I have seen couple of question posted on this topic but none of the solution worked that's why I am posting it again.
I am using WatIn to automate the testing of my website. Using IE 11. I have to download and save the file, but I am not able to click the save or saveas button of the download window. I tried FileDownloadHandler of WatIn but it didn't worked.
I am not limited to WatIn only solutions. It could be anything thing which I can use in my C# code will be acceptable
FileDownloadHandler fileDownloadHandler = new FileDownloadHandler();
browser.AddDialogHandler(fileDownloadHandler);
browser.Image(Find.ByAlt("Download.Csv")).Ancestor("a").ClickNoWait();
fileDownloadHandler.WaitUntilFileDownloadDialogIsHandled(40);
fileDownloadHandler.WaitUntilDownloadCompleted(200);
WatiN does not completely interact with Windows controls and help in windows is very little. I had the same problem in handling the windows controls as we had multiple versions of IE. IE 9.0 and higher have different file handling when compared to <= IE 8.0 version. The below works fine for IE 9.0 and higher.
Please make sure proper references are added (refer using's).
