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);

Answer 2

For IE and Firefox:

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

For Chrome:

ChromeOptions options = new ChromeOptions();
options.addArguments("--start-maximized");
driver = new ChromeDriver( options )

Answer 3

This option is fine for me :

ChromeOptions options = new ChromeOptions();
options.addArguments("start-fullscreen");

This option works on all OS.

Answer 4

using System.Windows.Forms;
using System.Drawing;

public static void MaximizeBrowser(this IE myBrowser)
{
    myBrowser.SizeWindow(Screen.PrimaryScreen.WorkingArea.Width, Screen.PrimaryScreen.WorkingArea.Height);
}

I used Jim's code, but slightly modified for use with WatiN and C# to maximize the browser.

Answer 5

Here's what worked for me in C#, firefoxDriver is global to the class:

in the usings:

using System.Drawing;
using System.Windows.Forms;

---

in the code:

this.firefoxDriver = new FirefoxDriver();
this.firefoxDriver.Manage().Window.Position = new Point(0, 0);
this.firefoxDriver.Manage().Window.Size = new Size(Screen.PrimaryScreen.WorkingArea.Width, Screen.PrimaryScreen.WorkingArea.Height);

Answer 6

You can use something like this (C#):

driver.Manage().Window.Size = new Size(1024, 768);
