Winforms.Binder

Two-way binding for Winforms!

Example:

First of all, make sure your viewModel implement the INotifyPropertyChanged interface and notify of changes in your properties.

If your viewModel doesn't INotifyPropertyChanged, the binding will be control -> viewmodel direction only.

Then you will be able to:

myUserControl.BindTextTo(() => myViewModel.SomeViewModelProperty);

Which is the same as:

myUserControl.Bind(
() => myControl.Text,
() => myViewModel.SomeViewModelProperty);

You can indeed bind to any property as long as types coincide.

myUserControl.Bind(
() => myControl.Enabled,
() => myViewModel.SomeBoolProperty);

If property types don't coincide, you just:

myUserControl.Bind(
() => myControl.Enabled,
() => myViewModel.SomeStringProperty,
viewModelToControlConverter: v => control.Enabled // We don't want to modify the original value.
controlToViewModelConverter: v => v ? "Yes" : "No");

Pro-Tip Your bindings are async friendly, they automatically check for Winform control properties and applies this trick: https://msdn.microsoft.com/en-us/library/ms171728(v=vs.110).aspx#Anchor_0

For now there is just this basic level of bindings.

Ninja-Tip

You can, in fact, bind whatever with whatever, as long as they implement INotifyPropertyChanged, you would have to use:

BindingExtensions.Bind(
() => someObjectOfAnyKind.SomeStringProperty,
() => myViewModel.SomeStringProperty);

Or

myUserControl.Bind(
() => someObjectOfAnyKind.SomeBooleanProperty,
() => myViewModel.SomeStringProperty,
viewModelToControlConverter: v => someObjectOfAnyKind.SomeBooleanProperty // We don't want to modify the original value.
controlToViewModelConverter: v => v ? "Yes" : "No");

Whatch out! DON'T USE BindingExtensions.Bind ON CONTROLS IF YOU ARE GOING TO DO ASYNC OPERATIONS!
