Selenium C# WebDriver: Wait until element is present

Question

I want to make sure that an element is present before the webdriver starts doing stuff.

I\'m trying to get something like this to work:

WebDriverWait w         


        

Answer 1

Python:

from selenium import webdriver
from selenium.webdriver.support import expected_conditions as EC
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.common.by import By

driver.find_element_by_id('someId').click()

WebDriverWait(driver, timeout).until(EC.presence_of_element_located((By.ID, 'someAnotherId'))

from EC you can choose other conditions as well try this: http://selenium-python.readthedocs.org/api.html#module-selenium.webdriver.support.expected_conditions

Answer 2

You can use the following

WebDriverWait wait = new WebDriverWait(driver, new TimeSpan(0,0,5));
wait.Until(ExpectedConditions.ElementToBeClickable((By.Id("login")));

Answer 3

Try this code:

 New WebDriverWait(driver, TimeSpan.FromSeconds(10)).Until(Function(d) d.FindElement(By.Id("controlName")).Displayed)

Answer 4

I see multiple solutions already posted that work great! However, just in case anyone needs something else, I thought I would post two solutions that I personally used in selenium C# to test if an element is present! Hope it helps, cheers!

public static class IsPresent
{
    public static bool isPresent(this IWebDriver driver, By bylocator)
    {

        bool variable = false;
        try
        {
            IWebElement element = driver.FindElement(bylocator);
            variable = element != null;
        }
       catch (NoSuchElementException){

       }
        return variable; 
    }

}

Here is the second

    public static class IsPresent2
{
    public static bool isPresent2(this IWebDriver driver, By bylocator)
    {
        bool variable = true; 
        try
        {
            IWebElement element = driver.FindElement(bylocator);

        }
        catch (NoSuchElementException)
        {
            variable = false; 
        }
        return variable; 
    }

}

Answer 5

This is the reusable function to wait for an element present in DOM using Explicit Wait.

public void WaitForElement(IWebElement element, int timeout = 2)
{
    WebDriverWait wait = new WebDriverWait(webDriver, TimeSpan.FromMinutes(timeout));
    wait.IgnoreExceptionTypes(typeof(NoSuchElementException));
    wait.IgnoreExceptionTypes(typeof(StaleElementReferenceException));
    wait.Until<bool>(driver =>
    {
        try
        {
            return element.Displayed;
        }
        catch (Exception)
        {
            return false;
        }
    });
}

Answer 6

Was searching how to wait in Selenium for condition, landed in this thread and here is what I use now:

    WebDriverWait wait = new WebDriverWait(m_driver, TimeSpan.FromSeconds(10));
    wait.Until(d => ReadCell(row, col) != "");

ReadCell(row, col) != "" can be any condition. Like this way because:

• it's mine
• allows inlining
