Selenium Webdriver wait on element click?

try this :

WebDriverWait wait = new WebDriverWait(driver , 1000) ;
wait.until(ExcepctedConditions.elementToBeClickable(ById("element"));

Element can be ID of any element present on the next page you are redirected to . Once Page loads fully then it will start executing your code .

Instead of Click you could try to use SendKeys. Unlike Click, SendKeys does not wait for the page to finish loading before resuming code execution. So you can do something like this:

WebDriverWait wait = new WebDriverWait(browser, new TimeSpan(0, 5, 0));

elem.SendKeys(Keys.Enter);    
wait.Until<bool>((_driver) =>
{         
     //Check here if results have loaded yet
     return true;
});

As a side note, I'm pretty sure Until takes in a IWebBrowser as an input, not an element, which is why you can't click on elem.

In addition to prestomanifesto's solution I can offer a less than ideal solution to that I implemented to solve this issue. It turns out it is throwing an exception - No Response etc... - so I just surrounded it in a try catch then waited for the popup to close, which seems to work fine.

You can substitute whatever you want in your loop, just make sure to put a counter in so it won't loop forever.

try
{
    element.Click();
}
catch
{
    cnt++;
    do
    {
      //wait for whatever
      cnt++;
      Thread.Sleep(1000);
      // Wait for 30 seconds for popup to close
    } while (!string.IsNullOrEmpty(browser.CurrentWindowHandle) && cnt < 30);
}
