Scroll Bar not working - Selenium Webdriver

Question

Attached is the picture of the scroll bar that I would like to move.

I already have a method that is not working. could you please tell me what's wrong?

    public static void ScrollPageToEnd(this IWebDriver Driver)
    {
        var maxScrollY = Driver.Scripts().ExecuteScript("return document.documentElement.scrollHeight;");
        Driver.Scripts().ExecuteScript("window.scrollTo(0," + maxScrollY + ")");        

    }

Where do you want to move scroll? end of page? or, move to a specific element's location? — Mahsum Akbas, Aug 16 '18 at 06:58
@RyanWilson - Yes maxScrollY shows the height. Is there any way I can find out if the scroll height is correct or not? — user2320213, Aug 16 '18 at 12:17

It is possible that var maxScrollY is not a string, (ExecuteScript returns object from what I can recall). Try to save the object ExecuteScriptto a string with string maxScrollY = Driver.Scripts().ExecuteScript("return document.documentElement.scrollHeight;").ToString().

Also, check with debug the object's value and see what window.scrollTo(0," + maxScrollY + ") equals to.

You're right that `IJavaScriptExecutor.ExecuteScript` returns an object, but concatenating a string and an object calls ToSring on that object, so I don't believe that that's the problem – Arnon Axelrod Aug 16 '18 at 06:17

Use scrollIntoView function of JavascriptExecutor interface to scroll to that location where the Image is.

WebElement element = driver.findElement("locator of the image")
JavascriptExector js = (JavascriptExecutor)driver;
js.executeScript("argument[0].scrollIntoView");",element)

or

we can use method Scroll(x,y) to scroll to particular location

it is working for me:

((IJavaScriptExecutor)Driver).ExecuteScript("window.scrollTo(0, document.body.scrollHeight)");

i use it as a function to be easier:

public void ScrollToEndOfThePage()
        {
            ((IJavaScriptExecutor)Driver).ExecuteScript("window.scrollTo(0, document.body.scrollHeight)");
        }

if any JS script is not helping you to scroll, then try MoveToElement?

IWebElement element = driver.FindElement(By.Id("yourLookingId"));
new Actions(driver).MoveToElement(element).Perform();

I am using this in a complicated web application with scroll bar and it works perfectly.
