How to maximize the browser window in Selenium WebDriver (Selenium 2) using C#?

Question

Is there any way to maximize the browser window using WebDriver (Selenium 2) with C#?

Answer 1

We have observed bug with new driver libraries. You can use slightly old jars which are able to handle new browsers versions.

The main generic option is :-

driver.manage().window().maximize();

You can also use other option for maximizing the browser window.

Example:-

Add below option and pass it to driver:-

    chromeOptions.addArguments("--start-maximized");

The full code will look like below :-

System.setProperty("webdriver.chrome.driver","D:\\Workspace\\JmeterWebdriverProject\\src\\lib\\chromedriver.exe");
ChromeOptions chromeOptions = new ChromeOptions();
chromeOptions.addArguments("--start-maximized");
driver = new ChromeDriver(chromeOptions);

OR

Toolkit toolkit = Toolkit.getDefaultToolkit();
int Width = (int) toolkit.getScreenSize().getWidth();
int Height = (int)toolkit.getScreenSize().getHeight();
//For Dimension class, Import following library "org.openqa.selenium.Dimension"  
driver.manage().window().setSize(new Dimension(Width,Height));
driver.get("https://google.com");

Try this on safari :-

JavascriptExecutor jse = (JavascriptExecutor)driver;
String screenWidth = jse.executeScript("return screen.availWidth").toString();
String screenHeight = jse.executeScript("return screen.availHeight").toString();
int intScreenWidth = Integer.parseInt(screenWidth);
int intScreenHeight = Integer.parseInt(screenHeight);
Dimension d = new Dimension(intScreenWidth, intScreenHeight);
driver.manage.window.setSize(d);
