Example

The example below shows a general purpose method for adding Grammar objects synchronously and asynchronously, as well as adding a handler for LoadGrammarComplete events if needed.

private void AddGrammar(Grammar grammar, bool aSync) {

    if (aSync == true) {
        if (!_grammarRequestHandler) {
            _recognizer.LoadGrammarCompleted += new EventHandler<LoadGrammarCompletedEventArgs>(onLoadGrammarCompleted);
            _grammarRequestHandler = true;
        }
        _recognizer.LoadGrammarAsync(grammar);
    } else if (!_recognizer.Enabled) {
        _recognizer.LoadGrammar(grammar);
        UpdateGrammarTree(_grammarTreeView, _recognizer); //needed as we are synchronous
    } else {
        _recognizer.RequestRecognizerUpdate(new GrammarRequest(grammar, GrammarRequestType.LoadGrammar));
    }


}
public void onLoadGrammarCompleted(object sender, LoadGrammarCompletedEventArgs eventArgs) {
    //Update Grammar display upon completion of asynchronous grammar load.

    UpdateGrammarTree(_grammarTreeView, _recognizer);


}
