How can I avoid "no response from server URL" exception when using hub on Selenium remotewebdriver when object is not found? - selenium

Question

This is the code I am getting error on line 1. Instead of returning true or false it throws an exception " No response from server for url: http://test:4444/wd/hub/session/1382359342795/element
Getting error on line1 :
Boolean tInputElement = driver.FindElement(By.Id("locator")).Enabled;
if (tInputElement.ToString() == "True")
{
IWebElement InputElement=driver.FindElement(By.Id("locator"));
InputElement.SendKeys(InputData);
}
Please suggest how can I avoid no response error and catch objectnotfoundexception. Please note I am running this code using Hub.
This is how I got this working :
int _TotalTimeToWait = 0;
int TotalTimeToWaitinSecs = 40;
while (_TotalTimeToWait < TotalTimeToWaitinSecs && driver.FindElements(by).Count == 0)
{
Thread.Sleep(1000);
_TotalTimeToWait++;
}
if (_TotalTimeToWait == 0) { driver.FindElement(by).Click(); Thread.Sleep(2000); }
else { throw new ElementNotVisibleException(); }
_TotalTimeToWait = 0;

Answer 1

As far as i know, there is no property like Enabled for WebElement, but it does have a IsEnabled() method, so try:
if (driver.FindElement(By.Id("locator")).isEnabled())
{
IWebElement InputElement=driver.FindElement(By.Id("locator"));
InputElement.SendKeys(InputData);
}
Or something like:
IWebElement InputElement=driver.FindElement(By.Id("locator"));
if (InputElement != null && InputElement.isEnabled())
{
InputElement.SendKeys(InputData);
}
