[FindsBy(How = How.Id, Using = "SomeID")]
public IWebElement SearchButton { get; set; }

now , I would like to use the wait.until for the element above. any way I can do that? Thanks Yaniv

You can create an abstract page object as parent to your page object and call an abstract method, which is implemented in the children pages, from the constructor:

public abstract class AbstractPage
{
    protected AbstractPage()
    {
        WaitUntilExist();
    }

    protected abstract void WaitUntilExist();
}

public class MyPage : AbstractPage
{
    [FindsBy(How = How.Id, Using = "SomeID")]
    private IWebElement SearchButton;

    public MyPage()
    {
    }

    protected override void WaitUntilExist()
    {
        wait.Until(ExpectedConditions.ElementExists(By.Id("SomeID")));
    }
}

The method WaitUntilExist() will be called from the parent constructor before the elements initialization in the child page. Since it's abstract the method in the child class will be excuted.
