c# - Downloading a file with Watin in IE9

Question

I'm having an issue with automating the process of downloading a file from a website. The website has a Java button, that when clicked, triggers the download of an Excel file. I'm using the most recent build of Watin (v2.1).

I've managed to get Watin to log into the website, navigate to the appropriate page, change parameters on the page, and click the button to start the download.

However, when the download has completed, the IE9 download box appears, and nothing happens, until Watin timesout.

I'd appreciate any suggestions as I can't see any way of downloading a file, or getting it to save the file. Even if it passed 'Alt+S' to the page, that would save it. I've tried running it through WatinTestRecorder and that doesn't prompt for saving.

using (var browser = new IE(sLogin))
{
    browser.AddDialogHandler(new OKDialogHandler());
    browser.AddDialogHandler(new DialogHandlerHelper());
    browser.AddDialogHandler(new ConfirmDialogHandler());
    browser.AddDialogHandler(new ReturnDialogHandlerIe9());

    browser.TextField(Find.ByName("txtUserID")).TypeText("username");
    browser.TextField(Find.ByName("txtPassword")).TypeText("password");
    browser.Button(Find.ByName("btnLogin")).Click();

    browser.WaitForComplete();  
    browser.GoTo(targetUri);

    browser.SelectList("ctl00_phFormContent_ucOptionParam0_lst").SelectByValue("4");

    browser.Button(Find.ByName("ctl00$phFormButtonBar$btnRun")).Click();
    browser.WaitForComplete();

    //Some code to download the file here!
}

Answer 1

This should be supported since version 1.1.0.4000. The release notes for that version aren't online anymore (http://watin.org/documentation/), but I found it in Googles cache (http://svn6.assembla.com/svn/ci-samples/dotnet/watir/website/releasenotes-1-1-0-4000.html)

It should be something like:

using(IE ie = new IE(someUrlToGoTo))
{
    FileDownloadHandler fileDownloadHandler = new FileDownloadHandler(fullFileName);
    ie.AddDialogHandler(fileDownloadHandler);

    ie.Link("startDownloadLinkId").Click();

    fileDownloadHandler.WaitUntilFileDownloadDialogIsHandled(15);
    fileDownloadHandler.WaitUntilDownloadCompleted(200);
}

EDIT: After the comments below, this answer was accepted. So I'm assuming the following code works (which is taken from the link to SourceForge in my last comment, notice the ClickNoWait):

using(IE ie = new IE(someUrlToGoTo))
{
    FileDownloadHandler fileDownloadHandler = new FileDownloadHandler(fullFileName);
    ie.AddDialogHandler(fileDownloadHandler);

    ie.Link("startDownloadLinkId").ClickNoWait();

    fileDownloadHandler.WaitUntilFileDownloadDialogIsHandled(15);
    fileDownloadHandler.WaitUntilDownloadCompleted(200);
}
