🔒 Selenium "Element could not be scrolled into view" error

[peak jetty]

I am attempting to click on a row in a table and keep getting this error even though the table row is clearly in view. After all code to navigate page I have this
parentTable = driver.find_element(By.CSS_SELECTOR , '#ctl00_MainContent_PMList_PMListGrid') row = parentTable.find_element(By.CSS_SELECTOR , '#ctl00_MainContent_PMList_PMListGrid_row0') row.click()

the webpage is made up of several nested tables (can't figure out how to copy code in inspector). I have tried scrolltoview and several other suggestions with no luck. Do I need to create an object for each layer of the table like the above? That's my next thought unless someone else has a better idea.

Remember to:

• Ask your Python question, not if you can ask or if there's an expert who can help.
• Show a code sample as text (rather than a screenshot) and the error message, if you've got one.
• Explain what you expect to happen and what actually happens.

:warning: Do not pip install anything that isn't related to your question, especially if asked to over DMs.

Closes after a period of inactivity, or when you send !close.

When you initially load up the site check the page source via print(driver.page_source) See if you can find the element in the print. If you can then try copying the full Xpath.

Sometimes when websites dynamically change (if it be redirects or other things that change the source html) it takes time for selenium to actually see the changes.

@finite stratus It's just odd I'm getting a "Element could not be scrolled into view" when the entire page fits in the view window

[finite stratus]

May i ask what website this is so i can have a look?

[peak jetty]

It's an internal website for work.

It is dynamic and changes based on the machinery selected. It displays preventative maintenance task that are due. Maybe an EC. function before the other statements would help.

[finite stratus]

Does the page (that you are trying to get the table) need to be loaded in from a parent site/redirect?

Also can we see the code. (if you need to remove the site and other pii please do).

!paste

Pasting large amounts of code

If your code is too long to fit in a codeblock in Discord, you can paste your code here:
https://paste.pythondiscord.com/

After pasting your code, save it by clicking the Paste! button in the bottom left, or by pressing CTRL + S. After doing that, you will be navigated to the new paste's page. Copy the URL and post it here so others can see it.

I'm pretty sure the information displayed on the page populates from an SQL server query

Are you asking for my whole code or the webpage code

[finite stratus]

Whole code. if its also right with you can you send some screenshots of the website front end.

With selenium and dynamic websites, anything that changes and anything that happens beforehand can be part of the issue.

[peak jetty]

Gotcha one moment and I'll see if I can post the front end

As well as the code for the webpage. Just have to redact some stuff

[finite stratus]

the html of the website doesn't really matter to much since its a dynamic website and anything can change.

webpage

information in the first table changes based on the combo box to the right, second table at the bottom populates when you click on a row in the first table

[finite stratus]

async def get_fresh_sc(driver:webdriver.Chrome, repeats:int=5):
        """
        Checks if the page source HTML changes. 
            :param driver: Driver session required to preform tasks.
            :param repeats: Maximum amount of tries to should check.
            :return: None.
        """
        wt_logger.debug(f"Checking page-source change. [Driver|{driver}, Repeats|{repeats}]")
        prev_iter = driver.page_source
        for _ in range(repeats):
            wt_logger.debug(f"Repeating check page-source. [Iter({_+1}/{repeats})]")
            if prev_iter != driver.page_source:
                wt_logger.debug(f"Page-source change detected, breaking loop. [Iter({_+1}/{repeats})]")
                break
            prev_iter = driver.page_source
            await asyncio.sleep(1)
        else:
            wt_logger.debug(f"No changes detected in page source. [Repeats|({_+1}/{repeats})]")

This is some code from my current project. The purpose of this code is to detected when the html of a site changes (really useful for dynamic websites). When you click the combo box, run the code above and when it detects a change try finding the first table. repeat this for the second table as well.

I will give it a shot. Thank you.

[finite stratus]

Its going to be hard to give a definitive solutions as each selenium project is custom made for each website. However i will try my best to help you solve this issue. If you have any other questions or need additional help on this topic, feel free to share here.

Additionally i urge you to read up on selenium waiting methods.
