You can accomplish this by the following code..

Thread workerThread = null;
void Save(object sender, ExecutedRoutedEventArgs e)
{
workerThread = new Thread(new ThreadStart(doWork));
SaveButton.isEnable = false;
workerThread.start();
}

do all your lengthy process in dowork() method

in some other method...

workerThread.join();
SaveButtton.isEnable = true;

This will cause to run save lengthy process in another thread and will not block your UI, if you want to show an animation while user click on save button then show some progress bar like iPhone etc... give me feedback i'll try to help you even more.
