Unable to locate element using Selenium Chromedriver when it's there in C#

Question

I am trying to get my program to click on a button however I receive errors.

My code:

driver.FindElementById("couponsinc-gallery-selectall").Click();

Error:

An unhandled exception of type 'OpenQA.Selenium.NoSuchElementException' occurred in WebDriver.dll
no such element: Unable to locate element: {"method":"css selector","selector":"#\couponsinc\-gallery\-selectall"}

Here is the code of the button on the page:

<div class="selectall">
            <input type="checkbox" class="selectall-chk" id="couponsinc-gallery-selectall">
            <label for="couponsinc-gallery-selectall">Clip All</label>
        </div>

I've also tried my using FindElementByClassName but nothing is working. What am I doing wrong?

The checkbox with text as Clip All an <iframe> so you have to:

Induce WebDriverWait for the desired frame to be available and switch to it.
Induce WebDriverWait for the desired element to be clickable.
You can use either of the following Locator Strategies:

Using CSS_SELECTOR:

((IJavaScriptExecutor)driver).ExecuteScript("return scrollBy(0, 800);");
new WebDriverWait(driver, TimeSpan.FromSeconds(20)).Until(ExpectedConditions.FrameToBeAvailableAndSwitchToIt(By.CssSelector("iframe[title='Coupons']"));
new WebDriverWait(driver, TimeSpan.FromSeconds(20)).Until(ExpectedConditions.ElementToBeClickable(By.CssSelector("input.selectall-chk#couponsinc-gallery-selectall"))).Click();

Using XPATH:

((IJavaScriptExecutor)driver).ExecuteScript("return scrollBy(0, 800);");
new WebDriverWait(driver, TimeSpan.FromSeconds(20)).Until(ExpectedConditions.FrameToBeAvailableAndSwitchToIt(By.XPath("//iframe[@title='Coupons']"));
new WebDriverWait(driver, TimeSpan.FromSeconds(20)).Until(ExpectedConditions.ElementToBeClickable(By.XPath("//input[@class='selectall-chk' and @id='couponsinc-gallery-selectall']"))).Click();

I've tried this and have gotten this error: OpenQA.Selenium.WebDriverTimeoutException: 'Timed out after 20 seconds' with the same inner exception: NoSuchElementException: no such element: Unable to locate element, here is the website: https://www.keyfood.com/store/keyFood/en/printable-coupons, you can test it for yourself, it's the "Clip All" button near the bottom of the page. – creed Jul 17 '20 at 20:34

This time I got this exception: OpenQA.Selenium.WebDriverTimeoutException: 'Timed out after 20 seconds' followed by this inner exception: InvalidSelectorException: invalid selector: An invalid or illegal selector was specified which occured on this line: new WebDriverWait(driver, TimeSpan.FromSeconds(20)).Until(ExpectedConditions.ElementToBeClickable(By.CssSelector("//input.selectall-chk#couponsinc-gallery-selectall"))).Click(); – creed Jul 17 '20 at 21:17
@africohal My bad, it was a typo, fixed it, please check now both the locators and let me know the status. – undetected Selenium Jul 17 '20 at 21:20

Awesome! The solution seems to work and I've marked it as the soltuion but I still don't understand why my simple code doesn't work as it definitely worked for a different button on a different website. – creed Jul 17 '20 at 21:23
@africohal I tried my best to provide you all the reference in the form on embedded links. Happy coding – undetected Selenium Jul 17 '20 at 21:25
