web driver. You can assume I am a beginner. At the moment I am having difficulties in implementing the implicit wait command in my code (C#). it is not working as it should and result in an exception due to Element not found, however when I add the "Thread.Sleep(3000) the code get executed flawlessly. I have been looking for the solution all over the internet but not able to resolve the problem. Below I have mentioned sample code.

class Entrypoint
{

static void Main()

{
 IWebDriver driver = new ChromeDriver();
    **driver.Manage().Timeouts().ImplicitWait = TimeSpan.FromSeconds(20);**
    driver.Navigate().GoToUrl("https://r1.netrevelation.com:8443/mcba-cms/pages/flight-transfer.cab");
    driver.Manage().Window.Maximize();


    driver.FindElement(By.Id("loginlink")).Click();
    driver.FindElement(By.Id("headerSubView:inputUserName:input")).SendKeys("st001");
    driver.FindElement(By.Id("headerSubView:inputPassword:input")).SendKeys("hello321" + Keys.Enter);

    driver.FindElement(By.Id("dateOfFlight:input")).Click();**//This Step does not get Executed , it throws exception element not found.**
    driver.FindElement(By.Id("ui-datepicker-div")).Click(); 
    driver.FindElement(By.XPath(".//*[@id='ui-datepicker-div']/div/a[2]/span")).Click(); 
    driver.FindElement(By.LinkText("28")).Click(); 
    IWebElement Flightno = driver.FindElement(By.Id("selectedFlight:input"));
    Flightno.SendKeys("BA901" + Keys.Enter);
    IWebElement Flighttick = driver.FindElement(By.Id("flightTickImg"));


    driver.Quit();

Please note that at the moment I don't want to use explicit wait, as implicit will serve my need (if it starts working). The above code Run in supersonic speed for somehow it manages to Login into the system but afterward it Fails every time reason being once Login request is made system pauses for 2-3 seconds. Please provide your comment in this regard.

As per the documentation, an Implicit Wait is to tell the WebDriver to poll the HTML DOM for a certain amount of time when trying to find an element() or find all elements() if they are not immediately available. But availability of an element in the DOM Tree doesn't guarantees that the ElementToBeClickable as you have tried in your code block. Hence you face the exception as Element not found.

Solution:

So the solution to your issue is to induce Explicit Wait i.e. WebDriverWait with ExpectedConditions clause as ElementToBeClickable which will not only confirm the availability of an element in the HTML DOM but also ensure that the Element is Clickable i.e. Element is Displayed and Enabled as follows:

WebDriverWait wait = new WebDriverWait(driver, TimeSpan.FromSeconds(10));
IWebElement element = wait.Until(ExpectedConditions.ElementToBeClickable(By.Id("loginlink")));
