Popup window handle in Selenium Web Driver using C#

Question

I have a "File Export" link and when I click it, it is opening a new child window with options like "Open File","Save File" and OK or Cancel buttons. When I manually go through the steps and hit enter key it works and the file gets saved, but when I automate nothing happens.

This is my code:

 //Click Export link
 driver.FindElement(By.Id("ReportViewer1_ctl01_ctl05_ctl01")).Click();
 //Switch to popup window
 driver.SwitchTo().Window(Driver.Instance.WindowHandles.Last());
 //Click Enter to accept save option
 driver.SwitchTo().ActiveElement().SendKeys(Keys.Enter);
 //Close child window
 driver.Close();
 //Switch back to Parent window
 driver.SwitchTo().Window(Driver.Instance.WindowHandles.First());

The problem is that the window is stuck in the parent window and I am not able to send "Enter" to the popup window

Since, file download is not native to browser it is not possible to handle with Selenium . Remember, Selenium is only a tool to automate browser. However, you can handle this with setting up profile.

FirefoxProfile profile = new FirefoxProfile();
WebDriver driver = new FirefoxDriver(profile); 

profile.setPreference("browser.helperApps.neverAsk.saveToDisk" , "application/octet-stream;application/csv;text/csv;application/vnd.ms-excel;"); 
profile.setPreference("browser.helperApps.alwaysAsk.force", false);
profile.setPreference("browser.download.manager.showWhenStarting",false);
profile.setPreference("browser.download.folderList", 2); 
profile.setPreference("browser.download.dir","e:\\SampleExcel");
