DelegateBindings
Easy property bindings using delegates, with the help of Nito.Mvvm.CalculatedProperties.
How to use it
First you need view models implemented like this:
public class RootViewModel : INotifyPropertyChanged
{
private readonly PropertyHelper properties;
public RootViewModel()
{
properties = new(RaisePropertyChanged);
}
public event PropertyChangedEventHandler? PropertyChanged;
private void RaisePropertyChanged(PropertyChangedEventArgs args) =>
PropertyChanged?.Invoke(this, args);
public string Text
{
get => properties.Get("");
set => properties.Set(value);
}
public ObservableCollection<Item> Items =>
properties.Get(() => new ObservableCollection<Item>());
}
public class ItemViewModel : INotifyPropertyChanged
{
private readonly PropertyHelper properties;
public ItemViewModel()
{
properties = new(RaisePropertyChanged);
}
public event PropertyChangedEventHandler? PropertyChanged;
private void RaisePropertyChanged(PropertyChangedEventArgs args) =>
PropertyChanged?.Invoke(this, args);
public string Content
{
get => properties.Get("");
set => properties.Set(value);
}
}
Then, it's just as simple as calling the binding like this:
using static DelegateBindings.DelegateBinder;
// ...
var binding1 = Bind(() => label1.Text = viewModel.Text);
var binding2 = Bind(() => label2.Text = viewModel.Items.FirstOrDefault()?.Content);
Whenever viewModel.Text
changes, label1.Text
will be changed as well.
It also works for observable collections. Whenever the Items
list is updated,
or the first item's Content
is updated, label2.Text
will also change.
Remarks
- The
Bind()
method receives anAction
, not anExpression
, which means you're not limited to just assignments. It's recommended that you keep the actions simple tho. - The view models MUST be implemented with Nito.Mvvm.CalculatedProperties. If you're using other libraries, the bindings WON'T WORK.
- Bindings are one-way. I'm planning to add two-way binding in the future but
for now you can do two bindings like this:
Or, for UI controls (WinForms, WPF, etc), use events directy:Bind(() => viewModel2.Result = viewModel1.Text); Bind(() => viewModel1.Text = viewModel2.Result);
Bind(() => textBox.Text = viewModel1.Text); textBox.Validated += (_, _) => viewModel1.Text = textBox.Text;
