I am not able to locate the element inside the frame after switching to the correct frame. Here is my code, error and HTML sorce. If I right click on the frame and select This Frame -> Show Only This Frame then I am able to find the element in the default_content, but I need to find it without Show Only This Frame

browser.switch_to.default_content()  

browser.switch_to.frame(browser.find_element_by_id('DialogFrame'))

browser.find_element_by_css_selector('#_ctl12_btnExportCSV')

Error stacktrace:

NoSuchElementException Traceback (most recent call last) in ----> 1 browser.find_element_by_css_selector('#_ctl12_btnExportCSV')

Induce WebDriverWait() and wait for frame_to_be_available_and_switch_to_it()

Induce WebDriverWait() and wait for element_to_be_clickable()

WebDriverWait(browser, 10).until(EC.frame_to_be_available_and_switch_to_it((By.ID, 'DialogFrame')))
inptelement=WebDriverWait(browser, 10).until(EC.element_to_be_clickable((By.CSS_SELECTOR, '#_ctl12_btnExportCSV')))

You need to import below libraries.

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

The element #_ctl12_btnExportCSV is a __doPostBack enabled element.

As the element is within 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:

      WebDriverWait(driver, 20).until(EC.frame_to_be_available_and_switch_to_it((By.ID,"DialogFrame")))
WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.CSS_SELECTOR, "input[id$='btnExportCSV'][name$='btnExportCSV'][value='Scaricamento']"))).click()

    • Using XPATH:

      WebDriverWait(driver, 20).until(EC.frame_to_be_available_and_switch_to_it((By.ID,"DialogFrame")))
WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.XPATH, "//input[contains(@id, 'btnExportCSV') and contains(@name, 'btnExportCSV')][@value='Scaricamento']"))).click()

  • Note : You have to add the following imports :

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

  • Thank you both but unfortunately the solutions are not working. There is a timeout error when locating the element: – Marco Venè Dec 21 '20 at 19:22
