I have an element :

            webElement = this.Driver.FindElement(By.Id(key));

 

(The element is not null : OK.)

 

I use SendKeys method.

 

When the state is

  • webElement. SendKeys(«abcd») à it’s ok

 

  • webElement. SendKeys(«abcd» + Keys.Enter) à it’s not ok! webElement is cleared !

 

The problem only occurs on the PC dedicated to testing, on my development PC no problem!

Does anyone already have this problem? and has already managed to get around it/resolve it?

 

 

Thank you

 

 

  David

Try using a tab instead of enter.    When you manually perform the operation what's the behavior?

Manuallly it’s ok

I must do Enter (api are call on Enter)

Wow interesting programed behaviour.    Maybe add a second sendKeys line with just the enter.
Else, the input string needs \n (a return) embedded with the input string.
webElement. SendKeys(«abcd»)
webElement. SendKeys(Keys.Enter)

Hello

 

Thanks

 

With 2 lines, I had already tried: same problem

 

With @”\n”, the field is no longer cleared, but the "Enter" is not done. Nothing happens

Hi David,

It seems like you're encountering an issue where the `SendKeys` method works fine when typing regular characters, but when you add `Keys.Enter`, the text is cleared on a test PC, while it works on your development PC.

This issue could be related to several factors:

1. **Browser/Driver Version Mismatch**: Ensure that the browser version and WebDriver version on your test PC are consistent with the versions on your development PC. Differences in versions can sometimes cause unexpected behavior.

2. **Focus Issue**: Sometimes, sending `Keys.Enter` might trigger a blur event or cause the focus to shift unexpectedly, leading to the element being cleared. You could try adding a small delay before sending `Keys.Enter`:
   
   ```csharp
   webElement.SendKeys("abcd");
   Thread.Sleep(100); // small delay
   webElement.SendKeys(Keys.Enter);
   ```

3. **JavaScript Event Listener**: There may be some JavaScript running on the test environment that reacts to the `Enter` key and clears the input. You could try to check if there are any event listeners attached to the element that behave differently in the test environment.

4. **Differences in WebDriver Settings**: Double-check any WebDriver configurations between the test PC and the development PC. Sometimes, small settings like timeouts or how WebDriver interacts with certain elements (e.g., focus settings) might lead to these differences.

5. **Workaround with JavaScript Execution**: If all else fails, you can try using JavaScript to manually set the value and trigger an `Enter` key event:

   ```csharp
   IJavaScriptExecutor js = (IJavaScriptExecutor)Driver;
   js.ExecuteScript("arguments[0].value = 'abcd'; arguments[0].dispatchEvent(new KeyboardEvent('keydown', {'key': 'Enter'}));", webElement);
   ```

Give these suggestions a try and see if the behavior changes on your test PC. Let me know how it goes!

Best regards,
Bava

Hello

 

Thank you.

 

I'm on this problem since this morning.

I tried via javaScript: the text is pasted but no Event is triggered.

 

in my tests, I use SendKeys(text + Keys.Enter) in several places: no problem.

This is the only input where I have this problem.

 

I tried "everything"

 

FYI, I do

  • js.ExecuteScript("arguments[0].value='" + test.User.ClientAt.ClientCredit + "';", inputCreditNumber); à text is pasted
  • if I click on the field, the field is cleared !!

 

Very strange … …

Hi David,

Actions actions = new Actions(driver); 
actions.moveToElement(webElement) 
 .click() // Click to focus the element (if necessary) 
 .sendKeys("abcd") //type text
 .sendKeys(Keys.ENTER) //hen press Enter 
 .perform();  

Above steps should work without any issue in any environment.

Regards,
Jamuna Velusamy

Hi David,

I understand you’re facing a tricky issue where SendKeys("abcd" + Keys.Enter) clears the input field on your testing PC, but everything works fine on your development machine. Based on what you’ve shared, here’s a summary and some additional suggestions that might help you resolve this:

Summary of the Issue:

      •     When you use SendKeys("abcd"), the input works correctly.
      •     However, when you combine the input with Keys.Enter (i.e., SendKeys("abcd" + Keys.Enter)), the field is cleared, and the expected Enter action does not occur.
      •     This issue only happens on one specific input field and only on the test PC. Other inputs handle SendKeys correctly.
      •     You’ve already tried several workarounds, including using two separate SendKeys calls (SendKeys("abcd") followed by SendKeys(Keys.Enter)), using the Actions class, and setting the value via JavaScript. However, the field either gets cleared or the Enter key doesn’t trigger as expected.
      •     The field is cleared when you click on it after using JavaScript to paste text, which suggests there may be event listeners or custom behavior specific to the test environment.

Potential Cause:

Since the issue only occurs on the testing PC, it could be related to differences in the browser, WebDriver versions, or environment-specific configurations. There may also be some event listeners or JavaScript that handle Enter differently on this PC, causing the field to clear unexpectedly.

Suggestions for Resolving the Issue:

      1.    Test in Another Environment:
If possible, try running the same test in another test environment (e.g., a different machine or a cloud-based testing service like BrowserStack or Sauce Labs). This can help determine whether the issue is specific to the test PC’s setup (browser, WebDriver, OS configurations) or if it’s something in the test script itself.
      2.    Ensure Browser/Driver Consistency:
Check the versions of the browser and WebDriver on both your development PC and the test PC. If they differ, this could be the root cause of the issue. Update the test PC’s browser and WebDriver to match those on your development PC, and test again.
      3.    Disable JavaScript on the Test PC Temporarily:
If there is JavaScript that reacts to the Enter key (for example, an event listener that clears the input on Enter), it could be causing the field to clear. You could temporarily disable JavaScript in your test environment to see if this changes the behavior.
      4.    Test Different Browsers:
If possible, test the same script in different browsers (e.g., Chrome, Firefox, Edge) to see if the issue is browser-specific. This may also help reveal whether it’s an issue with the browser’s handling of SendKeys.
      5.    Focus Handling:
Since the field clears after you click on it, it might be that SendKeys shifts focus unexpectedly. Try explicitly setting focus on the element before using SendKeys. For example:

webElement.Click(); // Focus the element
Thread.Sleep(100);  // Small delay to ensure focus
webElement.SendKeys("abcd" + Keys.Enter);


      6.    Test on a Headless Browser:
If you are using a graphical browser for testing, you could try running the tests in a headless browser environment to see if the behavior changes. Headless browsers can sometimes handle focus and event issues differently, which might provide a clue as to what’s happening.

Final Thoughts:

If none of these suggestions work, it may be helpful to dive deeper into the test PC’s environment or configuration to identify what is causing the difference. Sometimes, subtle issues like keyboard layouts or operating system settings can affect how SendKeys functions. Running the tests in a cloud environment or using virtualization might help isolate the issue.

Let me know how things go after trying these out. Hopefully, we can get to the bottom of this soon!

Bava

Bavajith. Innocent question, but are you using genAI in your responses? Just asking because openers like "I understand you’re facing a tricky issue" and "it seems like you're encountering an issue where" are very typical of tools like ChatGPT?

Hello selenium-user,

Haha, you caught me! 😅 You’re absolutely right—I’ve been using AI to assist with troubleshooting. I figured, why not use it as a tool to help identify solutions more quickly?

I hope it doesn’t come across as disingenuous, but AI has really been useful in isolating issues and facilitating conversations that lead to resolutions. At the end of the day, my goal is always to find the best solution for the problem, and sometimes AI speeds that up. Even if it means the credit goes to the AI, I just hope David finds the solution to the issue at hand.

Thanks,

Bava

Hi, 

did you try running the Driver as admin.?

I think it’s pretty pointless to answer user group questions with generated responses. People tend to believe they are interacting with a human instead of ai, particularly because that’s how you represent yourself.

Hello

 

I don’t use process to running the Driver, just driver = new EdgeDriver for ex.

 

How did you do that ?

 

 

Tks

Hey ddlionx,

Let’s please refocus on finding a solution for David’s issue. My AI-assisted response was meant to streamline the process and provide helpful input, and I believe that contributes more to the discussion than the current detour we’re on.

I appreciate your feedback, and I’ll aim to keep future responses more concise and to the point.


Hey David,

For running the WebDriver as admin, what you can do is launch your IDE (like Visual Studio) or command line with admin privileges. Here’s how:

Option 1: Run Your IDE as Admin

  • Close your IDE.
  • Right-click on the IDE icon (e.g., Visual Studio).
  • Select Run as Administrator.
  • When you run your tests from there, the WebDriver (like EdgeDriver) will inherit those admin rights.

Option 2: Run Command Line as Admin

  • Open Command Prompt or PowerShell, right-click it, and select Run as Administrator.
  • Run your tests from there, and it should work with admin privileges.

There’s no direct way to make WebDriver itself run as admin, but this should do the trick since it launches the browser with those permissions.

Hope this helps!

Cheers,
Bava

If a generated response has been assessed, refined, and reworded for the reply, what's the problem? 
I find 50% of generated responses are wrong but usually helpful: often with Gemini the response is based on outdated APIs but on further prompting it's improved.
