Selenium WebDriverIE Sending single character as Lowecase - string

Question

I have recently changed from Windows 7 to a Windows 10 machine and, when running a previous Cucumber unit test pack that was working fine, I am now experiencing issues with SendKeys - which is causing all tests to fail unexpectedly. SendKeys seems to be sending the first character of a string as a ToLower().
Example:
string User = "ANALYSTUSER"
I am sending keys as:
SendKeys(User) / SendKeys(User.ToUpper())
and it is always populating the field as aNALYSTUSER!
I have rolled back the NuGet Package/driver version through the latest 10 versions and the issue still occurs. (I have also tried the 64-bit driver.)
Selenium.Support
Selenium.WebDriver
Selenium.WebDriver.IEDriver
Does anybody have an idea as to what may cause this and what can be tried here?

Answer 1

Perhaps the issue relates to your website client side JavaScript, it will change the entered value, I have created a sample using the following code, it works well on my side. You could have a try:
private const string URL = #"https://www.bing.com/";
private const string IE_DRIVER_PATH = #"E:\webdriver\IEDriverServer_x64_3.14.0"; // where the Selenium IE webdriver EXE is.
static void Main(string[] args)
{
InternetExplorerOptions opts = new InternetExplorerOptions() { IntroduceInstabilityByIgnoringProtectedModeSettings = true};
using (var driver = new InternetExplorerDriver(IE_DRIVER_PATH, opts))
{
driver.Navigate().GoToUrl("https://www.bing.com/");
var element = driver.FindElementById("sb_form_q");
element.SendKeys("WEBDRIVER");
Console.ReadKey();
}
}
Besides, you could also try to execute the script to enter a value, code as below.
private const string URL = #"https://www.bing.com/";
private const string IE_DRIVER_PATH = #"E:\webdriver\IEDriverServer_x64_3.14.0"; // where the Selenium IE webdriver EXE is.
static void Main(string[] args)
{
InternetExplorerOptions opts = new InternetExplorerOptions() { IntroduceInstabilityByIgnoringProtectedModeSettings = true};
using (var driver = new InternetExplorerDriver(IE_DRIVER_PATH, opts))
{
driver.Navigate().GoToUrl("https://www.bing.com/");
var element = driver.FindElementById("sb_form_q");
var script = "document.getElementById('sb_form_q').value = 'webdriver';";
IJavaScriptExecutor jse = (IJavaScriptExecutor)driver;
jse.ExecuteScript(script, element);
//element.SendKeys("webdriver");
element.SendKeys(Keys.Enter);
}
}
