copied!<p>The framework can automatically bind any events which require EventHandler types. However, for any events which require a templated EventHandler (with custom EventArgs) then you are correct - you'll need to include a custom Binding.</p> <p>The good news is that custom bindings are easy to write and to include.</p> <p>For example, to bind:</p> <pre class="lang-csharp prettyprint-override"><code>public event EventHandler<View.LongClickEventArgs> LongClick; </code></pre> <p>you can include something like:</p> <pre class="lang-csharp prettyprint-override"><code>public class LongPressEventBinding : MvxBaseAndroidTargetBinding { private readonly View _view; private IMvxCommand _command; public LongPressEventBinding(View view) { _view = view; _view.LongClick += ViewOnLongClick; } private void ViewOnLongClick(object sender, View.LongClickEventArgs eventArgs) { if (_command != null) { _command.Execute(); } } public override void SetValue(object value) { _command = (IMvxCommand)value; } protected override void Dispose(bool isDisposing) { if (isDisposing) { _view.Click -= ViewOnLongClick; } base.Dispose(isDisposing); } public override Type TargetType { get { return typeof(IMvxCommand); } } public override MvxBindingMode DefaultMode { get { return MvxBindingMode.OneWay; } } } </code></pre> <p>Which can be configured in setup using something like:</p> <pre class="lang-csharp prettyprint-override"><code> protected override void FillTargetFactories(IMvxTargetBindingFactoryRegistry registry) { base.FillTargetFactories(registry); registry.RegisterFactory(new MvxCustomBindingFactory<View>("LongPress", view => new LongPressEventBinding(view))); } </code></pre> <hr> <p>Note that you can't write a single class that binds to all the different event types - as the compiler requires you to include the correct Type for the EventArgs. However, you could fairly easily change <code>public class LongClickEventBinding</code> to something like <code>public class CustomEventBinding<TViewType, TEventArgsType></code> if you wanted to.</p> <hr> <p>With regards to what argument you should pass into the IMvxCommand Execute method, I guess this depends a bit on the method in question, and it also depends on whether you need the ViewModel to support multiple platforms, or whether it is just for Android.</p>
