I have a need to hide a guid used for an index on a .cshtml so I can get model binding on controls dynamically added with ajax (it’s a long story) (that was a mouthful)

I had a hard time finding the value in the hidden field; as it turns out, you can just get it by the attribute on the Selenium element like this:

IWebElement hiddenIndex = driver.FindElement(By.Id("MyControlName_0__Index"));
var indexValueToUse = hiddenIndex.GetAttribute("value");
