How to check if an element is visible with WebDriver

Question

With WebDriver from Selenium 2.0a2 I am having trouble checking if an element is visible.

WebDriver.findElement returns a WebElement<

Answer 1

If you're using C#, it would be driver.Displayed. Here's an example from my own project:

if (!driver.FindElement(By.Name("newtagfield")).Displayed)      //if the tag options is not displayed
    driver.FindElement(By.Id("expand-folder-tags")).Click();    //make sure the folder and tags options are visible
