How to wait for element to be clickable in WebDriver with C#

Question

How can I wait for element to be clickable in Selenium WebDriver?

When I execute my tests in Firefox or Internet Explorer I have no problems, but when I try to run it on Chrome, I get an element is not clickable error when I try to click on the submit button. I tried with verifying that the element is there and it is visible and enabled.

Please give your answers in C#.

Answer 1

Below code should help you.

public static class WebDriverExtensions
{
    public static IWebElement FindElement(this IWebDriver driver, By by, int timeoutInSeconds)
    {
        if (timeoutInSeconds > 0)
        {
            var wait = new WebDriverWait(driver, TimeSpan.FromSeconds(timeoutInSeconds));
            return wait.Until(drv => drv.FindElement(by));
        }
        return driver.FindElement(by);
    }
}

I have been using this line of code when I first create my browser instance

[Given(@"I have opened an IE browser")]
public void GivenIHaveOpenedAnIEBrowser()
{

    Ie = new InternetExplorerDriver();
    Ie.Manage().Timeouts().ImplicitlyWait(TimeSpan.FromMilliseconds(FiveSeconds));
}

it's actually the second line in this method, I have a couple of different times factored into constants because I had the same issue in IE. most of my issues were caused by overlapping tests, but there were quite a few times where the DOM wasn't loaded completely yet.

This really helped, I cannot remember where I found this solution, it was somewhere on SO.

This may caused by any web elements which is overlapping with submit button. For an example, you have clicked on a dropdown and item lists are long so it may over lap the submit button. FireFox and IE can click on the submit button in this scenario but chrome can not. You can scroll to the submit button and click on it. you can use

wait.Until(ExpectedConditions.ElementToBeClickable(By locator));

In many cases selenium does not get the element even though it is present. script works some times and fails as well. This code works when actual element is present but selenium is not find it. I have create a loop for given count ant it returns true.

 public static bool waitTillElementisDisplayed(IWebDriver driver, By by, int timeoutInSeconds)
    {
        bool elementDisplayed = false;

        for (int i = 0; i < timeoutInSeconds; i++)
        {
            try
            {
                if (timeoutInSeconds > 0)
                {
                    var wait = new WebDriverWait(driver, TimeSpan.FromSeconds(timeoutInSeconds));
                    wait.Until(drv => drv.FindElement(by));
                }
                elementDisplayed = driver.FindElement(by).Displayed;
            }
            catch
            { }
        }
        return elementDisplayed;

    }

//define method
public void WaitFindAndClick(IWebDriver parent, By by, int counter)
{
   bool Displayed = false;

   for (int v = 0; v < counter; counter++)
   {
       try
       {
           Thread.Sleep(2000);
           WebDriverWait wait = new WebDriverWait(driver, TimeSpan.FromSeconds(10));
           wait.Until((d) => { return parent.FindElement(by); });

           Displayed = parent.FindElement(by).Displayed;

           if (Displayed)
           {
               parent.FindElement(by).Click();
               break;
           }
       }
       catch
       {
       }
   }
}

// Call method
testutil.WaitFindAndClick(driver, By.Id("btnApplyForFunding"), 10);
